A medical oncologist has identified five common household products he personally avoids due to potential links to cancer, stressing that these are precautionary measures rather than definitive causes for alarm.
Dr. Sudarson Vishnu Kollimuttathuillam, an oncologist and hematologist, suggests that while many products are rigorously regulated, reducing exposure to certain substances is a sensible step when easy alternatives exist. He notes that for some items, the evidence linking them to cancer is clear, while for others, research is ongoing.
Fragranced Products and Air Fresheners
Dr. Kollimuttathuillam generally avoids plug-in air fresheners and minimizes the use of heavily fragranced household and personal care items. He explains that some scented products can release volatile organic compounds (VOCs) into indoor air. While the evidence directly linking the normal use of these products to cancer is limited, he prefers to avoid unnecessary exposure. Simple alternatives include opening windows, improving ventilation, or opting for less fragranced products.
Damaged Plastic Containers
The oncologist also refrains from using plastic food containers that are scratched, cloudy, warped, or otherwise damaged. He recommends using glass or ceramic alternatives when reheating food or storing it, and ensuring any plastic containers used are specifically designed for heating. While small amounts of chemicals can migrate from plastic into food, there is no reliable evidence that storing food in plastic causes cancer in people. Replacing old or damaged containers is presented as a simple precautionary step.
Naphthalene Mothballs
Traditional mothballs containing naphthalene are another item Dr. Kollimuttathuillam avoids. Naphthalene can turn into a vapor at room temperature, leading to exposure through breathing the air where it is used. It has been classified as possibly carcinogenic to humans, primarily based on animal studies, though human evidence is limited. He suggests non-chemical alternatives like keeping storage areas clean and washing clothing before storing it. In the UK, naphthalene mothballs are no longer permitted for household use.
Strong Household Cleaners
While most household cleaners are considered safe when used as directed, Dr. Kollimuttathuillam opts for simpler products. Some cleaners and solvents can release chemicals into the air or cause irritation to the skin, eyes, and respiratory system, particularly with frequent use or in poorly ventilated areas. The greatest health concerns are generally linked to repeated or occupational exposure. He advises following instructions carefully, ensuring good ventilation, and never mixing cleaning products unless specifically indicated as safe.
Unnecessary Pesticides and Insecticides
Minimizing the unnecessary use of pesticides and insecticides in and around the home is also a priority. Some pesticides have been studied for potential associations with cancer, though stronger concerns typically involve individuals with higher or repeated exposures, such as occupational exposure. Dr. Kollimuttathuillam prefers to start with non-chemical pest control methods when practical and only uses pesticides when necessary, following directions carefully and avoiding overuse.
Dr. Kollimuttathuillam emphasizes that while taking steps to minimize potential risks is advisable, it is important to maintain perspective. He highlights that fundamental lifestyle choices such as not smoking, maintaining a healthy weight, regular exercise, limiting alcohol consumption, protecting skin from excessive UV exposure, and undergoing recommended cancer screenings are far more significant for reducing cancer risk than worrying about everyday household products.
