Hi, This is a good line of thought. I have always wondered why they do not look more at the ones who make it instead of the ones who do not.Some people never get a chance to fight it, it is moving to fast. Not just oral cancer.Wonder why?There are a lot of health factors figured in, but some people make it against the odds and others do not.Our body make up? Of course some people never live a healty lifestyle and live to old age never seeing Cancer. Maybe they should drag all these people in and do a study on them! I recently went to my family Doctor with a cold, he looked over my record and sent me up to X-ray. I grumbled about just needing antibiotics and cold medicine and then it hit me. I will never have a normal Doctor appointment again, Cancer alert every time. This is good but a big reminder we are never safe. The X-ray was clear, which is good.I do feel strange knowing this is the first thing they will look for every time I get a cold or anything else.Reality is sometimes not a pretty thing.
