The Young Doctors (1961)

When young Dr. David Coleman (Ben Gazzara) arrives at a large New York hospital to join the pathology staff, he is greeted with hostility by aging chief pathologist Dr. Joseph Pearson (Fredric March), who regards Coleman's arrival as a personal criticism of his competence. The two men first clash when David demands that three separate blood tests be made to determine whether an expectant mother's blood has become sensitized. Irritated by the young man's superior attitude, Pearson refuses to order the serum necessary for the third test. As the days pass, David becomes emotionally involved with Cathy Hunt, a student nurse troubled by a knee tumor. To determine whether the condition is cancerous, Pearson orders a biopsy.
