What is the name of Wilson’s specialty in House M.D.?

James Wilson’s medical specialty in House M.D. is oncology.

Wilson, played by Robert Sean Leonard, is the head of the Department of Oncology at Princeton-Plainsboro Teaching Hospital. He treats patients with cancer and often provides House with a more empathetic perspective on difficult ethical and personal decisions.

The friendship between Wilson and House is one of the show’s most important continuing relationships. Wilson is generally warmer and more socially responsible than House, but he repeatedly remains involved in House’s life despite their conflicts.

Oncology is the branch of medicine concerned with cancer, including its diagnosis, treatment, and follow-up care. Viewers may confuse Wilson’s specialty with neurology because House’s diagnostic department handles many cases involving the nervous system. Wilson, however, is specifically the hospital’s oncology leader.
