- absolute risk
- listen (AB-soh-loot risk)
- A measure of the risk of a certain event happening. In cancer research, it is the likelihood that a person who is free of a specific type of cancer at a given age will develop that cancer over a certain period of time. For example, a woman 35 years of age, with no known risk factors for breast cancer, has an absolute risk of getting breast cancer over a lifetime of 90 years of about 13.5%, meaning one out of every seven women will develop breast cancer.
