Breast cancer is now the most common form of cancer in the world

According to the World Health Organization (WHO), breast cancer has overtaken lung cancer as the most common form of the disease, accounting for nearly 12% of new cases each year worldwide. Lung cancer was the most common type for the last two decades, but is now in second place, ahead of colorectal cancer, which is the third most widespread. 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 that 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.
