Cancer and other health information, whether in print or online, should come from a trusted, credible source. Government agencies, hospitals, universities, and medical journals and books that provide evidence-based information are sources you can trust.
Unfortunately, it has become very common for false or misleading information to be found online and in print. If a source makes claims that are too good to be true, remember—they usually are.
There are many resources that provide cancer and other health information to the public, but not all of them are trustworthy. Use the tips below to protect yourself when looking for health information.
There are so many websites with cancer information that it can be hard to know which ones to trust. Credible sources of cancer and other health information should make it easy for people to learn who is posting the content. They should make clear the original source of the information, along with the expert credentials of the people who prepare or review the online material.
Ask the following questions to decide if health information online is credible:
It’s common to go to social media sites to find cancer information. These sites (such as Facebook, Instagram, YouTube, Twitter) can be helpful when they’re up-to-date and trustworthy. They also can be good ways for people to connect with others who have similar health issues and questions.
It’s important to only follow social media from reputable sources. Ask the same questions when using social media that you would ask for using a website. Many trusted organizations have social media accounts that link to their websites. For example, the National Cancer Institute has official Facebook, Instagram, YouTube, and Twitter pages in English and Spanish.
Related, mobile apps are often used to track health activities, such as diet and exercise. Some people use them to record medicine schedules or doctor visits. Using these methods can be very useful. However, not all are reliable or safe. Seek advice from your medical team or others you trust before using them.
Always use caution when using your email or texting. Do not click on a link in a message unless you know or trust the sender. And never open an attachment unless it comes from a trustworthy source. This is true whether you’re on your phone or your computer.
When it comes to personal social media accounts, it’s common for users to post their experiences with cancer. This may include
But remember that everyone is different. Even someone with the exact same kind of cancer has a different body and health history from you. Never take recommendations for treatment or medicines from someone other than your doctor. You don’t know where or how the user got their information. You also don’t know if the information is current or what the user’s knowledge of cancer is.

If you want to look for articles about cancer that you can trust, search online medical journal databases or ask a librarian for guidance. (Or if you live near a college or university, there may be a medical library you can use.) They can help you look for medical journals, books, and other research in cancer that has been done by experts. Two trusted sites for articles include PubMed and MedlinePlus, both from the National Library of Medicine.
Articles in popular magazines are usually not written by experts. Rather, the authors speak with experts, gather information, and then write the article. If claims are made in a magazine, remember the below.
When you read articles about cancer, you can use the same process that the article writer uses:
A number of books have been written about cancer, cancer treatment, and complementary and alternative medicine (CAM). Some books contain trustworthy content, while others do not.
It’s important to know that information is always changing and that new research results are reported every day. By the time a book is published, the contents may be outdated. Also, be aware that if a book is written by only one person, you may only be getting that one person’s view.
If you go to the library, ask the staff for suggestions. Local bookstores may also have people on staff who can help you. If you find a book online, look very carefully at the author’s credentials, background, and expertise. Questions you may want to ask yourself are:
