Intraductal Carcinoma In Children
Cancer is a group of diseases that is characterized by uncontrolled cell growth leading to invasion of surrounding tissues that spread to other parts of the body. Cancer can begin anywhere in the body and is usually related to one or more genetic mutations that allow normal cells to become malignant by interfering with internal cellular control mechanisms, such as programmed cell death or by preventing ...Read more
Yes BUT: There is debate about stage 0 breast cancer and how diff it is now vs how we found it 10-20 yrs ago. Some say smaller, low grade lesions shouldn't be called "cancer". Hi grade dcis certainly has risk of invasion over time. There are complementary treatments offered. Fam history & risk reduction should be considered. Tough to find cohort of pts w/ grade 2-3 dcis for whom radiation not beneficial. ...Read moreSee 1 more doctor answer
What is the normal timescale in finding a breast cancer and being operated on? In relation to 5mm of intraductal carcinoma grade 3?
Varies: This can depend on your overall health, your surgical risks, timing of getting a surgeon consultation. Availability of the operating room, scheduling with radiology to localize such a small lesion of 5 mm. Etc. This may take 1-3 weeks to schedule depending on these and other potential factors. ...Read moreSee 2 more doctor answers
Intraductal Papillary Mucinous Neoplasm on pancreas. 3mm. Same for 2 1/2 yrs. Cancer? Dr only follow with MRI. Should it be removed?
Good question: This may or not be a cancer, but without changes in appearance in 2 1/2 yrs and not knowing your complete medical history I would suggest that you follow your physician's plan and to feel better emotionally ask him/her to refer you to an oncologist for a second opinion. It is not unusual for doctors to agree to this request. ...Read more
For a 5mm intraductal breast cancer with 1mm of invasion, taken at lumpectomy and then a mastectomy performed, how many lymphs should be removed?
It depends: The current standard is to perform a sentinel lymph node biopsy; if (+), additional nodes are removed (unless radiation therapy planned, which would not be the case with this minimal tumor). The median number of sentinel nodes people have are 2-3, however some have 1, others can have many more--this does not reflect the tumor but rather the way the breast drains towards the armpit. ...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 it possible for breast high grade ductal carcinoma insitu (dcis) to spread to the major organs?
Dx w/ invasive ductal carcinoma er + & pr +. Grade 2. Waiting on DCIS. Meeting w/ two oncologists & surgeon. What do I ask??
Depends tumor size: If tumor small and was non palpable but only defined on mammogram, if lesion with intraductal components smaller than 1 cm, and sentinel node bx neg. I would wait to hear about margins. Margins that are adequate about 1cm around lesion suggests lesion in high 90% cure without RT. If larger lesion then possibly RT and tamoxifen. ...Read more
In one word unknown: Ductal carcinoma in situ dcis is simply the sleeping cancer cells inside the breast ducts, like a garden hose loaded with cancer cells safe if they are inside the duct, once they are out side then is invasive cancer, ready to spread, cause is unknown at this time, from genetic mutations, braca I & ii age, hormonal uses. Environment, late age pregnancy life style etc are all attributed. ...Read moreSee 1 more doctor answer
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. For more info:

You are right: Ordinarily, mastectomy is not necessary for precisely the reasons you have mentioned. So the standard treatment is excision of the dcis followed by radiotherapy to the affected breast. The only exception may be, if there are multiple dcis lesions in one breast....So unless you have this type of dcis, you do not need a mastectomy. ...Read more
Approx. How long would it take for dcis to spread to the lymph nodes? I have heard it is a fairly slow growing cancer.
It varies: When it's found, 1 case in 100 has metastasized. There must have been a few cells that got through the basement membrane that the pathologist didn't find -- or the primary may have regressed. But don't mess around with a dcis diagnosis. Choose the option that is right for you -- and you'll be offered a choice. ...Read more
Should tamoxifen be stopped if it caused endometrium thickening? Taking it for dcis, will it lead to endometrium cancer if continued?
In a female in their 20's the discovery of dcis is unusual and raises possibility of the need for prevention of other breast disease with tamoxifen
furthermore endometrium cancer is very unusual in a women on tamoxifen of this age and particularly if she still has periods
most doctors if concerned by thickening will do a biopsy and resolve the concern. ...Read more
Should tamoxifen be stopped if it caused endometrium thickening? Taking it for dcis, will it lead to endome cancer if continued? Asking about mom 54yr
It depends...: Endometrial thickening does not equal cancer. Tamoxifen can be continued but the endometrium should be investigates with consultation with a gynecologist. Tamoxifen should be discontinued only if the endometrial biopsy shows any atpia. But the best guidance should come from a gynecologist. ...Read moreSee 1 more doctor answer
