could it be skin cancer?

Twice a year I would suffer from really dry skin on my hands.  Once at the beginning of winter and once at the end.  It would stick around for a couple of weeks and then clear up.  Just a couple of months ago I got a red patch of skin on the top inside of my wrists that didn't go away.  It didn't itch or hurt.  Since then I have developed several more spots.  Three on my right wrist and one on my left.  They are a much darker red and look more like scarish and a little scabby.  They do not hurt or itch eaither and cream seems to have no affect on them at all.  There is also a very small spot on one finger on each hand, these seem to clear up maybe for a day or two then return.  I have look up both excema/psoriasis and Basal Cell.  It definitely does not, at least to me, look anything like excema/psoriasis, especially since it is not very wide spread.  It does look a lot more like pictures of superficial Basal Cell but I wasn't sure if Basal Cell acted like this.  Do you usually only get one spot with Basal Cell or can there be more.  Do you think I should get it checked or have nothing to worry about.

I also have to add that when I would get the reall dry skin it would itch like crazy and hurt a little until it cleared up, which is normal for dry skin.
