What is a modifiable risk factor for cancer?

Appeared in: NIMHANS Nursing Officer - 2021

Explanation

Smoking is classified as a modifiable risk factor because it is a lifestyle behavior that an individual can choose to change or stop.
Quitting smoking is one of the most effective single actions to reduce the risk of developing many types of cancer, making it a key target for primary prevention.
Modifiable risk factors, unlike non-modifiable ones like age or genetics, are the focus of health promotion and patient education to actively lower cancer incidence.

Option B: Age is the single most significant non-modifiable risk factor for cancer. The risk of developing cancer increases as a person gets older, and this cannot be changed.
Option C: Biological sex is a non-modifiable risk factor. It influences the likelihood of developing sex-specific cancers like prostate or ovarian cancer.
Option D: Hereditary factors, such as inherited genetic mutations, are non-modifiable. A person cannot change their genetic makeup.

Clinical Relevance

Nursing practice connection: This is primarily an exam-oriented knowledge point with limited direct bedside application, so retain Modifiable vs. Non-modifiable Cancer Risk Factors as background academic context rather than a clinical decision trigger.
Nurses play a crucial role in patient education by identifying and discussing modifiable risk factors to empower patients to make healthier lifestyle choices, which is a cornerstone of primary cancer prevention.
Assessing for non-modifiable risk factors like family history is essential for recommending appropriate cancer screening schedules and potential genetic testing, which falls under secondary prevention (early detection).
What if? - If a patient has a strong non-modifiable risk factor (e.g., a known BRCA gene mutation), the nursing priority shifts from focusing solely on primary prevention (lifestyle) to emphasizing secondary prevention (early detection through intensive screening) and discussing tertiary prevention options (e.g., risk-reduction surgery).

How to Approach the Question

First, identify the key term in the question: 'modifiable risk factor'.
Define 'modifiable' in a healthcare context. It means something that can be changed by a person's actions or choices.
Evaluate each option against this definition.
Consider 'Smoking': This is a behavior that can be stopped. Thus, it is modifiable.
Consider 'Age', 'Sex', and 'Hereditary': These are inherent characteristics that a person cannot change.
Conclude that smoking is the only option that fits the definition of a modifiable risk factor.
