Which five kinds of people are destined to get cancer before they die is too absolute. People with family history, poor living habits, occupational factors, unhealthy sex life and other people are at risk of cancer. 1. Family history: One of the important factors of cancer is genetic susceptibility, therefore, people with family history will increase the risk of cancer. Therefore, people with a family history of cancer will have a higher risk of developing cancer. Therefore, they should have regular medical checkups to detect cancer at an early stage. 2. Poor living habits: many cancers are related to poor living habits, such as less fiber diet, sedentary lifestyle, which may lead to intestinal cancer; eating too hot food, which may lead to esophageal cancer; smoking, which may lead to lung cancer. 3. Occupational factors: Long-term exposure to carcinogens in some occupations can easily lead to certain cancers. For example, paint factory workers can easily lead to leukemia; asbestos factory workers can easily lead to lung cancer. 4. Unhealthy sex life: For example, cervical cancer, which is highly prevalent among women, is related to unclean sex, early sex and multiple sexual partners. It is suggested that high-risk groups should have regular medical checkups, maintain good living habits and exercise properly to reduce the probability of cancer.
