These 5 types of cancer are hereditary! If someone in your family has these cancers, you should pay attention

Whether I will get cancer is not only related to diet and environment, but also has a lot to do with our genetic inheritance. Napoleon, who is well known to everyone, his father, grandfather, 3 sisters and 4 brothers, as well as himself, all died of stomach cancer. A large amount of statistical data found that the most hereditary cancers are the following 6 categories: Epidemiological surveys have found that if a close relative has breast cancer, the risk of the disease in the offspring will increase by 1.5 to 3 times; if two close relatives have breast cancer, the incidence rate of the offspring will increase by 7 times. And the younger the age of the elders, the greater the risk of breast cancer in the offspring. Statistics show that about 10% of breast cancer patients have found that one of their close relatives has also had breast cancer.

Thyroid cancer: If there are more than 3 cases among close relatives, the probability of the offspring getting the disease is more than 90%

Statistical studies have found that if there are 3 or more patients among the first-degree relatives (parents, children, and siblings) in the family, the probability that the family has the disease is more than 94%.

About 5% to 10% of patients with medullary thyroid cancer have a clear family history of the disease.

Gastric cancer: 10% of gastric cancer is caused by genetics

The incidence of gastric cancer is very high in my country, and there is a phenomenon of familial clustering. The family incidence rate is 2 to 3 times higher than that of the general population.

According to oncologists, 5% to 10% of all gastric cancer patients have hereditary gastric cancer, which means that the cancer is inherited from their parents. Hereditary diffuse gastric cancer is an autosomal dominant genetic disease.

Liver cancer: obvious familial clustering

Liver cancer is also hereditary, which has been recognized by the medical community and confirmed at the genetic level. The most obvious clinical feature of hereditary susceptibility to liver cancer is family history, that is, if there are multiple liver cancer patients in several generations of the same family, the family's chance of developing liver cancer is higher than that of an ordinary family.

Lung cancer: Smoking + close relatives with lung cancer, the risk of lung cancer is 14 times higher

Lung cancer epidemiology reports show that if a person has a close relative with lung cancer and he smokes, his risk of developing lung cancer is 14 times higher than the average person.

Moreover, studies have confirmed that the heredity of lung cancer is more obvious in women. Among female patients with alveolar cell carcinoma, as high as 58.3% have a family history.

Although these six types of cancer are hereditary, it does not mean that people with a family history will definitely get cancer. Cancer is the result of a combination of factors such as lifestyle, external environment, and genetics.

However, for high-risk groups with a family history of genetic diseases, they should reduce external triggers and lower their chances of developing cancer.
