Are genes responsible for prostate cancer? Latest genetic studies put forward that hereditary factors might be responsible for 5%-10% of the cancer. The risk rises in relatives of affected men. Men with a first degree relative with cancer of prostate hold a two to three fold rise in risk relative to the general population.
Genes are small individual groups of information in each cell of the human body. Each gene is made of a unique series of DNA. Researchers working on the Human Genome Project have approximated that there are as many as 30,000 different genes in every cell. Cancer starts when one or more genes in a cell are mutated, creating an abnormal protein or no protein in any way. The information given by an abnormal protein is different from that of a normal protein, which could lead to cells to develop uncontrollably and grow to be cancerous.
The majority cancer of prostate (around 75%) is deemed sporadic; indicating that the damage to the genes happens by possibility after a person is born. Familial prostate cancer is less common (around 20%) and happens due to a combination of shared genes and shared environmental or lifestyle factors. Hereditary (inherited) of the disease is rare (roughly 5%) and happens when gene mutations are passed in a family, from one generation to the next.
Latest advances in genetic research concentrate on genes connected to hereditary prostate cancer. Data from independent studies put forward proof for both an autosomal dominant pattern of inheritance and X-linked or autosomal recessive modes of inheritance. Males in families with X-linked or recessive modes of inheritance for the cancer hold a higher risk if they possess an affected brother(s) with cancer of prostate than if their father is affected.
