ABOUTNot three doctors would recommend e-cigarettes to smokers, with a quarter of them safe if they are safer than smoking, researchers say.
A survey of more than 500 cancer, doctors and nursing specialists revealed that more than half said they did not know enough about the issue to make recommendations to their patients.
This comes despite Public Health England (PHE) advice that indicates that devices are at least 95 percent less harmful than cigarettes.
The researchers asked the doctor whether they would recommend e-cigarettes to patients who continued to smoke after diagnosis.
Smoking increases the risk of complications of treatment, the onset of disease, and the development of further tumors, increasing the risk of death.
The study showed that 29 percent of health workers say they do not recommend patients transferred to e-cigarettes, while 25 percent did not know if they were safer than smoking.
The researchers said that health workers needed more training to help them better counseling patients.
A new study, presented at the National Conference of the Glasgow Research Institute in Glasgow in 2018, found that most respondents either did not know if their hospital had any guidelines on the issue or thought they were not.
Lead researcher Dr. Jo Brett of Oakford University said: "Smoking is a well-established risk factor for many common types of cancer. This is the largest possible cause of cancer in the world.
