What you don't feel can still harm you: Malaysia's silent liver cancer crisis
According to Sunway Medical Centre Velocity hepatobiliary pancreatic and liver surgeon Dr Johann Faizal Khan, one of the biggest barriers to improving liver cancer outcomes lies in the absence of effective public screening programmes.
'While high-risk individuals such as those with liver cirrhosis (long-term liver damage that causes scarring and poor liver function) and chronic viral hepatitis are screened, patients who appear relatively healthy may even realise they have either of these diseases,' he remarked.
Dr Johann noted that this issue is not unique to Malaysia but reflects a global trend, with healthcare institutions now dealing with the long-term effects of undiagnosed or untreated chronic liver conditions.
Understanding liver cancer
Liver cancer, particularly hepatocellular carcinoma (HCC), remains one of the leading causes of premature death in Malaysia.
It is the eighth most common cancer in the country, yet it has the second-lowest five-year survival rate among major cancers at just 12.8% according to Malaysia's Health Ministry.
Alarmingly, 74% of liver cancer cases in Malaysia are classified as Stage IV, where treatment options are limited and outcomes are significantly poorer.
However, the absence of early symptoms should not be mistaken as an assurance of good health. Many individuals who do not drink alcohol or engage with what are typically considered as 'high-risk' behaviours assume that they are not at risk.
In reality, liver cancer can develop silently, without any warning signs. As such, Dr Johann stressed the importance of regular health screenings, regardless of one's perceived health status, as early detection remains the most effective way to improve outcomes.
Treatment options to address liver cancer
While the outlook may seem daunting, there are a range of effective treatment options available even for patients with more advanced cases.
Minimally invasive procedures, such as ablation therapies offer a viable alternative to open surgery by reducing surgical trauma, blood loss, and recovery time.
Among these is the NanoKnife surgery, which uses electrical pulses to target and break down cancer cells without damaging the surrounding healthy tissue.
This technique is particularly beneficial for patients with compromised liver function or tumours near vital structures.
This treatment method may also serve as a bridging treatment for patients awaiting liver transplantation or as an option in cases of recurrence, where repeated surgery may risk damaging healthy liver tissue. However, not all tumours are suitable for minimally invasive approaches.
'Larger tumours or those requiring complex reconstructions may still necessitate traditional open surgery, especially when complete resection is the goal,' noted Dr Johann.
In such cases, a partial hepatectomy may be performed to surgically remove the cancerous portion of the liver, allowing the liver to regenerate post-surgery.
For patients with more extensive liver damage, a liver transplant may be required, involving the replacement of the entire diseased liver with a healthy donor organ.
While each approach carries its own set of risks, Dr Johann emphasises that they are not competing methods.
'Neither is considered better than the other. They each play a role and work together to achieve the best outcome for patients,' he pointed out, adding that treatments are guided by a personalised approach, with an emphasis on tailoring care to each patient and adopting precision medicine whenever possible.
Follow-up care after surgery
Even after successful treatment, patients with underlying conditions such as chronic viral hepatitis, liver fibrosis or cirrhosis, remain at lifelong risk. While treatment can halt progression, continued surveillance is critical to detect recurrence early.
Equally important is the patient's role in maintaining liver health. Follow-up care goes beyond medical appointments, with patients strongly advised to adopt healthier lifestyle habits including consuming a balanced diet, avoiding alcohol and smoking, and unregulated traditional medicine, all of which play a critical role in supporting long-term liver health and recovery.
Empowering patients with the knowledge and tools to take charge of their liver health will be just as critical as medical treatment in shaping long-term outcomes.
The evolution of liver cancer treatment, from open surgery to minimally invasive techniques and targeted ablation therapies, marks a significant step forward in patient care.
These advancements not only expand curative options for previously inoperable cases but also prioritise safety, recovery, and quality of life. ‒ July 24, 2025

Getting 'creative' to reform nation's healthcare: Dr Dzul defends Rakan KKM initiative
PETALING JAYA: The controversial Rakan KKM initiative is an attempt to creatively reform the nation's healthcare system, says Datuk Seri Dr Dzulkefly Ahmad. The Health Minister said that due to government's budgetary constraints, he had no choice but to get "creative". 'If you can't give me the resource, allow me to be resourceful. 'We want to retain our specialists, reduce the bleeding, and invest back into public facilities. 'I can't keep asking for more budget - so I'm unlocking value through reforms,' said Dzulkefly. Rakan KKM is a new initiative by the Health Ministry to introduce a "premium economy" or paid service within public hospitals and clinics. Various quarters have voiced fears that the incorporation of Rakan KKM Sdn Bhd signalled a move towards the privatisation of public health services. Dzulkefly was speaking at a launch of the book titled 'Crisis and Community: Covid-19 in Malaysia' at Gerakbudaya here on Sunday (July 27). The book is a compilation of essays on the Covid-19 crisis by all levels of society, edited by Bridget Welsh. At the forum, Dzulkefly insisted that health security must be dealt with 'the same urgency as we defend our borders". 'That means sustained investment in our healthcare workforce. 'I am introducing a "game-changing" initiative where public facilities collaborate with private sector specialists, likely under a GLIC (government-linked investment company) model. 'The idea is to generate revenue through elective services (non-emergency), possibly in specialised private wings within public hospitals. 'Funds generated would cross-subsidise public health services and infrastructure,' said Dzulkefly. He also stated that Covid-19 had shown that the healthcare system has inadequate social safety nets for vulnerable groups such as the elderly and the mentally ill. 'We must never again frame public health and economic survival as rigidly opposed choices. 'Future crisis governance must be targeted, empathetic, data-informed, and inclusive. 'We must design interventions that are community-driven and flexible - not one-size-fits-all,' said Dzulkefly, revealing that Malaysia's struggle to get vaccines earlier in the pandemic exposed a global system skewed in favour of the rich.

Covid-19 exposed our healthcare system's weakness, say doctors
PETALING JAYA: The Covid-19 pandemic has revealed the fragility of the country's healthcare services, says consultant paediatrician and child disability activist Datuk Dr Amar-Singh HSS. 'It is not that we did not know that our health services had been slowly decaying for decades, but we were not allowed to speak publicly about it and always 'today, you will have to manage with what you have'. 'During the height of the pandemic, we experienced desperate cries for help to find an ICU bed for their family members. The support for carers was weak, equipment and resources were limited even in non-pandemic times, stretched thin. 'Some doctors placed their children with grandparents and did not see them for months,' said Dr Amar at a launch of the book titled 'Crisis and Community: Covid-19 in Malaysia' at Gerakbudaya here Sunday (July 27). The book is a compilation of essays on the Covid-19 crisis by all levels of society, edited by Bridget Welsh. Speaking further at the event, which was attended by Health Minister Datuk Seri Dr Dzulkefly Ahmad, Dr Amar said that there must be better preparation for the next pandemic by placing greater emphasis on building our institutional services, especially health, education and social services. Fellow panellist Ampang Hospital paediatrician Dr Tan Hui Siu narrated how the medical officers and healthcare workers trudged through the pandemic and had to make do with what they had as frontliners. 'We were giving our best in caring, but also to provide compassionate care and treatment that soothes and comforts everyone. 'So there was a gap where we were actually preparing those guidelines and with some of the clinicians, but by the time they were implemented, it was inadequate,' said Dr Tan. She talked of how she struggled to cope with the deaths of patients younger than her and how her teams had to care for patients on their deathbeds alone due to the lockdown. Meanwhile, virologist and policy analyst Dr Lyana Khairuddin called for better education on the vaccine naysayers as well as more investments to be made into vaccine research and development. She labelled the frantic search for vaccines during the pandemic as the 'Vaccine Hunger Games'. 'The Hunger Games aside, there was also the fight to actually get a slot to be jabbed,' said Dr Lyana. She said that the pandemic revealed the need for more science education among Malaysians. 'There are still people saying 'I have survived the pandemic and I am not vaccinated and I am okay and healthy'. Then, there are those who say that 'my mother died because she got the vaccine',' said Lyana. She stressed that there must be more conversations on why vaccines were given during the pandemic and more critical thinking so that people do not fall easily for 'popular traditional cures' during the next pandemic.

Rakan KKM part of push to fix public healthcare, says minister
PETALING JAYA: Health Minister Datuk Seri Dr Dzulkefly Ahmad has reaffirmed his determination to reform health financing, calling it a critical mission in his second term as the nation faces rising pressure on its public healthcare system. "This is my second bite of the cherry. I came back with a vengeance to get reform done — especially health financing. "We have studied the issues, we have run the numbers, and now, we must act," he said in his speech at the launch of the book "Crisis and Community: Covid 19 in Malaysia" here today. Dzulkefly said the country can no longer rely solely on annual budget increases, citing limited fiscal space and growing demands on public healthcare. He said there is a need for structural solutions that improve sustainability without compromising access or quality. Part of that broader reform agenda includes Rakan KKM, which he described as a "game-changer" to address talent attrition and generate revenue within the public system. The model allows specialists to offer paid elective services at selected public hospitals, with proceeds reinvested to upgrade facilities and expand capacity. "This isn't about jumping queues for emergency cases. It's about giving people an option for elective procedures while retaining top talent in the public sector." He also addressed concerns about fairness, emphasising that emergency and critical care services will remain fully subsidised and prioritised for all Malaysians. The programme, which provides "premium economy" services, will operate under the ownership of the Minister of Finance Incorporated (MOF Inc), ensuring transparency and public accountability. He said a full media briefing on Rakan KKM is expected soon, where further details on implementation, pricing, and safeguards will be announced. Dzulkefly also urged all stakeholders to support meaningful reform and judge the initiative by its long-term impact on the nation's healthcare system.
