The nose is a shelf of skin that sticks out into the sun all of your life so unfortunately is a very common site for skin cancers.

It is also a cosmetically very obvious site.
Unfortunately there is very little lax skin on the lower part of the nose which makes it hard to close holes in the skin once a skin cancer has been cut out.
Skin grafts or flaps are usually required except for the smallest lesions.
Thus the earlier and smaller cancers on the nose are detected the better.
