How everyday products could be raising cancer risks

As Cancer Awareness Day highlights the importance of prevention, experts urge B’luru residents to make informed choices in their daily lives to reduce the risk

As we observed Cancer Awareness Day on November 7, the discussion around carcinogenic agents in everyday products became even more critical. Recent reports in Bengaluru highlight that many of the items we consume, including cakes, cotton candy, masala packets and processed foods, may contain harmful substances that increase the risk of cancer. With this in mind, it is important to empower consumers to make informed choices about the products they buy, particularly when it comes to food and household items. Dr Raghunath CN, a Consultant Pediatrician at Sagar Hospitals, in Bengaluru, offers crucial advice: “It would be better to stop drinking water from plastic containers as they release polyethylene (a synthetic resin that is the most commonly used plastic) when exposed to heat, which can be carcinogenic.”Another area of concern is the use of plastic materials in microwaves.

Reheating food in plastic containers even those labelled microwavesafe can release harmful chemicals, he claims. “It’s best to avoid using plastics for reheating food,” Dr. Raghunath advises. “The quality of plastic can degrade over time, increasing the risk of harmful exposure. Most plastics, even those that seem durable, have a shelf life and can lose their safety features with extended use.” So, switching to safer alternatives, such as glass or ceramic, for reheating food is a wise decision. Processed foods, that are widely available in Bengaluru, particularly those containing artificial food colouring, MSG (Ajinomoto) and preservatives, should also be avoided. These chemicals are known to increase cancer risk. Fast food, a regular part of many people's diets, is particularly concerning. The oils used in fast food are often linked to harmful health effects. Palm oil, commonly imported from Malaysia, has been associated with various health risks, he claims. The overuse of antibiotics and steroids in poultry and fish farming is another issue worth noting.

“Chickens raised with hormones grow faster and fish raised in artificial conditions often contain high levels of antibiotics,” says Dr. Raghunath. “These practices contribute to antibiotic resistance and other health risks.” When buying meat, eggs, or fish, it’s better to choose fresh products from trusted sources, he says. Dr Sneha Kommineni, Consultant in Medical Oncology at Aster RV Hospital, Bengaluru emphasises the importance of consumer awareness: “Carcinogenic substances can be naturally present or introduced during food processing, cooking, or contamination. To make healthier choices, start by reading food labels carefully. Opt for products with familiar ingredients and limit items high in sugar, sodium and unhealthy fats.” Healthier cooking methods, such as steaming, baking, or grilling at lower temperatures, can help reduce the formation of carcinogens produced during frying.
