Which four kinds of women are prone to cancer is too absolute. Generally speaking, people with family history, poor living habits and unhealthy sex life are prone to cancer. 1. Family history: An important reason for the occurrence of cancer is heredity. For example, breast cancer, ovarian cancer and endometrial cancer, which are highly prevalent among women, are all related to heredity to a certain extent. Therefore, people with family history should pay attention to regular medical checkups. 2. Poor living habits: Cancer occurs due to a combination of internal and external factors. When there are poor living habits such as little exercise, staying up late, irregular diet or work and rest, smoking, alcoholism, etc., the risk of cancer can be increased. 3. Unhealthy sex life: cervical cancer is directly related to sex life. Women who have sex earlier, have unclean sex and have more sexual partners are the group with high incidence of cervical cancer. It is recommended that this group of people should have regular medical checkups to detect and treat the disease at an early stage to avoid its progress.
