Could it be Skin Cancer?

I have recently spent a lot of time in the sun without wearing sunblock. A couple days ago I found two small, beauty-mark looking things on my shoulder and stomach. Could these possibly be cancerous? I would like to hear from people with personal experience or medical knowledge.

Cancer will not "pop up" after a lot of sun exposure. I would suggest you wear the sunblock of course, and just keep an eye on the spots. They are probably freckles that came out when you exposed the skin to the sun and will probably go away in a few weeks. Source(s): retired nurse

probably not

it's impossible to diagnose something so visual as a skin tumor without seeing it and through the limited information you gave

also, do yourself a favor and wear sun screen. rates of melanoma are reaching record highs, and at the very least, the sun destroys your skin.

by the time you're 20, too much sun exposure can make your skin look 40, by the time you're 30, it'll look 60. Keratoses, liver spots, and all sorts of blemishes can develop too, so just do yourself a favor and wear it.
I have had similiar things checked on my body. What you should look for: A. asymmetrical
B. irregular border
C. Variably or different colors
D. Large diameter
E. Slightly raised or elevated.
These could all be risk factors for melenoma especially if it runs in your family and you have had a couple of sun burns. There is a website you can check out www.aad.org. If you have any other questions see a dermatolgist.
Freckles? Seborrheic dermatoses? It was not a smart thing to do, but skin cancer does not develop that fast due to sun exposure.
Go to your healthcare provider for him/her to check them out.
