With a combined preparation, regulates the production of estrogen, was able to reduce the incidence of cancer-causing lung tumors in mice associated with exposure to tobacco.These data lead the new study."Therapy directed at reducing estrogen helped prevent breast cancer in some women," - he said in the news stories of the American Association for Cancer Research, Jill Siegfried, professor of Pharmacology and Chemical Biology of Cancer Institute at the University of Pittsburgh."If this therapy is effective, and lung cancer, it will make a big step in the development of medicine in this area, as these drugs can take a long period of time without harm to health, and other effective treatments for lung cancer is not been found", - he addsshe is.
In most cases, lung cancer estrogen receptor causes the tumor to grow when exposed to estrogen.Estrogen produces and aromatase enzyme in the lungs.Zidfrig and her colleagues found that blocking this receptor and aromatase enzyme can prevent development of estrogen-
«The findings could lead to new drugs that can reduce the risk of lung cancer in former smokers - said Siegfried.- Perhaps with the same drugs that help prevent breast cancer, we can fight with lung cancer patients in the past exposed to tobacco carcinogens.A lot of work in order to determine which category of patients will receive the most benefit from this treatment and the drugs themselves should be tested in clinical trials involving patients at risk. "The study results are promising.However, experts note that research involving animals often gives different results from studies involving people.
