New cancer cases in Hong Kong hit a new high in 2016, with colorectal cancer and lung cancer making up the top two types of the disease, according to official figures released on Tuesday.
Data from the Hospital Authority’s Hong Kong Cancer Registry (HKCaR) show that a total of 31,468 new cancer cases were diagnosed in the city during the year, marking a fresh annual peak.
The number was 1,150 more than that in 2015, translating to an increase of 3.8 percent, the Hong Kong Economic Journal reports.
Of the new cancer cases, 16,035 were diagnosed in males and 15,433 in females, up 4.3 and 3.3 percent from a year earlier, respectively.
A total of 14,209 people died of cancers in 2016, down 0.7 percent year on year, with more than half of the deaths being males (59%).
The crude annual mortality rates of cancer per 100,000 were 250.3 for males and 145.5 for females.
Among various types of cancers, the top three causing most deaths were lung cancer (26.6%), colorectal cancer (14.7%) and liver cancer (10.8%), with the three together accounting for over half of all cancer deaths.
Most of the increase in new cancer cases in 2016 was attributed to the growing numbers of lung and stomach cancers in men, breast and corpus uteri cancers in women, as well as colorectal and thyroid cancers in both genders.
As for the most common cancers, the top three were colorectum (17.3%), lung (15.7%) and breast (13.1%), which contributed roughly half of the cancer burden in Hong Kong in 2016, the HKCaR said.
The number of colorectal cancer cases rose by 8 percent in 2016 from a year ago to reach a historical high of 5,437.
As far as gender is concerned, the statistics show that colorectal cancer moved past lung cancer to claim the top spot of most common male cancer in Hong Kong for the first time.
For women, breast cancer remained at the top of the list, with the number of invasive breast cancer cases surpassing 4,100 for the first time as they rose 5.3 percent from a year earlier.
