Experts tell us that most cancers are not hereditary, but there are also some cancers that are caused by heredity, and colorectal cancer is the most common one.

Not everyone will get hereditary cancer. Seeing this, friends who have relatives with cancer must be worried, are they also at risk of getting the disease? In fact, it is not as everyone thinks. Experts tell us that there are two manifestations of familial cancer. One is that many people suffer from different cancers, and the other is that there is a certain cancer clustering phenomenon in a family. Although familial cancer can indicate that cancer is hereditary, it does not mean that everyone will inherit it. Therefore, it is the common living environment and living habits that make the family prone to the same cancer.
Although heredity is only one factor in cancer, some cancers are obviously hereditary. Experts point out that several cancers are most likely to be inherited, such as colon cancer, which is closely related to eating habits. If parents in a family suffer from colon cancer caused by multiple colon polyposis, their children are likely to suffer from the same type of cancer. Women whose mothers or sisters have suffered from breast cancer are three times more likely to develop breast cancer than ordinary women. For lung cancer, although environmental factors are the main cause of lung cancer, heredity also plays a role. Reports show that smokers whose close relatives suffer from lung cancer have a much higher risk of developing lung cancer than the average person.
