Every cigarette you smoke shortens life by almost 6 seconds

People in developing countries - 14 cigarettes. In a typical cigarette contains 9.8 milligrams of nicotine in cigarettes - 100-200 mg. In five cigarettes contain nicotine, enough to kill a person. But with every cigarette smokers smoked really gets 1.2 milligrams, or the rest of the nicotine is burned remains of cigarette butts. In cigarettes also contain other toxic substances such as arsenic, cyanide and polonium. In tobacco smoke contains more than 50 chemicals, 11 of which are known to dangerous carcinogens. According to the Centers for Disease Control and Prevention say SShACenters for Disease Control and Prevention, the average smoker lives for 13-14 years less than Non smoking. For any person who has died from the effects of smoking, smoking for 20 suffering from serious diseases, the cause is smoking. Every cigarette you smoke reduces life expectancy by 5 minutes and 30 seconds.

Found a new method of chemotherapy previously treatable forms of breast and ovarian cancer

Scientists have found a genetic mechanism that allows for resistant forms of breast and ovarian cancer in people with the defective gene BRCA2 treatment, reports the BBC. The study was published in the journal Nature. There is a tendency to improve the diagnosis and treatment of cancer, however, many tumors develop resistance to the drugs. During the treatment of cancer, unfortunately, a number of side effects, which can cause damage to cellular DNA. Created in a faulty dyudey BRCA2 gene cells initially not in a position to restore the damaged DNA. Can mutate these cells to a malignant tumor. An academic medicine (PARP inhibitors, platinum chemotherapy) were. Most effective in the treatment of tumors with a defective BRCA2 gene in the early stages of the laboratory tests The main part of the test substance is for breast cancer and ovarian cancer conducted. But there is a problem, some of the tumors develop resistance to treatment because of the inability of cells with damaged DNA to recover. However, the last phase of the study showed that some of the cells with damaged DNA can mutate under the influence of the above medications, BRCA2 gene back to normal, so that damage to DNA is prevented and the cells can be returned to normal. Unfortunately it is not possible to neutralize the entire tumor, but it is possible to neutralize the adverse effects of drugs, to DNA damage, which, as

5% of the incorrect data, scientists have found sites about breast cancer

Five percent of the pages that discuss breast cancer contain erroneous information and self-help alternative treatments that may result in serious negative consequences, U.S. researchers reported. "We recommend that you be skeptical of information on the Internet about this problem, since the information obtained via the Internet, should be of exploratory nature, and not as a guide to self-healing", - said the head of the study, Dr. Meric-Bernstam . Most people find information online, using search engines, no medical facilities, and most are not going to find on the first page of results, the researchers reported the journal Cancer. Scientists have identified the 5 most popular search engines on pages that seem to meet. They have examined 343 web page. The researchers found that every 20-th page contain inaccuracies or errors. 41 also failed statement found on 18 pages. This represents about 5.2% of the sites. By Meric-Bernstam, patients with breast cancer often physicians competent, which is a very positive development came, but there are those who read about the treatment after the time not to appeal to clinicians and exposed their health at great risk, because such self to-use treatment methods of alternative medicine.
