Colorectal cancer is the second most common cancer in Hong Kong. In 2019, Hong Kong recorded 5,566 colorectal cancer cases1, making it 15.8%1 of all cancer cancers. In the early stages of colorectal cancer, there may not have significant symptoms. According to the data from Centre for Health Protection, 49% of colorectal cancer diagnoses2 in 2017 were late-stage. This makes the cancer very difficult to treat. The risk of colorectal cancer increases significantly with age, however, colorectal cancer is considered the most preventable cancer. Detection of colorectal cancer screening can diagnose adenomas and colorectal cancer as well as increasing the recovery rate from colorectal cancer against patient.
The incidence rate of Nasopharyngeal Carcinoma (NPC) is remarkably high among Southeast Asia and Southern China regions, particularly Hong Kong. Therefore, it is also known as "Canton Tumor". Nasopharyngeal Carcinoma (NPC) does not have significant symptoms at preliminary stage, most of the patients would not be aware of the illness and have missed the optimal treatment period. In the early stage of Nasopharyngeal cancer, there are some similar symptoms with common cold, such as nose bleeding, headache, tinnitus, stuffiness, hearing loss, hoarseness and etc. It is reported that approximately 80% of the unscreened patients are in the advanced stage when the illness is diagnosed. There is no vaccine available against NPC at the moment, thus early screening will be the most effective means to raise early awareness, which could also increase the cure rate and survival rate.
