This application estimates your risk of cancer, subdivided into 26 types and based on 350 different risk factors described in the scientific literature. Results are displayed for 10-, 20- and 30-year timeframes, with a subdivision in anatomical or pathological subtypes if possible.
This application has the CE conformity mark as a medical device with a low risk. As such, we have followed the Class I conformity assessment procedures as described in Annex VII Module A, EC Declaration of Conformity. As it it is considered a medical device that poses minimal risk to patients and consumers, it falls under the FDA exercise enforcement discretions. For more information, please visit the relevant section the official FDA website: https://www.fda.gov/medical-devices/mobile-medical-applications/examples-mobile-apps-which-fda-will-exercise-enforcement-discretion
To use this application, create an account and enter the requested information in the different tabs as accurately and completely as you can. All information that is requested will influence your risk for at least one type of cancer, so the more complete and accurate the information you enter, the more dependable the results. Age, gender and racial background are critical, all other information is optional. The results will appear after you have completed the last tab and can always be revisited by tapping your name. You can also edit the information you submitted to see how this influences your results.
The lifetime probabilities of developing cancers were based on USA data from the National Cancer Institute's (NCI's) Surveillance, Epidemiology, and End Results (SEER) Program, collected since 1973 and by the Centers for Disease Control and Prevention's (CDC's) National Program of Cancer Registries (NPCR), collected since 1995. These figures were adapted by the hazard ratios available in the published peer-reviewed literature. Only risk factors with a quantifiable risk were included. Risk factors requiring complex tests not available to the average clinician were excluded. Meta-analyses were given preference when available.
DISCLAIMER: This application is strictly educational and all information contained herein cannot and should not replace assessment by a physician. The evaluations presented represent our best efforts to conveniently assess cancer risk. However, as significant controversy and widely different study results can persist around the impact of even a single variable in a strictly selected population, this is based on a large number of assumptions, extrapolations and estimates. As not every study includes a multivariate analysis and the effect of some risk factors on certain cancers is so large their effect cannot be eliminated from basic probability, a bias toward overestimation of risk is possible. Furthermore, there is continuous progress in the scientific literature. Any figures should therefore be regarded as indicative, but not precise.
Any information you enter into this application will only be stored on your device and will never be sent to us or to any other party, for any reason.
All research and medical support for this application was done by Dr. Philippe Westerlinck, radiation oncologist and clinical chair at the University Hospital of Liège, superspecialising in gastro-intestinal, lung and breast cancers.
This is one of the most informative and easy-to-use apps I’ve ever used. The information provided on risk factors is easily digestible. The way it is designed for you to check off risk factors is easy to use and thorough.
A great idea that doesn’t hold up to scrutiny

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.
Great for nurses and other overthinkers

Now when we think “Hey, this hurts, it’s probably cancer” we can quantify it with an actual percentage! Really excellent source of information/motivation.
Questionable utility?

People, just go see your doctor. An app with data this sparse and analysis this shallow isn’t going to help you identify your cancer risk, nor will it provide meaningful insight into lifestyle changes.Thanks for clarifying the relationship with Google/Admob. It seems reasonably clear that your personal health data remains on the device.
Developer Response
We developed this app to just give users an indication of their cancer risk compared to the average population risk. This is based on a significant amount of scientific studies, but it will always be an estimation. But we do advice people (this is also mentioned in the app) to still consult a doctor when you want a more detailed analysis.As mentioned in the privacy policy, we only store the data on your device, not in the cloud. The only data shared with Google and AdMob is that you as a user have downloaded an are using a medical app. They use this information to tailor the ads to show you. Privacy is very important to me, so I really monitored this. But since we are a software developer and a doctor, our legal jargon could be lacking to make this clear in the privacy policy. If you have any suggestions on how to change the wording in our policy to avoid confusion in the future, you may contact us and we will gladly change it.
