How do I know if I could be at risk? what about all the moles on my body? I hear that they have something to do with it all.
If you get too much radiation, then you can have it. The most visible sign is a black mole. If you notice a black mole, see a doctor about it.

skin cancer is known as melanoma, this site will give you good information.
Not all moles are cancerous. You can have a lot of moles though out your body and not have cancer but, you need to keep an eye on it…
If there is increase in size, change in color, change in borders (irregularities), the size should NOT exceed the eraser size on the back of a pencil..
Symptoms…well, you should not have bleeding or itching from a mole.
Of course, use SPF protection when under the sun. Can't really say there are risks …..unless you're always under the sun (lifeguard etc).
well go 2 a doctor
it the brown spots are bigger then an pencil eraser,that,s what my teach er said to me once.
well if you really think you have skin cancer you should go see a doctor cause if you actually do it should get removed so it doesn't spread to the rest of your body

Get a skin check by a qualified physician. Fair skinned people who easily burn are at high risk. Asymmetrical moles or patches of skin that don't heal well could be signs.
My grand mother who was a nurse died from skin cancer
that website is reliable and trustworthy. it tells you all the signs and symptoms and what to look for to know if you are developing skin cancer/melanoma. as far as moles go. The mole itself isnt a "sign", you should watch for any mutations of moles to be able to know whether u may or may not have skin cancer.
Cancer is less prone to grow in a stress free body. so minimize stressful situations, and if needed, find techniques that work for you stay calm during stressful times. things like meditation, yoga, breathing techniques are a good start. get plenty of rest and relaxation will help during stressful times.
Avoid chemical exposure. some chemicals are worse than others. The ethylene chloride, a potent solvent are on the worst list, so are pesticides, detergents, and things we eat like artificial sweeteners. Young children are most susceptible to chemicals.
Eat organic whole foods. this means eating foods in their natural form, not processed and without pesticides. If you must eat non-organic make sure and wash them good to remove the pesticides. Peeling helps, the wax they use to make the fruit or vegetable look shiny acts as a barrier so washing won’t get rid of the pesticides.
Cigarettes are a know cause of many types of cancer. so if you smoke, stop. this could not only save your life but the lives of many others around you.
Avoid indoor pollution. In the newly built homes, you're fairly safe. In older homes you can buy test kits or take samples in to a local lab and have them tested. In some jurisdictions, houses built before 1978 will have traces of lead based paint under a few layers; just make sure that it's not peeling and you should be fine. If you have radon present, ventilate your home. If you have formaldehyde present remove the source or use an air purifier. If you have asbestos in your home have it professional removed or encapsulated. Store other chemicals properly.
Take vitamins- vitamins a, E, K, B?, C, and D, or better yet, eat the foods rich in these vitamins.
Drink plenty of water. The normal person needs about 80 ounces of water a day.
Tips
See your doctor at least once a year for a routine exam. Discuss any changes in your health with your doctor.
Warnings
This is not intended to be a substitute for medical treatment.
Avoid SUGAR! Cancer grows through a fermentation like process to survive and requires glucose. Reducing the amount of sugar will help prevent cancer. "Natural" sugar is chemically the same, so do not be fooled; what nutrients fruits/honey/grains have can be obtained in greater quantities via vegetables without all the harmful sugar/starch. see the link below to numerous studies regarding sugar and cancer and Nobel winner Otto Warburg's research proving this connection.
