Can Daily Pollution Increase Cancer Risk: When we think of cancer, the first thing that comes to mind are big and scary risks. That is, those dangers on which clear warnings are written, but experts say that this is not the complete picture. According to medical oncologist Dr. Rajeev Vijayakumar, the risk of cancer often builds gradually, through small everyday habits and exposures that we hardly pay attention to. A little pollution, not applying sunscreen, lack of sleep, eating too much processed food, all these do not seem serious at that time, so they remain ignored.
Less discussion of micro-exposure
Doctors say that these ‘micro-exposures’ are rarely discussed in general conversations about cancer. These are not visible enough to create fear, but they are present every day and keep accumulating impact over time. For example, air pollution, vehicle smoke, construction dust and fine particles emitted from fuel combustion (PM2.5) can reach deep into the lungs. Long-term exposure to these has been found to be associated with an increased risk of lung cancer, even in non-smokers. The impact of one day may seem minor, but it accumulates over years.
Similarly ultraviolet rays. People become alert when they get sunburned due to strong sunlight on the beach, but daily light exposure like commuting to office, riding a two-wheeler, outdoor exercise is often ignored. Chronic mild UV damage can increase DNA changes in skin cells.
Our lifestyle also has an impact
Experts say that food is also important. Processed meats, excessive alcohol, chronically high sugar levels, and the associated obesity may not appear overnight, but inflammation, insulin resistance, and hormonal changes in the body create an environment in which abnormal cells can proliferate. Deterioration of sleep and circadian rhythm is also a subject of research now. Night shifts, less sleep and irregular schedules can affect melatonin and metabolism, which has been found to be linked to the risk of some cancers.
How can we protect ourselves?
Dr. Vijayakumar says that the objective is not to spread fear, but to increase awareness. Not every exposure results in disease because the body has strong defense mechanisms such as DNA repair and the immune system. But when small risks are added layer by layer, their importance increases. Regular sunscreen, better ventilation at home, reducing processed meats, limiting alcohol, getting enough sleep, and avoiding sitting for long periods of time can reduce risk over time. Cancer is often shaped not by any one big decision, but by years of habits. So small but consistent right choices can make a big difference in the long run.
