Hi, Lois!
I'm so sorry about your father. I've been there, so I know how hard it is. My father died of cancer (colon cancer, which had spread) 16 years ago, and I still miss him.
I must say I'm a bit paranoid about skin cancer, being of a "fish-belly-pale" complexion, with hints of red (moreso when I was young) in my hair.
I had what I (but not my doctor) considered to be a suspicious mole (itchy at times, looking like it changed shape, and not even there 8 years ago!) removed from my back this summer. Left a not-so-nice round spot a bit smaller than the size of a dime, but was non-malignant. I just didn't want to worry about it.
With the thinning of the ozone layer, the sun's rays are most definitely more dangerous than they were in the 60's, for example.
Thanks for the timely reminder.
