How does radiation therapy work?
Radiation therapy uses targeted energy (e.g., X-rays, radioactive substances) to destroy cancer cells, shrink tumors, and/or alleviate certain cancer-related symptoms. It may be used:
- As a primary treatment to destroy cancer cells
- In combination with other treatments to stop the growth of cancer cells
- Before another treatment to shrink a tumor
- After another treatment to stop the growth of any remaining cancer cells
- To relieve symptoms of advanced cancer
Radiation therapy is an important part of treatment for many of our patients. Because each cancer type requires a different approach, each patient’s treatment plan is customized to their unique needs and treatment goals.
Imaging techniques allow radiation oncologists to closely track tumors, before and during radiation treatment. We use highly targeted radiation technologies to deliver maximum radiation doses to tumors, with less impact on healthy tissues and organs. We often can provide options to patients who have reached their maximum tolerated dosage of traditional radiation.
Radiation therapy may be given alone or in combination with other treatments, such as surgery, chemotherapy, hormone therapy and/or immunotherapy. Throughout treatment, radiation oncologists monitor the effectiveness of the radiation therapy and modify treatment plans accordingly.
Common side effects of radiation therapy
Treatment with radiation therapy may cause certain side effects, including:
- Skin reactions
- Fatigue
- Lymphedema
Our options
Radiation therapy can be delivered externally or internally. The type of radiation therapy a patient receives may depend on a variety of factors, such as the type of cancer and the size and location of the tumor(s) to be treated. Radiation therapy delivery methods we use include:
