Lauren, my son was only 33 when he was diagnosed with SCC, a non smoker, living a healthy lifestyle with no hereditary possibilities for his OC. But even if it were hereditary, everyone is different in their reactions to OC so because someone else in your family has the same type of SCC, it doesn't mean your reaction is the same. My son's SCC was almost 8 years ago and he doing well, now. It's difficult not to worry about the "what ifs" - I do it, too- but I try to limit the time I think about it and switch over to all the positives in my son's survival. Keeping the stress level down is better for keeping you healthy, too.
