So. For a while my mom has had a hard lump in her under arm. Long story short. After trips to the doctors and hospital she had a biopsy earlier. Which showed a shadow on the opposite side to the lump. Around her breast and lymph node which they were both bigger than normal on both sides. The nurse said it looks like cancer. Waiting a week is very Worrying. Could it be something else causing this? As I can't find anything online. How is it treated? Will she still have a long life ahead of her?
