Tamil Nadu has crossed a critical public health threshold, registering more than one lakh new cancer cases in a single year for the first time. The latest figures for 2025, according to data submitted in Parliament by the Union Ministry of Health and Family Welfare, show 1,00,097 fresh cases in the state, underscoring a sharp and sustained rise in incidence and raising concerns among health authorities about prevention, early detection, and treatment capacity.   Experts caution that without stronger screening programmes and lifestyle interventions, the numbers could continue to climb in the coming years. The upward trend has been consistent over the past five years. Annual registrations rose from 68,750 cases in 2020 to 76,968 in 2021; 89,265 in 2022; 92,816 in 2023, and 96,486 in 2024, ...

Highlighting the growing financial strain in cancer care across India, a new analysis claims data reveal that cancer treatment is prolonged and costs a significant amount that can push patients and families. Every year, World Cancer Day 2026 is observed on February 4 to raise awareness about the disease that has adverse effects on human life, encouraging not only its prevention but also its detection and treatment. The claims analysis by Care Health Insurance shows that cancer treatment costs are rising sharply, with early-stage treatment typically costing Rs 5–7 lakh per case, while high-complexity and advanced cancers can push expenses to ₹20–30 lakh per treatment, depending on disease progression, care intensity, treatment protocol and period of treatment. This is particularly relevan...

Doctors at AII India Institute of Medical Sciences successfully performed a complex medical procedure to save the life of a 14-month-old girl who had swallowed a two-inch-long metal spring, it said on Thursday, February 5.  The metal spring stuck in the oesophagus, also known as the food pipe, was successfully removed after an endoscopic surgery, AIIMS said in an official statement.  The child, a resident of Yamunanagar, was brought to the hospital after suffering from continuous vomiting for about a week and not eating for two days.   “During the examination, an X-ray revealed a large metal spring lodged in the upper part of the child`s oesophagus,” AIIMS said, "with ulcerations extending along the mucosa". “The spring was stuck on the upper part of the food pipe. And the thickness of...

On the occasion of World Cancer Day observed on February 4 earlier this week, health experts have raised concerns over the rising number of gallbladder cancer cases in Delhi, particularly among women.  Often mistaken for common digestive issues, early symptoms such as acidity, bloating, nausea, or gastric pain are frequently ignored or treated with over-the-counter antacids. This delay in medical consultation leads to late-stage diagnosis, when treatment options become limited. Timely screening and diagnostic testing can play a critical role in improving outcomes and survival. Gallbladder cancer is a relatively rare but aggressive cancer that develops in the gallbladder, a small organ located beneath the liver.  Dr Kavita Jain, senior consultant in oncology pathology, Apollo Diagnostic...

Researchers at the Indian Institute of Technology (IIT) Bombay have developed a simpler and more efficient method to recover immune cells grown in the lab for T-cell–based cancer therapies.  In immunotherapies such as CAR T-cell, T-cells (a type of immune cell) are taken from a patient’s blood and modified in large numbers in the laboratory and infused back into the patient’s bloodstream to help fight cancer. These cells, grown outside the body, must be collected gently so that they remain alive and functional when returned to the patient. Finding safe and efficient ways to grow T-cells and retrieve them is therefore an important part of making these therapies work. “Cell recovery sounds simple on paper, but in practice it turns out to be one of the biggest challenges,” said Prof. Prakr...

As tuberculosis (TB) continues as the deadliest infectious cause of deaths globally, a new study has shown that artificial intelligence (AI)-enabled digital stethoscopes can help fill critical screening gaps, especially in hard-to-reach areas.  In a commentary published in the journal Med (Cell Press), global experts contended that stethoscopes combined with digital technology and AI can be a better option against the challenges faced in screening programmes, such as under-detection, high cost, and inequitable access. “AI-enabled digital stethoscopes have demonstrated promising accuracy and feasibility for detecting lung and cardiovascular abnormalities, with promising results in early TB studies. Training and validation in diverse, high-burden settings are essential to explore the poten...

Amid several claims of vaccination and reduced fertility, a study of nearly 60,000 women showed that the Covid vaccine played no role in a decrease in childbirth.  Since the beginning of the Covid-19 pandemic, unfounded rumours have circulated, especially on social media, alleging that vaccination impairs chances of becoming pregnant.   In the later stages of the pandemic, there was a decrease in the number of children born in some countries, including Sweden. This raised the question of whether this could be due to the new vaccines.  "Our conclusion is that it`s highly unlikely that the mRNA vaccine against Covid-19 was behind the decrease in childbirth during the pandemic," said Toomas Timpka, professor of social medicine at Linkoping University, Sweden.  The study, published in the ...

A world-first Australian trial has found that a simple fingerstick test for hepatitis B DNA is as accurate as standard lab testing, paving the way for wider access in remote and resource-limited settings.  Published in the Journal of Clinical Microbiology, the study showed that the point-of-care test can deliver results within an hour and be performed in decentralised clinics, Xinhua news agency reported.  The fingerstick test can help overcome delays caused by laboratory-based testing, according to a statement from the Kirby Institute at the University of New South Wales in Australia.  "The results of our trial found that the fingerstick point-of-care test is highly accurate, closely matching the accuracy of traditional tests," said Professor Gail Matthews, who led the research at the ...

A team of researchers in Japan has announced a clinical trial to confirm a vaccine`s efficacy against the deadly Nipah virus in humans.  The vaccine candidate developed at the University of Tokyo is set to start clinical trials in Belgium in April, Nikkei Asia, a Japan-based English-language news magazine, reported.  The new vaccine offers a potential breakthrough against a disease whose fatality rate is estimated to be between 40 per cent and 75 per cent.  Currently, there is no licensed vaccine or specific treatment for Nipah virus infection. The latest development comes even as India reported two confirmed cases of Nipah virus from West Bengal in January.   The new vaccine is reportedly being developed by inserting a portion of the Nipah virus`s genetic information into the measles...

Up to four in 10 or 7.1 million cancer cases worldwide could be prevented, according to a new global analysis from the World Health Organization (WHO) and its International Agency for Research on Cancer (IARC) on Wednesday.  The study, released on World Cancer Day on February 4, identified tobacco as the leading preventable cause of cancer globally, responsible for 15 per cent of all new cancer cases. It also found, for the first time, that nine cancer-causing infections are responsible for about 10 per cent of cancer cases. Other reasons include alcohol, high body mass index, physical inactivity, air pollution, and ultraviolet radiation. The analysis, based on data from 185 countries and 36 cancer types, estimated that 37 per cent of all new cancer cases in 2022, around 7.1 million ca...
