Breast cancer
Cancer that originates in mammary glands
Breast cancer is a cancer that develops from breast tissue. Signs of breast cancer may include: a lump in the breast, a change in breast shape, dimpling of the skin, milk rejection, fluid coming from the nipple, a newly inverted nipple, or a red or scaly patch of skin. In those with distant spread of the disease, there may be bone pain, swollen lymph nodes, shortness of breath, or yellow skin.
