Marriage could help protect against cancer, according to a major new study.

Scientists found that people who never tie the knot are significantly more likely to develop the disease compared to those who are married, divorced or widowed.

Researchers at the University of Miami analysed medical records from four million Americans diagnosed between 2015 and 2022 – and uncovered a striking trend.

Women who had never married were 85 per cent more likely to be diagnosed with cancer than those who had, while never-married men faced a 70 per cent higher risk than husbands.

The study suggests that emotional support and lifestyle factors linked to relationships could play a key role.

Study author Dr Frank Penedo said: “It’s a clear and powerful signal that some individuals are at a greater risk.

“It means that if you’re not married, you should be paying extra attention to cancer risk factors, getting any screenings you may need and staying up to date on health care.”

Experts believe having children – more common among married couples – may help lower the risk of certain cancers, including womb and ovarian cancer.

They also say partners may encourage healthier habits and push each other to seek medical help earlier – something that can be crucial for survival.

Previous research has shown married people are often diagnosed sooner and have better outcomes after treatment.

However, researchers stress that marriage itself is not a magic shield.

Dr Penedo noted the link may partly be because healthier people are more likely to marry in the first place.

In England and Wales, around seven per cent of women and 11 per cent of men remain unmarried by the age of 65 – a figure that is rising.

Scientists say the findings highlight the importance of regular check-ups and awareness – regardless of relationship status.
