More than 25% of all cancers diagnosed in women are breast cancers. Between 2010 and 2014, about 1,856 women were diagnosed to have breast cancer in Singapore each year.
The risk of breast cancer increases with age. Most women who are diagnosed to have breast cancer are older than 40 years old, but younger women may also be affected.
Risk factors
A breast cancer risk factor is anything that makes it more likely you’ll get breast cancer. But having one or even several breast cancer risk factors doesn’t necessarily mean you’ll develop breast cancer. Many women who develop breast cancer have no known risk factors other than simply being women.
