8 leading factors leading to cancer

Smoking, drinking alcohol, obesity, poor nutrition, unsafe sex, lack of exercise, air pollution and low consumption of fruits and vegetables are factors that lead to cancer, but it is possible preventable.

The World Health Organization recommends that you eat at least 5 fruit meals a day to prevent cancer. "One- third of cancer deaths can be avoided if exposure to these risks is reduced. Prevention is still the best method. It is much more effective than applying medical technology. "Dr. Majid Ezzati, Harvard University said. It is estimated that up to 7 million cancer deaths worldwide each year are caused by 12 types of cancer. Ezzati's research is contributed by more than 100 scientists around the world for medical data and evidence.

Smoking is considered the biggest factor, involving 5 types of cancer: lung, mouth, stomach, pancreas and bladder. " Of the 2.43 million people who died of cancer in 2001, 37% were lung cancer ," Ezzati cited. Smoking is increasing in developing countries in recent decades, so experts predict that the number of cancer deaths will increase in the coming years. Behind tobacco is alcohol and food shortages.

Obesity contributes to colon and breast cancer, mostly concentrated in developed countries.

Unsafe sexually transmitted human papilloma virus (HPV) causes cervical cancer in sub-Saharan African women and parts of Asia. Death from this type of cancer is also mainly due to lack of diagnostic equipment and clinical testing services.

Urban air pollution is considered a carcinogen in the west and south of Asia, while smoke from indoor coal burning is a problem in China.

Dr. Ezzati also reported the spread of hepatitis, related to liver cancer, in part because of the use of infected leaks at poor medical centers.
