Signs and Symptoms of Breast Cancer
Common symptoms include: painless lump, lump or swelling in the underarms, breast pain or heaviness, persistent changes of breast tissue such as swelling, thickening, or redness of the skin, and any nipple changes.
If the tumor is small, there are typically no symptoms, which is why screening is important.
