Study shows smoking can cause genetic damages

A recent Finding on the effects of smoking indicates that smoking tobacco can be harmful to DNA and cause permanent genetic damages in few minutes.

Inhaling Cigarettes also increases immediate risk for lung cancer.

Stephen S. Hecht, the author of the research stated that the findings would serve as an alarm to those who are tempted to smoke cigarettes. Hecht works at the University of Minnesota in Minneapolis in Masonic Cancer Center and department of pharmacology. His statement published in American Chemical Society’s new edition.

During research, cancer-causing factors were found in cigarette smoke that is known as polycyclic aromatic hydrocarbons, or PAHs.

PAHs cause a permanent harm on DNA raising chances of lung cancer. More than 3,000 people die every day all over the world due to lung cancer. It is yet not confirmed in the research how PAH factor damages the DNA molecules.

The researchers based their observations by tracking a PAH in 12 smokers’ bodies. All of them were already habituated of smoking.

The objective behind this research was to see the impact of PAH on human metabolism with an assumption that the PAH have been inhaled only by smoking and not by any other means, air pollution or consumption of any food item. The research showed that the particular PAH under observation—phenanthrene converted into toxin very fast and started affecting DNA within 15 to 30 minutes in an adverse manner.

Aspirin for Cancer Treatment?

Aspirin DrugA study involving more 25,570 people suggests that Aspirin could reduce the risk of cancer on human beings. The research is published in The Lancet on Dec. 7.

Hundreds of thousands of elderly people take a low-dose aspirin to lower their risk of cardiovascular disease or heart attack. Now a study suggests that this daily preventive dose of aspirin could be staving off cancer too. During the study, people were given 75 mg to 100 mg of aspirin per day. The results show that patients who took aspirin regularly for several years were 20% less likely to suffer from solid tumor cancers of the stomach and lung.

However cancer experts and doctors are not yet prescribing aspirin for cancer patients. According to a cancer expert more research is needed on the effectiveness of aspirin for cancer treatment and its side effects before the doctors can safely prescribe the drug.

Cancer Risks of Blood Pressure Drugs

United States: On Sunday a team of US researchers said that some of the most commonly used blood pressure drugs may slightly increase the risk of cancer. Tests done on patients using the Blood Pressure drugs showed a 1.2% increase in Cancer compared to those who didn’t take the drugs.
Though this is small number and may not cause an alarm among the doctors and patients the test results are significant.
Almost 86% of the patients in the trials took Micardis (German drugmaker Boehringer Ingelheim’s telmisartan) which has annual sales of more than $1.5 billion worldwide.

Martin Ledwick, head information nurse at Cancer Research UK, said in a statement that at the moment there isn’t enough evidence to draw any firm conclusions about how blood pressure drugs might affect cancer risk and the test results will need further investigation.
