What are the main symptoms of breast cancer?

Maybe none: Early breast cancer has no signs or symptoms. Breast cancer may later present as a painless firm breast lump. Rarely changes in color of the skin, sometimes nipple will get retracted or breast skin pulled inward. Best is to have yearly physical examination and mammogram after age 40 before these symptoms occur. Any breast lump, painful or not, should be examined by your doctor.

Oftentimes, none: Oftentimes, breast cancers are found with routine mammography. By getting yearly mammograms, differences in the breast tissue can be visualized with the mammogram. In some instances, women may feel a new mass in their breast, notice a growing mass in the breast, or potentially have spontaneous bloody nipple discharge. These are only some symptoms; make sure to get breast exam if concerned.
