Why Asking Questions Matters

Your oncologist has limited time during each appointment. Coming prepared with thoughtful questions helps you get the most out of every visit and ensures you fully understand your diagnosis and treatment plan.

Questions About Your Diagnosis

  • What type of cancer do I have, and what does that mean?
  • What stage is my cancer, and what does that stage mean for my prognosis?
  • Has the cancer spread to other parts of my body?
  • What are my pathology results, and can you explain them in simple terms?
  • What biomarkers or genetic mutations are present in my tumor?

Questions About Treatment

  • What are my treatment options?
  • What treatment do you recommend, and why?
  • What is the goal of treatment — cure, control, or comfort?
  • Are there any clinical trials I might qualify for?
  • Should I get a second opinion?

Questions About Side Effects

  • What side effects should I expect from this treatment?
  • Which side effects should I call about immediately?
  • How will this treatment affect my daily life?
  • Are there ways to prevent or manage side effects?

Questions About Next Steps

  • How will we know if the treatment is working?
  • How often will I need to come in for appointments?
  • What happens if this treatment stops working?
  • Who should I call if I have questions between appointments?
