In a breakthrough discovery, scientists have, after extensive research, managed to map the DNA patterns of two of the deadliest cancer forms, a revelation that could lead to revolutionizing of the treatment and prevention methods of these cancer forms.
The large-scale project was led by British researchers and exposed mutations of DNA that cause both mouth and lung cancer, and it has been revealed that it takes a mere 15 cigarettes for the human gene mutation to start.
British scientists have created a "transforming moment" by cracking the genetic code of a couple of very deadly cancers. These scientists have made a breakthrough discovery through the identification of the mutations in a form that have never been seen before.
After a long research, the researchers have gathered proof from studies and have completely mapped the genetic codes that are the reason for lung and skin cancer.
Scotland's Chief Medical Officer Harry Burns has, after much analysis, revealed that men are now "narrowing" the gap of life expectancy with women as they are currently more likely to adopt a healthier lifestyle.

After extensive research, scientists have managed to discover a gene linked to schizophrenia and bipolar disorder, a breakthrough discovery which could, according to the researchers, help in identifying and treating the mental disorders much earlier.
The gene ABCA13 has been discovered by an international team of scientists, led by Queensland Institute of Medical Research and University of Edinburgh, and it has been shared that the gene is active in the "hippocampus and cortex regions of the brain".
A new study has revealed that pregnant women can read signs of anger or aggression on someone's face more accurately as compared to men and females who are not pregnant, all thanks to the raging hormones.
It has been previously revealed that during certain phases of the menstrual cycle, women are able to better read emotions on people's faces, on the back of a peak in levels of progesterone, the female hormone. Now it has been established that the same can be true for pregnant women as well.
Official figures shared have revealed that the rate of breast cancer death around Wales is lower than that for UK, overall, and the screening program in the former also boasts more specific and higher detection rate.
For Wales, the death rate from breast cancer stands at 26.66 per 100,000 populations, as opposed to UK's figure of 26.71 per 100,000 women. Also, Breast Test Wales has the highest detection rate, with 124.4 per 100,000.
Since 2000, BreastCheck has been providing breast cancer screening to women all across the country, and latest figures shared by the agency reveal that for the year 2008 and early 2009, as many as 672 women were diagnosed with breast cancer, which mean 7.3 cancers were discovered per 1,000 women screened, a rise from the 6 cancer per 1,000 women figure shared for 2007.
