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.
