Proton Beam Therapy
A prostate cancer diagnosis often brings many questions, especially when you begin learning about different treatment options. If you’ve heard about proton beam therapy in Chicago, you may be wondering how it works, whether it’s right for you, and how it compares to other treatments.
Proton beam therapy is a type of external beam radiation therapy that uses positively charged particles called protons to treat cancer. Like other forms of radiation therapy, its goal is to destroy cancer cells while preserving as much healthy tissue as possible.
Unlike traditional radiation therapy, which uses X-rays (photons), proton therapy delivers energy that can be more precisely targeted to the treatment area. This precision may reduce the amount of radiation delivered to nearby healthy tissues, including the bladder and rectum, which are located close to the prostate.
For many men with localized prostate cancer, proton therapy is one of several effective treatment options. It is most commonly considered for prostate cancer that has not spread beyond the prostate, although every treatment plan is based on the individual’s diagnosis and overall health.
How Proton Beam Therapy Works
Before treatment begins, your radiation oncology team develops a personalized treatment plan. Imaging studies such as CT scans and MRI scans help identify the exact location of the prostate and surrounding structures.
Some patients may have tiny markers, called fiducial markers, placed in the prostate before treatment. These markers help guide each treatment session, so the radiation is delivered as accurately as possible. Your physician may also recommend a temporary hydrogel spacer between the prostate and rectum to reduce radiation exposure to nearby tissue.
During treatment, you lie on a treatment table while the proton therapy machine delivers carefully planned beams of radiation from different angles. The treatment itself is painless. Most appointments take about 15 to 30 minutes, although the actual delivery of radiation typically lasts only a few minutes.
Many treatment schedules involve sessions five days a week for several weeks, although shorter treatment schedules may be appropriate for some patients. Your care team will recommend a schedule based on your diagnosis and treatment goals.
Most people continue many of their normal daily activities throughout treatment.
Possible Side Effects
Like all forms of radiation therapy, proton beam therapy can cause side effects. Because the treatment is more targeted, the hope is that side effects are more mild than traditional radiation.
Still, the type and severity of side effects vary from person to person.
Some men experience temporary urinary symptoms, such as increased frequency, urgency, or mild discomfort during urination. Others may notice bowel changes, including loose stools or mild rectal irritation. Fatigue may also develop gradually during treatment.
Many of these side effects improve after treatment ends, and your healthcare team can recommend strategies or medications to help manage them.
Discussing possible short-term and long-term side effects with your radiation oncologist can help you understand what to expect based on your individual situation.
Choosing the Right Treatment for You
One of the first things many men ask after diagnosis is, “Which treatment is best?”
The answer depends on many factors. Your physician may consider:
- Your PSA level
- Your Gleason grade Group and cancer stage
- Whether the cancer is confined to the prostate
- Your age and overall health
- Existing urinary or bowel symptoms
- Your lifestyle and personal preferences
For some men, active surveillance may be appropriate. Others may benefit from surgery, radiation therapy, brachytherapy, hormone therapy, or a combination of treatments.
Rather than focusing on a single treatment, it’s helpful to understand all of your options before making a decision. The Prostate Cancer Foundation of Chicago (PCFC) encourages patients to compare different treatment options and learn more about available prostate cancer treatments before selecting an approach with their healthcare team.
