Tamil Nadu Records Over 1 Lakh Cancer Cases In 2025; Chennai, Kancheepuram Top The List

Tamil Nadu has recorded more than one lakh new cancer cases in 2025, the first time the state has crossed this threshold. Data submitted to Parliament by the Union Health Ministry show 1,00,097 fresh diagnoses, marking a sharp and sustained rise that public health officials say demands urgent action on prevention, screening and treatment capacity, the IANS reported.

The state's cancer registrations have climbed steadily over five years, from 68,750 in 2020 to 76,968 in 2021, 89,265 in 2022, 92,816 in 2023 and 96,486 in 2024. Health authorities warn that without stronger screening programmes and lifestyle interventions the upward trajectory could continue, increasing pressure on hospitals and oncology services.

Women accounted for a slight majority of new cases in 2025, with 53,542 patients, while men numbered 46,555. The total number of people living with cancer in Tamil Nadu now stands at 1,09,097, a figure that reflects both rising incidence and improved survival rates that require ongoing medical and social support.

Urban districts continue to report the highest caseloads. Chennai led the state with 8,505 new cases, followed by Kancheepuram with 7,295 and Vellore with 6,525. Clinicians link higher urban incidence to lifestyle-related risk factors, greater pollution exposure, stress and delays in diagnosis, though rural areas are not immune to the growing burden.

Cancer types differ by gender. Among men, mouth cancer remains the most common, largely attributed to tobacco use, followed by colorectal and stomach cancers. Among women, breast cancer is the leading diagnosis, with cervical and ovarian cancers also contributing substantially. Experts say these patterns underline the need for targeted awareness campaigns and routine community screening, particularly for breast and cervical cancers.

A worrying feature of the state's cancer profile is late-stage detection. Medical professionals estimate that nearly half of cases are identified at advanced stages, which reduces survival prospects and raises treatment costs. Preventive measures emphasised by specialists include regular physical activity, maintaining healthy weight, avoiding tobacco and alcohol, and participating in periodic screening programmes.

Symptoms such as persistent lumps, unexplained weight loss, prolonged pain or other unusual signs should prompt immediate medical evaluation, clinicians advise. Parliamentary data also show that ovarian, breast and cervical cancers together accounted for 10,821 deaths in 2025, a statistic public health specialists describe as a wake-up call for policymakers and communities to prioritise early diagnosis and prevention to curb Tamil Nadu's rising cancer burden.

Health officials say expanding affordable screening, strengthening primary care, training more oncologists and investing in diagnostic infrastructure will be essential. Community outreach, school-based education and workplace wellness programmes can reduce risk factors over time.

Experts urge state and central governments to allocate resources now to expand screening coverage, subsidise treatment for low-income patients and build capacity to manage the growing caseload.
