Non Invasive Ductal Carcinoma In Situ
INVASIVE or DCIS?: These terms are incongruous: dcis is, by definition, breast cancer that has not "broken out" of the ducts and entered the adjacent supportive tissue of the breast; invasive, or infiltrating ductal cancer, by definition, has. The treatment of these 2 diseases is quite different since there is a risk of systemic disease with the latter. Please clarify, thanks. ...Read moreSee 2 more doctor answers
Depends on where this diagnosis was made. Is a non-invasive disease. Ductal carcinoma in situ of the breast is treated with lumpectomy and sometimes hormone therapy & radiation. Lobular carcinoma in situ of breast is treated as a benign pre-cancerous lesion. Cancer in situ of the colon treated as an early cancer with surgery. Gynecologist can answer this ...Read more
"in place": Ductal carcinoma in situ (DCIS) of the breast is a breast cancer which has started in the ducts of milk glands (as most breast cancers do) but not yet invaded beyond that into the fat of the breast. Untreated, it has a high likelihood of becoming invasive breast cancer, a potentially fatal disease. Treated DCIS has a high cure rate. Some with DCIS benefit from taking med to prevent 2nd cancer. ...Read more
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
Genetic mutations: This is mostly a random event. There's a natural instability in the human genome even if you are never exposed to anything that's obviously a mutagen. The other factors that place you at risk for breast cancer (nulliparity, brca1 / brca2 mutations, etc.) are risk factors here, but no woman (and actually no man either) is immune. ...Read more
Is ductal carcinoma in situ really breast cancer? Can lifestyle, nutrition or supplements affect its course or occurrence?
Precancerous: Carcinoma in-situ is just one step short of cancer. There is no scientific evidence for or against life style changes altering the course of in-situ lesions. You may engage in life style changes that promote a healthy life style but should not omit conventional treatment. Steve jobs low grade cancer became fatal while he tried to treat it by alternative methods. See your doctor. ...Read moreSee 2 more doctor answers
What is the meaning of multifocal ductal carcinoma in situ, left breast and right subdural hematoma?
cancer and clot: Multifocal means mutiple seperate sites of cancer cells in the ducts or tubes of the breast. In situ means the cancer has not spread outside the ducts, into the surrounding breast tissue. In this instance the problem is in the left breast. Subdural hematoma is a blood clot between the brain surface and the membrane (called dura) covering the brain. In this instance the clot is the right side. ...Read more
It depends: Tumors that are grade 3, or that have a high "proliferation rate", may spread more quickly than grade 1 or 2. Tumors that are er- (estrogen receptor negative) or her2+ spread more quickly than other types. Inflammatory breast cancer of any type can spread in days; the other types of invasive ductal carcinoma generally take months. ...Read moreSee 1 more doctor answer
Means localosed in place. Medical terms is for carcinoma "localized and did not spread out" it is really description of precancerous condition with bad name that disturbs many patients. Carcinoma in situ is not a killer. If left untreated will develop into invasive cancer ...Read more
