How we choose who appears, how we pay for it, and what we do with your information.
Last updated October 31, 2026
Nobody can pay to be listed, ranked or described.
No one can pay to appear on Cancerify, to appear higher, to change how they're described, or to have anyone removed.
How doctors, hospitals and trials are chosen
Doctors
Specialists recognized at the state, national or international level, chosen on research, leadership and recognition.
Listed in alphabetical order.
Hospitals
Cancer centers chosen on reputation, expertise and standing in their country.
Listed in alphabetical order.
Clinical trials
Publicly registered trials, explained in plain language.
Latest phase first.
We don't rank
Lists are alphabetical, or by latest trial phase. We review listings regularly and remove anyone who no longer meets our criteria.
Where our money comes from
Cancerify is free for everyone. It’s paid for by a small number of clearly labeled ads, and by doctors, hospitals and trials that choose to claim their page. Neither affects who is listed or how.
We earn from
Sponsored ads
Approved companies pay to show clearly labeled ads. Doctors, hospitals and trial sponsors can never buy ads.
Page claiming
An optional yearly fee from doctors, hospitals and clinical trials that choose to claim their page. Nobody has to, and unclaimed pages are treated exactly the same.
We never earn from
Payment to be listed, moved up or described differently.
Payment to remove a competitor.
Ads from doctors, hospitals or trial sponsors.
Selling or sharing your information.
Ads
Every ad is marked Sponsored with the company's name and is reviewed before it runs. Tap the ⓘ on any ad to see why you're seeing it.
No medical claims.
No fear or pressure.
Always labeled Sponsored, with the company’s name.
Never targeted at you. Everyone on a page sees the same ad.
Advertisers see totals only, never who.
Claimed pages
A doctor, hospital or clinical trial can claim their own page after we verify who they are. Claiming is an optional yearly plan that lets them keep their own details current. It never changes why they’re listed, where they appear, or whether they stay listed.
A claimed page can update
Their own details, such as contact information, insurance and specialties. Every change is checked before it goes live.
A claimed page can never change
Why they're listed, the description we wrote, or whether they appear. Claimed and unclaimed pages look the same.
Your information
What you search for here is health information, and we treat it that way.
We count, in totals only
How many people visit, search or open a profile.
Which cancers and places are searched most, only from people who allow it.
Sign-ups and sign-ins, which your account needs to work.
