The Health Promotion Administration (HPA) yesterday said that 531 people were diagnosed with lung cancer in a government-funded screening program that began last year.
The Ministry of Health and Welfare on July 1 last year added lung cancer to the government-funded routine cancer screening program for adults, providing a free low-dose computed tomography (LDCT) scan every two years to high-risk individuals.
Eligibility covers men aged 50 to 74 and women aged 45 to 74 with a family history of lung cancer; and heavy smokers aged 50 to 74 who have been smoking for 30 pack-years (the average daily pack of cigarettes times years of smoking) and are willing to quit smoking or have quit less than 15 years earlier.

HPA Cancer Prevention and Control Division Director Lin Li-ju (林莉茹) said that 49,508 people received LDCT scans for lung cancer, resulting in 531 positive results, 85.1 percent of whom were detected at an early stage.
Of the 531 people, 396 have a family history of lung cancer, 118 are heavy smokers and 17 are heavy smokers with a family history of lung cancer, she said.
Lung cancer is the leading cause of cancer-related deaths worldwide, the HPA said.
The mortality rate of lung cancer in Taiwan was 21.8 deaths per 100,000 people last year, a decrease of 16.2 percent compared with 26 deaths per 100,000 people in 2011, but it is still the leading cause of cancer deaths in Taiwan, accounting for 19.4 percent of all cancer deaths last year, the agency said.
Taiwan Lung Cancer Society chairperson Yang Cheng-ta (楊政達) said the high mortality rate is mainly caused by the disease usually having no symptoms in the early stages.
By the time people develop symptoms such as chest pain, breathlessness and coughing up blood, the cancer has already progressed to advanced stages, Yang said.
The five-year survival rate of early stage lung cancer can be above 90 percent, but if it is diagnosed at stage 4, the survival rate can drop to 10 percent, he said.
More people with a family history of lung cancer were diagnosed at earlier stages than people who are heavy smokers, because those with a family history have seen their family members fight cancer and gained awareness of the disease, while many heavy smokers know the increased risk from smoking, but are less willing to face it, he added.
According to the Taiwan cancer registry in 2020, among every two new lung cancer cases, one was diagnosed with stage 4 lung cancer, and more than 60 percent of those were detected at an advanced stage, the HPA said.
HPA Director-General Wu Chao-chun (吳昭軍) said LDCT is the only internationally recognized screening tool for the early detection of lung cancer.
Eligible recipients should undergo testing as soon as possible to increase the chance of early detection and boost their survival rate, Wu said.
Minister of Health and Welfare Hsueh Jui-yuan (薛瑞元) said that about 500,000 people in Taiwan are eligible for LDCT screening, but only about 50,000 underwent testing over the past year.
He urged eligible recipients to make use of the government-funded screening test, saying that early detection of cancer greatly increases the chances for effective treatment and survival.
Early detection also presents a smaller financial burden than costlier treatments and a better quality of life, he added.
Taiwan is stepping up plans to create self-sufficient supply chains for combat drones and increase foreign orders from the US to counter China’s numerical superiority, a defense official said on Saturday. Commenting on condition of anonymity, the official said the nation’s armed forces are in agreement with US Admiral Samuel Paparo’s assessment that Taiwan’s military must be prepared to turn the nation’s waters into a “hellscape” for the Chinese People’s Liberation Army (PLA). Paparo, the commander of the US Indo-Pacific Command, reiterated the concept during a Congressional hearing in Washington on Wednesday. He first coined the term in a security conference last
Prosecutors today declined to say who was questioned regarding alleged forgery on petitions to recall Democratic Progressive Party (DPP) legislators, after Chinese-language media earlier reported that members of the Chinese Nationalist Party (KMT) Youth League were brought in for questioning. The Ministry of Justice Investigation Bureau confirmed that two people had been questioned, but did not disclose any further information about the ongoing investigation. KMT Youth League members Lee Hsiao-liang (李孝亮) and Liu Szu-yin (劉思吟) — who are leading the effort to recall DPP caucus chief executive Rosalia Wu (吳思瑤) and Legislator Wu Pei-yi (吳沛憶) — both posted on Facebook saying: “I
Sung Chien-liang (宋建樑), who led efforts to recall Democratic Progressive Party (DPP) Legislator Lee Kun-cheng (李坤城), was released on bail of NT$80,000 today amid outcry over his decision to wear a Nazi armband to questioning the night before. Sung arrived at the New Taipei District Prosecutors’ Office for questioning in a recall petition forgery case last night wearing a red armband bearing a swastika, carrying a copy of Adolf Hitler’s Mein Kampf and giving a Nazi salute. Sung left the building at 1:15am without the armband and covering the book with his coat. Lee said today that this is a serious
A mountain blaze that broke out yesterday morning in Yangmingshan National Park was put out after five hours, following multi agency efforts involving dozens of fire trucks and helicopter water drops. The fire might have been sparked by an air quality sensor operated by the National Center for High-Performance Computing, one of the national-level laboratories under the National Applied Research Laboratories, Yangmingshan National Park Headquarters said. The Taipei City Fire Department said the fire, which broke out at about 11am yesterday near the mountainous Xiaoyoukeng (小油坑) Recreation Area was extinguished at 4:32pm. It had initially dispatched 72 personnel in four command vehicles, 16
