Not any first hand experience myself, but my sister-in-law had these lumps throughout her life and her mother saw to it that she got several removed when she was a teen. Naturally that was a horrible experience, so as she grew up, she basically ignored them when they came back.
Two years ago she fell and had to have a chest x-ray--which revealed many of these growths. They told her it was an emergency to get the biopsy done. Once done, cancer was found, so they operated and removed both breasts! She now has implants and is doing well. They say they got all the cancer. She regrets not having taken care of herself.
I would say with your history, they should not put you off. Call back again and tell them if they end up waiting and at the worse, there is cancer, they could be libel. Maybe they will get you in a bit sooner.
Best wishes! Keep us posted.
