Oncology
Overview
Medical oncology is the diagnosis and management of benign and malignant neoplasms. The
general internist should have a wide range of competencies in the evaluation and management of
neoplastic disease. He or she must be able to 1) identify patients at risk for malignancy and
counsel them regarding risk reduction and screening; 2) investigate clinical syndromes
suggestive of underlying malignancy; 3) undertake the palliative care of patients with common
solid and hematologic tumors; 4) identify neoplasms with a potential for cure and direct affected
patients to the appropriate centers or providers; and 5) participate in the difficult decisions
regarding all aspects of management, including diagnostic evaluation and screening, treatment
and palliative care. In addition, the general internist must be familiar with the administration,
side effects and drug interactions of therapeutic agents commonly used for the treatment of
malignant disease.
Whether a generalist assumes full responsibility for any or all of these functions will depend on
the clinical setting of his or her practice. The general internist should seek subspecialty
consultation early in the care of patients with malignant disease who may be candidates for
aggressive treatment with curative intent.
