Just an interesting footnote ...My mother's frien

Just an interesting footnote ...My mother's friend Helen ... Helen's family has a history of fatal brain tumors. A least 7 or 8 died from brain tumors (at every age). In late 60's early 70's her family was studied extensively by that famous Cleveland hospital. The information gathered was the basis that cancer could be inherited not just random. True story. She was the only one never to die from brain cancer.
