Types of doctors who treat cancer

Doctors who specialize in treating cancers are known as oncologists. Oncologists are familiar with the characteristics of different cancers, and will have an opinion on how best to treat each cancer. Oncologists will be familiar with the different ways to treat cancers, including surgery, chemotherapy, radiotherapy and immunotherapy. However, most oncologists are internal medicine specialists and do not operate on patients. If surgery is required, the oncologist may refer the patient to either a surgeon, or a surgical oncologist (a surgeon who specializes in tumor removal).

Surgeons often specialize in operating on specific organs. Some surgeons specialize in operations of the lung, others on the colon and so on. It is thought that surgeons who repeatedly operate on the same organ become much better at it, so specialization does improve the outcome for patients. Surgeons refer to the process of removing tumors as a "resection", so removing a tumor from a lung may be referred to as performing a lung resection.

If radiotherapy is required, a patient may be referred to a radiation oncologist. Radiation oncologists specialize in using radiation to treat cancer. Because modern radiotherapies are becoming increasingly complicated, radiation oncologists are a specialization that is becoming increasingly important. Radiation oncologists will be familiar with the different radiation therapies available, and how best to deliver radiation while causing the least side effects.

Patients may also encounter diagnostic radiologists if they undergo diagnostic imaging procedures such as a CT scan or an MRI scan. It is a common misconception that such scanning technologies produce "clear and unambiguous" diagnoses of cancer. In reality, such scanning technologies produce thousands of images which a doctor familiar with scanning technologies (i.e. the diagnostic radiologist) needs to interpret. They need to determine if spots or gray areas that appear in scans are tumors, or other normal body artifacts like cysts, or if they are just normal for that particular scanning technology. Much of this interpretation is a judgment call, and good diagnostic radiologists will be instrumental in monitoring cancers.

Patients undergoing chemotherapy or radiotherapy may also be referred to a nutritionist. During cancer treatment, it is important for the patient to maintain a healthy diet so that the body can function properly. Some chemotherapies can damage the body and weaken it, so it is important that the body continue to receive good nutrition. Chemotherapy can also make it difficult for patients to swallow food because of mouth ulcers and dry throats. A nutritionist may be able to suggest easier to swallow foods, like fruit smoothies, which can provide the needed nutrition. Nutritionists may also recommend multivitamins or other supplements to keep a healthy body. During cancer treatment it is also important that the patient maintain a healthy weight, and not succumb to cachexia (the wasting away of the muscles and becoming very thin). Nutritionists can also suggest diets to help minimize this risk.

Oncology nurses also play an integral role in patient care. They often have practical know-how to make patients more comfortable during their treatment. They can also provide useful tips to caring for the patient, and tell caregivers what problems to watch out for.
