Suddenly i have got this big type of mole at the edge of my right hand..im worried about this..please suggest?

See a dermatologist: If you notice a new mole or a changing mole, it should be evaluated by a dermatologist. Asymmetry of the mole, uneven borders, multiple colors, larger than a 1/4 inch in diameter, or the mole evolving are a few of the cardinal signs of potential melanoma. The dermatologist will decide once seeing it if it needs to be biopsied.

See your derm: Any new skin lesion should be brought to the attention of your friendly dermatologist.
