“Well-known risk factors such as smoking, alcohol use, diet, and physical activity have not been increasing among younger adults in recent decades, except for obesity.”

CORROBORATED

Multiple web search results discuss the lack of increase in traditional risk factors (smoking, diet, physical activity) while highlighting obesity as a key exception. The MSN search result directly states that these factors 'have not been increasing... except for obesity.'

“Eleven cancers are becoming more common in young people in England, according to a major study, but the rise cannot be fully explained by changes in lifestyle.”

CORROBORATED

Two independent web search results confirm that a major analysis found eleven cancers becoming more common in young people in England. Both sources also mention that a full explanation for this rise remains elusive, suggesting lifestyle changes are not the sole cause.

“For most of these cancers, rates also rose in older adults, where cancer remains far more common overall.”

“But two cancers stood out: colorectal and ovarian cancer, which showed rising rates only in younger adults, suggesting that unique factors may be affecting this age group.”

SINGLE SOURCE

While one web search result mentions that 'Only bowel and ovarian cancers were increasing exclusively in the young,' another web search result mentions that 'two types — colorectal and uterine — are becoming both more common and more deadly among th.' The claim specifically names 'colorectal and ovarian,' which is supported by the first web search result, but the evidence is not consistently corroborated across multiple independent sources to confirm this exclusivity.

“The 11 cancers identified as increasing in younger adults are: Breast cancer, Colorectal (bowel) cancer, Pancreatic cancer, Kidney cancer, Liver cancer, Gallbladder cancer, Thyroid cancer, Multiple myeloma (a type of blood cancer), Oral cancer, Endometrial cancer, Ovarian cancer.”

CORROBORATED

Multiple web search results list the 11 cancers identified in the study, naming thyroid, multiple myeloma, liver, kidney, gallbladder, pancreatic, womb lining (or endometrial), mouth, and ovarian, alongside bowel and breast cancers. The list provided in the claim matches the details found in the search results.

“Obesity was the main exception. It has risen steadily across adult age groups and remains an important contributor to cancer risk.”

INSUFFICIENT EVIDENCE

Although the claim is a key conclusion of the original article, no specific evidence was retrieved from the web search or Wikipedia to confirm that obesity 'has risen steadily across adult age groups' or that it 'remains an important contributor to cancer risk' in a manner that corroborates the claim's strong assertion.

“The researchers found that obesity alone did not explain the overall rise in cancer among younger adults.”

INSUFFICIENT EVIDENCE

This claim is a summary conclusion drawn by the original research team. No direct evidence or corroborating source was found in the provided web search results to confirm that 'Obesity alone did not explain the overall rise in cancer among younger adults.'

“Even for cancers associated with higher body weight, such as bowel, kidney, pancreatic, liver, gallbladder, and womb cancers, the increase could not be fully accounted for by rising obesity.”
