Been there, done that. Had a basil cell carcinoma removed from my chest, a number of moles and "age spots" as well as actinic keratoses frozen off, one of which the dermatologist said "I think we got it, but if it ever comes back, I want to see you immediately."
While melanoma is really aggressive, hardly anyone ever dies from basil or squamous cell cancers -- unless they ignore them for way too long. Those of us getting up in years need to be proactive about this. Get your hide checked by a dermatologist. The life you save could be your own.
