Is kidney cancer hereditary?

Is kidney cancer hereditary? The number of people suffering from cancer is increasing year by year. In many families, more than one person has cancer. People are worried about whether cancer is hereditary. In fact, cancer is not hereditary, but it has a tendency to be hereditary. If a pregnant woman has kidney cancer, please be cautious in preparing for pregnancy.

The so-called genetic predisposition to cancer refers to the tendency of some individuals to develop cancer more easily under the same conditions. Studies have shown that the incidence of common malignant tumors such as colorectal cancer, breast cancer, kidney cancer, prostate cancer, bladder cancer, kidney cancer, esophageal cancer, lung cancer, etc. has certain genetic factors, but the final occurrence of cancer, in addition to genetic factors, also depends on mental factors, environmental factors, dietary factors, lifestyle habits and other acquired factors. As the famous saying of traditional Chinese medicine goes, "congenital deficiency leads to acquired malnutrition."

The risk of first-degree relatives (parents or siblings) of kidney cancer patients getting kidney cancer is 2 to 3 times higher than the average population. Gynecological tumors also have a genetic tendency. I have treated a mother and a daughter with ovarian cancer while working in the tumor field. Therefore, people with a family history of tumors should pay more attention to the possibility of tumors and avoid the accumulation of related adverse factors.

Cancer is not a clear hereditary disease now, but there is increasing evidence that cancer does have a genetic tendency and is related to heredity. Now, there is more evidence about cancer heredity.

From the incidence of cancer in families to studies at the cellular and molecular levels, it is supported that cancer has a genetic tendency. This is because a genetic disorder unique to a cancer cell is observed in almost all cancer cells, which, from the perspective of cellular level analysis, shows that it can be inherited.

The material basis of heredity is genes. Among the genes in a normal human body, one type is called proto-oncogenes and the other type is called tumor suppressor genes. Proto-oncogenes can also be called oncogenes. If they mutate, they can cause genetic disorders and, under the influence of internal and external factors, turn normal cells into cancer cells. Tumor suppressor genes can inhibit and antagonize the functions and effects of oncogenes, or directly inhibit the growth of cancer cells, which is beneficial to the human body.

Therefore, the development of kidney cancer requires caution, and patients should go to the hospital for consultation in time.
