Sarah Cannon - September 14, 2020

When you receive a cancer diagnosis, it is only natural to want to find out as much as possible about the disease, your treatment options, and what your cancer journey might look like. While your care team should be your first source of knowledge, you may also find yourself turning to the Internet for more information.

How to find reliable cancer information online

Unfortunately, not everything on the Web is accurate or reliable, and some sites are so inaccurate that they can be downright dangerous. For help in separating fact from fiction and good information from misinformation, the National Cancer Institute's Using Trusted Resources page has excellent questions to ask, such as:

  1. Who is publishing the information, and who paid or sponsored it? (Tip: Check the "About Us" or Disclaimers' section.)
  2. Is the original source (research study or medical journal) identified?
  3. Who reviewed the information before it was posted? (Tip: Check for credentials such as MD, DO or PhD.)
  4. How current is the information, and when was it last reviewed?
  5. What is the web address? (Tip: Generally, you can trust websites that end in “.gov” and “.edu”. Review sites that end with “.org” and “.com” just to be sure the information is credible.)
  6. If personal information is being asked, how it is being used and how are you protected?

Seven cancer information sites you can trust
