I had a big lump on my leg and it doesn't itch and it feels really hard! This is what it looks like http://oi46.tinypic.com/2rc49js.jpg help me please! Its been there over 2 weeks now! Could it possible be cancer? I know its not a pimple or white head!

Your picture isn't showing.
I doubt that a bump on a leg is cancer. There are countless benign lumps, but see a dermatologist.
