At 9.30pm every night, a poorly-lit, 12-coach train pulls out of Bathinda station in the Indian state of Punjab with passengers of all ages and genders. With their meager belongings and plastic packets containing sheaves of papers and documents, most talk among themselves in hushed tones.
The destination for an average one-third of the 300 passengers of this train is the Acharya Tulsi Regional Cancer Hospital and Research Centre in the Bikaner district of Rajasthan state.
The train covers about 325 km before it reaches Bikaner around 6 a.m. Sometimes the train is delayed by one to two hours. But the passengers do not lose hope.
Over the years, the Bathinda-Bikaner train has earned itself a grim tag as “Punjab’s cancer train” as it ferries hundreds of thousands of cancer patients from this northern Indian state for treatment for this dreaded affliction. The cost of a train ticket is free for any cancer patient while for attendants there is a 75 percent discount on the fare.
The reason for this interstate migration is the cost of cancer treatment. Most of the hospitals in the city of Bikaner are covered under Mukh Mantri Punjab Cancer Raahat Kosh Scheme through which patients can get financial assistance up to 1,500,000 Indian rupees ($1,787). Whereas the scheme is much harder for patients to access in Punjab.
The widespread prevalence of cancer in Punjab – and more recently the adjoining state of Haryana – has helped earn India the unenviable title of the world’s cancer capital. There are many reasons for poor health among Punjab’s population but environmental degradation and water, soil, and air pollution are known to be the most common causes of cancer in India.
Cancer cases in the country are at an all-time high, after public officials shared in Parliament earlier this year that there were 1,496,972 cases in 2023, up from 1,461,427 in 2022. There was a record 300 percent rise in cases between 2017 and 2018. Studies indicated that 1.4 million people had cancer in India in 2020 and the case numbers may rise to 1.57 million by 2025. The reason for this spike may be due to changes in food consumption patterns, increased genetic predisposition to the disease, as well as negligence in seeking medical attention at the onset of cancer.
Another report indicated that Punjab saw a four-time rise in cervical, oral, and breast cancer cases among people over 30 in 2022.
A Forbes India report indicates that Haryana and Punjab have shown moderate economic growth, notching up per capita net state domestic products of 325,000 rupees ($3,879 ) and 195,000 rupees ($2,327) respectively in the financial year 2022-2023. So rising cancer cases may not be directly linked with economic hardship.
Beginning in the 1960s, Haryana and Punjab were two of the prime beneficiaries of the “Green Revolution“ that solved India’s food security problem. The primary outcome of this scientific and agricultural reform was improvement in crop yields. But this transformation relied extensively on increased use of fertilizers and pesticides.
This excess use of pesticides is known to be the major cause of cancer cases in Haryana and Punjab.
Cancer occurs when a cell keeps on growing and dividing uncontrollably, unlike normal cells, which ultimately die. Biochemically, humans have natural protection against cancer through tumor-suppressor genes. Exposure to certain chemicals can mutate tumor-suppressor genes, switching them off. Chronic exposure to pesticides can thereby increase people’s risk of developing cancer.
Consuming a staggering 5,270 metric tonnes of pesticides annually, Punjab is the third largest user and has the highest per capita consumption of such chemicals in India. This high usage results in the accumulation of pesticides in groundwater, drinking water and food. Such contaminants then end up in the human body.
Recent research found pesticide traces in the breastmilk of lactating mothers in Haryana.
Another study showed that in 6.9 percent of cow’s milk samples from Ludhiana in Punjab, the concentration of harmful pesticides such as hexachlorocyclohexane, dichloro-diphenyl trichloroethane or DDT, endosulfan, cypermethrin, cyhalothrin, permethrin, chlorpyrifos, ethion and profenophos were higher than acceptable limits.
Other research indicates the presence of metal pollutants such as arsenic, lead and uranium in the groundwater of Punjab’s Malwa, may also have played a role in the high incidence of cases in the region.
This raises a dilemma: whether the use of such chemicals for improving agricultural production should be prioritized given their impact on people’s health and quality of life.
This cancer disease burden also comes with an economic cost. The cost of surgeries related to cancer ranges between 100,000 rupees ($1,193) to 600,000 rupees ($7,160) depending on the affected organ.
In 2017-2018, Punjab’s per capita health expenditure was around 1,086 rupees ($13), lower than the national average at that time. On average, people covered around 69.4 percent of their out-of-pocket health costs, which was higher than the national average of 48.8 percent.
One way of addressing this serious issue is through a One Health approach. This concept focuses on looking at human health not separately but as part of an integrated and unified whole alongside the health of animals and ecosystems.
An integrated pest management program complies with this concept and can help address the issue of pesticide overuse by using ecologically sustainable methods to control pests. Agricultural land can be made ecologically inhospitable for pests, requiring minimal pesticide use. This will reduce the chemical footprint of agriculture and won’t pollute air, water or soil with pesticides.
Such interventions could encounter major challenges from farmers who are used to chemically-intensive agricultural methods and practices, which is why it’s important to understand the ecological conservation behavior of farmers before implementing such solutions. But they could be the first step toward a lasting solution to the problem of cancer caused by excessive pesticide use.
