I think the question of heredity was discussed here earlier, with no real conclusion. I have been trying to get information on high cholesterol having a part in the development of liver problems - my mother had very high GOOD cholesterol and so do I, and I've read that cholesterol may play a part in liver malfunctioning.
My sister is convinced that she and I will die any minute from some kind of cancer, as my father died a week after my mother - of a rare brain cancer. Before that, no one really had cancer in my family. I'm not as full of doom and gloom about it, as it seems cancer can strike anyone at any time. But it does make you wonder, doesn't it? My husband's family has a bad history of breast cancer, yet the survival rate is amazing with early detection and education. Hopefully we can do the same for cc. It's a rare cancer but becoming more rare every year - the cases are increasing at an alarming rate, so hopefully someone will look into the heredity factor - and, more importantly, a cure!!! Here's hoping-
