LUNG cancer has been the No. 1 killer of all cancers in Shanghai for decades, the city chronic disease control center said yesterday.
Most lung cancer patients, 67 percent of whom were male, were aged between 65 and 70 and it was rare to see lung cancer patients under the age of 35.
In 2009, 1,178 people were diagnosed with the disease, accounting for about 12 percent of the total new cancers reported last year and nearly 20 percent more than 2008, said Feng Tiejian, vice president of the center.
The cancer rate had increased by 10 to 30 percent every year in Shanghai over the past few years and more young patients were being diagnosed with cancer, Feng said.
The sharp increase was mainly due to an increase in the number of senior citizens living in the city, while smoking and air pollution were other key factors.
The city reported 9,822 new cases of malignant tumor in 2009, an increase of 13.3 percent over the previous year.
A total of 1,533 patients died of malignant tumors in 2009, accounting for one quarter of the deaths caused by diseases.
More than 8,750 people died of cancer between 2001 and 2009 and the number is expected to reach 10,000 in 2010. Cancer is the No. 1 killer in Shanghai.
The age of cancer patients has also been falling. Most patients with cervical cancer were middle-aged women in the past, but there had been an increasing number of women under the age of 20 diagnosed with the disease in recent years.
