People According to a new analysis, those who are overweight in early and middle age are less likely to survive some cancers.
Researchers have studied the effect of BMI (body mass index) scores among people aged 20 to 50 on survival in breast and bowel cancer at a later age.
They used data from a study that tracked data from more than half a million people Europe since 1992.
Participants were followed for an average of nine years to see if they had died of breast cancer or bowel cancer.
The study included 1,620 people diagnosed with breast cancer and 1,045 patients with colorectal cancer.
During the follow-up period, 377 breast cancer patients and 509 bowel cancer patients died.
Statistical analysis showed that people with higher BMI levels in early and middle age were more likely to die from breast or bowel cancer compared to cancer patients who had lower BMI.
The researchers found that for every extra point in a person’s BMI, the risk of dying from bowel cancer increased by 6%.
And for each additional BMI point among breast cancer patients the risk of death increased by 4%.
The authors of the article, published in the journal BMC Cancer, wrote: “The cumulative effects of higher BMI levels in early and mid-adulthood (ages 20 to 50) have been associated with poorer survival in patients with breast and colorectal cancer.”
The World Cancer Research Foundation, which partially funded the study, said the importance of maintaining a healthy weight “cannot be overestimated.”
Dr Panagiota Mitru, director of research and innovation at the World Cancer Research Foundation, said: “In addition to the wealth of research on the two common forms of cancer, this study shows that exposure to higher body weight in early and middle age plays an important role. involved in cancer prognosis.
“We know that maintaining a healthy weight throughout life is not always easy, but the importance of it cannot be overstated.”
