The incidence of breast cancer has overall increased in Singapore. About four women every day are diagnosed with breast cancer, making it the most common cancer among women. Early detection is vital in the successful treatment of breast cancer thus, increasing the chances of survival. Women above the age of 50 should go for a breast screening once every two years, and those between the ages of 40 and 49 should consider an annual screening. Mammogram and ultrasound diagnostic tools are commonly used to detect breast cancer.
However, mammogram is the primary screening tool for women who display no signs or symptoms of the disease. Regularly scheduled mammogram screenings and breast examinations can detect breast cancer in its earliest stage for some women who are at risk for developing the disease. The type of breast cancer diagnosed at this stage is also known as Ductal Carcinoma in Situ (DCIS), a non-invasive cancer that has not spread past the layer of tissue where it began.
