My legs have developed blot..

My b-ball team has been conditioning everyday out in the sun for the past two months and I haven't been wearing sunscreen (because I never have). Now, I'm starting to see all these darker blotches on my legs (they look like faded scars). I'm pretty sure that its because I haven't been protecting myself from the sun (i'm going to go and buy sunscreen today) but I was wondering how can I get rid of it and also, is it related to skin cancer?

Thanks

I recommend visiting a dermatologist. The legs are a common place for skin cancer to appear, although it is usually the result of years of exposure. That being said, it is always a good idea to involve a professional if something seems unusual. The visit will give the doctor an opportunity to treat your current symptoms, if needed, and to obtain a familiarity with your skin so that he or she can identify skin changes in the future. Wear sunscreen :)
