Carter had secondary brain lesion from primary melanoma. Also lesions on his pancreas. He recrived immunotherapy in the formnof a drug combo of Yervoy and Keytruda. Went into remission almost immediately. My wife had the exact manifestations as Carter but six months earlier so Keytruda was not yet available for her. The Yervoy alone was not effective and the melanoma took her.
I’m so sorry for your loss.
God bless.
