Breast cancer can have different symptoms, and some people may not have any signs or symptoms at all. However, some warning signs of breast cancer are:

• A new lump in the breast or underarm (armpit)
• Thickening or swelling of part of the breast
• Irritation or dimpling of breast skin
• Redness or flaky skin in the nipple area or the breast
• Pulling in of the nipple or pain in the nipple area
• Nipple discharge other than breast milk, including blood
• Any change in the size or the shape of the breast
• Pain in any area of the breast

It is important to note that these symptoms can happen with other conditions that are not cancer. Many conditions can cause lumps in the breast, including cancer, but most breast lumps are caused by other medical conditions. If you have any signs or symptoms, it is important to see your doctor right away. Regular screening tests for breast cancer are important, but mammograms do not find every breast cancer. Therefore, it is also important to know what your breasts normally look and feel like, so you can be aware of any changes in your breasts.
