So I'll make my comments a fresh post, for what they might be worth....
I was expecting a direct descendent of Grandma & Grandpa K. to respond with some specifics, but it has become apparent that the once often-read EJK Blog now gets very limited readership. I feel it is primarily due to the emergence and popularity of FACEBOOK and other social media which dominate people’s screen time.
Grandpa K. had diabetes, type 1, and took daily insulin and died at age 66. I recall no sign of cancer in him, nor in Grandma K. but I am not positive. She died at age 89 and, again, no written evidence left of any cancer. I think (not positive) Uncle Jay was 79 when he died and I recall no mention of cancer as a cause.
My own father, Ralph, died at age 80 and died from non-cancer causes. He did, however, have 2 or 3 cancerous skin lesions removed from his face during his last 10 years of his life.
I myself have had 2 significant subcutaneous skin lesions. In 2007, one subcutaneous cancerous spot (about the size of a nickel), diagnosed as “subcutaneous tissue, right cheek, excision (letigo maligna, melanoma in situ) – incidental small congenital intradermal nevus 1.5 x 1.2 cm" ….removed and skin-grafted over.
(In March of 2016, I had 2 early-cancer lesions removed from my scalp simply by freezing.) Then, in Oct. of 2016 I had “exc. of skin malignant 2.1 – 3 cm facial skin lesion removed from upper right cheek” (Dr.’s written conclusion) and about the size of a pencil eraser head). Also melanoma in situ. Although these 2 significant lesions were near each other, the 9 elapsed years between indicated there was no direct connection to each other.
Beyond the above, I cannot speak for my siblings, living aunts/uncles, or of my other cousins.
