Hi, I am a 37 yr old woman, fairly healthy, but am a smoker (I have been trying to quit but am having difficulty being in nursing school). I lived at the beach my whole life, and was definitely not careful about sunscreen. I have moved to AZ and developed a photosensitivity (I get bumps and pruritis every time I go in the sun for too long), and I have had this happen about 10 times in the past year. Anyway, I noticed this tiny black mark on my face a week or two ago. I tried to pcik it, thinking it was a big blackhead. It's black and a little bigger than a pencil point. It's too small to tell if it has irregular borders, but I don't think it does, and it's not raised. Could this be cancer? My mom died from lung cancer last year, and I am terrified. Also, if I quit smoking this summer, is it still early enough to possible\y save me from cancer (I have smoked a pack a day for 20 yrs). Any advive would be appreciated.
