Ask A Skin Doctor: Back Mole

Dear Doctor

I had first seen this growth on my brother’s back a few months ago and have now noted a slight change in the size and the shape of its border.

I’m quite concerned about the possibility of cancer and would very much appreciate an opinion. Thank you very much!

back mole

Dear Patient

This mole has several signs associated with malignant melanomas. These signs are:

A Asymmetrical shape since one half of the lesion does not match the other half.

B Border irregularity since its border is notched or scalloped.

C Color variation since it has different shades of black.

E  Evolving since it is changing in size and shape.

The only sign I cannot speak about is the D for diameter but you can measure it at home and if it is more than 6 mm or 1¼ inch, that is another danger sign.

You therefore need to advise your brother to visit a dermatologist so that they can remove it for examination under a microscope in the lab.
