A GP has shared the steps she takes in her own home she claims could lower your risk of cancer. This includes cutting down everyday exposure to substances she says are linked to long-term harm.

She said that while no home can ever be completely risk-free, reducing daily exposure to toxins may help lower cumulative danger over time. Doctor Asiya Maula, a GP at The Health Suite, said much of it comes from things people assume are harmless.

“Cancer risk isn’t about one single thing,” she said. “It’s about what the body is dealing with every day, for years or even decades.” She shared some practical ways people can reduce their long-term risk at home.

Improve indoor air quality

Indoor air can often be more polluted than outdoor air due to cooking fumes, candles, sprays and poor ventilation. “Long-term exposure to indoor air pollutants may contribute to inflammation in the body,” Dr Maula said, adding that opening windows daily and using extractor fans can make a real difference.

Be cautious with cleaning products

Many household cleaners contain harsh chemicals designed to kill bacteria and break down grease. “These products exist to destroy biological material,” she said.

“Repeated exposure in enclosed spaces may irritate the body over time. ” Dr Maula recommended milder, fragrance-free products where possible.

Reduce pesticide use at home

Pesticides aren’t just used on farms - they’re also found in homes and gardens, often in sprays and treatments, she said.

“They’re designed to kill living organisms,” Dr Maula said. “The concern is what low-level exposure might be doing to human cells, particularly for children.” She added that washing fruit and vegetables thoroughly and limiting chemical pest control indoors can help.

Cut back on ultra-processed food

What people store and cook at home matters too, with ultra-processed foods linked to obesity, insulin resistance and chronic inflammation - all established cancer risk factors.

Dr Maula stressed the aim isn’t perfection. “It’s about reducing the overall toxic load,” she said. “Small changes, done consistently, can add up over time - and making your home a lower-exposure environment is one practical way to protect long-term health.”
