What causes cancer

The formation of cancer is the result of the combined action of multiple factors, which are usually closely related to gene mutations, environmental factors and lifestyle. Cancer refers to the uncontrolled growth and spread of certain cells in the body, gradually forming malignant tumors. This process mainly stems from gene mutations, which can be caused by external factors such as chemicals and radiation, or by genetic factors. Some gene mutations occur naturally, and with age, the probability of cell replication errors increases; external factors, such as smoking, excessive exposure to ultraviolet rays, unreasonable diet structure and lack of exercise, will increase the risk of gene mutations.

Smoking is an important factor in lung cancer, excessive drinking may be related to liver cancer, stomach cancer, etc., and excessive exposure to ultraviolet rays is also an important cause of skin cancer. In addition to the external environment, family inheritance also plays a key role; some people may be born with specific gene mutations that make them susceptible to certain cancers. Viral infections may also induce cancer, such as human papillomavirus (HPV) is related to cervical cancer.

In order to reduce the risk of cancer, it is particularly important to maintain a healthy lifestyle. It is recommended to quit smoking and limit alcohol consumption, pay attention to a balanced diet, eat more fruits and vegetables, increase the intake of fiber and antioxidants; exercise regularly and maintain a healthy weight. Sun protection measures can effectively reduce the risk of skin cancer. Vaccinations, such as HPV vaccines, can prevent certain cancers related to viral infections. If you suspect related symptoms or have a family history of cancer, you should seek medical attention in time for professional examinations and consultations.
