Is Breast Cancer Genetic?

If a large amount of research has been done on the causes of breast cancer, a detailed breakdown, by percentage, or such action is not quite right. hormone levels and levels of factors associated with age. Nutrition and heredity are among the most important indicators of the likelihood of breast cancer. These hormones are estrogen and progesterone. Each layer is different from the average of women in the age of the woman, which increases the likelihood of developing breast cancer. These factors include age of onset of menstrual age and the age of completion. If a girl begins menstruation at an early age, or past middle-aged woman is not reached menopause, increases the risk of cancer. Because of this connection is a hormone therapy after menopause is not always a recommended practice – especially if it is a family story with links to breast cancer. The food aspect was also under control, but all indicators show that overweight and / or consumed a diet rich in calories as fat, are both positive and related to a higher probability of breast cancer. There is also evidence that excessive consumption of alcohol plays a major role. Whether the breast cancer gene actually two questions. A family is whether genetics is a factor, and the other is the genetic cause of relapse in patients effectively. Like the latter, a woman who previously breast cancer was successfully removed still a very significant higher than you are again. A tumor surgically removed at an early stage is the best chance to reduce future risks. Chemotherapy and radiotherapy are not as effective as cancer stem cells are never destroyed. Stem cells are specialized cells to multiply and replace old cells. So, if the cancer stem cells, even in small quantities are still present, is their genetic code in certain cells of the body, which replaces the old cells are replicated. Family genetic factors are certainly involved, although most researchers believe that genetic inheritance is not the main cause of cancer. It is a question of risk, but a small percentage of the population carries the code quite defective gene that causes the disease. It is now estimated that approximately 50-10% of hereditary breast cancers by genetic mutations can cause. It is certainly an increased risk of a person whose mother or sister has had breast cancer, especially if at an early age (before menopause has occurred). The research has two specific genes, the direct causes of breast cancer have been identified. In addition, the presence of oncogenes (cancer-causing mutations in a general) in the development of the cause breast cancer, and any other form of cancer that can afflict us.
