Mole growing in size and changing colour. Should I be worried? (photos)

Anytime a mole is growing or changing, I suggest it should be evaluated in person by a dermatologist. The ABCDEs need to be used when examining your skin, and in this case, 2 of the 5 are happening, so you need to make an appointment to have it checked properly. "This answer has been solicited without seeing this patient and cannot
be held as true medical advice, but only opinion. Seek in-person
treatment with a trained medical professional for appropriate care."

Any time a mole is changing, to be safe, you should be carefully evaluated by a
board certified dermatologist. Please use the ABCDE's as your guide for
when to be concerned about moles: A for Asymmetry; B for
Irregular Borders; C for
Black or uneven Colors; D for diameter greater than a pencil eraser; and E for
a growth that is Evolving or changing. If necessary, it is an
extremely simple five minute procedure for a dermatologist to remove the mole
using either a "punch" or a "shave" biopsy which typically
leaves a minimal scar. The mole can then be checked microscopically for
reassurance. Your photo indicates there is some asymmetry and with your family history of melanoma and your fair complexion you may have an increased risk. So you should definitely have this mole checked.You can follow the video link to learn more about identifying the
