Can a dermatologist tell if a mole is melanoma?
They will ask you questions about how long you've had it, and what changes you have noticed. Doctors can look very closely at the skin with an instrument called a dermatoscope. This is to check for signs of melanoma or non melanoma skin cancer. They will also check the rest of your skin for any changes.

How does amelanotic melanoma start?
Amelanotic melanoma begins when these skin cells grow out of control. Amelanotic melanoma cells are unable to produce more pigment, so the actual amelanotic melanoma lacks pigment, or color. The cause of the melanocyte cells that lead to amelanotic melanoma is not known. Many scientists believe that it is genetic.
