Yes, UV rays play the leading role. Read this:I wonder what the difference is? Something to do with the UV damaging DNA? I've skinned my knees from sports a few dozen times. I always wondered.
Too much UV radiation from the sun or sunbeds can damage the genetic material (the DNA) in your skin cells. If enough DNA damage builds up over time, it can cause cells to start growing out of control, which can lead to skin cancer.
It's more a theoretical difference. Whenever cells multiply in large orders, chances are that there will be damaged ones among them and a few could be cancerous. Plus that carcinogens could enter the body via a wound.I wonder what the difference is?
This is not straight forward, "injury" in the sense of physical trauma (besides UV damage which has been mentioned) I would have thought not so much.Just curious.
Based on studies I’ve read, I am assuming this because the cells have to divide to recover from wounds/injuries. Therefore, DNA has to be replicated and there’s a chance of a cancer-causing mutation to occur.
Would this be right?
This paper has been discussed previously in PF. See the following thread and my insight post for more discussion:A CNN article is no scientific source. However, they often cite the paper where they have their information from. It's necessary to read this before one jumps to conclusions. "Bad luck" is one thing, caused by an injury a completely different one.
