How to Search Cancer FactFinder's Claim Database or Submit a New Cancer Claim Topic

Cancer FactFinder lets you look up whether a specific exposure, product, or habit is linked to cancer, and it also accepts topic suggestions from the public. You can search the existing claim database by keyword, browse by category, or submit a new claim idea through the form on the site. Submitting is useful when you can't find your question already answered — the site says it shares public concerns with its research team and can notify you by email if the topic is added.

Searching the claim database

The homepage provides a search box directly under the line "Find a claim in our database, or submit a new claim topic below for our research team to consider." Enter your topic (for example, a product, food, or exposure) and run the search to see whether a matching claim exists.

If you prefer to browse instead of search, the site organizes claims into Claim Categories, with the number of entries shown for each:

Browsing by category is helpful when you don't have a precise search term and want to see what topics the site already covers in your area of concern.

Submitting a new claim topic

If your question isn't in the database, the homepage form lets you propose it for the research team to consider. The form asks for:

• Email (required)
• Name (required)
• Category — choose from Consumer products, Diet & nutrition, Lifestyle, Medical Issue or Treatment, Occupational & environmental exposure, or Other
• A topic idea — described on the page as "Enter a topic idea here"
• An opt-in checkbox — "Let me know if this topic is added to the Cancer FactFinder"
• Consent to the Privacy policy and to processing of your personal data

The page states that you can "Submit your ideas for claim topics that our team should consider," and that public concerns shared through the form will be passed to the research team.

What the site is actually for

Cancer FactFinder describes its purpose as answering "What actually causes cancer – and what doesn't?" It says it summarizes "the best evidence-based scientific information available from studies in humans" and presents that research "in everyday language." Its stated goals are to debunk cancer myths, help users become skilled factcheckers, and share trustworthy prevention resources. It also says it provides strategies for evaluating information about cancer causes so you can be a wiser consumer of news and social media, and connects users to reliable material from established experts, including books, apps, and podcasts.

Practical notes

• The site does not state any pricing, login requirement, or paywall for searching or submitting, so treat access conditions as unconfirmed rather than assuming it is free or open.
• Email and name are marked required on the submission form, so plan to provide them if you want your topic considered.
• Checking the notification box is optional and only affects whether you hear back about your topic.
• Submitting a topic does not guarantee it will be added — the page frames it as an idea for the research team to consider.
