Cancer has been seen as a disease of aging, but now it is frightening statistics that reveal the rise of early-onset cancers among millennials. Estimates indicate that about 1.9 million people are newly diagnosed with cancer in the U.S. every year. This number will increase to 2.3 million by 2030. More and more studies are indicating that lifestyle disorders, such as an unhealthy diet, sedentary lifestyle, stress, and disrupted sleep patterns, may be a cause for which younger populations are increasingly becoming vulnerable to malignancies, including rare and aggressive types of cancer.

Has COVID-19 Worsened the Cancer Epidemic?

It has not been new news that viruses can provoke or accelerate cancer development, but research is still ongoing to understand the long-term impact of COVID-19 on cancer risk. What has already been determined, however, is that the pandemic indirectly worsened the outcomes of cancer. Delayed screenings, postponed treatments, and risks of increased mortality have all been noted globally.

The Lancet Public Health published research that underlines these consequences, indicating that the pandemic slowed or even reversed the declining cancer mortality rates observed before SARS-CoV-2 emerged. Delays in surgeries and chemotherapy treatments significantly impacted survival rates. For example, every four-week delay in colon cancer surgery increases the risk of death by 6%, while similar delays in adjuvant chemotherapy for colorectal cancer elevate mortality risk by 13%.

How Lifestyle Choices Are Driving Early-Onset Cancers

Dr. Priya Tiwari, Head of Medical Oncology, says that lifestyle choices play a critical role in the increasing incidence of cancer among young adults.

Poor diet rich in processed foods, high sugar, and red meat. Obesity and metabolic disorders are so closely linked with various cancers says Dr. Tiwari, "A sedentary lifestyle further compounds this risk, creating insulin resistance, vitamin D deficiency, and chronic inflammation, factors that are more strongly associated with colorectal and breast cancers,"

Susceptibility is further aggravated by tobacco usage, excessive alcohol consumption, and exposure to carcinogens. Stress and sleep deprivation also disrupt the balance of hormones and compromise immune function, leading to an environment conducive to tumorigenesis.

The association between stress, inflammation, and cancer.

Millennials face unprecedented levels of stress, driven by work pressures, financial instability, and excessive screen time. Chronic stress triggers the sustained release of cortisol and inflammatory cytokines such as IL-6 and TNF-α, which fuel systemic inflammation.

"Prolonged inflammation weakens immune surveillance, making the body less capable of detecting and eliminating cancerous cells before they grow uncontrollably," explains Dr. Tiwari.

The circadian rhythms have been disrupted due to late-night working hours and increased exposure to blue light. Decreased melatonin production, which is a natural cancer-fighting hormone, is associated with a higher incidence of hormone-related cancers, including breast and prostate cancer.

Are Rare and Aggressive Cancers on the Rise Post-Pandemic?

There is a rise in rare and aggressive cancers, which have been reported by medical experts post-pandemic, and possible reasons for this increase may include delayed screenings and lingering inflammatory effects from COVID-19. Many patients avoided routine health check-ups at the height of the pandemic, and this has led to late-stage diagnoses of malignancies like sarcomas, glioblastomas, and neuroendocrine tumors.

In addition, there is a theory that SARS-CoV-2 might have a part in tumor progression due to cytokine storms induced by interleukin-6 and tumor necrosis factor-alpha. This state of chronic inflammation might accelerate the growth of the tumor in predisposed individuals.

Should Millennials Start Cancer Screening Early?

Earlier, cancer screenings were typically recommended to the older people. However, with the increase of early-onset cancers among the young, screening guidelines have been revised for younger groups of populations. According to Dr. Tiwari, while universal screening is perhaps not required, screening should start earlier in cases of genetic predisposition or family cancer history.

Screening Requisiste includes:

1. Mammograms for women below 40 years of age who have a family history of breast cancers.

2. Colonoscopy for patients with a history of colorectal cancer in their family.

3. Pap smears and HPV tests for cervical cancer starting at age 21.

4. Skin exams for melanoma for those with increased sun exposure or family history.

How To Balance Lifestyle Choices And Reduce The Risk Of Developing Cancer?

Dr Priya emphasises, "A healthy lifestyle that includes nutrition, exercise, and stress management can prevent cancer in young adults. An antioxidant diet rich in fiber and omega-3 fatty acids decreases inflammation and protects against carcinogenesis. Exercise improves the regulation of insulin levels and inflammatory cytokines, thereby lowering risks of obesity-related cancers. Limiting tobacco and alcohol consumption as well as exposure to environmental toxins such as PAHs and endocrine disruptors can also reduce the risk of cancer further. Improved sleep hygiene, mindfulness for stress management, and other circadian rhythm-enhancing behaviors can also decrease the immunosuppressive effects of cortisol and therefore improve overall health."

Cancer prevention in young adults is only possible through preventive lifestyle changes. A healthy diet, regular exercise, stress control, and minimal exposure to known carcinogens will greatly reduce the risk of cancer. Here is a concise list of changes you should make now:

  • Eat a Healthy Diet
  • Increase antioxidant intake through foods such as berries, nuts, and leafy greens.
  • Choose whole grains instead of refined carbohydrates.
  • Use sources such as salmon, flaxseeds, and walnuts to increase intake of omega-3 fatty acids.
  • Stay Physically Active
  • Perform at least 150 minutes of moderate-intensity exercise weekly.
  • Limit sedentary time for extended periods by incorporating moving activities during the day.
  • Manage Stress in a Healthy Way
  • Use mindfulness, which may include meditation and deep breathing, to manage the changes.
  • Work-life boundaries can help alleviate chronic stress and prevent burnout.
  • Improve Sleep Hygiene
  • Reduce exposure to screens before bedtime to preserve melatonin.
  • Develop sleep habits that allow for at least 7 to 9 hours of sleep each night.
  • Limit Exposure to Hazardous Substances
  • Cut back on alcohol consumption and quit smoking.
  • Limit exposure to environmental toxins like PAHs and endocrine disruptors.

Increasing incidence of cancer in the millennial age group demands the need for urgent awareness and lifestyle changes. There is certainly a genetic contribution to cancer; however, lifestyle determinants, including diet, exercise, and management of stress, can all affect the course of cancer.

"Preventive care, including routine screenings and healthier lifestyle choices, holds the key to reducing the risk of cancer for young adults," said Dr. Tiwari. "Making conscious adjustments today will help millennials safeguard their health for tomorrow."

Since cancer trends continue to evolve, embracing proactive health measures, and then keeping prevention at par with treatment, will be imperative in reducing future burden caused by this disease.

Daylights Savings Time May Be Causing You Higher Risk Of Heart Attacks And Obesity, Study Backs Fixed Standard Time

Updated Sep 16, 2025 | 10:00 PM IST

SummaryMany Americans agree with the fact that daylight savings time cause them to face many issues, whether it is lack of sleep or less time to do things etc. However, new research shows that it not only does this disrupt your timetable, but also your health. Here is what you need to know.
Daylights Savings Time May Be Causing You Higher Risk Of Heart Attacks And Obesity, Study Backs Fixed Standard Time

A new study from Stanford University suggests that daylight saving time isn't just an inconvenience; it could actually be bad for our health. The research shows that our twice-a-year routine of changing the clocks disrupts our bodies' natural rhythms, which can lead to serious health issues. This is a big deal because it provides the first real scientific evidence that this time-switching practice has a biological cost.

What is Daylight Saving Time?

According to the Sleep Foundation, daylight saving time (DST) has been an official practice in most of the United States since 1966. Only a few places, like Hawaii and parts of Arizona, don't follow it. The routine is simple: on the second Sunday in March, we set our clocks forward by one hour, losing an hour of sleep. Then, on the first Sunday in November, we set them back, gaining that hour of sleep. This is why many people remember it as "Spring Forward, Fall Back."

How Daylights Saving Time Affects Our Health

According to the study, if the U.S. got rid of daylight saving time and stayed on standard time all year, it could prevent thousands of strokes and significantly reduce obesity. The researchers, using mathematical models and data, estimated that this single change could prevent 300,000 strokes and lead to 2.6 million fewer people with obesity every year. This adds to what we already know about the negative effects of the time change, such as a spike in heart attacks and car crashes in the days after we lose an hour of sleep in the spring.

How Does Daylight Saving Time Affect Sleep?

Our body's internal clock is heavily influenced by light. When the clocks change, the amount of natural light we get in the morning and evening shifts. This can throw off our sleep-wake cycle, making it harder to feel alert in the morning and sleepy at night.

The “spring forward” change is particularly hard on us. One study found that on the Monday after the time change, the average person gets 40 minutes less sleep. This lack of sleep can build up over time, affecting our mood and increasing the risk of accidents.

While the "fall back" change in November can give us an extra hour of sleep, some people still struggle to adjust to the new schedule. For most people, the effects fade after a few days, but some studies suggest that others never fully adjust, leading to ongoing health problems.

Why Time Changes Mess With Our Bodies

The core problem lies in our body's internal clock, or circadian rhythm. Think of it as the conductor of an orchestra, directing all your body's processes. When it's working well, everything is in sync. But when it's thrown off, like by getting light at the wrong time of day, your body's systems can become disorganized.

This can weaken your immune system, mess with your sleep, and increase your risk for diseases like stroke and obesity. The study found that switching between standard and daylight saving time is the worst thing we can do for our body clock, much worse than staying on either time year-round. It's a bit like having the conductor suddenly change the tempo for no reason—the whole orchestra, or in this case, your body, gets thrown off.

India’s top health research body has suggested that new antibiotics launched in the country should only be made available through select hospital pharmacies. The advice comes amid rising fears of misuse, overuse, and growing resistance to even the most critical ‘last-resort’ antibiotics.

In a recent paper published in the Journal of Global Health, ICMR’s antimicrobial resistance (AMR) division, along with other researchers, warned that while new antimicrobials bring hope, past experience shows resistance often develops quickly.

What is antimicrobial resistance?

Antimicrobial resistance, or AMR, happens when bacteria, viruses, fungi, or parasites evolve to survive the medicines meant to kill them. That makes infections harder to treat, weakens the power of drugs, and can turn routine illnesses into life-threatening ones. The World Health Organization has called AMR a global health crisis, driven by the careless use of antibiotics in humans, animals, and agriculture.

ICMR’s surveillance data paints a worrying picture. Klebsiella pneumoniae, a common hospital bug, is now 62.3% resistant to carbapenem (a powerful antibiotic used as a last line of defense). E. coli has also grown tougher, with its resistance to key drugs like imipenem and piperacillin-tazobactam rising sharply in the last six years.

According to the Global Research on Antimicrobial Resistance (GRAM) project, between 3 and 10.4 lakh people in India died in 2019 due to bacterial AMR. Six superbugs which are E. coli, Klebsiella pneumoniae, Staphylococcus aureus, Acinetobacter baumannii, Mycobacterium tuberculosis, and Streptococcus pneumoniae were linked to more than 2.14 lakh deaths that year alone.

Why Misuse Is The Biggest Driver

Easy access to antibiotics without prescriptions, over-the-counter sales, and reckless prescribing habits remain the main culprits behind rising resistance. While India introduced a National Policy for Containment of Antimicrobial Resistance in 2011 and rolled out measures like Schedule H1 to restrict sales, a red line awareness campaign on antibiotic packs, and revisions to the National List of Essential Medicines, the results have been patchy due to poor enforcement.

One area where India has shown stronger regulatory control is tuberculosis treatment, where strict monitoring of drug use has helped maintain effectiveness for longer. Experts say a similar model is needed for all new antibiotics.

Why Stricter Rules Are Urgent

The World Health Organization’s AWaRe framework divides antibiotics into three groups:

  1. Access (narrow-spectrum, safer, and cheaper drugs that should be widely available)
  2. Watch (higher resistance potential, meant for hospital settings)
  3. Reserve (last-resort drugs for severe, multi-drug resistant infections)
But India’s first large-scale government study on antibiotic use, released in 2024, found that 57% of antibiotics prescribed in the country were from the “Watch” or “Reserve” categories, the very ones that need the most caution.

In India, antimicrobials have traditionally been available through retail pharmacies and hospital formularies. While this approach makes drugs easily accessible, it does little to prevent misuse. With treatment options for multidrug-resistant infections running out fast, it has become essential to explore every possible way to curb the improper use of newer antibiotics. In this context, ICMR’s new recommendation to restrict sales could prove to be a useful step.

Rabies Deaths in India: Why People Still Die Despite Effective Vaccines

Health and Me

Updated Sep 16, 2025 | 04:56 PM IST

SummaryRecently, reports have emerged of people dying of rabies despite being vaccinated. Doctors, however, caution that the problem does not lie with medical science but with lack of awareness, and perhaps with a vaccination protocol that needs a change.

A 47-year-old autorickshaw driver from Royapettah, who had received a full course of vaccination after being bitten by a stray dog in July 2025, died of rabies at the Rajiv Gandhi Government General Hospital (RGGGH). He is the 22nd person to succumb to the disease in Tamil Nadu this year.

His death has left experts asking a difficult question, if protocols were followed, why are people still dying? Public health specialists suggest this may not just be a failure of administration, but a sign that India’s long-standing rabies protocol itself needs re-examination.

What Is Rabies?

Rabies is one of the deadliest yet most preventable viral infections known to humanity. The World Health Organization describes it as a vaccine-preventable zoonotic disease that attacks the central nervous system. In nearly 99% of human cases, the virus is transmitted by dogs.

“Rabies infects mammals, including dogs, cats, livestock and wildlife. It spreads to people through saliva, usually by bites, scratches, or direct contact with mucous membranes such as the eyes, mouth, or open wounds. Once symptoms appear, rabies is virtually 100% fatal,” explains Dr. Surrinder Kumar, MBBS, General Physician.

Why Rabies Deaths Still Happen in India?

Despite the availability of effective vaccines, India continues to record thousands of rabies deaths every year. Dr. Surrinder says the problem is not medical science but lack of awareness and timely action. “Rabies remains endemic in India. Vaccines and immunoglobulins work, but the virus attacks the central nervous system and once symptoms begin, it is almost always fatal. The real challenges are late treatment, poor awareness, and preventive gaps.”

For those unversed, Rabies immunoglobulin is a medication made up of antibodies against the rabies virus. It is used to prevent rabies following exposure.

According to Dr Surrinder, the main reasons are:

  1. Delayed or No Medical Attention: Many victims dismiss dog bites as minor and fail to seek immediate treatment.
  2. Lack of Awareness: In rural and semi-urban areas, people often don’t know the importance of post-exposure vaccination.
  3. Reliance on Home Remedies: Turmeric, lime, oils, and other traditional remedies are still used, offering no protection.
  4. Incomplete Vaccination: Even if treatment begins, many patients drop out midway, making it ineffective.
  5. Limited Access to Rabies Immunoglobulin (RIG): For severe bites, RIG is essential along with vaccines, but its high cost and patchy availability block timely use.

The Ground Reality of Rabies Treatment

Dr Shaswath Kumar G. S., a Bengaluru-based veterinarian, explains that anyone bitten by a stray dog without a known vaccination history must undergo the full course of rabies shots, along with immunoglobulin injected directly at the bite site. Before this injection is given, patients are required to undergo an allergy test, which often causes hesitation. He also points out that it may not always be free in government hospitals. The procedure itself is painful since the immunoglobulin is delivered directly into the wound.

Alongside immunoglobulin, at least five separate rabies vaccine doses are necessary. These, Dr. Shaswath says, are not without side effects, as “every time people take the vaccine, they get fever.” While cities are able to conduct mass vaccination campaigns, rural areas face significant challenges in this regard.

He further stresses that rabies is not confined to dog bites alone. The virus can also spread from other animals, and in rare cases even from humans, if infected saliva comes in contact with open wounds or mucous membranes. “A bite isn’t always necessary,” he warns.

Dr. Ranjeet Singh, Professor and Head of General Medicine at NIIMS Medical College and Hospital, echoes the same concerns. He emphasises that rabies deaths in India do not reflect a failure of the vaccine itself. Instead, the main reasons are late treatment, lack of awareness, incomplete vaccination, shortage of immunoglobulin, and limited access in rural areas.

Is India’s Rabies Vaccination System Flawed?

Experts stress that it would be wrong to doubt the vaccine itself. Doing so, they warn, could undermine public trust. “We have a robust programme. The National Action Plan for Rabies Elimination by 2030 (NAPRE) is already in place, and the vaccine’s efficacy is very strong,” doctors underline.

India follows the WHO-approved five-dose rabies vaccine protocol, with immunoglobulin recommended for severe (Category III) bites. But the bigger question, they say, is whether the protocol assumes ideal conditions, which is immediate wound washing, uninterrupted cold chain storage, and trained professionals administering injections at the wound site. In reality, these conditions are not always met.

Common Mistakes After a Dog Bite Which Can Lead To Rabies

Dr. Ranjeet Singh highlights errors that often cost lives:

  1. Not washing the wound immediately: The first step after a bite is washing with soap and running water for at least 15 minutes. Most skip it.
  2. Covering the wound too soon: Tying cloth or applying bandages traps the virus inside.
  3. Applying irritants: Substances like chili, lime, or ash worsen the wound and delay treatment.
  4. Ignoring minor bites or scratches: Even tiny wounds can transmit rabies if saliva enters.
  5. Stopping the vaccine midway: Completing the full course is essential; partial doses give no real protection.

To end rabies deaths in India, awareness must go hand in hand with medical access. Every bite, no matter how small, needs immediate action: wash, vaccinate, and if severe, take immunoglobulin.

“Rabies is 100% preventable but 100% fatal if ignored. No bite should ever be taken lightly. The key is simple, wash, vaccinate, and complete the course,” concludes Dr. Surrinder Kumar.
