Breast cancer risk factor includes, except?

Appeared in: NORCET 5 Prelims - Sept 2023 (Shift-2)

Explanation

The question requires identifying the option that is NOT a risk factor for breast cancer.
Being a 'Younger woman' is associated with a significantly lower risk of developing breast cancer. The incidence and risk increase dramatically with age.
Therefore, 'Younger women' is the exception among the given options and the correct answer.

Option A: This is a primary non-modifiable risk factor. The risk of breast cancer increases significantly as a woman gets older, with most cases diagnosed after age 50.
Option B: This is a known modifiable lifestyle risk factor. Research shows that the more alcohol a woman drinks, the higher her risk of breast cancer.
Option C: This is a significant non-modifiable risk factor. Having a first-degree relative (mother, sister, or daughter) with breast cancer approximately doubles a woman's risk.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Risk Factors for Breast Cancer as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in educating patients about breast cancer risk factors, differentiating between modifiable (e.g., alcohol, obesity) and non-modifiable (e.g., age, family history) risks.
This knowledge is essential for promoting lifestyle changes, encouraging adherence to screening guidelines (like mammograms), and identifying high-risk individuals who may need genetic counseling or more intensive surveillance.
What if? If the question asked for a modifiable risk factor, 'High consumption of alcohol' would be a correct answer, as it's a lifestyle choice that can be changed, unlike age or family history.

How to Approach the Question

First, identify the keyword 'except' in the question stem. This signals that you need to find the option that does not fit with the others.
The question is asking for something that is NOT a risk factor for breast cancer.
Evaluate each option based on your knowledge. Is 'Older women' a risk factor? Yes. Is 'High consumption of alcohol' a risk factor? Yes. Is 'Family history' a risk factor? Yes.
Evaluate the final option: Is 'Younger women' a risk factor? No, the risk is significantly lower in younger women and increases with age.
Conclude that 'Younger women' is the correct answer because it is the exception.
