Hello again yourspecialmiss,
A biopsy is minor operation where the surgeon removes the lump (or part of it) and then sends a sample to the lab to see if the cells in the lump are actually cancerous. A lump can be many things from a cyst (fluid filled and non-cancerous) to fibrous (solid tissue, but still non-cancerous) to pre-cancer to cancer. One lump can also be composed of a combination of the above.
Although I had 2 distinct tumors, I also had tiny bits of cancer throughout the breast so I had my one breast removed (mastectomy). I had a plastic surgeon perform reconstructive surgery and now even in a bikini you can't tell I had the breast removed!
I am the only person in my family to have any kind of cancer. Just make sure that your Dr is thorough and finds out for sure one way or another what that lump is. Saying, "it's probably nothing" isn't good enough. Whenever I hear a Dr say "probably" I interrupt them actually
Ask for an ultrasound. This test is very easy to perform and will tell you if the lump is fluid filled or solid which is a good place to start. If it is solid, I think you should have a biopsy b/c there isn't any other way to know for sure if the cells are cancerous. In my experience, it was best to have the lump removed entirely and have the whole thing biopsied b/c part of my lump was non-cancerous and part of it was deadly. What if the surgeon only sampled the part that was benign?
I don't mean to frighten you, I just want you to make sure that you're ok!
No one looks out for us better than ourselves. I have found that especially at our age, people are much more likely to say, "it's probably nothing". I hope I don't sound like I'm down on Drs either, b/c the Drs that I ended up with saved my life. Unfortunately, I had to see some not-so-great Drs before I found them.
If you don't mind, pls post back to let me know how you are.
