This is an interesting article. I knew of a family that was nearly all wiped out by cancer. One family member was my sister's best friend. She had leukaemia and died at 13. Her younger brother and sister both lived into their early 30's but both died of cancer. Their elder half sister(on the father's side) died of cancer along with their mother(thought the cancer gene was on the dad side).

I did think it was like a curse indeed.
