Tyrer-Cuzick Score Calculator

Formula

The formula to calculate the Tyrer-Cuzick score is:

\[ \text{TC Score} = \text{Age} \times 0.2 + \text{Biopsy} \times 0.3 + \text{Relatives} \times 0.5 \]

Where:

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.

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.

Example Calculation 1

Let's assume the following values:

Age = 45
Previous Breast Biopsy = 1
Number of First-Degree Relatives with Breast Cancer = 2

Using the formula:

\[ \text{TC Score} = 45 \times 0.2 + 1 \times 0.3 + 2 \times 0.5 = 9 + 0.3 + 1 = 10.3 \]

The Tyrer-Cuzick score is 10.3.

Example Calculation 2

Let's assume the following values:

Age = 50
Previous Breast Biopsy = 0
Number of First-Degree Relatives with Breast Cancer = 1

Using the formula:

\[ \text{TC Score} = 50 \times 0.2 + 0 \times 0.3 + 1 \times 0.5 = 10 + 0 + 0.5 = 10.5 \]

The Tyrer-Cuzick score is 10.5.
