The increase of mammogram screening has revealed more breast cancers than ever before. Still, mammograms can miss some breast cancers, and
many women only learn they have cancer when noticeable symptoms appear. The
most common symptoms include:
- a new breast lump or mass (painless and hard with irregular edges)
- a new breast lump or mass (tender, soft, and rounded)
- swelling (part or all of the breast, with or without a lump)
- swelling in an underarm lymph node
- skin indentions or dimpling
- skin irritation or inflammation
- skin redness, thickening, or scaliness
- nipple retraction
- nipple thickening
- non-milk nipple discharge (particularly blood)
- breast pain or nipple pain
- breast tenderness
- change in the size or shape of the breast
