I don't mean to change the theme of this thread, but I've noticed that there is often a confusion between Infammatory
breast cancer. I went online and am posting a description of the others here.
[font="arial, verdana, helvetica, sans-serif; font-size: 13px; "] What is invasive breast cancer? Invasive breast cancer is cancer that spreads outside the membrane of the lobule or duct into the breast tissue. The cancer can then spread into the lymph nodes in the armpit or beyond to the brain, bones, liver, or lungs.
When breast cancer cells are found in other parts of the body, the cancer is called metastatic breast cancer.
There are several types of invasive breast cancer, including: Invasiveductal carcinoma (IDC).
With IDC, cancer cells start in a milk duct, break through the duct walls, and then invade fatty breast tissue. IDC can remain localized, which means it stays near the site where the tumor originated. Or the cancer cells may enter the bloodstream or lymphatic system and metastasize -- spread -- anywhere in the body. Invasive ductal carcinoma
is the most common type of invasive breast cancer. It accounts for 80% of invasive cancers. Ductal carcinoma in situ (DCIS).
This cancer is ductal carcinoma in its earliest stage -- stage 0. In situ means the breast cancer hasn't spread beyond its point of origin. That means the cancer is confined to the milk ducts and has not invaded nearby breast tissue. If it is left untreated, though, it can become invasive cancer. Infiltrating (invasive) lobular carcinoma (ILC).
This cancer accounts for about 10% to 15% of invasive breast cancers. ILC starts in the lobules or milk glands. It then spreads in a way similar to IDC. With ILC, most women feel a mass or thickening instead of a breast lump.
