Cells normally grow and divide only when they are needed to keep our bodies functioning properly. But sometimes, the mechanisms that regulate cell growth stop working and cells divide out of control to form tumors. buy viagra in norway viagra without a doctor prescription buy cheap viagra canada viagra for sale fast shipping trusted on line sites to buy viagra generic viagra no prescription viagra australia no prescription cheapest viagra online discount viagra online This is called cancer. When cancer develops in the cells of breast or ovarian tissue it is called breast or ovarian cancer, respectively. Most people who develop breast or ovarian cancer have no history of the disease in their family. In fact, only 5 to 10 percent of all breast and ovarian cancers are caused by inherited genetic factors. These rare cases typically result from inherited mutations in either the brca1 or brca2 gene. The brca1 and brca2 genes are called tumor suppressor genes because they prevent uncontrolled cell growth. Brca1 is located on chromosome 17, and brca2 is located on chromosome 13. Scientists believe brca1 and brca2 work by fixing damaged or broken dna. Women who inherit a mutated copy of the brca1 or brca2 gene accumulate broken and deformed chromosomes, and therefore have a greater chance of accumulating mutations that will lead to uncontrolled cell growth and cancer. Men who inherit the defective genes are also more likely to develop breast and/or prostrate cancer. (yes, men can get breast cancer. ) how do you get breast or ovarian cancers? High-risk families include those who have inherited a mutation in either the brca1 or brca2 gene. The mutated brca1 and brca2 genes are inherited in an autosomal dominant pattern. A child only needs to inherit one copy of the mutated gene to have an increased cancer risk. Children who have a parent with the brca1 or brca2 mutation have a 50 percent chance of inheriting the mutation. Just because a person inherits the defective gene does not mean he or she will develop cancer, but inheritance greatly increases the risk. Out of every century women who inherit a mutated brca1 or brca2 gene, as many as 60 will develop breast cancer by age 50; by age 70, approximately 80 will develop breast cancer. How do doctors test for brca1 and brca2 mutations? A person with a strong family history of breast or ovarian cancer is a likely candidate for genetic screening. By analyzing a sample of the patient's blood, doctors can identify whether the person has inherited the brca1 or brca2 mutation..
