Enter your age, whether you’ve had a previous breast biopsy, and the number of first-degree relatives with breast cancer into the calculator to estimate your Tyrer-Cuzick score for breast cancer risk.
Tyrer-Cuzick Score Formula
The Tyrer-Cuzick model uses a complex algorithm that includes various factors such as age, family history, and other risk factors to estimate the likelihood of developing breast cancer. For the purpose of this example, a simplified version of the formula is used:
TC Score = Age * 0.2 + Biopsy * 0.3 + Relatives * 0.5
Variables:
- Age is the current age of the individual.
- Biopsy indicates whether the individual has had a previous breast biopsy (0 for no, 1 for yes).
- Relatives is the number of first-degree relatives with breast cancer.
To estimate the Tyrer-Cuzick score, input the individual’s age, biopsy history, and number of affected first-degree relatives into the simplified formula.
What is the Tyrer-Cuzick Score?
The Tyrer-Cuzick score is an estimate of a woman’s risk of developing breast cancer based on personal and family history factors. It is used by healthcare professionals to help determine the level of breast cancer screening and prevention strategies that may be appropriate for an individual.
How to Calculate the Tyrer-Cuzick Score?
The following steps outline how to estimate the Tyrer-Cuzick score using the simplified formula:
- First, determine the individual’s current age.
- Next, determine if the individual has had a previous breast biopsy (0 for no, 1 for yes).
- Then, count the number of first-degree relatives with breast cancer.
- Use the simplified formula to estimate the Tyrer-Cuzick score.
- 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 = 30 years
Previous Breast Biopsy = 1 (yes)
Number of First-Degree Relatives with Breast Cancer = 2
