KOLKATA: Pollution could be responsible for more than half of Kolkata’s lung cancer cases, warned experts at a symposium on the occasion of World Cancer Day on Friday. While cancer patients with squamous cell carcinoma — which is usually linked with smoking — were more common till recently.
Experts said they are now coming across more and more patients with adenocarcinoma, which is evidently linked with declining air quality. “We are seeing an alarming rise in lung cancer patients, and majority of them do not have any history of smoking,” said Woodlands Hospital pulmonologist Arup Halder.
