                  Notes: 1. Cervical cancer screening rate: the rate of women aged 30 and above who have received a screening for cervical cancer within
                         the past three years.
                       2. Breast cancer screening rate: the rate of women aged 45-69 who have received a screening for breast cancer within the past
                         two years.
                       3. Colorectal cancer screening rate: the rate of people aged 50-74 who have received a screening for colorectal cancer within the
                         past two years.
                       4. Oral cancer screening rate: since the screening for oral cancer focus primarily on smokers and betel quid chewers (including
                         those who quit) and the denominator already covers those with the habit of smoking and betel nut chewing, and as such, this
                         data will no longer be included starting from 2017 onward.
                       5. Lung cancer screening rate: the screening rate for lung cancer could not be estimated due to the unavailability of the population
                         base, thus no screening rate data is available.
                       6. Precancerous lesion: is a kind of benign (non-malignant) change in tissue type, however, the change has relatively high risk of
                         malignant disorder.
