NO! Don't worry!
NO. Intraductal carcinoma is not transmissible.
Pre-Cancer aka DCIS. Intraductal cancer, aka ductal-carcinoma-in-situ (dcis), is cancer that both arises and stays within the milk ducts of the breast; this is in contrast to invasive cancer, which has exited the ducts & into the supportive breast tissue. Therefore, by definition, dcis cannot exit outside the breast. Left untreated, this may progress to invasive cancer. Rx includes lump-x (+/-rt) vs. Mastectomy.
Noninvasive. Intraductal carcinoma is a noninvasive condition in which abnormal cells are found in the lining of a breast duct. The abnormal cells have not spread outside the duct to other tissues in the breast.
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.
Yes. Natural treatments for cancer abound--unfortunately, none of them have been proven to work. The "natural" course for breast cancer leads to death.
