Proton Therapy for Sarcoma
Proton therapy is an advanced treatment that delivers radiation to the exact size, shape and depth of your tumor. It lets your physician treat your cancer while helping to protect nearby tissue. This makes proton therapy a good option for treating tumors near healthy organs, including sarcomas.

When Is Proton Therapy an Option?
Patients with sarcoma may have a wide range of treatment options, based on the type, location and stage of the cancer. Usually, treatment options include proton therapy, standard X-ray radiation therapy, surgery, chemotherapy, cryotherapy and radiofrequency ablation.
Proton therapy is an important option, especially if:
- Your tumor is in your abdomen or close to vital organs.
- You are trying to preserve certain functions, like your fertility.
- You have had radiation therapy before.
- Your cancer has come back after treatment (possibly in a different part of your body than your original tumor).
Compared to standard radiation therapy, proton radiation therapy can be better at sparing healthy tissue near the tumor from the harmful effects of radiation. This matters most if you are likely to need treatment several times over many years.
Treatment that removes or destroys all or part of a cancer; can also be used to remove or stop the function of an organ. For example, removing the ovaries or testicles or taking medicines that cause them to stop making their hormones would be called ablation. Besides surgery and drug treatment, other ways of ablating body tissues and tumors include extreme heat, freezing and chemicals.
