Breast cancer is a kind of cancer that begins as a growth of cells in the breast tissue.
But breast cancer doesn't just happen in women.
Everyone is born with some breast tissue, so anyone can get breast cancer.
Signs and symptoms of breast cancer may include a breast lump or thickened area of skin that feels different from the surrounding tissue.
Thickening or swelling of part of the breast and irritation or dimpling of breast skin might be other signs.
