A toxic trigger: How plastics may be fuelling cancer
What is BPA and Why Should You Care?
Bisphenol A, commonly known as BPA, is a chemical used in the production of certain types of plastic and resins. It is found in plastic water bottles and food containers, linings of canned foods and beverages, baby feeding bottles, thermal paper receipts, packaging materials, even some medical and dental devices.
Why is BPA a concern? Because it behaves like estrogen — a hormone in our body — and disrupts the normal functioning of our endocrine (hormone) system. For this reason, BPA is called an 'endocrine disruptor'.
How Does BPA Affect Our Health?
Scientific studies have shown that BPA exposure may lead to a variety of health problems, including hormone-related cancers like breast and prostate cancer, infertility in both men and women, early puberty in girls, Polycystic Ovary Syndrome (PCOS), obesity, diabetes, heart diseases, thyroid issues, brain and behaviour problems in children
Even tiny amounts of BPA, when accumulated over time, can pose serious risks to our long-term health, especially for babies, children and pregnant women. Out of all these, the major concern is rising incidence of female breast cancer. As per recent statistics, it tops the chart of all cancers for women in India and in Odisha the threat is nothing less than ominous.
The link between BPA and female breast cancer
Since breast cancer tops the chart among females in India, the causative factors need to be discussed from plastics point of view. Even if there are many factors that are made responsible, no single factor can be pinned as the primary cause rather it is a complex interplay of factors that lead to continuously elevated estrogen level in the blood.
Between 1990 and 2016, the age-standardised incidence rate of breast cancer among Indian women increased by approximately 39.1 per cent. This rise was observed across all States. In Mumbai, data from the Population-Based Cancer Registry indicated a significant increase in breast cancer incidence among older women (aged 50-74 years) from 1976 to 2005, with an estimated annual percentage change (EAPC) of 1.6 per cent. Younger women (aged 25-49 years) also saw a notable rise, with an EAPC of 1.0 per cent.
If we go by observation of plastic use and rise in female breast cancer incidence, roughly the timeline coincides too. Per capita plastic consumption rose from around 1 kg in the 1970s to approximately 13.6 kg by 2018, and further to about 15 kg by 2023. Plastic use has increased to almost 20 to 30-fold since 1970s due to urbanisation, industrialisation and industrial growth.
How You Can Protect Yourself and Your Family:
• Stop reusing plastic water bottles, especially if they are scratched or old.
• Never pour hot liquids into polythene bags. Use stainless steel or glass instead.
• Don't microwave food in regular plastic containers. Use BPA-free labelled containers only.
• Check labels on baby bottles and switch to BPA-free alternatives, preferably steel or glass ones.
• Avoid bottled water stored in sunlight, like those left in vehicles.
• Prefer fresh food over canned food to reduce BPA exposure.

Bariatric Surgery and Its Long-term Benefits: A Conversation with Dr. Manish Khaitan on Diabetes Remission and Beyond
As India confronts the rising tide of obesity-related health issues, bariatric surgery is emerging as an essential solution for patients struggling with weight and related health issues. Dr. Manish Khaitan, Chief Bariatric & Metabolic Surgeon at NObesity Bariatric Surgery Centre in Ahmedabad, has performed over 8,000 surgeries and is a leading advocate for the long-term benefits of bariatric surgery, particularly in diabetes remission and improving overall metabolic health. In a recent conversation, Dr. Khaitan shared his insights into how bariatric surgery offers much more than just weight loss. His extensive work in bariatric care is transforming lives, not only through weight loss but also by offering a solution to many other metabolic health challenges. Dr. Khaitan has demonstrated through research and practice how bariatric surgery has the potential to significantly improve insulin sensitivity and, in many cases, reverse type 2 diabetes. Dr. Khaitan's research has been a key contribution to understanding the broader health benefits of bariatric surgery, especially in the context of India. His study, 'Evaluation of the Effects of Bariatric Surgery in Terms of Weight Loss and Diabetes Remission in the Indian Population' (2021), demonstrated that bariatric surgery could lead to significant improvements in blood glucose levels and the reduction or complete cessation of diabetes medication for many patients. This publication has played a significant role in reshaping medical views about bariatric surgery as a metabolic intervention, not just a weight-loss tool. The link between obesity and diabetes is well-established, and with India now home to one of the highest populations of people affected by type 2 diabetes, the importance of bariatric surgery cannot be overstated. Dr. Khaitan explains, 'Obesity is a chronic disease, and bariatric surgery can be a life-saving intervention that helps patients manage comorbidities like diabetes, hypertension, and heart disease.' His work in this area emphasizes the long-term health improvements that surgery offers, particularly in reducing the risk of chronic diseases. For many patients, bariatric surgery doesn't just improve weight—it also transforms metabolic health. A recent patient, for example, had struggled with obesity and type 2 diabetes for years. After undergoing bariatric surgery, the patient was able to reduce their insulin dependency significantly, and within months, was able to completely discontinue diabetes medication. Dr. Khaitan has seen this result in many patients, illustrating how bariatric surgery leads to more than just weight loss—it helps restore the body's ability to process food and manage glucose levels. In addition to his clinical expertise, Dr. Khaitan has made significant contributions to research in the field of bariatric surgery. His published work includes studies on the long-term benefits of bariatric surgery, including 'Effect of COVID-19 Pandemic on Global Bariatric Surgery Practices' (2021), which explored how the pandemic disrupted bariatric surgeries worldwide. This research has highlighted the challenges that patients faced during the lockdowns and the adoption of telemedicine as an alternative for post-surgery follow-up care. Another key study that Dr. Khaitan contributed to, 'Bariatric Surgery in Immunocompromised Patients: Outcomes from One Year Follow-up' (2018), investigated how bariatric surgery can be safely performed in patients with weakened immune systems. The study found that bariatric surgery, when carefully managed, can offer substantial health benefits even for immunocompromised patients. Dr. Khaitan's work is not limited to research; he has been a leading figure in medical education and surgical training. As a key figure in the Obesity Surgery Society of India (OSSI), he has played a pivotal role in educating surgeons on the latest techniques and expanding access to bariatric care across the country. With over 150 surgeons trained under his mentorship, Dr. Khaitan is helping to build a strong community of bariatric surgeons who can address the growing demand for this life-saving surgery. The increasing need for bariatric surgery in India is having a major impact on the country's healthcare infrastructure. As more patients seek treatment for obesity and metabolic diseases, hospitals and clinics are adapting to provide these services. Dr. Khaitan is at the forefront of this change, ensuring that bariatric surgery is integrated into India's broader healthcare framework. His work has helped reduce the burden of chronic diseases by providing patients with effective long-term solutions, ultimately alleviating pressure on the healthcare system. Looking forward, Dr. Khaitan is optimistic about the future of bariatric surgery in India. He points to the increasing role of robotics in the field and personalized treatment plans based on patient profiles. 'The future lies in making bariatric surgery more accessible, affordable, and effective,' he says. 'With technological advancements and better education, we are moving toward a future where bariatric surgery will be a key component in managing obesity and metabolic diseases.' Dr. Khaitan's leadership, both in clinical practice and in the broader medical community, continues to guide the future of bariatric care in India. Through his contributions to research, education, and patient care, he remains dedicated to transforming how obesity and metabolic diseases are treated in the country. As India's healthcare needs evolve, Dr. Khaitan is helping set the standard for bariatric surgery, ensuring that patients can lead healthier lives with the support of innovative and evidence-based treatment.

Breathing Inequality: Air pollution's disproportionate impact on women
Air pollution is an insidious global threat, yet its impact on women's reproductive health in India remains significantly overlooked. Across both urban and rural landscapes, women are continuously exposed to an invisible but relentless threat to their health through the very air they breathe. While much of the conversation around pollution centers on lungs or heart disease, emerging global evidence shows that air pollution is deeply entangled with hormonal imbalances, ovarian dysfunction, miscarriages, and disorders like polycystic ovary syndrome (PCOS). Despite being one of the most adversely affected nations in terms of poor air quality, India largely ignores this link in research, policy, and public awareness. Women in India are particularly vulnerable to this threat, not only due to their physiology but also because of their social roles and working conditions. Those from lower-income households continue to rely on unclean fuels like firewood and dung cakes for cooking, exposing them to high levels of indoor pollutants. Others, including migrant and informal workers, spend long hours outdoors in urban areas where fine particulate matter (PM2.5) concentrations regularly exceed international safety thresholds recommended by the World Health Organization (WHO). by Taboola by Taboola Sponsored Links Sponsored Links Promoted Links Promoted Links You May Like No annual fees for life UnionBank Credit Card Apply Now Undo The transition between indoor and outdoor environments does not offer protection, it only extends the duration and variety of exposures. This double burden places women at an elevated risk of long-term reproductive harm, a reality that is rarely acknowledged in mainstream discourse. Scientific studies from across the world have revealed how pollutants such as PM2.5, black carbon, benzene, and dioxins can interfere with the endocrine system, disrupt estrogen and progesterone levels, and cause oxidative stress and chronic inflammation. These disruptions contribute to hormonal disorders and reduce ovarian reserve, making conception difficult and increasing the risk of pregnancy complications. Among these, PCOS, a condition marked by irregular menstrual cycles, hormonal imbalance, and cysts in the ovaries, is now being increasingly studied for its link to air quality. Pollutants can trigger mechanisms that exacerbate or even initiate this disorder, yet India still lacks original epidemiological studies exploring this association within our own populations. While global estimates suggest that PCOS affects anywhere between 4% and 21% of women, Indian studies indicate an even wider range, from 2% to as high as 35%, depending on region and diagnostic approach. A recent survey among college-going women in Delhi NCR found a prevalence of 17.4% in the 18–25 age group, double the pooled national average for that demographic. Despite Delhi's notorious air quality and chronic exposure to PM2.5 levels often five to ten times above the WHO recommended limits, there is still no published research examining the direct link between this exposure and PCOS or other reproductive disorders. Most studies from India continue to focus on prevalence and sociocultural risk factors, while neglecting pollution as a possible driver for PCOS. This silence can be costly. The WHO recommends that annual average PM2.5 exposure should not exceed 5 μg/m3, and daily levels should stay under 15 μg/m3. While according to recent Lancet Planetary Health study the entire population of India lived in areas where annual PM2.5 consistently exceeded the WHO guideline, and over 80% lived in areas above national guideline. Much of this pollution comes from incomplete combustion processes, industrial activities, outdated vehicles, biomass use, and open waste burning. For most of the year, residents breathe air that would be deemed hazardous in almost any other country. For women, this chronic exposure may be just as dangerous as cigarette smoking, which is already linked to infertility, miscarriage, and reproductive organ damage. A study published in The Lancet Planetary Health also showed an association between maternal exposure to ambient particulate matter (PM₂.₅) and pregnancy loss (i.e., stillbirth and miscarriage) in South Asian countries. More alarming is the growing body of international evidence showing black carbon particles lodged in placental tissue. These particles, often bound to co-pollutants such as polycyclic aromatic hydrocarbons (PAHs) and dioxins, can travel from the lungs into the bloodstream and reach the uterus, compromising fetal development. A study published in Nature Communications provided the first direct evidence that black carbon particles from air pollution can be detected on the fetal side of the human placenta, highlighting the impact of air pollutants on women and childbirth. Pollutants from vehicular emissions, waste burning, and industrial activity are also known to mimic estrogen, hijacking hormonal signaling and triggering a host of reproductive and developmental problems. The main challenge, however, is that although a few health datasets are available, there is still a lack of well-established, consistently maintained, and nationally accessible electronic health records (EHRs) that researchers can utilize, particularly for studying pregnant women's health in India . In contrast, India lacks a robust, integrated health data management system, underscoring the need for stronger government intervention. Improved health data infrastructure is essential to support research on air pollution exposure and its health impacts, particularly to protect vulnerable populations from disproportionate exposure and associated health risks. This is a critical gap, especially in a country where both air pollution and women's health inequalities are so widespread. Protecting women's reproductive health in India requires urgent attention to the growing evidence linking air pollution to hormonal and reproductive disorders. Policy responses must go beyond urban planning and vehicle emissions to include a gender-sensitive public health strategy. This will improve the diagnosis rate of PCOS and other women's reproductive health issues attributable to air pollution, thereby protecting women, especially during pregnancy. It will also aid informed decision-making to protect vulnerable women and guide actions related to air pollution. Reducing exposure to harmful particles is not only a climate and development imperative but also a national responsibility to safeguard women's well-being and secure the health of future generations. We cannot continue to ignore the silent damage caused by toxic air on women's reproductive health.
