Is cancer inherited?


Is cancer transmitted by inheritance?</a>

Recently, cancer has become one of the most frequentCauses, causing death of a person. If family members in connection with oncology one by one die, sooner or later the question arises about the hereditary nature of this disease.

However, there is no unequivocal answer to this question.

Causes of cancer

In principle, cancer can happen in everyoneA person, regardless of his age, sex, race, financial status and attitude to his own health. There are cases when babies were born with an intrauterine malignant tumor, although it would seem that in this period the baby is protected from negative influences on the body as much as possible. And there is no single reason for oncology. The only opinion on which scientists agreed that at some point in the body there is a malfunction that causes a change in the genetic material, as a result of which the cells begin to share uncontrollably, killing their host as a result.

There are special genetic tests that can identify a person's predisposition to a particular type of cancer.

Heredity of breast cancer

In some families, oncology occurs more often thanIn others. Therefore it is no wonder that members of these families start to wonder if they have a predisposition to cancer, while some panic, they can develop a real carcinophobia.
Indeed, not so long ago scientists have been singled outGenes that can cause breast, ovarian, and colon cancer. These genes are present in every person, but only in some they are modified so that the risk of developing an oncology rises many times. A feature of inherited cancer is the occurrence of it at the age of 30-50 years and earlier. For example, if the family knows more than 2 cases of breast cancer up to 50 years, at least 1 case up to 35 years old, or someone was struck by both breasts at the same time, it is safe to say that members of this family have a hereditary predisposition to that species Cancer. There is a medical opinion that breast cancer is closely related to ovarian cancer, so the above examples are true for both of them.

Even if a person does not have a hereditary predisposition to a particular kind of cancer, there is no garantia that he will never get them.

Heredity of colon cancer

Also, colon cancer is quite commonIs inherited. Two of its types are known: family adenomatous polyposis and inherited colon cancer syndrome. If the family has already met at least one of these types of oncology, all members of this family need to undergo a regular examination, capable of detecting the disease at an early stage - a colonoscopy. Especially should be alerted to people in families who know of two cases of the onset of such cancer before age 50 or if several relatives have been identified numerous examples of the formation of polyps in the intestine.
