What is colorectal cancer?

Colorectal cancer originates along the lining of the colorectum, initially as a polyp, specifically an adenoma. If not removed, adenomas can develop into colorectal cancers. By screening, adenomas can be removed, preventing progression into colorectal cancers. Thus, screening can effectively reduce the risk of developing and dying from colorectal cancer

 

According to the most recent data from the Hong Kong Cancer Registry, colorectal cancer is now the most common cancer in the city, with more than 5000 new cases diagnosed in 2015. Colorectal cancer is also the second leading cause of cancer related deaths in Hong Kong, with over 2000 deaths in 2015.
