What is an Oncologist and How Can They Help You?

  • Specializes in neoplastic processes throughout the body
  • Conducts cancer evaluations, orders diagnostic and staging studies, establishes cancer stages, formulates treatment strategies
  • Manages breast malignancies, pulmonary cancers, colorectal tumors, hematologic malignancies, lymphoproliferative disorders, and various solid neoplasms
