1. What is prostate cancer and how common is it in the city?
The prostate is a gland roughly the size of a walnut situated in the male reproductive system between the base of the bladder and the urethra.
Prostate cancer can occur when abnormal genetic changes lead to the development of malignant tumours within the gland, with the potential to spread to other areas of the body, especially the bones and lymph nodes in the pelvic region.
According to the Hospital Authority, prostate cancer was the fourth most common in the city after lung, breast and colorectal cancer as of 2022, with 2,758 new cases recorded that year. It was also the third most common cancer in men.
Prostate cancer saw the highest rate of increase – 69 per cent – over a 10-year period from 2012. It accounted for 16 per cent of new cancer cases in Hong Kong men in 2022, with the median age of diagnosis at 71.
