Cancer has become a major killer of human health. Despite the rapid development of medical technology, the importance of cancer prevention cannot be overlooked. The following are the six widely recognized iron rules of cancer prevention throughout life, however, the first one is often overlooked by many people because it is not simple to practice.

1. Eat a balanced diet: The first iron rule is to stick to a healthy diet. The various vitamins, minerals, and fiber found in food help the body fight disease. But this rule stumps a lot of people because we need to make healthy choices in our fast-paced lives, stay away from too many greasy, high-sugar and processed foods, and eat more fresh fruits and vegetables and whole grains.

2. Regular physical examination: Early detection and early treatment are the key to cancer prevention and control. However, many people do not pay attention to this and ignore the importance of regular check-ups, especially for high-risk groups, such as those with a family history of cancer.

3. Keep moving: Exercise can improve immunity and reduce the risk of cancer. However, modern people often lack enough exercise due to work pressure and lifestyle habits, which undoubtedly increases the potential risk of cancer.

4. Avoid alcohol and tobacco: Tobacco and excessive alcohol consumption are major causes of many types of cancer. Quitting smoking and limiting alcohol may seem simple, but it actually requires strong willpower and long-term perseverance.

5. Managing stress: Long-term mental stress may lead to a weakened immune system and an increased risk of cancer. Learning to reduce stress and maintain a good mental state is also an important part of cancer prevention.

6. Develop a good work and rest: A regular work and rest helps the normal functioning of the body and improves the ability to resist diseases. But in this era of "staying up late culture", many people find it difficult to do this.

Cancer prevention is not achieved overnight, but requires us to consistently follow these six iron rules in our daily lives. The first one seems simple, but it actually requires us to have a deeper understanding of health and higher self-requirements. Only by truly integrating cancer prevention awareness into our lives can we better protect our health.
