Is it normal that I have a fading mole on my ear cartilage?

This does not sound too sinister, altough any changes to a mole warrant getting it looked at.  There is no substitute for a clinical examination, so if it has bothered you enough to post this question on this site, then I would say that it is worth visiting your local doctor for a face to face opinion.

Good luck.

Yes, it can be normal for a mole to fade and it actually is more common than we think. Often it is a sign that the mole is being reabsorbed by your body. Classical warning signs of skin cancer are darkening, not lightening, of the mole. Of course, nothing is ever 100% certain so there is no substitute for a physical examination by a dermatologist and skin biopsy, if indicated. If necessary, a mole on the ear can be easily removed by a "shave biopsy" and sent to the lab for microscopic examination.
