What is radiation therapy?
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
At Cancer Treatment Centers of America® (CTCA), our radiation oncologists are experienced in using advanced technologies to deliver targeted radiation therapy while also proactively managing side effects.

Types of radiation
Some radiation therapy delivery methods include:
- External beam radiation therapy – radiation is directed from a machine outside the body onto cancerous cells within the body. (Examples: 3D conformal radiation therapy, IMRT, IGRT, TomoTherapy, stereotactic radiosurgery)
- Internal radiation therapy – radioactive material is placed (via a catheter or other carrier) directly into or near a tumor. (Example: high-dose rate brachytherapy)
- Systemic radiation therapy – a radioactive substance (that is swallowed or injected) travels through the blood to locate and destroy cancerous cells. (Example: radioactive iodine therapy)
Experienced care team
Our radiation oncologists specialize in delivering maximum radiation doses to tumors with less damage to healthy tissues and organs. Our radiation oncologists will work closely with you and the rest of your care team to deliver radiation therapy based on your individual needs.
Individualized treatment approach
Radiation therapy is an important part of treatment for many of our patients. Since each cancer type requires a different approach, your treatment plan will be based on your unique needs and treatment goals.
Our radiation oncologists use advanced imaging techniques before and during radiation treatment so we can closely track the tumor. We use highly targeted radiation technologies to deliver maximum radiation doses to tumors, with less impact on healthy tissues and organs. Thereby, we can often provide options to patients who have reached their maximum tolerated dosage of traditional radiation.
Depending on your individual needs, you may receive radiation therapy alone or in combination with other treatment modalities like surgery, chemotherapy, hormone therapy and/or immunotherapy. Throughout your treatment, your radiation oncologist will monitor the effectiveness of the radiation therapy and modify your treatment plan accordingly.
Managing radiation side effects
Typical radiation therapy can be damaging to the body and cause unpleasant side effects, such as skin changes, fatigue, nausea, and other side effects, depending on the part of your body being treated. During your radiation treatment, clinicians from a variety of integrative oncology services will work with you to reduce side effects and improve your quality of life.
Radiation therapy for soft tissue sarcoma
Depending on the type of soft tissue sarcoma you have and the extent of the disease, your soft tissue sarcoma treatment plan at CTCA may include radiation therapy.
Though surgery is usually the main treatment approach for soft tissue sarcoma, radiation treatments may also be used before (neoadjuvant therapy) or following surgery (adjuvant therapy).
Advanced radiation treatment for soft tissue sarcoma
Soft tissue sarcomas are very rare, and there are more than 50 different types that can be diagnosed. They can also be surrounded by sensitive tissues like nerves and blood vessels, or be located near vital organs such as the lungs or heart.
At CTCA, we have radiation oncologists and other experts who have experience in dealing with advanced and complex cases of soft tissue sarcoma. These radiation oncologists work side by side with our surgical oncologists, medical oncologists and other clinicians and specialists to help plan, coordinate and deliver radiation therapy.
We also use advanced treatments and high-tech radiation delivery methods to maximize the effect of soft tissue sarcoma radiation therapy, while minimizing side effects caused by damage to surrounding healthy tissues.
