Is this any type of skin cancer? (Photo)

I have this mole on my right leg for more than 6 months it started itching and the color changed in the 1-2 month but now it stays the same. It itches like crazy when I mess with it. It doesn't hurt at all but when I mess with it the surrounding itches too. After scratching for a while it will stop. No pain at all, it feel great actually. It has been like that for the last 3-6 months. I went to a doctor to see what it is, but he said it was just a bug bite or ingrown hair. Please help!
