Many types of physicians treat skin cancers today, e.g., plastic surgeons, dermatologists, ear, nose and throat surgeons, general surgeons, family practitioners and internists. Many studies have shown that the correct diagnoses and treatments for skin cancer are most frequently delivered by dermatologists who study skin cancer constantly for three years during their training. Plastic surgeons train in their final field of chosen study/profession for just two years after 5 years of general (bowel, gallbladder, abscess, etc.) general surgery training. Dermatologic surgeons, however, may train for between four and five years in their final field of chosen study/profession.  There are good and bad doctors in all specialties; much time should be spent in research before a patient chooses a skin-cancer specialist.
