Radiation Therapy

It's all been very quick diagnosed with stage 1, grade 1 invasive breast cancer, ER+ then appointment with surgeon 2 days later, lumpectomy and removal of two lymph nodes 4 days after seeing surgeon. Currently day 3 after surgery, home recovering. Get results on lymph nodes and margins next week. 

I'm trying not to think too far ahead, but ... I worry about radiation (been told 5 days a week for 4 weeks) and how it will affect me as I work full-time. 

Any advise on what I can do to make the next stage of treatment easier and what to expect ☺️
