One of the earliest signs of breast cancer can be an abnormality that shows up on a mammogram before it can be felt. The most common signs of breast cancer are a lump in the breast; abnormal thickening of the breast; or a change in the shape or color of the breast. Finding a lump or change in your breast does not necessarily mean you have breast cancer. Additional changes that may also be signs of breast cancer include:
• Any new, hard lump or thickening in any part of the breast
• Change in breast size or shape
• Dimpling or puckering of the skin
• Swelling, redness or warmth that does not go away
• Pain in one spot that does not vary with your monthly cycle
• Pulling in of the nipple
• Nipple discharge that starts suddenly and appears only in one breast
• An itchy, sore or scaling area on one nipple
