Pathologists also look for the number of mitotic figures (tumour cells dividing to create new tumour cells). [4][5] It has been diagnosed in a significant percentage of men (see male breast cancer). In-situ carcinoma with duct and lobular features means that the in-situ carcinoma looks like DCIS in some ways and LCIS in some ways (when looked at under the microscope), and so the pathologist can’t call it one or the other. The nuclear grade is important because grade 3 (high grade) ductal carcinoma in situ is associated with a higher risk of developing invasive cancer compared to grade 1 (low grade) ductal carcinoma in situ. Learn more about treatment for early invasive breast cancer. Surgery for DCIS removes the abnormal tissue from the breast. Higher grade DCIS (the DCIS cells look abnormal) appears more likely than lower grade DCIS (the DCIS cells look similar to normal cells) to progress to invasive cancer after treatment [19]. For this reason, it is very rare to find cancer cells in another part of the body. Breast cancer. Local excision alone without irradiation for ductal carcinoma in situ of the breast: a trial of the Eastern Cooperative Oncology Group. J Clin Oncol. It is also called pre-invasive, non-invasive, or intraductal cancer.

Learn about DCIS, its symptoms, risk factors, diagnosis, grading and treatment. In order to make the diagnosis of DCIS, all of the tumour cells must be located inside the ducts. [27] If a lumpectomy is used it is often combined with radiation therapy. Ductal Carcinoma in Situ (DCIS), also known as intraductal carcinoma, accounts for one of every five new breast cancer diagnoses. [35], Cases of DCIS have increased five-fold between 1983 and 2003 in the United States due to the introduction of screening mammography. ER and PR are special tests that the pathologist does that are important in predicting response of the DCIS to hormone therapy (like tamoxifen). In-situ carcinoma with duct and lobular features . The lobes are further divided into smaller lobules that produce milk for breastfeeding. Histopathology of the cribriform type of breast ductal carcinoma in situ. They get little benefit from treatment, beyond peace of mind. In general, a higher number means more advanced disease and a worse prognosis. Breast cancer supportive therapy and survivorship. Breast Cancer: DCIS. Lymph nodes aren’t usually removed. “In situ” means “in place”. Rates of new cases of DCIS in the U.S. seem to be decreasing slightly over time.

This system uses information about the primary tumour (T), lymph nodes (N), and distant metastatic disease (M) to determine the complete pathologic stage (pTNM). For this reason, it is very rare to find cancer cells in a lymph node. potentially highly aggressive) lesions. In some cases, DCIS may become invasive and spread to other tissues, but there is no way of determining which lesions will remain stable without treatment, and which will go on to become invasive. These are special tests that the pathologist sometimes uses to help make the diagnosis of DCIS. For more information about DCIS on komen.org, please visit: Δdocument.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); Breast Care Helpline: However, if cancer cells are found in one or more lymph nodes your pathologist will provide a nodal stage between 0 and 3 based on the number of lymph nodes that contain cancer cells, the number of cancer cells found in the lymph node, and the location of the lymph nodes with cancer cells. With treatment, the prognosis for DCIS is usually excellent. Materials and Methods A stratified random sample of women who underwent breast-conserving surgery .

This is my first time here and I could use some help. [7] DCIS encompasses a wide spectrum of diseases ranging from low-grade lesions that are not life-threatening to high-grade (i.e. A positive margin is associated with a higher risk that the tumour will grow back (recur) in the same site after treatment. Ductal carcinoma in situ (DCIS) now represents 20-25% of all 'breast cancers' consequent upon detection by population-based breast cancer screening programmes. However, DCIS can sometimes cause signs such as: DCIS is usually found on a mammogram and appears as small clusters of calcifications that have irregular shapes and sizes. Visser LL, Groen EJ, van Leeuwen FE, Lips EH, Schmidt MK, Wesseling J. Predictors of an invasive breast cancer recurrence after DCIS: a systematic review and meta-analyses. When your breast was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. [35], Some institutions that have encountered high rates of recurrent invasive cancers after mastectomy for DCIS have endorsed routine sentinel node biopsy (SNB). DCIS is considered the earliest form of breast cancer. The location you tried did not return a result. Diferenciación entre CLIS y afectación lobulillar por CDIS (Tabla 1).

These women have an excellent prognosis with a very low risk of DCIS recurrence or developing breast cancer in the opposite breast. This is a term used to describe a cancer that begins in the lining layer (epithelial cells) of organs like the breast. Mayo Clinic is a not-for-profit organization. Ductal Carcinoma In Situ is non-invasive breast cancer that occurs in the milk ducts of the breast. Once the carcinoma cells have grown and broken out of the ducts or lobules, it is called invasive or infiltrating carcinoma. Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. Similar to ductal carcinoma in situ, lobular carcinoma in situ begins—and remains—in the cells that line the breast lobules (the glands that make milk). [12][13], Ductal carcinoma in situ (DCIS) literally means groups of "cancerous" epithelial cells which remained in their normal location (in situ) within the ducts and lobules of the mammary gland. 387(10021):866-73, 2016. [38][39], With treatment, the prognosis is excellent, with greater than 97% long-term survival. A sentinel node biopsy is done just in case invasive breast cancer is found in the breast tissue removed during surgery. Sort by: Most popular.

The factors associated with the progression of ductal carcinoma in situ (DCIS) to invasive breast cancer are poorly understood. In comedonecrosis, the dead cells are in the centre of a duct and surrounded by living cells. Mod Pathol. Ductal carcinoma in situ (DCIS) is a neoplastic proliferation of mammary ductal epithelial cells confined to the ductal-lobular system without evidence of invasion through the basement membrane into the surrounding stroma (Arch Pathol Lab Med 2009;133:15) Is a nonobligate precursor lesion of invasive breast cancer (Breast Cancer Res Treat 2010;123:757, Cancer 2005;103:2481) DCIS has been classified according to the architectural pattern of the cells (solid, cribriform, papillary, and micropapillary), tumor grade (high, intermediate, and low grade), the presence or absence of comedo histology,[8] or the cell type forming the lesion in the case of the apocrine cell-based in situ carcinoma, apocrine ductal carcinoma in situ. DCIS is noninvasive, meaning it hasn't spread out of the milk duct and has a low risk of becoming invasive. [10][11] It is the most common type of pre-cancer in women. Ductal carcinoma in situ (DCIS) is the earliest possible form of breast cancer. Accessed May 23, 2018.

Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. DCIS is non-invasive because it hasn't spread beyond the milk ducts into other healthy tissue. 171(3):777-781, 2018. [24], There are different opinions on the best treatment of DCIS. Also, women who have never had children or had them late in life are also more likely to get this condition. Diseases of the breast. 88 Carcinoma ductal in situ de la mama - Víctor Acosta y col. . Without treatment, DCIS cells could progress to invasive cancer over time. If your report does not mention E-cadherin, it means that this test was not needed to make the distinction. The American Cancer Society is a qualified 501(c)(3) tax-exempt organization. With DCIS, the abnormal cells haven't broken through the walls of the milk ducts and haven't spread to nearby breast . "In situ" means "in place". What does nuclear grade mean and why is it important? If untreated, DCIS progresses to invasive cancer in roughly one-third of cases, usually in the same breast and quadrant as the earlier DCIS. 12(1):21-9, 2011. Cancer of the breast.

The results should be discussed with your doctor. Search doctors, conditions, or procedures . Because certain calcifications are found in areas containing cancer, their presence on a mammogram may lead to a biopsy of the area. Researchers are studying ways to predict which cases of DCIS will progress to invasive breast cancer. The movement of cancer cells from the tumour to a lymph node is called metastasis. We couldn’t do what we do without our volunteers and donors. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS). Lumpectomy for DCIS is usually followed by whole breast radiation therapy. Often, the first instinct is to act quickly. Radiation therapy is rarely given to women treated with mastectomy for DCIS.

Warren LEG, Chen YH, Halasz LM, et al. Breast Cancer Res Treat. Depending on the amount of breast tissue removed, the procedure may be called a ‘lumpectomy’ or a ‘mastectomy’.. Overall survival is the same after either treatment [2]. How we treat cancer. Currently, all DCIS lesions . (888) 552-6760 (888) 552-6760 CHAT NOW SCHEDULE A CONSULTATION. I have Grade 3 IDC highly ER positive 8/8 HER2 negative. DCIS starts in the tubes (ducts) of the breast that carry milk. This would allow some people at low risk to avoid treatments they don’t need. [28] Chemotherapy is not needed for DCIS since the disease is noninvasive. 2010(41):162-77, 2010. This means some people are over-treated for DCIS. After treatment for DCIS, there’s a small risk of invasive breast cancer, as well as DCIS recurrence [5]. At this stage, the cells have not broken through the walls of the milk ducts into the surrounding breast tissue. It’s also important to follow recommended screening guidelines, which can help detect certain cancers early. Many studies of this subject focus on the role of molecular and genetic alterations in the neoplastic epithelial cells. Paget disease (also called Paget’s disease, Paget disease of the nipple, or Paget disease of the breast) is when cells resembling the cells of ductal carcinoma in situ (DCIS) are found in the skin of the nipple and the nearby skin (the areola). Las mujeres con formas pequeñas y de bajo grado de esta neoplasia . In the context of "overdiagnosis" the low grade DCIS cases found on screening mammography are likely to cause the number of cases where the diagnosis of breast malignancy has been made but could conceivably not have been fatal to the patient . © 1998-2023 Mayo Foundation for Medical Education and Research (MFMER).

El informe anatomopatológico final mostró carcinoma ductal residual in situ de alto grado en la mama derecha y carcinoma lobulillar in situ en la mama izquierda. The larger the area of DCIS, the more likely it is to come back (recur) after surgery. When the entire area of DCIS is removed, the outside surface (edges or margins) of the specimen is coated with ink, sometimes even with different colors of ink on different sides of the specimen. Although the exact percentage is not known, it’s estimated about 20-50 percent of DCIS cases progress to invasive breast cancer if left untreated [24-28]. Ductal carcinoma in situ (DCIS) is the presence of abnormal cells inside a milk duct in the breast. Diseases of the Breast, 5th edition. The pathologic stage for ductal carcinoma in situ is based on the TNM staging system, an internationally recognized system originally created by the American Joint Committee on Cancer. Here you'll find in-depth information on specific cancer types – including risk factors, early detection, diagnosis, and treatment options. Description: Ductal carcinoma in situ (DCIS); drawing shows a lobe, ducts, and fatty tissue in a cross section of the breast. If DCIS is touching the ink (called positive margins), it can mean that some DCIS cells were left behind, and more surgery or other treatments may be needed. Ductal carcinoma in situ (DCIS) is the earliest stage of breast cancer. The milk ducts are the canals that carry milk from the lobules to the nipple openings during breastfeeding. . Sometimes, though, the surgeon has already removed more tissue (at surgery) to help make sure that this isn’t needed. The risk of recurrence depends on both patient charac- teristics, such as family history of breast cancer in a first degree relative and younger age at diagnosis, as well as on tumor. . The articles on this site are not a substitute for professional medical advice, diagnosis, or treatment and should not be relied on to make decisions about your health. Testing for ER is done for most cases of DCIS, but testing for PR is not typically needed. Doctors might describe DCIS in different ways. Your pathologist will carefully examine the tissue under the microscope to see where the tumour cells are located within the breast. DCIS is called non-invasive because, after careful microscopic examination, cancer cells were found only on the inside of the ducts and glands. If all the margins are negative, most pathology reports will say how far the closest cancer cells were to a margin. Breast anatomy. It's in situ, which means it does not spread to other healthy tissues from its point of origin. Learn more about medical care after treatment. [41] Biomarkers can identify which women who were initially diagnosed with DCIS are at high or low risk of subsequent invasive cancer. For example, many patients ask: Is DCIS hereditary? Any use of this site constitutes your agreement to the Terms and Conditions and Privacy Policy linked below. Systematic reviews (including a Cochrane review) indicate that the addition of radiation therapy to lumpectomy reduces recurrence of DCIS or later onset of invasive breast cancer in comparison with breast-conserving surgery alone, without affecting mortality. I had a tumor show up bad on mamm, 2nd mamm & ultrasound (#5 on Biard, suggesting malignancy, didn't know this . 28(5):662-669, 2015. Intraductal carcinoma is another name for ductal carcinoma in-situ. [13][17] When classified as a cancer, it is referred to as a non-invasive or pre-invasive form. This term is used for the earliest stage of breast cancer, when it is confined to the layer of cells where it began. Comedonecrosis is a special type of necrosis sometimes seen in DCIS. DCIS doesn't typically have any signs or symptoms. The growth potential of DCIS varies based on three grades: A DCIS diagnosis may also include information on the cancer’s hormone-receptor status. Collins LC, Tamimi RM, Baer HJ, Connolly JL, Colditz GA, Schnitt SJ. Most women with DCIS are not aware of any symptoms at the time of diagnosis. It is not cancer and may not become malignant.

If the entire tumor or area of DCIS is removed (such as in an excisional biopsy or breast-conserving surgery), the pathologist will say how big the DCIS is by measuring how long it is across (in greatest dimension), either by looking at it under the microscope or by gross examination (just looking at it with the naked eye) of the tissue taken out at surgery. Hughes LL, Wang M, Page DL, et al. Molecular tests may help predict the chances of DCIS coming back (recurring) in the breast, but not all cases need these tests. According to Dr. Polyak, “Even though DCIS by itself is not a life-threatening disease, understanding why some patients with DCIS develop invasive breast cancer while others do not would help our understanding of drivers of tumor progression and the design of more effective therapies.”. You can help reduce your risk of cancer by making healthy choices like eating right, staying active and not smoking. The metastatic stage can only be . After surgery and radiation therapy, some people take hormone therapy [5]. Until we do, we’ll be funding and conducting research, sharing expert information, supporting patients, and spreading the word about prevention. There are 2 main types of in-situ carcinoma of the breast: ductal carcinoma in-situ (DCIS) and lobular carcinoma in situ (LCIS). These are all different ways of describing how the DCIS looks under the microscope: Patients with higher grade DCIS may need additional treatment. However, emerging evidence suggests that transition from DCIS to invasive cancer is strongly . National Cancer Institute. Ductal carcinoma in situ (DCIS) is a non-invasive form of breast cancer, meaning that the abnormal cells are contained within the milk ducts of the breast and have not invaded the nearby breast tissue. However, in a small number of patients, some symptoms may occur, including: Any noticeable changes to a breast should be discussed with a doctor. Invasive ductal carcinoma is the most commonly diagnosed breast cancer and has a tendency to metastasize via lymphatics. [12][13]. Epidemiology. Additional tests may be used to determine whether the cancer is estrogen-receptor positive or negative—important information that helps the medical team predict whether the cancer may be treated with hormone therapy. . - Grado nuclear de las células tumorales: bajo, intermedio y alto- Patrón arquitectural de crecimiento: sólido, papilar, micropapilar, cribiforme . El carcinoma ductal in situ (DCIS, por sus siglas en inglés) es el crecimiento anormal de células en los conductos galactóforos (de leche) del seno (mama). We’ve invested more than $5 billion in cancer research since 1946, all to find more – and better – treatments, uncover factors that may cause cancer, and improve cancer patients’ quality of life. Factors that may play a part include your lifestyle, your environment and genes passed to you from your parents. Your pathologist will carefully examine all the margins in your tissue sample to see how close the cancer cells are to the edge of the cut tissue. It’s most commonly used in patients who’ve had a lumpectomy, since this treatment lowers the chances that the cancer will return. From 2013-2017, rates decreased by about one percent each year [4]. No obstante, tres semanas después de la mastectomía bilateral, la paciente continuó con el tratamiento adyuvante del bloqueo dual HER2 con trastuzumab (600 mg) y pertuzumab (420 mg). In this setting, cancerous means that there is an abnormal increase in the growth of the epithelial cells, which accumulate within and greatly expand the ducts and lobules ( Figure 1 ). Mayo Clinic does not endorse companies or products. With total mastectomy, the surgeon removes the entire breast, but no other tissue. Lancet Oncol. A clinical trial studying active monitoring as an alternative to surgery may be another option. At this stage, cancer is considered non-invasive. Asta inseamna ca celulele care acopera canalele s-au transformat in celule canceroase, dar nu s-au raspandit prin peretii canalelor in tesutul . info@komen.org, © 2023 Susan G. Komen is a 501(c)(3) non-profit organization. Tumours that do not make ER or PR are described as hormone negative. Researchers are looking at ways to predict which cases of DCIS are the most likely and the least likely to progress to invasive breast cancer. Paget disease of the nipple is usually associated with DCIS or invasive carcinoma (cancer) in the underlying breast tissue. Miller ME, Muhsen S, Zabor EC, et al. Margins will only be described in your report after the entire tumour has been removed. If you received treatment (either chemotherapy or radiation therapy) for your cancer prior to the tumour being removed, your pathologist will examine all of the tissue submitted to see how much of the tumour is still alive (viable). 32:3613-18, 2014. Treatment may include breast-conserving surgery combined with radiation or surgery to remove all of the breast tissue. [30][31][32] The Cochrane review did not find any evidence that the radiation therapy had any long-term toxic effects. According to the American Cancer Society, DCIS accounts for around 1 in 5 new breast cancer diagnoses. [14][18] The National Cancer Institute describes it as a "noninvasive condition".[13]. Algunas personas incluyen el CDIS en las estadísticas sobre el cáncer de mama. Treatment options for DCIS depend on a number of things, including the size of the DCIS compared to the size of the breast, the grade of DCIS, the woman's age and whether she has a family history of breast cancer. Abstract. Ductal carcinoma in situ (DCIS), also known as intraductal carcinoma, is a pre-cancerous or non-invasive cancerous lesion of the breast. All of these are terms for benign (non-cancerous changes) that the pathologist might see under the microscope. 30(12):1268-73, 2012. Ductal carcinoma in situ (DCIS) is a nonobligate precursor of invasive cancer, and its detection, diagnosis, and management are controversial. For example, the report may say that DCIS was found in 3 slides. 1-877 GO KOMEN Unfortunately, some cases of DCIS are over-treated.

Whenever possible, surgeons will try to cut tissue outside of the tumour to reduce the risk that any cancer cells will be left behind after the tumour is removed. Anastrozole for prevention of breast cancer in high-risk postmenopausal women (IBIS-II): an international, double-blind, randomised placebo-controlled trial. [3] It rarely produces symptoms or a breast lump one can feel, typically being detected through screening mammography.

Purpose To identify uptake and determinants of surveillance imaging in women who underwent treatment for DCIS. Book an appointment today! Treatment is aimed at getting rid of all the DCIS, usually by surgery. DCIS that is low grade, is nuclear grade 1, or has a low mitotic rate is less likely to come back after surgery. Then, when the biopsy is done, the pathologist looks at the tissue removed to be sure that it contains calcifications. Bethesda, MD. Some of these are linked to a higher chance that the DCIS may come back after treatment, so finding them may change your treatment. Long-term outcomes of invasive ipsilateral breast tumor recurrences after lumpectomy in NSABP B-17 and B-24 randomized clinical trials for DCIS. Because of the lack of early symptoms, DCIS is most often detected at screening mammography. The inset shows a normal duct and a duct with abnormal cells. DCIS is noninvasive, meaning it hasn't spread out of the milk duct and has a low risk of becoming invasive. Sin embargo, el CDIS puede ocasionar signos como los siguientes: Un bulto en la mama. DCIS doesn't typically spread to other parts of the body. [13] Tamoxifen may be used as hormonal therapy if the cells show estrogen receptor positivity. Information in this report will be used to help manage your care. DCIS is a non-invasive breast cancer, but it may progress to invasive breast cancer over time. Ductal carcinoma in situ (DCIS) DCIS means that some cells in the lining of the ducts of the breast tissue have started to turn into cancer cells.

Breast-conserving treatment with or without radiotherapy in ductal carcinoma in situ: 15-year recurrence rates and outcome after a recurrence, from the EORTC 10853 randomized phase III trial. The recommended treatment for DCIS is surgery, with or without radiation therapy [5]. Title: Ductal Carcinoma In Situ. Por lo general, el carcinoma ductal in situ no genera signos o síntomas. Guideline adherence has not been characterized in a contemporary cohort. Lymph nodes are not always removed for ductal carcinoma in situ.

Kane RL, Virnig BA, Shamliyan T, Wang SY, Tuttle TM, Wilt TJ. 15:890, 2015. Correa C, McGale P, Taylor C, Wang Y, et al. Available Every Minute of Every Day. Help us end cancer as we know it, for everyone. [30] While the authors caution that longer follow-up will be required before a definitive conclusion can be reached regarding long-term toxicity, they point out that ongoing technical improvements should further restrict radiation exposure in healthy tissues. This content does not have an English version. Hormone therapy isn’t recommended for women who have a mastectomy for DCIS [5]. So, almost all cases of DCIS are treated. Researchers don't know exactly what triggers the abnormal cell growth that leads to DCIS. Ductal carcinoma in situ is given a metastatic stage of 0 or 1 based on the presence of cancer cells at a distant site in the body (for example the lungs).

Es un tipo muy temprano de cáncer de seno no invasivo. DCIS has been classified according to the architectural pattern of the cells (solid, cribriform, papillary, and micropapillary), tumor grade (high, intermediate, and low grade), the presence or absence of comedo histology,[8] or the cell type forming the lesion in the case of the apocrine cell-based in situ carcinoma, apocrine ductal carcinoma in situ. Fort Washington, Pa.: National Comprehensive Cancer Network. Cancer Epidemiol Biomarkers Prev. On needle biopsy, measurements of the area of DCIS are not often reported because this type of biopsy only samples a part of the tumor. Distress management. Ductal carcinoma in situ (DCIS) is considered the earliest form of breast cancer. El carcinoma ductal in situ es una neoplasia epitelial maligna de la mama que se origina en las células de la unidad ductal terminal - lobular (TDLU) que crece dentro de los conductos o lóbulos pero está delimitada por la membrana basal, que no está infiltrada. In a needle biopsy, a needle is used to remove a sample of an abnormal area. Microcalcifications or calcifications are calcium deposits that can be found in both non-cancerous and cancerous breast lesions. Sometimes DCIS and LCIS are both found in the same biopsy. Ductal carcinoma in situ (DCIS) is the non-obligate precursor of invasive breast carcinoma. Estrogen-receptor status and risk of contralateral breast cancer following DCIS. Breast cancer screening (PDQ®)–health professional version. E-cadherin is a test that the pathologist might use to help determine if the carcinoma in situ is ductal or lobular. [22] Nonetheless, the risk of developing noninvasive cancer increases with age and it is higher in women older than 45 years. Women considered at higher risks are those who have a family history of breast cancer, those who have had their periods at an early age or who have had a late menopause. If the calcifications are there, the treating physician knows that the biopsy sampled the correct area (the abnormal area with calcifications that was seen on the mammogram). The exact cause of DCIS isn’t known, but some factors that may increase the risk of developing the disease. We don’t think that all DCIS would go on to become invasive cancer, but we can’t tell which DCIS would be safe to leave untreated. Ductal carcinoma in situ (DCIS) is the presence of abnormal cells inside a milk duct in the breast. DCIS is usually found during a mammogram done as part of breast cancer screening or to investigate a breast lump. 1-877 GO KOMEN With the increasing use of screening mammography, noninvasive cancers are more frequently diagnosed and now constitute 15% to 20% of all breast cancers. 103(6):478-88, 2011. 26(13):4317–4325, 2019. In situ means "in place" and refers to the fact that the abnormal cells have not moved out of the mammary duct and into any of the surrounding tissues in the breast ("pre-cancerous" refers to the fact that it has not yet become an invasive cancer). Learn more about hormone therapy for DCIS. There is not a one size fits all approach to breast cancer, and DCIS is no different. . In situ means in its original place.

In an invasive carcinoma, the tumor cells can spread (metastasize) to other parts of your body. BCS involves only removing the tumor and some of the surrounding tissue, while a mastectomy removes the entire breast, especially when the DCIS tumor is large. The specific causes of DCIS are still unknown. Please enter a valid 5-digit Zip Code. Long-term use of estrogen-progestin hormone replacement therapy (HRT) for more than five years after menopause, genetic mutations (BRCA1 or BRCA2 genes), atypical hyperplasia, as well as radiation exposure or exposure to certain chemicals may also contribute in the development of the condition. Continued observation of the natural history of low-grade ductal carcinoma in situ reaffirms proclivity for local recurrence even after more than 30 years of follow-up. Because ductal carcinoma in situ (DCIS) may develop into invasive breast cancer and invasive breast cancer can spread and cause death, it's recommended that all Comienza en los conductos lácteos y se propaga a los tejidos mamarios circundantes.

As long as the carcinoma cells are still confined to the breast ducts or lobules, and do not break out and grow into surrounding tissue, it is considered in-situ carcinoma (also known as carcinoma in situ, or CIS). Pathologists determine the grade for DCIS by looking at a part of the cell called the nucleus and comparing it to the cells normally found in the breast. A margin is considered positive when there are cancer cells at the very edge of the cut tissue. If DCIS affects a large part of the breast, a total (simple) mastectomy will be done. Intraductal carcinoma is another name for ductal carcinoma in-situ. About 15 percent of breast cancers in the U.S. are DCIS [1].
