Lung cancer risk extends beyond tobacco use, says doctor
Dr Deepak Abrol highlights that environmental pollution and occupational exposures contribute to rising lung cancer cases among non-smokers.
Lung cancer remains a leading cause of cancer-related deaths globally, according to a report by Daily Excelsior. While tobacco consumption is the most established risk factor, Dr Deepak Abrol notes an increasing incidence of the disease among people who have never smoked.
Dr Abrol states that other contributing factors include environmental pollution, lifestyle choices, genetic susceptibility, and occupational exposures. In regions like Jammu, indoor air pollution from biomass fuels used for cooking and heating can expose individuals to harmful particulate matter.
Outdoor pollutants from industrial activities, vehicular emissions, and suspended particulate matter also affect lung health. Furthermore, workers in sectors such as mining, construction, and manufacturing may encounter carcinogens like silica dust, asbestos, and diesel exhaust.
The doctor warned that lung cancer often progresses without noticeable early symptoms. Warning signs include a persistent cough, coughing up blood, chest pain, breathlessness, unexplained weight loss, and recurrent respiratory infections.
Because early symptoms can resemble common respiratory issues, many cases are diagnosed at advanced stages. Dr Abrol suggested that low-dose computed tomography (LDCT) can help detect the disease early in high-risk individuals.
Screening is not a standard procedure for the general public and depends on age and smoking history. Those with concerns regarding family history or pollutant exposure should consult healthcare professionals to assess their individual risks.
