As I mentioned earlier, it's very important that if you are going to spend a long time exposed to the sun and to the ultra violent rays, that you take precautional measures and preventive measures to prevent sunburn. I think the more important thing is also to decrease the risk of getting skin cancer. Just in the United States alone, over one million new diagnosed cases of skin cancers are found. Every year about 7,000-10,000 people die of skin cancer. That's why it's important that I emphasis that if you are going to be out in the sun, that you take the precautional measures and you should start at a very young age so that your children do the same thing, always put sun blockers on, always put all these things that we have discussed. I'm going to talk about the cause of skin cancer and then maybe go very briefly into the different types of skin cancer, how you can recognize it, and what you can do to treat it. The cause of skin cancer. How skin cancer starts. First of all, when the ultra violent light hits your skin, it penetrates and it hits the cells that are in your skin. The ultra violent then causes something....and I'm not going to go technically, but it causes a lot of increased free radicals in the cells. The free radicals is the enemy of the cells because they cause mutation in the genes of your cells. That's why that you've got to not allow that to happen. You've got to decrease that level of free radicals in your system from happening. It's the mutation that the free radical causes in the genes in your body that causes the skin cancer. Now, there are different ways that you can recognize skin cancer. People who are fair, fair skinned people with lots of freckles and moles have a higher predisposition or a higher risk at getting skin cancer than those people that are more tanned or more colored because that's because of melanin, which is a pigment in the skin cells that gives protection. An extra layer I guess of protection to the ultra violent rays penetrating into the cells.
