Verified step by step guidance

1. Understand the question: The problem asks which action does NOT help in decreasing the risk of cancer. This means we need to identify the action that is not supported by evidence as a cancer risk-reducing behavior.
2. Analyze each option: Start by evaluating the scientific basis of each action in relation to cancer prevention. For example, quitting tobacco use is well-documented to reduce cancer risk, as tobacco is a major carcinogen.
3. Evaluate the option 'Drinking red wine instead of white wine': While moderate alcohol consumption has been associated with certain health benefits, alcohol consumption in general is linked to an increased risk of several types of cancer. Therefore, substituting one type of alcohol for another does not reduce cancer risk.
4. Consider the other options: Using sunscreen helps protect against skin cancer by reducing UV exposure, and being physically active is associated with a lower risk of several cancers due to its role in maintaining a healthy weight and improving overall health.
5. Conclude: Based on the analysis, the action 'Drinking red wine instead of white wine' does not contribute to reducing cancer risk, making it the correct answer to the question.
