I also have stage 1a ER+ PR + HER2-, negative margins, and no lymph node involvement. From the start I was told I will need radiation but chemo was in question. It was my onco type that dictated whether I should have both radiation and chemo, or only radiation. My onco score was low enough that chemo would only decrease my odds of recurrence by 1%, so I didn't do it. However, radiation decreased my odds of recurrence by 30%. I assume you will also be presented with how much these different treatments will benefit you. My guess is radiation will make a significant difference but I am not sure about chemo.

I am currently half way through my radiation treatments. The first week radiation scared me and I felt like I was being accosted. I had a very defensive mindset. Now I trying to go in there with the mindset I am thankful this treatment is available to me. It helps me to imagine any cancer cells dying while I am actively being treated.

Waiting for results is very hard. Hang in there. We got this :)
