The waiting is the worst part. If your lump is 2 cmm or less, it is probably in the early stages. Mine was 1.8 and I am Stage 1. I had a lumpectomy and am having radiation for 6 weeks. No chemo. I only missed 5 days of work. The fear was much worse than the reality so hang in there.
Once my biopsy results came back positive, they ordered a cat scan, a bone scan, and a mri to be sure the cancer is isolated to my right breast. The news was good so I could opt for a lumpectomy rather than a mastectomy. When I had the lumpectomy, they removed my sentinal lymph node which is located in my underarm to check for cancer cells. It came back negative. They sent a sample of my tumor to Calif. for an OncoType DX test. This test is for early stage and node negative breast cancer and will give your doctors information about whether you would benefit from chemo. Years ago everyone got chemo but not so today.
Demand the information you need from your doctors. If you are not comfortable with them, get different doctors. Your peace of mind depends on being informed and confident in the care you are receiving. Get the book, "Just Get Me Through This" which discusses what to expect with early stage breast cancer.
Best of luck on your journey back to health.
