According to data, breast cancer is the most typical cancer amongst women in China latest data from China National Cancer Registry. Data evaluation shows that in the years 2000–2013 the variety of cancers increased at a rate of roughly 3.5% per 12 months in comparison with a decline of 0.4% per 12 months during the same period in the USA.
The evaluation also shows that breast cancer rates are higher in urban areas of China than in rural areas. The higher the population density, the higher the rate. In small towns (lower than 500,000 inhabitants), the incidence of breast cancer is 30 per 100,000 inhabitants. For medium-sized cities (population from 500,000 to 1,000,000), it is 40 per 100,000 inhabitants. However, in large cities (over 1 million inhabitants), the incidence is 60 per 100,000 women.
As China’s economy developed rapidly, increasingly more people moved from rural areas and cities to large cities. As a result, many “megacities” have emerged. By 2014, there have been six megacities in China with populations over 10 million. It is very likely that urbanization has a serious impact on the incidence of breast cancer in China.
Here is a listing of some aspects which may be accountable for the increase in breast cancer rates in China:
Giving birth to children: Possession a couple of child lowers the risk of breast cancer. WITH single child policy in force since 1979, most ladies – especially in the event that they worked in the city – needed to strictly follow this policy to avoid punishment. Although the one-child policy was replaced by a two-child policy in 2015, the potential advantages on breast cancer rates are prone to 15 to twenty years to indicate.
Research also shows that girls who’ve their first child at 35 years or younger they sometimes have a protective effect against pregnancy. However, in China, many ladies have chosen to delay getting pregnant on account of work pressure and cultural changes.
Women are less prone to breastfeed than previous generations, which could also be one other factor. Studies have shown that each pregnancy and breastfeeding reduce a girl’s risk of cancer by reducing the variety of menstrual cycles over her lifetime. As a result, women are exposed to less estrogen. (Estrogen may stimulate the growth of breast cancer cells.) Same thing hypothetically that breast cells have to mature to supply milk, and mature cells are more proof against turning into cancer cells.
This was discovered by scientists from China memories between these “reproductive factors” – including oral contraceptives and hormone substitute therapy (HRT) – and the increase in breast cancer rates in China.

Stress: Stress – which is more prone to occur in large cities – has been linked to increased risk getting cancer. Although stress cannot directly cause cancer, it does affect the levels of assorted hormones and this suppresses the immune system. It is believed that when cancer develops, stress will help it progress.
Lifestyle: In modern China, women are generally less physically lively than in previous generations. AND test published in the International Journal of Behavioral Nutrition and Physical Activity show that physical activity levels amongst adults in China fell by almost half between 1991 and 2011, with women falling faster than men.
Unhealthy diets are also becoming more common in urban China, where fast food is on the rise. This led to increasing obesity amongst Chinese women.
Increased alcohol assumption has long been related to an increased risk of breast cancer ia Bulletin of the World Health Organization He notes that alcohol consumption is growing faster in China than in other parts of the world.

Aging: : Aging is the biggest risk factor for breast cancer. There are women they live longer in Chinawhich is fundamental factor on account of the increased incidence of breast cancer in the country. The older individuals are, the more genetic damage and less ability to repair damage.
Small improvements
Although the incidence of breast cancer amongst women in China is lower than in many developed countries, the rapid increase in the incidence of the disease – also observed in India – is of great concern.
Due to China’s large population, even a small percentage of improvement in cancer prevention could save a big number of ladies’s lives. There are many risk aspects that may be reduced by increasing cancer awareness and higher education about eating regimen, exercise, stress reduction, and improving breast cancer screening. Public health authorities in China can play a key role in developing well-defined strategies to handle this problem and reduce the burden of breast cancer in China.
