Breast cancer originates in your breast tissue. It occurs when breast cells mutate, creating a mass of tissue (a tumor). Like other cancers, breast cancer can invade and grow into the tissue surrounding your breast. It can also travel to other parts of your body and form additional tumors. When this happens, it’s called metastasis.
