Breast cancer, the uncontrolled growth of cells in the breast, is the most common type of cancer among women, excluding skin cancer. Each year in the United States, nearly 200,000 women, and some men, are diagnosed with breast cancer.
Invasive ductal carcinoma (IDC) is a type of breast cancer. IDC starts within the ducts of the breasts, but will spread to, or "invade," other breast tissue.
Some rarer forms of IDC include:
- Medullary Carcinoma: This infiltrating breast cancer has a rather well-defined boundary between tumor tissue and normal tissue.
- Metaplastic Carcinoma: Also known as carcinoma with metaplasia, metaplastic carcinoma is a very rare type of invasive ductal cancer that includes cells that are normally not found in the breast, such as cells that look like skin cells or cells that make bone.
- Mucinous (Colloid) Carcinoma: Also known as colloid carcinoma, this rare type of invasive breast cancer is formed by mucus-producing cancer cells.
