What is this?

Its on my left cheek for 2 years, its often scabbing and sometimes whitehead forms inside. I popped it like 12 times in last two years. Doctor thinks its some aterum deep cyst or basal skin cancer but isnt sure either, because its not really growing he recommend to watch it and take pictures for next 4 weeks.. that surgery and cutting it off isnt neccesary yet... but i guess i will need to cut it one day anyway no? Its not gonna go away after 2 years...

Its kinda small like 1.5mm? Any help would be very welcomed because i dont really want 2 stitches on my cheek :(
