I have a mole when i bump it is sore, and bled when i bumped it yesterday, the skin is red around the edges like it's irritated. does this mean cancer?

It could just mean: an irritated mole, a cyst under the mole, or of course small chance it could be abnormal. See dermatologist for diagnosis and treatment options

Needs biopsy: An enlarging or changing mole should be addressed by excisional biopsy. See your dermatologist or plastic surgeon to have it addressed. The obvious concern is a change or dysplasia in a mole which can lead to melanoma.
