I had the breast cancer with her2 negative. Tumor was at 3 and 1 lymph node positive and 1 with a very small amount. No chemo. Radiation was to make sure that there is no more cancer in my body. I didn’t have any issue. Went to work and radiation after work for 6 weeks. Hormone therapy pills for 5-7 years. Hope it goes well with you. This is my journey.
