The Clackamas Radiation Oncology Center Team

Radiation oncologist

Radiation oncologists are doctors who specialize in using radiation to treat cancer. Your radiation oncologist will oversee your radiation therapy, working with other members of your radiation therapy team to develop your treatment plan and make sure that each treatment is given accurately. He or she also will track your progress and will adjust your treatment as necessary to make sure you receive the best care with minimal side effects.


Dosimetrists work with the radiation oncologist and a medical physicist to carefully calculate the dose of radiation to make sure the tumor gets enough radiation. Using computers, they develop a treatment plan that can best destroy the tumor while sparing the healthy tissue.

Medical physicist

Medical physicists work directly with the radiation oncologist during treatment planning and delivery. They oversee the work of the dosimetrist and help ensure that complex treatments are properly tailored for each patient. Medical physicists also direct quality control programs for equipment and procedures, ensuring maximum safety and effectiveness.

Radiation therapists

Radiation therapists work with radiation oncologists to give the daily radiation treatment under the doctor's prescription and supervision. They maintain daily records and regularly check the treatment machines to make sure they are working properly.

Radiation oncology nurses and medical assistants

Radiation oncology nurses and medical assistants work with every member of the treatment team to care for you and your family before, during and after treatment. They will explain the possible side effects you may experience and will describe how you can manage them. They will assess how you are doing throughout treatment and will help you cope with the changes you are experiencing.

Social workers and oncology patient advocates

Social workers and oncology patient advocates offer a variety of support services to you and your family. They can provide counseling to help you and your family cope with the diagnosis of cancer and with your treatment. They may also help arrange for home health care and other services.


Nutritionists, also called dietitians, can help you maintain your weight during treatment. They will help you modify your eating plan if the side effects of treatment are affecting your appetite; will determine what you can eat; and can provide recipes, menu suggestions, and information on ready-to-use nutritional supplements.
