Shanghai cancer rate is nation's highest: 350 per 100,000 people

SHANGHAI people's incidence of cancer is the highest in the nation, due to its large number of elderly and the persistence of unhealthy habits like smoking, Shanghai health officials said yesterday.

Cancer affects 350 out of every 100,000 people in the city on average, and the rate is growing by over 1 percent annually. Some 180,000 cancer patients live in the city.

Dr Wu Chunxiao, from the Shanghai Center for Disease Control and Prevention's tumor department, said cancer is becoming more common in the city because the population is aging, people are eating less healthy diets, leading more sedentary lives and smoking and drinking more.

"Age is closely related with the likelihood of catching cancer due to the elderly's weak immunity," he said.

Cancer is the second-most deadly disease for Shanghai residents, following cardiovascular disease. It was the cause of 31 percent of the disease-related deaths last year, said the annual health report released by Shanghai Health Bureau.

The top five cancers for males were lung, stomach, liver, colon and rectum.

The most prevalent cancers in women were breast, lung, stomach, colon and liver.

The incidence ratio between male and female was 1.2 to 1.

About 10.44 percent of local people older than 65 are likely to be diagnosed with cancer, a rate that increases to 21.31 percent for those over the age of 75, according to health officials.

Health authorities alerted women to the danger of breast cancer, whose incidence is now 1.65 times than that of 1980s.

About 3,800 women in Shanghai are diagnosed with breast cancer annually, and some 900 women die of it.

"Regular screening, early detection and early treatment are key to prevent and control breast cancer," said Dr Zheng Ying from Shanghai Center for Disease Control and Prevention.

"Three fourths of local breast cancer patients survive for five years or more, similar to the United States, thanks to the promotion of breast screening and public education," Zheng said.

More than 93 percent of local women being detected with breast cancer in the early stage can survive for over five years, according to doctors.
