"What did I save you for," the doctor asked Dan, "if not for you to have a life?"
Melanoma brain tumor 4-1/2 years ago, the original prognosis was not good. Surgery, radiation, rehab, ... then back to the boat, with prognosis excellent. He wears long-sleeve sunblock shirts from LL Bean, long lightweight pants, wide-brim hat, and SPF50 on hands & face. The doctor said that all the damage likely originated in childhood on the farm, but also said that with precautions - and religiously adhering to six-month checkups - nothing was precluded. Even with bimini, be aware of reflected sunlight off the water and put sunblock under your chin.
So if it wasn't precluded for him, its hopeful that you also can get back to your hobby. Wishing you the best, and hoping to see you on the water.
