Prostate Cancer Radiation Therapy
Radiation therapy is a commonly used treatment approach for prostate cancer. It involves the use of high-energy radiation to target and destroy cancer cells in the prostate gland. Prostate cancer radiation therapy can be an effective treatment option, either as the primary treatment or in combination with other therapies. Understanding the fundamentals of this treatment is crucial for individuals diagnosed with prostate cancer.
Understanding Prostate Cancer Radiation Therapy
Prostate cancer radiation therapy, also known as radiotherapy, utilizes targeted radiation to kill cancer cells and shrink tumors in the prostate gland. It works by damaging the DNA of cancer cells, preventing them from multiplying and causing further harm. The goal of this therapy is to eliminate or control the growth of cancer cells while minimizing damage to healthy surrounding tissues.
Radiation therapy can be administered using different techniques and technologies. The choice of treatment depends on various factors, including the stage of the cancer, the size and location of the tumor, as well as the patient’s overall health and preferences.
Types of Radiation Therapy for Prostate Cancer
There are three primary types of radiation therapy commonly used for prostate cancer: external beam radiation therapy, brachytherapy, and proton therapy.
External Beam Radiation Therapy: This technique involves directing radiation beams from an external machine to the prostate gland. These beams are precisely targeted at the tumor site to deliver high doses of radiation while minimizing exposure to surrounding healthy tissues. External beam radiation therapy is typically administered over several sessions, known as fractions, to ensure the effectiveness of the treatment. For more information on how external beam radiation therapy works and the associated side effects and risks, refer to our article on external beam radiation therapy.
Brachytherapy: Brachytherapy, also known as internal radiation therapy, involves the placement of radioactive implants, known as seeds, directly into the prostate gland. These seeds emit radiation that targets the tumor from within. Brachytherapy can be performed as a permanent implant or a temporary procedure, depending on the specific treatment plan.

Proton Therapy: Proton therapy is a highly precise form of radiation therapy that utilizes protons to target cancer cells. Unlike traditional radiation therapy, which uses X-rays or photons, proton therapy delivers radiation with minimal damage to surrounding tissues. This makes it especially beneficial for treating prostate cancer, as it reduces the risk of long-term side effects. To gain a deeper understanding of how proton therapy works and the associated side effects and risks, refer to our article on proton therapy.
By exploring the different types of radiation therapy available for prostate cancer treatment, individuals can make informed decisions alongside their healthcare providers. It’s important to consider factors such as cancer stage, treatment goals, and personal preferences when determining the most suitable approach.

External Beam Radiation Therapy
External beam radiation therapy is a common treatment approach for prostate cancer. This type of radiation therapy uses high-energy beams to target and destroy cancer cells within the prostate gland. Let’s explore how external beam radiation therapy works and the potential side effects and risks associated with this treatment.
How External Beam Radiation Therapy Works
External beam radiation therapy involves the use of a machine called a linear accelerator. This machine delivers radiation beams from outside the body to the prostate gland. Before the treatment begins, the radiation oncologist carefully plans the radiation delivery using imaging techniques, such as CT scans, to precisely target the tumor while minimizing exposure to healthy tissues.
During each treatment session, the patient lies on a treatment table while the linear accelerator directs the radiation beams towards the prostate gland. The treatment is typically painless and is usually administered on an outpatient basis. The entire course of external beam radiation therapy typically spans several weeks, with multiple treatment sessions scheduled over that period.
Side Effects and Risks
While external beam radiation therapy is effective in targeting and destroying cancer cells, it can also affect nearby healthy tissues, leading to some side effects. The severity of side effects varies from person to person and depends on several factors, including the total dose of radiation, the treatment area, and individual patient characteristics.
Common side effects of external beam radiation therapy for prostate cancer may include:
- Fatigue: Many patients experience fatigue during their treatment course. This can range from mild to severe and tends to improve after the treatment is completed.
- Urinary Problems: Radiation therapy can cause urinary side effects, including increased frequency, urgency, and discomfort during urination. These symptoms usually subside gradually after treatment.
- Bowel Problems: Some patients may experience bowel changes, such as diarrhea, rectal bleeding, or discomfort. These symptoms are usually temporary and improve over time.
- Erectile Dysfunction: Radiation therapy can also lead to erectile dysfunction in some patients. This side effect may develop gradually after treatment and can be managed with appropriate interventions.
It’s important for patients to discuss potential side effects and risks with their healthcare team before starting external beam radiation therapy. Healthcare professionals can provide personalized guidance and support to help manage these side effects effectively.

Understanding the benefits and potential risks of external beam radiation therapy is essential for making informed decisions about prostate cancer treatment. With advancements in radiation therapy techniques, side effects can often be effectively managed, allowing patients to receive optimal cancer treatment while maintaining a good quality of life.
Brachytherapy
Brachytherapy is a form of radiation therapy commonly used to treat prostate cancer. It involves the placement of radioactive sources directly into or near the tumor, delivering targeted radiation to the affected area. This section will explore how brachytherapy works, as well as its potential side effects and risks.
How Brachytherapy Works
Brachytherapy utilizes small radioactive seeds or pellets that are inserted into the prostate gland. These seeds emit radiation that kills cancer cells and shrinks tumors over time. The procedure is typically performed under anesthesia and can be done in two ways: permanent and temporary brachytherapy.
Permanent Brachytherapy
In permanent brachytherapy, small radioactive seeds about the size of a grain of rice are placed inside the prostate. These seeds remain in the prostate permanently, slowly releasing radiation over several months. Over time, the radiation diminishes, and the seeds become inactive. They remain in the prostate without causing any harm.
Temporary Brachytherapy
Temporary brachytherapy involves the temporary placement of radioactive sources into or near the prostate for a specific period of time. This can be achieved through the use of catheters or applicators. The radiation sources are then removed after the desired treatment duration. Temporary brachytherapy may be delivered in high-dose rate (HDR) or low-dose rate (LDR) forms, depending on the treatment plan.
Both permanent and temporary brachytherapy aim to eradicate cancer cells while minimizing damage to surrounding healthy tissue. The choice between the two methods depends on various factors, including the stage and aggressiveness of the cancer, as well as the patient’s overall health.
Side Effects and Risks
Like any cancer treatment, brachytherapy for prostate cancer can have side effects and risks. It’s important for patients to be aware of these potential effects before undergoing the procedure.
Short-term Side Effects
Short-term side effects of brachytherapy may include:
- Urinary Symptoms: Patients may experience increased urinary frequency, urgency, or discomfort during urination. These symptoms usually improve over time as the prostate heals.
- Bowel Symptoms: Some individuals may experience temporary bowel changes, such as diarrhea or rectal bleeding. These symptoms tend to resolve as the body adjusts.
- Erectile Dysfunction: Brachytherapy can potentially lead to erectile dysfunction, although the risk is generally lower compared to other treatment options like prostate cancer surgery.
Long-term Side Effects
Long-term side effects of brachytherapy can include:
- Urinary Incontinence: In rare cases, patients may experience long-term urinary incontinence, which can range from mild to more significant.
- Erectile Dysfunction: While the risk of erectile dysfunction is generally lower with brachytherapy, it can still occur in some cases.
Your healthcare provider will discuss the potential side effects and risks with you in detail before proceeding with brachytherapy. They will also provide guidance on managing any side effects that may arise during or after the treatment.
Brachytherapy is just one of the radiation therapy options available for prostate cancer. Other forms of radiation therapy, such as external beam radiation therapy and proton therapy, may be considered based on individual cases. It’s important to consult with your healthcare provider to determine the most appropriate treatment approach for your specific situation.
Proton Therapy
Proton therapy is a specialized form of radiation therapy used in the treatment of prostate cancer. It is a precise and targeted treatment that aims to deliver radiation directly to the tumor while minimizing damage to surrounding healthy tissues. Let’s explore how proton therapy works and the potential side effects and risks associated with this treatment.
How Proton Therapy Works
Proton therapy utilizes protons, which are positively charged particles, to deliver radiation to the prostate cancer cells. Unlike traditional radiation therapy, which uses X-rays or photons, proton therapy uses protons that have a unique characteristic called the Bragg peak. The Bragg peak refers to the ability of protons to deposit most of their energy at a specific depth within the body, which can be precisely controlled.
During proton therapy for prostate cancer, the protons are accelerated to high speeds and directed towards the tumor. The protons penetrate the body until they reach the tumor, where they deposit a significant amount of radiation energy. This allows for precise targeting of the tumor while sparing nearby healthy tissues.
Proton therapy is typically delivered in multiple sessions, known as fractions, over several weeks. The treatment plan is carefully designed by a team of radiation oncologists and medical physicists to ensure optimal coverage of the tumor while minimizing radiation exposure to critical structures such as the bladder and rectum.
Side Effects and Risks
Like any medical treatment, proton therapy for prostate cancer may have side effects and risks. However, the nature and severity of these side effects can vary from person to person. Some common side effects of proton therapy include:
- Fatigue: Many patients experience fatigue during the course of treatment, which tends to improve after completion.
- Skin Reactions: Some individuals may experience mild skin reactions, such as redness or irritation, in the treatment area. These reactions are usually temporary and resolve over time.
- Urinary Symptoms: Proton therapy can cause temporary urinary symptoms, such as increased frequency, urgency, or discomfort during urination. These symptoms typically subside after treatment.
- Rectal Symptoms: Some patients may experience temporary rectal symptoms, including bowel frequency, urgency, or mild rectal bleeding. These symptoms usually improve over time.
It’s important to note that the risk of long-term side effects from proton therapy is generally lower compared to traditional radiation therapy. However, rare complications can include urinary or rectal strictures, erectile dysfunction, or secondary malignancies. Your healthcare team will closely monitor your progress during and after treatment to address any concerns and manage potential side effects.
Proton therapy is a specialized treatment option that may be recommended for certain individuals with prostate cancer. It offers the advantage of highly targeted radiation delivery, which can result in effective tumor control while minimizing damage to surrounding healthy tissues. Your healthcare provider will consider various factors, such as the stage and characteristics of your prostate cancer, when determining the most appropriate treatment approach for you.
