Is cancer hereditary? What types are there

Don’t think that cancer is not hereditary. According to current research, many families have a history of cancer inheritance, but gene mutations cannot be ruled out. It depends on whether the family has it. If the father and brothers of the family all have cancer, then the chance of inheritance is almost as high as 80%. It cannot be ruled out that it is due to gene mutations during conception, so the spread and prevention of cancer must be done well.

Is cancer hereditary?

It is generally believed that hereditary tumors account for only 1%-3% of all human tumors, and only a few malignant tumors have a family genetic background. In these hereditary tumor families, the parents of the previous generation can pass on the mutated genes that cause tumors to the next generation of children. However, it should be emphasized that for hereditary malignant tumors, the mutated genes carried by children only mean that the risk and possibility of developing tumors are increased, and it does not mean that they are already carrying the tumor disease itself. Therefore, people with a family history of cancer do not necessarily develop cancer.

Studies have shown that the occurrence of tumors is the result of long-term interaction between genes in the body and many external environmental factors. People with a family history of cancer must pay attention to cancer prevention. Not only should we strengthen self-care, maintain emotional stability, balance diet and nutrition, get adequate sleep, exercise moderately, pay attention to the combination of work and rest, and change bad habits such as smoking and drinking, but we should also consider choices in marriage, childbirth, work environment, etc., and try to avoid the influence of harmful rays and toxins in the environment. At the same time, we must insist on regular health examinations and genetic counseling to keep abreast of the risks of cancer and prevention measures for ourselves and the next generation. We should strive to achieve early detection, early diagnosis and early treatment, so as to effectively reduce the incidence and mortality of cancer.

So which cancers with a genetic basis require increased vigilance and prevention?

Liver cancer-Children are the primary prevention targets:

If parents are diagnosed with liver cancer, their children can be the primary prevention targets because vertical transmission of the hepatitis B virus can easily cause a familial clustering of liver cancer. In my country, most liver cancer patients are caused by hepatitis B. In particular, offspring of mothers who are carriers of the hepatitis B virus have a higher risk of developing liver cancer. Therefore, if there is a liver cancer patient in the family, it is recommended that their children immediately undergo a comprehensive liver examination, including five hepatitis B tests and liver B-ultrasound. If you are found to have hepatitis B, you should actively cooperate with the doctor and undergo antiviral treatment, liver protection treatment, etc.; if you do not have hepatitis B, you should have regular physical examinations and prevent cancer scientifically.

Breast cancer-If the mother gets cancer before menopause, the daughter is at great risk:

If there is a breast cancer patient in the family, their children and relatives should also have their breasts checked because breast cancer has a clear genetic tendency. Generally speaking, if the mother has breast cancer, the daughter's chance of getting breast cancer is 2 to 3 times higher than other women. Here’s a way to determine whether you have a genetic predisposition to breast cancer: if your mother or sister had breast cancer before menopause, you are more likely to get breast cancer. If your mother was older when she was diagnosed with breast cancer and she is the only one in your family who has had breast cancer, you don't need to worry too much. Breast self-examination is a compulsory course for all women, in addition to: B-ultrasound, mammography, etc. In addition, it is recommended that women with a family history should give birth early (before the age of 30) and breastfeed, and that menopausal women should not indiscriminately use estrogen-containing drugs to minimize the risk factors of breast cancer and reduce its incidence.

Intestinal cancer-the hidden danger of cancerous intestinal polyposis:

Under normal circumstances, intestinal polyps do not cause any harm to the human body. However, familial colon polyposis, that is, multiple adenomatous polyps growing in the colon, have a high tendency to become malignant and can easily cause colon, rectal and duodenal tumors. Familial colon polyposis has a clear familial clustering. Therefore, if you want to avoid "inherited" colon cancer, you should first check whether there are any relatives in your family who have colon polyposis. The descendants of such patients should undergo colonoscopy early and should do it every year. It should be noted that the disease has a tendency to be inherited from one generation to the next, which means that if the parents are not sick, it does not mean that the children will not be sick.
