My son has a pimple size bump on the back of his hand. It doesn't look like a wart . Could it be skin cancer

We used Compound W which did nothing. How could we tell if it is just a new mole or something more serious?|||I have answered a question about the skin symptoms:


Some symptoms of skin cancer may include the following :





Enlargement of an existing skin lesion.


Reddish patch or irritated area, frequently occurring on the chest, shoulders, arms, or legs.


Poorly defined borders of a skin lesion.


Itching.


Ulceration or bleeding of an existing mole.|||It could be a small cyst. They are not really dangerous. You need to have his doctor look at it no mater what it is if it does not go away in a day or two.
