The number of cases rose to 79.6, and colorectal cancer cases in Hong Kong accounted for 15.3% of all new cancers in 2021.

The Department of Health pointed out that multiple epidemiological studies have shown that obesity increases the risk of colorectal cancer, and the risk of colorectal cancer is increased by 42% compared with those of normal weight (the risk of colon cancer and rectal cancer are increased by 53% and 20% respectively). Among colorectal cancer patients in Hong Kong, more than half of the colorectal cancer cases (51.3%) were at an advanced stage when diagnosed, that is, the cancer cells have spread to nearby lymph nodes (stage 3: 26.9%), or have further metastasized to other parts of the body (stage 4) :24.4%).
The Department of Health found in the 2020-2022 Population Health Survey that among non-institutionalized persons aged 15 to 84, more than 30% are obese, and more than 20% are overweight. If broken down by age, the 45 to 54-year-old group has the highest rate of obesity or overweight. The agency cited a South Korean study that followed more than 3.3 million people aged 20 to 49 and found that those with persistent obesity or central obesity increased their risk of early-onset colorectal cancer by 9% and 18% respectively, while those with persistent obesity and persistent central obesity increased their risk of early-onset colorectal cancer by 9% and 18% respectively. The risk of early-onset colorectal cancer is 19% higher. Therefore, Hong Kong people are advised to maintain good living habits, avoid obesity, and undergo regular check-ups.
