It sounds like your doctors are being thorough by following up with more tests. Even though your test results were good, a good doctor makes sure there's nothing else going on.
Make sure to ask plenty of questions. The lump is in
your body, you should know as much as possible.
If the surgeon recommends no surgery, ask: Why do you feel it's ok to leave the lump? What is the type of lump I have? Will it grow? Can it become malignant? Does having this lump indicate that I will develop other breast problems?
Once you know the name of the lump, find as much information as you can.
If the surgeon suggests that the lump be removed, ask him why this is the best option. If at any time you question the recommendations of the surgeon, you are free to get a second opinion.
It is your right to request or refuse surgery. But don't underestimate the knowledge of medical professionals. They deal with these matters every day and will most likely act in your best interest.
In my case, to make a long story short, I was scheduled for a biopsy. My surgeon recommended that he not perform the biopsy, but instead remove the lump. That proved to be a vitally important and excellent call.
Let me know how things go.
