What is infiltrating ductal carcinoma?

Infiltrating (or invasive ) ductal carcinoma, known as IDC, is the most common form of breast cancer, accounting for 80% of invasive cases. It starts in the milk ducts of the breast and then breaks through the wall of the duct and invades the fatty tissue of the breast.

Infiltrating means that the cancer has spread to the surrounding breast tissues. Ductal means that the cancer began in the milk ducts, which 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. All together, IDC refers to cancer that has broken through the wall of the milk duct and begun to invade the tissues of the breast.

According to the American Cancer Society, more than 180,000 women in the United States find out they have infiltrating breast cancer each year. Most of them are diagnosed with infiltrating ductal carcinoma. Although infiltrating ductal carcinoma can affect women at any age, it is more common as women grow older. About two-thirds of women are 55 or older when they are diagnosed with an invasive breast cancer.

Consult with your doctor and you can better cope with the disease.
