Stage 4 melanoma used to mean you'd be dead in a year. I personally know someone who was flat-out cured of stage 4 melanoma.
Her only treatment was three doses of immunotherapy. Her tumors shrank by two-thirds almost immediately. For the next seven years they just monitored, and finally they declared her cancer-free. She doesn't even have to go in for scans anymore.
Nah, she probably has some genetic damage already that lead up to that cancer. CT scans are 70x more radiation than X-Rays and contribute to lifetime cancer risk.
