The average age of women in Shanghai with breast cancer rose to 57 in 2013, according to research conducted by the Shanghai Center for Disease Control and Prevention. The average age in 1973 was 54.
Officials added that while there’s a common misconception that more young people are getting breast cancer than older people in Shanghai, the incidence among women over 40 is the highest, according to Shanghai Daily.
According to the study, women between 50 and 59 years old were in the highest- risk group, nearly 23 percent higher than those who were between 40 and 49.
The 30-39 age group showed a 3 percent annual decrease in the incidence of breast cancer rates since 1995. The incidence rate for the 20-29 age group remained unchanged.
Considering the city’s aging population factor, the standardized incidence rate of breast cancer among Shanghai women is 17 percent lower than world average and half that in developed countries.
Figures released by the the same center last month showed that around two percent of females in Shanghai have been diagnosed with cancer, breast cancer being one of the most common types.
The statistics also showed that almost one in 60 Shanghai residents has been diagnosed with cancer, placing the city among areas with the highest rates of cancer in China.
Lung cancer remains one of the most common forms among men in the city, with about 1.5 percent of Shanghai men been having been diagnosed. The center found that smokers were ten times more likely to develop lung cancer than those who don’t smoke.
As for breast cancer; age, heredity, early age of menstruation and late menopause are widely considered the main contributors to the disease, and around 70 to 80 percent of female patients with breast cancer didn’t have a family history of it.
