@williamfh I had stage 3 melanoma on my shoulder in 2015. Surgery was successful and lymph nodes were removed. This was a year after my breast cancer and radiation.
A little over 5 years later melanoma metastasized in my lung and is inoperable. I started on keytruda in 2021 and will be on it for life. Within the first several treatments no sign of the tumor so there is no doubt Keytruda is a miracle drug.
