Rowena,

I had a brown, odd shaped mole for years, maybe all my life, on my temple. It 
started turning black on one side, and it bled once. They say that's not good. 
I dissolved baking soda in a tsp of water and added a tsp of dmso to it. I 
applied it to the mole and after a couple weeks it turned brown again, and in 
another couple weeks I couldn't even see where the mole had been.

Don't know if it was cancer, but its gone now, so it doesn't matter.

Give it a try.
