I can't recall the details from my thyroid cancer because I wasn't given much explanation and I was told I had to have my thyroid removed. I wasn't given any treatment choice. With the breast cancer, I had lump removal, was misdiagnosed, went to an oncologist who removed more margin and did a lymph node removal to verify that the cancer did not involve the lymph nodes. The readiation burned my skin badly so I had three days relief and treatment before they continued the radiation.
I was diagnosed with a paralyzed vocal chord 18 months after surgery on the thyroid and they said it was too late to rehab my vocal chord with therapy. They offered more sugery. I declined. The vocal sound has returned somewhat after many years, but doesn't have a pleasant voice sound. I can't rejoin the choir to sing. I don't worry about more cancer at my age. I eat an excellent anti-cancer diet and get what exercise I can manage.
