F

at your age. CT resolution is not that good compared with size of heart arteries; the arteries never stop moving, thus can only see large enough accumulations of calcium. At microscopic scale, calcium at base of plaques can been seen in 10 yr olds, but is rarely seen on best CT scans until mid-30s.

Plaque is an accumulation of WBCs, not calcium. CT can't distinguish WBCs or clots in artery lumens.   

Please have this checked by a doctor. This type of thing needs to be examined to be sure.

At your age, skin cancer is not likely, but not unheard of. Better to be safe and get that checked out.   

This may very we be a swollen benign lymph node associated with a resolving infection because it is getting smaller. Please get it checked by a doctor because this is something that needs to be examined and sometimes even biopsied to be sure what is going on.

  

This is something that must be seen and possibly even biopsied to diagnose.
