'Shocking' rise in obesity-related cancers among young adults

"Our findings expose a recent change that could serve as a warning of an increased burden of obesity-related cancers to come in older adults", explained Ahmedin Jemal of the American Cancer Society, and the new study's co-author.

Experts said more research is needed to explore what is causing the rising rates because this study does not prove obesity is the only reason.

In contrast to obesity-related cancers, rates of most of the 18 non-obesity related cancers did not increase among young adults during the study period.

This found that across Europe the rate of new cases of colon cancer among people aged 20-39 has risen by 7.4 per cent each year between 2008 and 2016, with incidence of rectal cancer also increasing.

"Although the absolute risk of these cancers is small in younger adults, these findings have important public health implications", Ahmedin Jemal, ACS's scientific vice president of surveillance & health services research and an author of the report, said in a statement.

Obesity is an emerging risk factor that is driving a number of important cancers, said Elizabeth Platz, a scholar in cancer prevention at Johns Hopkins Bloomberg School of Public Health, in Baltimore.

Incidence of multiple myeloma and cancers of the colorectum, uterine corpus, gallbladder, kidney, pancreas, and thyroid increased in younger adults (25 to 49 years).

A sharp increase in obesity-linked cancers among young adults in the United States could foreshadow a reversal in the overall decline in cancer mortality, researchers warned Monday.

Obesity has already been linked to rising rates of type 2 diabetes, heart disease and knee replacements.

For example, the average annual increase for pancreatic cancer was more than four percent for patients ranging in age from 25 to 29, but less than one percent for those age 40 to 44.

Overall, cancer-related deaths in the United States have fallen 27 percent in the past 25 years, mostly because fewer people are smoking and developing lung cancer, according to the most recent cancer statistics, published January 8, 2018, in the journal CA: A Cancer Journal for Clinicians (from the American Cancer Society).

The age group with the greatest increased risk of developing multiple myeloma was those aged between 30 and 34.

Excess body fat is known to increase the risk of certain cancers.

Researchers say that these cancers normally get detected in patients in their 60s and 70s. Only a third of people who are obese report receiving a diagnosis or weight loss counselling.

That research included data from national cancer registries of 20 European countries, including the UK, Norway, Slovenia and Germany.

"Obesity during childhood actually is a major predictor of adult obesity", Chang said, "I think it highlights the importance of reducing the rates of obesity through better diet, better and more exercise".
