Cancer risk assessment is the process of estimating an individual’s likelihood of developing cancer. It is based on a variety of factors, including age, sex, family history, lifestyle choices, and environmental exposures. The most common method of cancer risk assessment is the Gail model, which was developed by researchers at the National Cancer Institute. The Gail model takes into account a woman’s age, race, ethnicity, reproductive history, and family history of breast cancer to estimate her risk of developing breast cancer over the next five years.
Cancer risk assessment can be used to help women make informed decisions about their health. For example, women who are at high risk of developing breast cancer may choose to take preventive measures, such as taking medication or having regular mammograms. Cancer risk assessment can also be used to help doctors develop personalized treatment plans for women who have been diagnosed with breast cancer.
Cancer risk assessment is an important tool for helping women understand their risk of developing cancer and making informed decisions about their health. It is a complex process, but it can be a valuable tool for women who are concerned about their risk of developing cancer.
