Managing Side Effects from Prostate Cancer Treatment

Side effects are a common part of prostate cancer treatment, but there are many evidence-based strategies to prevent and manage them. Let me walk you through the main approaches.

Understanding Your Treatment Options & Their Side Effects

Different prostate cancer treatments cause different side effects:

Surgery (Radical Prostatectomy):

  • Urinary incontinence (leaking urine)
  • Erectile dysfunction (difficulty with erections)
  • Bowel changes

Radiation Therapy:

  • Urinary symptoms (frequency, urgency, burning)
  • Bowel symptoms (diarrhea, urgency)
  • Erectile dysfunction (develops over time)

Hormone Therapy:

  • Hot flashes
  • Fatigue
  • Weight gain
  • Bone loss
  • Erectile dysfunction

Chemotherapy:

  • Nausea and vomiting
  • Fatigue
  • Hair loss
  • Low blood counts

Evidence-Based Prevention & Management Strategies

Before Treatment Starts

According to NCCN Prostate Cancer Guidelines, patients should:

  • Discuss expected side effects with your team BEFORE treatment begins
  • Ask about supportive care options available to you
  • Consider pelvic floor physical therapy BEFORE surgery (can improve continence outcomes)
  • Establish baseline erectile function with your doctor

Managing Urinary Side Effects

  • Pelvic floor exercises (Kegel exercises): Strengthening these muscles helps with incontinence. Ask your doctor for a referral to a pelvic floor physical therapist
  • Fluid management: Limit fluids before bed; avoid caffeine and alcohol
  • Scheduled voiding: Urinate on a regular schedule rather than waiting for urgency
  • Protective products: Absorbent pads or undergarments during recovery
  • Medications: Your doctor may prescribe medications to help with urgency or frequency

Managing Erectile Dysfunction

The American Cancer Society recommends:

  • Phosphodiesterase-5 inhibitors (medications like sildenafil/Viagra, tadalafil/Cialis) - often effective, especially if started early
  • Penile rehabilitation: Starting erectile function treatments early after surgery may improve long-term outcomes
  • Vacuum erection devices: Non-medication option that can be effective
  • Counseling: Sexual dysfunction can be emotional; talking with a therapist helps
  • Communication: Discuss options with your partner and healthcare team

Managing Hot Flashes (Hormone Therapy)

  • Lifestyle changes: Dress in layers, keep environment cool, avoid triggers (spicy food, hot drinks, stress)
  • Medications: Your doctor may prescribe medications specifically for hot flashes
  • Complementary approaches: Some patients find acupuncture or mindfulness helpful (discuss with your team)

Managing Fatigue

  • Exercise: Regular physical activity (walking, strength training) improves energy levels
  • Sleep hygiene: Maintain consistent sleep schedule
  • Nutrition: Eat balanced meals; ask about seeing a nutritionist
  • Pacing: Balance activity with rest periods

Managing Bone Health (Hormone Therapy)

According to NCCN Guidelines, patients on long-term hormone therapy should:

  • Get baseline bone density screening (DEXA scan)
  • Take calcium and vitamin D supplements as recommended
  • Engage in weight-bearing exercise
  • Avoid smoking and limit alcohol
  • Your doctor may prescribe bone-protective medications if needed

Managing Bowel Side Effects (Radiation)

  • Dietary changes: Increase fiber gradually, stay hydrated
  • Medications: Anti-diarrheal medications can help
  • Avoid triggers: Limit spicy foods, caffeine, high-fat foods during treatment
  • Rectal care: Gentle hygiene; ask about medicated suppositories if needed

Questions to Ask Your Healthcare Team

  1. "What side effects are most likely with MY specific treatment plan?"
  2. "What supportive care services are available to me (physical therapy, counseling, nutrition)?"
  3. "When should I contact you about side effects—which ones are urgent?"
  4. "Are there medications or treatments to prevent or manage specific side effects?"
  5. "Can you refer me to a specialist (pelvic floor PT, sexual medicine specialist, etc.)?"
  6. "What lifestyle changes would help manage my side effects?"

Key Takeaway

Proactive management works best. The more you communicate with your care team about side effects—both before and during treatment—the more options they have to help you. Many side effects can be prevented or significantly reduced with the right approach.
