I've had cancer throughout my reproductive organs, and melanoma cancer on my arm. In both cases, I opted for major surgeries - and they worked. It took five surgeries in each region (10 surgeries total) to get rid of all of it, over the course of one year, but ultimately, it worked. I have a major 8" jagged scar on my arm that crosses over and around my elbow, but it was completely worth it to be cancer free. I'm almost three years cancer-free in both regions.
That same year, I also had a 3/4" breast tumor which turned out to be benign, but I had it removed, lest it become cancerous. I have three small scars from that.
After the hysterectomy, my sexual chemistry changed dramatically and now I feel like a eunuch. But having zero sex drive is actually a huge relief and makes life more simple.
I don't regret any of the surgeries I had. The surgeries meant I could avoid chemo and radiation, and keep my hair. I'm so grateful I had good health insurance that was actually willing to pay for surgery. Chemo/radiation cost less money and that's why they're often pushed first by health care systems.
So I recommend surgery over radiation. Radiation can rot your bones and teeth and cause so many problems down the line, so I would avoid it at all cost.
