Stage3 womb cancer

Hi all, I have recently had a hysterectomy. I was diagnosed stage 1 but the histology report showed a tumour in the Fallopian tube so I was re diagnosed to stage 3 from stage 1 for a small cancerous polyp grade 3. I’m now facing both chemo and radiotherapy. It isn’t good news as I was hoping for just the hysterectomy and too then move on with my life. I have long hair so will lose it,, another shocker as well as toxic chemo but the cancer could be more toxic if it spreads. Not sure what to expect but apparently chemo is brutal?
