Through a combination of physical examinations, medical history reviews, and diagnostic tests, oncology doctors determine if a patient has cancer, its stage, and whether it has spread to other parts of the body.

Based on the diagnosis, oncology doctors develop personalized treatment plans for each patient. They consider various factors, including the type of cancer, its stage, the patient’s overall health, and their treatment preferences. Oncology doctors discuss treatment options with patients, explaining the potential benefits, risks, and side effects associated with each choice.

By working together, these healthcare professionals bring their collective expertise to the table, enhancing the overall quality of care.

This coordination helps streamline treatment plans, minimize delays, and provide patients with a seamless experience throughout their cancer journey.
