What causes ductal carcinoma in situ (dcis)?

What causes ductal carcinoma in situ (dcis)?

Viral insertion: DCIS is the earliest phase of transformation to malignancy developing in the ductal system before invasion into parenchyma has occurred. It is defined on mammo by clustered microcalcification. In general the long terminal repeat of the MMTV viral genome enters the ductal cell to initiate transformation. with time the cells become aggressive and invade basement membrane helped by the EBV virus ...Read more

Where does invasive ductal carcinoma metastasize?

Where does invasive ductal carcinoma metastasize?

Many organs: The first likely tissue where metastases occurs in invasive ductal cancer is the lymph nodes on the armpit or behind the chest wall. Other organs may include the bones, lungs, liver, brain, adrenal glands, skin, bone marrow, the lining around the lungs or heart or the abdomen. Other parts of the body are less often sites of spread. ...Read more

Ductal carcinoma deadly?

Ductal carcinoma deadly?

Stage-Dependent: Breast cancers are staged based upon the size of the cancer, lymph node or distant organ involvement, and unique molecular features of the tumor. Published rates of 5-yr survival (http://www.Cancer.Org/cancer/breastcancer/detailedguide/breast-cancer-survival-by-stage) vary quite a bit based on these variables, between 15%-93%. The type of cancer (ductal, lobular, etc) doesn't impact survival. ...Read more

What is left axillary lymph node metastatic adenocarcinoma?

What is left axillary lymph node metastatic adenocarcinoma?

Regional spread: Many tumors, as they evolve, develop the potential to spread. The lesions develop matrix metalloproteinase which forms small e-cadherin from the cell cement and allows for spread. Regional nodes are a common site and for lesions on the arm and chest, spread is to the axilla. Lt. breast carcinomas as they grow and spread frequently are noted in the left axillary lymph nodes as metastatic adenoca ...Read more

What is breast cancer sentinel node micro metastases?

What is breast cancer sentinel node micro metastases?

Spread of cells: Micrometastasis means that a few tumor cells have left the breast tumor and traveled to the lymph nodes under the arm. In most cases, this is treated as a negative lymph node. I encourage you to review your pathology report with your surgeon and oncologists (ideally they are communicating with each other through a meeting called a tumor board). ...Read more

What is metastatic breast carcinoma?

What is metastatic breast carcinoma?

Cancer 'elsewhere': Metastatic cancer is cancer that has spread from its organ of origin to another part of the body. For example, the most common sites of metastases for breast cancer are the lungs, liver, and bone. Most breast cancers, when caught early and treated in a timely manner, do not ever spread to other organs. ...Read more

Is dcis breast cancer genetic?

Is dcis breast cancer genetic?

It can be: Dcis, the earliest form of breast cancer, can be associated with brca mutations. 13% of women under 50 diagnosed with dcis had a brca mutation in retrospective (looking backwards) studies. Women with a family history of breast or ovarian cancer or dcis before age 50 should have genetic counseling.

What are the survival statistics for breast cancer invasive ductal carcinoma?

It depends on many f: Most women with localized breast cancer do very well and there is high cure rate. Overall 75%-80% of breast cancers are curable. But you need to know what stage of cancer it is? You should also know what subtype(there are 3 different types) of breast cancer it is. Further there is the matter of what type of adjuvant therapy(post surgery treatment) was used. I'am sure your oncologist can answeryr. ...Read more

Is metastatic squamous cell carcinoma genetic?

Is metastatic squamous cell carcinoma genetic?

Genetic component?: There could be genetic component to a squamous cell cancer, although the exact implications on treatment aren't known. Obviously if there is a strong family history of cancers, or if it strikes someone who is young and/or a non smoker/drinker i would suspect a strong genetic contribution. Without more details, it is hard to say with any certainty. ...Read more

No: Although both are breast cancers they are different in the significance attached to them. Lobular carcinoma is more likely to be larger, lymph node positive and estrogen positive then invasive ductal. A study in the ann surg oncol. 2010 jul;17(7):1862-9. Epub 2010 feb 17 suggests that invasive lobular carcinoma has a better prognosis stage for stage than invasive ductal carcinoma. ...Read more

What is mucin-producing metastatic colonic adenocarcinoma?

Subtype of colon Ca: Mucin producing metastatic adenoca of the colon is derived from a primary adenoCa of colon producing large amounts of extracelluar mucin with greater than a 50% mucinous component.. The proximal colon and appendix represents 10-20% of these colorectal neoplasms . The rt. colon is the usual source for most of these lesions presenting with more advanced forms of disease than other colonic sites. ...Read more

Breast cancer with lymph node involvement prognosis?

Depends: Lymph nodes are one aspect of evaluation for stage and treatment of breast cancer. It depends on size of breast cancer itself, number of lymph nodes involved, hormone status of the tumor, and dna testing can also help identify breast cancer risks. If the lymph node involvement is small, then there is little additioanl risk to the patient. There are many factors involved in assessing breast cancer. ...Read more
