Mr. Hoang, 62, a smoker for 40 years, was diagnosed with a lung nodule by doctors, with post-surgical pathology confirming cancer.

Nguyen Van Tuan, 54, from Tay Ninh, asks: "I quit smoking a few months ago, but I still have a persistent cough and mild chest tightness, even though I'm not sick. Has my lung function not recovered yet?"

The Ministry of Health has proposed banning all forms of tobacco product display at retail establishments to eliminate disguised advertising, prevent youth access, and support cessation efforts.
