Breast cancer most common form
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.
Lung cancer was the most common type for the last two decades, but is now in second place, ahead of colorectal cancer.
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.
Obesity in women was a common risk factor in breast cancer, and is also driving overall cancer numbers.
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.
