i know this is a little off key but i was wondering , and have wondered for a long time if anyone knows or has heard of any studies, showing a correlation between a person surviving a certain kind of cancer ,only to have a different type later on in life , i have spoken with several cancer survivors, and on a large scale many of them have had cancer more than once,,, i have brought this up to docs in the past and they tell me the same thing , ,,,there is no connection , anyway not tryin to be a downer , just very puzzled , if i remember correctly, our brother purgatory might have some insight on this , thanks guyz and gals......................dirt
