Cancer care is provided by specialists who focus on diagnosing and treating it. The professional who treats cancer is an oncologist. They oversee and coordinate cancer treatment, which may include chemotherapy, targeted therapies, immunotherapy, hormone therapy, and sometimes work with surgeons or radiation oncologists for combined approaches. They also monitor how the cancer responds and adjust plans as needed. The other choices don’t treat cancer directly: ophthalmologists care for the eyes, orthodontists correct teeth alignment, and pathologists examine tissue samples to diagnose diseases (including confirming cancer) but do not typically provide treatment.
