I don't think it's skin cancer, don't worry, honey!
Have you been using a different body lotion or cream on these particular areas of your body lately? If so, try staying off it for a short while and if it stops, then you are very likely to be allergic to this particular body cream.
If it doesn't go away, then you are allergic to something else, so get that checked out.
Also, if you've been having the central heating on seeing as it's so cold at the moment, it might be making you skin dry and flaky.
Best of luck!
I really hope it clears up soon!
