Prostate Cancer: Managing the Side Effects of Radiation Therapy

Radiation therapy is a common and effective treatment for prostate cancer in Singapore, targeting cancer cells while aiming to preserve healthy tissue. However, like many cancer treatments, it can lead to side effects that affect quality of life. Understanding these side effects and how to manage them is a key part of comprehensive prostate cancer care and men’s cancer care Singapore.

Common Radiation Therapy Side Effects

1. Urinary Symptoms

Patients may experience increased frequency, urgency, or discomfort during urination. Some might notice blood in the urine or have difficulty controlling urine flow. These symptoms usually appear during treatment and can last for weeks or months afterward.

2. Bowel Changes

Due to the prostate’s proximity to the rectum, radiation can cause inflammation leading to bowel urgency, diarrhea, rectal pain, or rectal bleeding. Without protective measures, up to 30% of patients can experience such side effects, affecting daily life.

3. Fatigue

Fatigue is common during radiation therapy and can persist after treatment ends. It differs from regular tiredness and may not improve with rest, requiring lifestyle adjustments and support to manage.

4. Sexual Dysfunction

Radiation can affect erectile function, leading to difficulties in achieving or maintaining an erection. This side effect varies among patients and can be influenced by age and baseline sexual health.

5. Skin Reactions

The treated area may develop redness, dryness, itching, or mild blistering, similar to a sunburn. These effects are generally temporary and manageable.

Advances in Minimizing Side Effects: Rectal Spacers

Singapore hospitals, including National University Hospital (NUH), have introduced rectal spacer technology—a biodegradable gel injected between the prostate and rectum. This spacer physically pushes the rectum away from the radiation field, significantly reducing rectal side effects such as bleeding and discomfort.

Studies show that patients treated with rectal spacers experience a drastic reduction in severe rectal side effects—from about 30% to under 5%. The spacer dissolves naturally within 6-9 months and improves patients’ quality of life during and after radiation therapy.

Managing Side Effects

• Hydration: Drink plenty of fluids to ease urinary symptoms.
• Pelvic Floor Exercises: Help strengthen muscles to improve urinary control.
• Dietary Adjustments: Avoid spicy, acidic, or irritant foods to reduce bowel discomfort.
• Medications: Your doctor may prescribe medications to manage symptoms such as diarrhea, pain, or inflammation.
• Fatigue Management: Balance rest with gentle exercise and proper nutrition; seek support when needed.
• Sexual Health Support: Various therapies, including medications and counseling, can help manage erectile dysfunction.

Support and Follow-Up in Singapore

Men undergoing radiation in Singapore benefit from integrated care involving urologists, oncologists, radiation therapists, and support services. Regular follow-ups help monitor and address side effects early, ensuring timely interventions and improved recovery.

Radiation therapy side effects are common but largely manageable with the right care and advancements like rectal spacers. Proactive communication with your healthcare team about symptoms can help tailor supportive measures to maintain your quality of life throughout cancer treatment Singapore and beyond.
