Invasive ductal carcinoma Larger Version
Invasive ductal carcinoma (IDC), sometimes called infiltrating ductal carcinoma, is the most common type of breast cancer. About 80% of all breast cancers are invasive ductal carcinomas.
Invasive means that the cancer has “invaded” or spread to the surrounding breast tissues. Ductal means that the cancer began in the milk ducts, which are the “pipes” that carry milk from the milk-producing lobules to the nipple. Carcinoma refers to any cancer that begins in the skin or other tissues that cover internal organs — such as breast tissue. All together, “invasive ductal carcinoma” refers to cancer that has broken through the wall of the milk duct and begun to invade the tissues of the breast. Over time, invasive ductal carcinoma can spread to the lymph nodes and possibly to other areas of the body.
According to the American Cancer Society, more than 180,000 women in the United States find out they have invasive breast cancer each year. Most of them ...
Ductal carcinoma in situ (DCIS) is the most common type of non-invasive breast cancer. Ductal means that the cancer starts inside the milk ducts, carcinoma refers to any cancer that begins in the skin or other tissues (including breast tissue) that cover or line the internal organs, and in situ means "in its original place." DCIS is called "non-invasive" because it hasn’t spread beyond the milk duct into any normal surrounding breast tissue. DCIS isn’t life-threatening, but having DCIS can increase the risk of developing an invasive breast cancer later on.
When you have had DCIS, you are at higher risk for the cancer coming back or for developing a new breast cancer than a person who has never had breast cancer before. Most recurrences happen within the 5 to 10 years after initial diagnosis. The chances of a recurrence are under 30%.
Women who have breast-conserving surgery (lumpectomy) for DCIS without radiation therapy have about a 25% to 30% chance of having a recurrence at some po...
When you hear the words “breast cancer,” what’s your first impression (besides dread)? Do you picture your mother, sister, or girlfriend? Film footage of legions of pink-ribbon bedecked women striding through the streets of a major city, television coverage of one of the big breast cancer fund-raising walks? Do you ever see a man in this picture? No? We often speak about the sisterhood of breast cancer. Well, move over ladies–men get breast cancer, too. Not nearly as often as women, admittedly; while about 200,000 American women are diagnosed with breast cancer each year, the figure for men is about 1,300, a little over half of one percent of the total. But for those 1,300 men, the diagnosis is just as searing; the treatment as painful, the illness just as life-threatening. In fact, statistics show breast cancer diagnosis in a man is actually more life-threatening, due to the fact it was probably made later, and the cancer is usually more advanced. The vast major...
