d) using electronic cigarettes rather than traditional tobacco products

Explanation:

🆕 New Concept Discovered: Cancer Risk Reduction Strategies
Proactive lifestyle choices to lower cancer risk.

Step 1: Analyze option (a)

Charring food on a grill creates heterocyclic amines (HCAs) and polycyclic aromatic hydrocarbons (PAHs). These chemicals are known mutagens and carcinogens that can actually increase the risk of cancer. Therefore, this is not an effective risk-reduction strategy.

Step 2: Analyze option (b)

Fruits and vegetables are rich in antioxidants, vitamins, minerals, and dietary fiber. Antioxidants help neutralize free radicals, which are unstable molecules that can damage DNA and lead to cancer. Health organizations widely recommend consuming a high volume of fruits and vegetables (such as 7–13 servings daily) to significantly lower the risk of various cancers.

Step 3: Analyze option (c)

Tanning beds and lamps emit ultraviolet (UV) radiation, which directly damages skin cells and is a proven group 1 carcinogen. Using them does not reduce cancer risk; instead, it significantly increases the risk of developing melanoma and other skin cancers.

Step 4: Analyze option (d)

While electronic cigarettes may contain fewer harmful chemicals than traditional combustible tobacco, they still contain nicotine, heavy metals, and other volatile organic compounds that pose health risks. Switching to e-cigarettes is not a primary, universally recommended strategy for reducing cancer risk compared to complete avoidance of inhalation products and adopting a nutrient-rich diet.

Answer:

b) consuming 7–13 servings of fruits and vegetables every day
