A general surgeon yesterday drew attention to gallbladder cancer, which, despite being less common than other cancers, has a relatively high mortality rate due to its often asymptomatic nature.
Citing statistics compiled by the Ministry of Health and Welfare, National Cheng Kung University Hospital’s Division of General Surgery director Chou Tsung-ching (周宗慶) said that in 2007, gallbladder cancer killed approximately 1,000 Taiwanese and was the 12th-most common cause of cancer-related deaths.
“Over the past year, the hospital diagnosed a total of only 10 patients with gallbladder cancer, which shows that this type of cancer is less prevalent, but extremely malignant,” Chou said.
Chou said the cancer is most common among females aged between 50 and 70, and is almost asymptomatic in the early stages, with primary risk factors including gallstones larger than 3cm.
Since symptoms such as jaundice, abnormal weight loss and pain often do not appear until the terminal stage, it is almost impossible for sufferers to detect and treat the illness early, Chou said.
Only a handful of such cancer cases were discovered at an early stage, Chou said, citing a 51-year-old woman who was diagnosed with the cancer after a health checkup caught a 3cm malignant gallbladder polyp last month.
“A previous health examination had found polyps and stones in her gallbladder, but the patient did not seek further monitoring. Fortunately, the malignant tumor was caught early and has not metastasized to her liver or regional lymph nodes. She is now in recovery,” Chou said.
Despite advances in medical technology, Chou said surgical removal of gallbladder tumors remains the only approach to treat the cancer.
“However, if the cancer has already reached terminal stages, it is much more complicated to remove the tumor and a patient is more susceptible to complications and poor postoperative outcomes,” Chou said, urging people in the high-risk group to regularly check their gallbladder or undergo a preventive cholecystectomy.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
An inauguration ceremony was held yesterday for the Danjiang Bridge, the world’s longest single-mast asymmetric cable-stayed bridge, ahead of its official opening to traffic on Tuesday, marking a major milestone after nearly three decades of planning and construction. At the ceremony in New Taipei City attended by President William Lai (賴清德), Premier Cho Jung-tai (卓榮泰), Minister of Transportation and Communications Chen Shih-kai (陳世凱) and New Taipei City Mayor Hou Yu-ih (侯友宜), the bridge was hailed as both an engineering landmark and a long-awaited regional transport link connecting Tamsui (淡水) and Bali (八里)
