The doctor will be arriving ... in a mailbox
You can now do self-administered tests for everything from thyroid function to Human Immunodeficiency Virus (HIV) in the privacy of your own home – and that list continues to grow, as the United States Food and Drug Administration (FDA) recently approved the first at-home cervical cancer test.
While the tests can make it easier for people to access healthcare and can be helpful for those who have extreme anxiety about sensitive or invasive medical exams, experts warn that most of the tests cannot replace an actual in-person visit.
Here's what doctors say you can test for at home, and when you should make the trek to your physician's office.
There are two kinds at 'at-home tests.'
In one type, the patient collects the sample and sends it off to a lab; the new cervical cancer test is like this.
The other gives an instant result – think Covid-19 and pregnancy tests.
HIV home-testing kits can improve rates of diagnosing sexually transmitted infections (STIs) in rural communities and help people who are nervous about going to the doctor to seek a sensitive test, said Dr Joseph Cherabie, an infectious diseases specialist in St. Louis, Missouri.
'You really want to get people to care as quickly as possible, but some people could be very anxious about that results as well,' Dr Cherabie said. 'And they have very negative reactions.'
Labs are required to report a positive HIV test, instead of putting the onus on the patient who took the test, he said, and often, the patient is matched up with HIV support services.
'If you are part of a sexual and gender minority community, going to a doctor's office can be full of a lot of historical trauma, and you may prefer to just do testing at home without anyone judging you or asking you invasive questions about your sex life,' Dr Cherabie said.
The new cervical cancer test – which tests for strains of human papillomavirus, or HPV – involves a testing swab that's like a tampon, said Dr Susan Modesitt, a gynaecologic oncologist at Emory University in Atlanta.
It is not, she said, a replacement for a Pap smear, the exam in which a metal speculum is inserted in the vagina to scrape cervix cells.
A doctor's visit also involves a pelvic exam, a chance to talk about abnormal bleeding – a sign of endometrial cancer – and other symptoms and issues, like menopause or STIs.
'There are so many other reasons to see your doctor and get an exam outside of a cervical cancer screening,' Dr Modesitt said.
The at-home cervical cancer test from Teal Health requires a prescription, and the company said that results are not left for the patient to interpret.
Colon cancer screening
Some at-home tests can replace a trip to the doctor's office.
That's especially true in rural areas, where it can be difficult to get a colonoscopy.
'The colonoscopy requires a pre-op, and you have to drive maybe 70 miles (113km) for it,' said Dr Steven Furr, board chair of the American Academy of Family Physicians who practices in rural Alabama.
'You get anaesthesia. It's actually almost like a surgical procedure in many ways.
'So, for a lot of people, that's pretty arduous. That's where an at-home test can come in handy.'
But, Dr Furr said, if your test reveals issues, you need to go to your doctor.
Plus, patients should always discuss test results with their physician instead of interpreting them on their own, he said.
If you have symptoms of what you're testing for, go to the doctor.
At-home colon cancer tests aren't the right option for people with a history of colon cancer or high-risk conditions, such as inflammatory bowel disease, said Dr Zachariah Foda, a gastroenterologist at Johns Hopkins.
He added that they're also not recommended for people who are having gastrointestinal symptoms.
While there are tests for many things – running anywhere from $15 (RM64) to $400 (RM1,693), depending on what is being evaluated – Dr Furr said it's essential to make sure that your test is FDA-approved so you can better trust the results.
'Anytime we get people involved in their own healthcare and help them understand what's going on, I think that's a good thing and it gives us a chance to talk,' he said.
'Any kind of screening is better than no screening.' – AP

Teens push for digital detox trend
Working on their vision: LifeUp Organisation founders Li Xuan and her brother Yu Wei (right) interviewing a family about their experience with digital detox during one of their programmes this month. Siblings turn their struggle into a movement using interactive games and more JOHOR BARU: Like many teens, Liew Li Xuan developed an unhealthy screen addiction and was glued to her smartphone during the Covid-19 pandemic, which affected her grades and even sparked frequent arguments with her father. Now, the 18-year-old has turned her personal struggle into a movement to help other youths unplug from the digital world. 'Back then, I was addicted to doom-scrolling and spent excessive amounts of time online. I often argued with my father, who intervened by changing our home's Wi-Fi password and confiscating my phone. 'Although I was furious at the time, it was also a turning point. After some reflection, I realised I had to regain control of my life rather than let my unhealthy habits take over,' she said in an interview. Together with her 16-year-old brother Yu Wei, the siblings started LifeUp Organisation two years ago to promote digital detox and healthier online habits among children and teenagers. With the support from their father, the teens began conducting online and in-person activities to encourage digital well-being, tackle cyberbullying and educate youths on online scams. To date, they have attracted participants as young as 10 and older adults, using interactive methods such as mini games and puzzles to convey their message. 'We have seen that even children under 12, who have access to social media, are affected by curated content, which can harm their self-worth and confidence. 'This is why our work is important – to help them take a step back and live more intentionally,' said Li Xuan. She added that one of their most effective initiatives is their regular screen-time reduction challenge. 'We encouraged people to cut their screen time by at least 20%, but some managed to reduce it by up to 95% through conscious effort. That really encouraged us to keep going,' she said. The siblings fund their programmes through self-raised funds and sponsorships from multinational companies. Beyond digital detox workshops, the siblings, along with eight other volunteers, have also organised community service activities at charity homes in Johor Baru. Li Xuan's work also led to her appointment as a speaker under the Malaysian Communications and Multimedia Commission's Safe Internet Campaign, where she gives talks to pupils in Chinese schools in Johor on internet safety and healthy digital habits. 'Our group has recently started a podcast in hopes of reaching out to more people about the importance of taking a digital detox,' she added. Li Xuan, who will be pursuing A-Levels at a private college in Selangor this August, said she has gained valuable leadership and organisational experience through her activities. 'As my peers and I further our studies across the country, we hope to start similar movements in our respective campuses,' she added. Now that she has turned 18, Li Xuan hopes to formally register the group under the Registrar of Societies to expand their programmes and reach more communities. 'I want to continue this journey and inspire more young people to take charge of their digital wellbeing,' she said.

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. 'It is not about giving up, but improving the quality of life. Living with cancer is possible. Early detection, timely care, and emotional support make all the difference.' Procedures such as robot-assisted surgeries can effectively remove cancer tumours from previously unreachable areas. Photo: Canva 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. Cancer is no longer the grim death sentence it once was — thanks to early detection, personalised treatments, and better awareness, yet in Malaysia, fear and misinformation continue to delay diagnosis and cost lives. Photo: Canva 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.'
