Medical oncologists warn that vaping aerosols containing formaldehyde, acetaldehyde, and heavy metals like nickel and lead may significantly increase future lung cancer risks.
Experts emphasize that the misconception of vaping as 'harmless water vapour' ignores the damage caused by inhaling heated chemical aerosols deep into lung tissue.
Doctors advise immediate medical evaluation for persistent symptoms such as chronic cough, breathlessness, or unexplained weight loss, which are often dismissed by regular vapers.
