My grandpa was diagnosed with melanoma two years ago. He had treatment and surgery, we though it was gone but it came back and was worse than before. He did more treatment and surgery. He still has melanoma.
Him getting melanoma could have been avoided by wearing sunscreen when he was growing up.
Melanoma is a skin cancer caused by the sun.
