Enter your age, the number of breast biopsies you’ve had, and the number of first-degree relatives with breast cancer into the calculator to estimate your Gail Score, which represents your 5-year risk of developing breast cancer.

Gail Score Formula

The Gail Score is calculated using a complex statistical model that takes into account various risk factors. For the purpose of this example, a simplified version of the formula is used:

GS = (Age * 0.1) + (Biopsies * 0.2) + (Relatives * 0.3)

Variables:

  • GS is the Gail Score (5-year risk %)
  • Age is the age of the individual in years
  • Biopsies is the number of breast biopsies the individual has had
  • Relatives is the number of first-degree relatives with breast cancer

To estimate the Gail Score, input the individual’s age, number of breast biopsies, and number of first-degree relatives with breast cancer into the simplified formula.

What is a Gail Score?

The Gail Score is a statistical tool used to estimate a woman’s risk of developing breast cancer over the next 5 years. The score is based on a model that includes risk factors such as age, family history, reproductive history, and history of breast disease. It is used by healthcare providers to help make decisions about breast cancer screening and prevention strategies.

How to Calculate Gail Score?

The following steps outline how to estimate the Gail Score using the simplified formula:


  1. First, determine the individual’s age in years.
  2. Next, determine the number of breast biopsies the individual has had.
  3. Next, determine the number of first-degree relatives with breast cancer.
  4. Use the simplified formula to estimate the Gail Score.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

Age = 40 years

Number of Breast Biopsies = 1

Number of First-Degree Relatives with Breast Cancer = 2
