User Reviews

User feedback on Cancer Risk Calculator is mixed. Several reviewers praise the app for being easy to use and offering reassurance about risk, with some noting it motivates regular checkups. However, a majority raise concerns about accuracy and the underlying methodology, describing the results as unreliable or simplistic. Privacy worries are common, including potential data sharing and selling of health information, alongside skepticism about the app's medical credentials (not created by doctors). A few users also mention device-specific UI issues and incomplete content. Overall, it may raise awareness but should not be relied on for medical decisions.

Pros

Easy to use / user-friendly interface (multiple reviews mention this)
Provides motivation/reassurance for users about cancer risk (mentioned by users who felt calmer about their risk)

Cons

Inaccurate results and questionable methodology (consistently raised by reviewers)
Privacy concerns and potential data sharing or selling of health data (noted across several reviews)
Skepticism about medical credibility (not created by a doctor / reliance on unverified sources)

Recent reviews

Several pop-up menus are truncated by edge of screen (iPhone 15 plus), so is unusable.

I found this app when the developer posted it in the /medicine subreddit on Reddit. It got thoroughly panned there by other docs for the methodology used, which seems to give quite inaccurate results. Still, I tried it out myself. I was surprised to see my breast cancer risk as lower than the general population, since I have several family members with histories of breast cancer. Same for cervical cancer, which I should be at higher risk for, given my HPV+ status and history of cervical dysplasia. Then I realized the app did not ask for HPV status or results of Pap smear tests - seems odd to offer a risk analysis of cervical cancer and not include those. Overall, just doesn’t seem trustworthy. I would not encourage anyone to make healthcare decisions based on this app.

All thought it was very inaccurate. Reviews this year there so bad, the mods of r/medicine took the post down so that the link could not be used. Ask your doctors about your cancer risks, that’s what you pay them for. Wish I could give zero stars
