Anti-estrogen medication reduces risk of dying from lung cancer, study finds

February 18th, 2011

Between 5 and 10 percent of breast cancer cases are hereditary, arising because the patient inherits from the father or mother a mutation in a gene that is susceptible to causing the illness. BRCA1 and BRCA2 have already been identified as two of the genes to be monitored. It is estimated that 30 percent of hereditary breast cancer cases are due to mutations in one of these two genes (which suggests, at the same time, that there are other genes involved, but exactly how is still unknown). In any case, few of the mutations found in BRCA1 and BRCA2 could be clearly identified as pathological. The fact is that the mutations found were numerous; their variation even depending on the population.
