Cancer
Cancer is defined as a group of diseases with aggressive cells that are characterized by their growth and unlimited division. These cells are spread to the surrounding healthy tissues, destroyed or transferred to distant tissues through a process called transference due to a range of factors that may be internal or external And it is possible to treat a good proportion of these cancers in the case of early detection, whether by surgical or radiological or chemical treatment, and in the lines of our next topic we will inform you about the relationship of genetics to cancer.
Cancer is hereditary
There are a number of clinical factors or some characteristics of the disease that appear significantly in cases of genetic cancer, and if one or more factors in a member of the family, then the doctor expects the emergence of genetic cancer, and the factors are as follows:
- The onset of the disease at an early age in individuals in the family. Breast cancer occurs at the age of 45 years, whereas in the non-genetic condition, the disease is only 3%.
- The appearance of more than one type of cancer in the same patient, and in this case a multiple cancer, and this type in the cases of genetic by 50 percent, and in non-genetic cases is only 3%.
Evidence that heredity caused cancer
Genetics is one of the most important factors that lead to cancer, according to studies and experiments on animals. Some families who suffer from some disorders and diseases have a greater chance of cancer than the colon, which leads to colon cancer. These tumors are later converted to colon cancer, which explains why members of this family carry cancer genes in their cells.
There are some urgent biochemical changes on the chromosomes that are associated with cancer. Some individuals develop various types of cancer, which are not linked to chemical changes, and here comes the role of genetic genes that carry the factors that cause cancer.
Genetics and skin cancer
Skin cancer occurs as a result of exposure to sunlight. Therefore, the darker the skin, the more resistant it is to the effect of radiation. A skin cancer called melanoma, which is destructive and closely related to genetic factors, is also associated with neuropathy. Or his children. This type is associated with the appearance of other cancers, such as brain cancer, eye nerves and ear, 10%.
Genetics and childhood cancer
There is a link between genetic factors and childhood cancer. Scientific experiments have shown that the risk of cancer in children with infected siblings increases. One of the most common types of children is eye cancer that affects the retina and leukemia.
Genetics and ovarian cancer
Genetic factors are closely related to women with ovarian cancer, especially if they have sisters of this type or mothers who are screened periodically, and it should be noted that it is better to remove the ovaries after the end of the fertility period in patients with this type.
