乳腺癌成最常见癌症

Breast cancer has overtaken lung cancer as the most common form of the disease, accounting for nearly 12% of new cases each year worldwide, the World Health Organization said on Tuesday. An estimated 2.3 million new cases of breast cancer were diagnosed last year.

世界卫生组织2月2日表示，乳腺癌已经超过肺癌，成为全球最常见的癌症。去年乳腺癌新增病例230万，占全球癌症新增病例的12%。

Lung cancer was the most common type for the last two decades, but is now in second place, ahead of colorectal cancer.

在过去20年最常见的肺癌退居第二，直肠癌排第三。

As the global population grows and life expectancy increases, cancer is expected to become more common, rising to about 30 million new cases per year in 2040 from 19.3 million in 2020.

随着全球人口不断增长和预期寿命延长，癌症将变得更加普遍。2020年全球有1930万癌症病例，预计这一数字将在2040年增至3000万例。

Obesity in women was a common risk factor in breast cancer, and is also driving overall cancer numbers.

肥胖是导致女性罹患乳腺癌的常见风险因素之一，也导致了全球癌症病例的增加。

The WHO, warning against risk factors, said around one-third of deaths from cancer are due to tobacco use, high body mass index, low fruit and vegetable intake, lack of physical activity and alcohol use.

世界卫生组织在提醒人们注意危险因素时称，大约1/3的癌症死亡原因为吸烟、肥胖、水果和蔬菜摄入量低、缺乏体育锻炼及酗酒。
