Nose cancer

Ive this burning mark on my nose. Ive been 3 times to the doc it gets large every summer in the sun the size of a pencil eraser. Doc sent me to a specialist and he looked at it for 3 seconds and said it is an overactiv oil gland but it was winter when the appointment finally came and had shrunk tiny. Its a burning feeling and is annoying a girl i know from the same village had one and lost half her face due to it. I dont trust the specialists opinion
