According to the National Comprehensive Cancer Network (NCCN) Guidelines for Prostate Cancer Patients, here are key preparation steps:

Physical Preparation:

  1. Maintain a consistent bladder-filling routine
  • Drink a specific amount of water (usually 2-3 cups) about 1 hour before each treatment
  • Empty your bladder, then drink water as instructed
  • This helps protect your bladder and ensures consistent positioning
  1. Bowel preparation
  • Follow a regular schedule for bowel movements
  • Avoid gas-producing foods
  • Your radiation team may provide specific dietary guidelines

The American Cancer Society recommends these additional preparation steps:

  • Continue normal daily activities unless advised otherwise
  • Get adequate rest
  • Eat a balanced, nutritious diet
  • Stop smoking if you currently smoke, as it can affect treatment effectiveness

According to ASTRO (American Society for Radiation Oncology) guidelines, you should expect:

  • A planning session (simulation) before starting treatment
  • Creation of small skin marks or tiny tattoos to ensure precise positioning
  • Discussion about side effect management
  • Regular check-ups during treatment

Important recommendations from all sources:

  1. Bring all questions to your radiation oncology team
  2. Report any new symptoms or concerns promptly
  3. Follow all specific instructions from your treatment team, as they may vary based on your particular situation

Always consult with your healthcare team for personalized preparation instructions, as they may have additional requirements based on your specific treatment plan.
