Men who are considering radiotherapy may want to discuss Proton Beam Therapy as an option.
What to Expect
PBT is similar to other forms of radiotherapy. The patient will have advanced imaging via MRI or CT Scan to help pinpoint the location of the tumor. During therapy, the practitioner positions the patient and a machine directs a beam of radiation into the cancer. The treatment is quick and non-invasive. Patients can typically return to daily activities immediately.
Who orders or performs the treatment?
What are common side effects?
Like other forms of radiotherapy, PBT has a risk of urinary and sexual side effects. However, side effects are potentially less severe since the beam is concentrated on the cancerous cells.
