My story is a lot like bjohnson511. It was found on my routine mammogram. I was originally told surgery and 16-20 radiation treatments. The lump actually turned out smaller than first thought and lymph nodes were clear. I only had to do five radiation treatments as well. I tolerated them well. Luckily it was detected very early. In hindsight, I feel like this was the easy part for me (and I can't believe I'm saying that as it was very traumatic). The estrogen blocker for 5 years is turning out to be even more traumatic for me anyway. The list of possible side effects of these drugs are scary. The first one brought terrible jaw pain which started gradually after about 10 days and built up and became intolerable at almost 30 days. I just started a second one. Only a few days in at this point.
