Breast Cancer Symptoms: In its early stages, breast cancer usually has no symptoms. As a tumor grows, you may notice these signs: 1. Lump in your breast or underarm A lump in your breast or underarm that doesnt go away after your period. This is often the first symptom of breast cancer. Lumps associated with breast cancer are usually painless, although some may cause a prickly sensation. Lumps are usually visible on a mammogram long before you can see or feel them. 2. Swelling in the armpit, collarbone, or breast Swelling in your armpit or collarbone could mean breast cancer has spread to lymph nodes in that area. This swelling may come before you feel a lump, so let your doctor know if you notice it. Swelling in your breast might signal an aggressive type of cancer called inflammatory breast cancer. 3. Pain or tenderness in your breast Although lumps are usually painless, pain or tenderness can be a sign of breast cancer. 4. A flat or indented area on your breast This could be a tumor that you cant see or feel. 5. Breast changes You might notice a difference in the size, contour, texture, or temperature of your breast.
