This application estimates your general risk of cancer, as well as the risk of 38 types of different cancers, based on roughly 650 different risk factors described in the scientific literature. Results are displayed for lifetime risk as well as for 10-, 20- and 30-year timeframes, as well as the risk of death from the cancer in question. A subdivision in anatomical or pathological subtypes is provided if possible. Detailed references are provided for the impact of each risk factor.

Additionally, over 90 published & validated cancer models have been included in the application, providing more detail for interested users.

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.

Introduction

The Cancer Risk Calculator is a tool designed to estimate an individual's risk of developing certain types of cancer based on their personal and lifestyle factors. It is a valuable resource for individuals who are concerned about their cancer risk or who are seeking information to make informed health decisions.

How the Calculator Works

The Cancer Risk Calculator utilizes a complex algorithm that takes into account various factors, including:

* Age

* Gender

* Family history of cancer

* Personal medical history

* Lifestyle habits (e.g., smoking, alcohol consumption, physical activity)

* Environmental exposures (e.g., radiation, chemicals)

By analyzing these factors, the calculator generates an estimate of the user's risk for developing specific types of cancer, such as breast, prostate, lung, and colon cancer.

Limitations and Considerations

It is important to note that the Cancer Risk Calculator is an estimation tool, and its results should not be considered a definitive diagnosis or a substitute for medical advice. The calculator has certain limitations, including:

* It cannot predict all types of cancer.

* It is based on population-level data and may not accurately reflect an individual's unique risk factors.

* The accuracy of the results depends on the accuracy of the information provided by the user.

Uses of the Calculator

Despite its limitations, the Cancer Risk Calculator can be a useful tool for:

* Raising awareness about cancer risk factors.

* Motivating individuals to adopt healthier lifestyles.

* Encouraging people to get regular cancer screenings.

* Providing a starting point for conversations with healthcare providers about cancer prevention and early detection.

Interpreting the Results

The results of the Cancer Risk Calculator are typically presented as a percentage, which represents the estimated lifetime risk of developing a specific type of cancer. It is important to understand that this percentage does not mean that an individual is certain to develop cancer, but rather that they have a higher risk compared to the general population.

Additional Factors to Consider

In addition to the factors considered by the Cancer Risk Calculator, there are other factors that can influence an individual's cancer risk, such as:

* Genetic mutations

* Immune system function

* Stress levels

* Diet and nutrition

Conclusion

The Cancer Risk Calculator is a valuable tool that can provide individuals with an estimate of their risk for developing certain types of cancer. While it has limitations, the calculator can be used to raise awareness, motivate healthier lifestyles, and encourage regular cancer screenings. It is important to interpret the results cautiously and to consult with a healthcare provider for further guidance and personalized risk assessment.
