Yes it sure is a worry getting skin cancer.
I had a nasty one on the side of my face, but having a fear of needles and going under the knife I fixed it a different way.
Someone put me onto "black salve" and after 1 applications it completely disappeared.
Its amazing stuff and you can put it anywhere on the skin and it will destroy only the cancer cells.
An Ausie doctor invented another cream made from egg plant extract, but the govt banned it here. Apparently you can get it from overseas.
If you want to get the black salve, I would be quick because they are trying to ban this as well.
Do a lot of research yourself first if you want to try something like this, but I am living proof it kills skin cancer and removes any cancerous moles. For me it took 4 days and it fell off my face and completely healed up in 8 days.
