You do not need a diagnosis to act. Three steps give you a clear picture of your risk to bring to your doctor.
Answer honest questions about diet, activity, and habits to see what raises your risk and what lowers it most.
STEP 02Map the cancers and conditions in your blood relatives. This is the single strongest signal of inherited risk.
STEP 03Decide, with a clinician, what type of genetic screening is right for you.
A large share of cancer risk comes from things you can change. These two free tools turn decades of research into a personal estimate and a short list of the changes that lower your risk the most. Pick the one that fits how you like to think. Both take about ten minutes.

Take the assessmentWorld Cancer Research Fund
A free, international tool that turns the latest prevention evidence into a personal set of changes. It covers diet, weight, activity, alcohol, and smoking, and shows where you are doing well and where to focus. It looks at lifestyle, not family history, so use it alongside the tools above.
Your family history is the most useful information you can bring to a doctor, and most of us have never written it down. A clear record helps a clinician spot inherited patterns and decide whether you need earlier or more frequent screening.
Created by the U.S. Surgeon General, maintained by the CDC. Free.
The standard tool clinicians trust. It turns what you enter into a professional pedigree, the family tree and medical chart that genetic counselors and oncologists use to read hereditary risk. You can log the exact age of each diagnosis and cause of death for immediate and extended blood relatives.
Your privacy is protected by design. The CDC does not save or store what you enter. The information stays in your browser and you download the file to keep on your own computer. You can share that file with relatives so they can build their own history without starting over.
Available worldwide. It builds a standard pedigree any clinician anywhere can read, and the CDC stores none of your data. It uses US units, so enter height in feet and inches. If you prefer metric, use FastFamilyTree below.
Built by genetic counselors
A free, browser-based alternative that works anywhere and is metric-friendly. It follows current pedigree standards and stores none of your personal health information, the same privacy model as the Portrait.
Your lifestyle and family history tell you a lot. Genetic screening can fill in the rest. There are two different kinds, and they answer two different questions. A doctor or genetic counselor can help you decide which, if either, is right for you.
Reads the DNA you were born with to find inherited mutations, such as BRCA, that raise your lifetime cancer risk. Most useful when cancer runs in your family.
A blood test that looks for signals of cancer that may already be present, often before symptoms. Newer, and best used alongside, not instead of, standard screening.
