What are the symptoms of in-situ breast cancer?
In situ breast cancer is a very early form of the disease, in which cancerous cells remain in the place of origin, in the lining of the ducts or lobules. Symptoms of in situ breast cancer include a lump, an area of thickening, an area of firmness, or a change in the size, shape or texture of the breast. In some cases, there may be no obvious signs or symptoms. A diagnostic mammogram or other imaging test is required for diagnosis. Treatment of in situ breast cancer usually involves surgery to remove the cancerous tissue and may be followed by radiation or hormone therapy.
