Earlier researches have shown that lifestyle and environment determines a person's risk of developing many types of cancer. Recent study showed that presence of a particular kind of genes increase the risk of developing five different types of cancer - skin, lung, bladder, prostate and cervical cancer.

Previous studies have shown that smoking and drinking increase risk of various cancer like lung cancer and liver cancer.

Researchers believe that presence of this particular gene along with unhealthy lifestyle increases a person's vulnerability to many cancers while its absence put others at the lower risk despite of smoking, drinking and poor diet.

Researchers isolated the genes by looking at the genetic make up of more than 33,000 cancer survivors and another 45,000 people who had never suffered from the disease. The genes were studied in accordance with their carrier's lifestyle and history of the disease.

Tim Bishop, professor of genetic epidemiology at the University of Leeds said that cancer was often caused by a "complex" interplay between genetic and environmental factors, and that these newly identified genes could go some way to explaining their relationship.
