What every Malaysian needs to know about cancer today

CANCER is no longer the grim death sentence it once was thanks to early detection, personalised treatments, and better awareness, But in Malaysia, fear and misinformation continue to delay diagnosis and cost lives.
OncoCare Cancer Centre Malaysia chief executive officer and senior consultant clinical oncologist Dr John Low, believes that education is the most powerful weapon in the fight against cancer — and he's calling on Malaysians to act early, not after it's too late.
Cancer cases in Malaysia are rising, but so are survival rates, which marks a glimmer of hope amidst growing concern.
'Cancer today is not what it was 20 or even 10 years ago.
'Yes, the incidence of cancer is on the rise, and it is not just among the elderly.
'The good news is that survival rates have improved tremendously and this is the positive shift we are seeing,' Dr Low said.
The Malaysia National Cancer Registry Report 2017–2021 shows that breast cancer continues to top the list, followed by colorectal, lung, lymphoma, and liver cancers.
Dr Low also noted a rise in prostate cancer, likely due to better awareness and screening. Meanwhile, cervical cancer rates are declining thanks to the national HPV vaccination programme.
Although one in eight Malaysians is at risk, early detection and intervention are turning the tide.
Not just for the elderly
The belief that cancer affects only older individuals is increasingly outdated.
According to Dr Low, breast and colon cancer cases in Malaysians under 50 are especially prevalent in today's age, attributing the shift to modern diets high in processed foods, sedentary lifestyles, and rising obesity rates.
'Being young doesn't mean you are immune. Your lifestyle today shapes your health tomorrow,' he said.
Debunking dangerous myths
Misinformation continues to stand in the way of treatment and survival. Dr Low points to three common myths.
The first myth is the ominous 'Cancer is a death sentence.'
'Not true, many cancers are treatable, even curable, especially when detected early.
'With more effective treatments available, survival rates have improved significantly,' Dr Low clarified.
Another myth comes from the often-parroted 'Sugar feeds cancer.'
'Cancer cells use glucose, but so do all your healthy cells. Cutting sugar alone won't cure cancer.
'What matters more is maintaining a balanced and nutritious diet to support your overall health when undergoing treatment,' he elaborated.
Finally, a dangerous myth that is rooted in legacy is that traditional medicine alone can cure cancer.
'Some traditional remedies may support wellbeing or alleviate side effects, but they should never replace evidence-based cancer therapies like surgery, chemotherapy or radiation,' Dr Low stated, clearing misconceptions.
Living with cancer
The fatalistic view of cancer is still widespread, but it's slowly changing.
According to Dr Low, cancer today can often be treated like any other chronic condition in the sense that many people continue to work, travel, and enjoy life during and after treatment.
'With advances like immunotherapy and targeted therapies, some stage 4 cancers can now survive for years,' he added.
He also advocates for a better understanding of palliative care.

Warning signs and lifestyle choices
Many Malaysians ignore early cancer symptoms due to cultural beliefs or fear, Dr Low cautioned.
'Sudden weight loss is often seen as a good thing, but it could be a warning sign of stomach or pancreatic cancer.
Blood in the stool is dismissed as haemorrhoids or spicy food, yet it can indicate colorectal cancer,' he warned
Alternatively, even those who feel healthy should consider regular screenings.
'Cancer does not care how young or healthy you are.
'We are seeing cases like breast, colorectal, and even cervical cancer in people in their 30s,' he said.
Dr Low further affirmed that diet, exercise, and mental well-being significantly affect cancer risk.
According to him, a healthy diet, regular exercise, avoiding tobacco and nicotine from smoking, and managing one's stress all play a key role in reducing cancer risk.
Nevertheless, the most effective protection comes from combining these habits with regular screenings, especially if one's family has a history of cancer that can be linked to be hereditary.

Cutting-edge treatments available in Malaysia
Malaysia now has access to world-class cancer treatments. As mentioned by Dr Low, procedures such as robot-assisted surgeries can effectively remove cancer tumours from previously unreachable areas.
Additionally, modern radiotherapy with the use of artificial intelligence (AI) is similarly effective in delivering precision doses, sparing healthy tissues in the process.
He also added that breakthroughs in immunotherapy and targeted therapy are game-changers.
'We can now switch off cancer-driving mutations directly. Immunotherapy drugs use monoclonal antibodies that home in on cancer cells.
These treatments are more effective and less harmful, increasing the chance of cure,' he said.
On the up-and-up, gone are the days of one-size-fits-all treatment in Malaysian cancer research. Cancer today can often be treated like any other chronic condition in the sense that many people continue to work, travel, and enjoy life during and after treatment. Photo: Canva
'Personalised cancer care targets the specific genetic profile of your cancer.
'This tailored approach not only improves effectiveness but also reduces side effects and enhances quality of life,' Dr Low added.
If there's one thing Dr Low wants Malaysians to remember about cancer, it's this:
'Cancer is not a distant threat; it can affect anyone, regardless of age, gender, or lifestyle. But early detection, regular screenings, and proactive health choices can make all the difference.
'Cancer is not the end – it can be a new beginning. Be aware, stay healthy, and most importantly, don't wait. Your body is always speaking, so make sure you are listening.'

Holistic approach key to appropriate acne care

PETALING JAYA: In conjunction with Acne Awareness Month, a leading dermatologist has urged Malaysians to move beyond creams and antibiotics, and adopt a more holistic approach that considers gut health, diet, mental well-being and the emotional toll of the condition. 'Acne is a multifactorial skin condition that extends far beyond visible lesions. A holistic approach not only improves outcomes but also addresses the emotional burden carried by many patients,' said Consultant Dermatologist Dr Teeba Raja, who also serves as president of the Malaysian Allergic Contact Dermatitis Subcommittee. She explained that emerging research has drawn attention to the gut-skin axis, where imbalances in gut bacteria – known as gut dysbiosis – can drive skin inflammation. 'Increased intestinal permeability, or 'leaky gut', allows endotoxins such as lipopolysaccharides to enter the bloodstream and trigger inflammatory responses in the skin. 'While gut-directed therapies are not yet part of standard acne treatment, patients with both acne and gastrointestinal symptoms may benefit from addressing underlying gut issues,' she said. Teeba also highlighted the role of diet, noting that high-glycaemic foods and dairy have been linked to acne severity. 'Low-glycaemic diets help by lowering insulin and IGF-1 levels – hormones that stimulate oil production and skin cell growth. 'Dairy, especially skim milk and whey protein, can aggravate acne in some individuals due to its hormonal effects.' She added that probiotics, particularly strains such as Lactobacillus and Bifidobacterium, may help reduce skin inflammation, but should be seen as complementary rather than primary treatments. Mental health is another critical yet often overlooked aspect of acne care. 'Many patients experience depression, anxiety and social withdrawal due to acne. Some studies have found it to be more psychologically distressing than chronic conditions like asthma or diabetes. 'In Malaysia, adolescent surveys show acne is a common cause of emotional distress and social stigma.' Teeba called for routine mental health screening during dermatology consultations. 'We should normalise checking in on patients' emotional well-being. Tools such as dermatology-specific quality-of-life questionnaires can help identify those who need psychological support.' She recalled one case involving a 19-year-old male with severe nodulocystic acne. 'After years of failed treatments, he was started on isotretinoin. In six months, not only did his skin improve dramatically, but his self-esteem and overall quality of life returned. It was a reminder that acne care can be life-changing when done right.' Teeba also warned against common self-treatment mistakes, such as over-cleansing, pimple-popping and frequent product switching. 'These habits worsen inflammation, damage the skin barrier and increase the risk of scarring. Patients should be educated to follow a consistent, gentle routine and apply treatments across the entire acne-prone area, not just on visible spots.' She pointed out that social media has become a double-edged sword in acne management. 'Teens are constantly exposed to filtered images and miracle-cure content, which creates unrealistic expectations. Some abandon effective treatments in favour of viral trends. We must teach patients to critically evaluate online content and follow credible sources.' While public awareness of acne in Malaysia is growing, stigma remains a persistent barrier. 'Studies show that over 76% of people view acne negatively in photographs, associating it with poor hygiene or unattractiveness. We need greater public education to dismantle these harmful myths.' Ultimately, she said acne treatment must extend beyond prescriptions.

From cushy life to offering a lifeline

Beacon of light: Florence and her staff in a discussion at the Sneham office in Seri Berapit, Bukit Mertajam. — ZHAFARAN NASIB/The Star Corporate high-flyer finds a greater calling to help those in need BUKIT MERTAJAM: She once sat in posh boardrooms, drawing a high salary, steering corporations and troubleshooting problems across Asia. At the peak of her career, Datuk Dr Florence Sinniah did something few dare to do – she walked away. Not for a higher post or early retirement, but to listen to the cries of people crushed by grief or despair. 'I left when I was doing my best work. My performance was consistently in the top tier. 'But I knew I had another calling,' said Florence, founder and chairman of Sneham Malaysia – a renowned toll-free suicide prevention helpline. From corporate corridors to hospital wards, Florence wore many hats. She has worked as a psychiatric nurse, a midwife and a senior human resources (HR) director in multinational companies. It was during her HR career – navigating the mental breakdowns of top-performing employees – that she discovered her purpose. 'One case that changed me was an engineer who broke down from the pressures of managing a global team. 'I realised then that I had the ability to connect with people deeply, and that the mental health of people cannot be an afterthought,' she said in an interview. That realisation planted the seed that would grow into Sneham, which in Tamil means 'love' or 'friendship'. Florence began volunteering with the Befrienders hotline in 2009, quietly taking the graveyard shift from midnight to 6am every Friday – just to be there for those in crisis. By 2018, she knew she had to go further. She resigned and launched Sneham in October that year. Today, Sneham is powered by 35 dedicated volunteers, supported by 48 members in total. It's more than a hotline – it's a lifeline for those trapped in darkness. 'In a world where emotional pain is often invisible, just having someone to listen without judgment can save a life,' she said. Since 2019, Sneham has answered 9,235 calls, responded to 2,292 WhatsApp messages, provided 128 in-person counselling sessions, and reached 193 schools and communities with outreach programmes. During the pandemic period, calls surged from 375 in 2019 to 1,885 in 2023, showing how isolation and despair gripped a higher number of people. But running a lifeline isn't easy. Florence is candid about the struggles. 'We're constantly working to expand our volunteer pool and secure enough funding to keep going,' she said. In 2020, Sneham was recognised globally with the Stars of Covid Award – one of 100 selected from over 1,600 nominations. Behind the numbers lies the beating heart of a woman who gave up comfort to sit with people in their darkest moments – simply to remind them that they matter. Meanwhile, the Star Golden Hearts Award (SGHA) returns for the 11th edition to honour everyday Malaysians whose compassion and selflessness have made a lasting impact on others. With McDonald's Malaysia as the new strategic partner, SGHA is poised to broaden its reach and deepen its impact nationwide. This year also marks the debut of the McDonald's Caring Hearts Award – a special recognition honouring individuals or grassroots groups whose heartfelt acts of kindness have uplifted lives in profound and lasting ways. Since its inception in 2015, SGHA has honoured more than 100 individuals and organisations whose efforts have inspired action, transformed lives and strengthened communities nationwide.
