Nutrition plays a vital role in cancer prevention and can influence the effectiveness of cancer screening. A balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help maintain a healthy weight and reduce cancer risk. Some studies suggest that certain foods might even improve the body's response to screening and treatment. The NHS encourages individuals to adopt a healthy lifestyle, which includes a nutritious diet, as part of an overall strategy for reducing cancer risk. Consulting a dietitian can provide personalized guidance tailored to your health needs.
