I was 72 when I was diagnosed with stage 1, not remembering all the details at this hour, but it was in the duct, hadn't reached the lymph nodes, and was told there was no need for chemo, radiation was optional and I would be on an AI for 5 years. I have scar tissue in my lungs and was told they couldn't protect my lungs from the effects of the radiation. The oncologist said the detriment of not taking radiation was .05 percent greater per year - so I opted out and just went with the AI.
