Until you have a biopsy performed on your breast lumps and your left armpit lump, it is premature to give you a diagnosis of cancer. However, if the lumps in your left breast are due to breast cancer, then the lump in your left armpit may be caused by spread of breast cancer cells to one or more lymph nodes in your armpit.
You should obtain a biopsy of all of these lumps without delay!
