Smoking is the number one cause of cancers in smokers but obesity is the main cause of cancers in non-smokers, according to a research study by British scientists. Non-smokers can prevent cancers by eating healthy diet and staying away from junk food. The research was funded by World Cancer Research fund and will be submitted at Royal society conference.
