Millennials Twice as Likely to Develop Obesity-Related Cancers, Says Study


MONDAY, Feb. 4, 2019 (HealthDay News) - As more young American adults struggle with extra weight, they are paying an even steeper price as the rates of obesity-related cancers rise in this age group.

"The future burden of these cancers could worsen as younger cohorts age, potentially halting or reversing the progress achieved in reducing cancer mortality over the past several decades".

To try to curb the trend of rising cancers among the obese, Jemal thinks that primary care doctors need to screen all their patients for obesity.

Berger said, If you are obese, you are at a higher risk of cancer.

For instance, pancreatic cancer is traditionally most common in people over the age of 65.

In addition, communities can provide more opportunities for people to exercise by creating bike and walking paths.

In contrast to the other obesity-related cancers, the risk of developing breast cancer generally remained unchanged in younger generations.

These included multiple myeloma, colorectal, uterine corpus, gallbladder, kidney and pancreatic cancers.

The survey revealed that the obesity-linked cancers in young adults have been on the rise between 1995 and 2015, affecting both women and men, nearly equally.

It's not possible to definitively attribute the recent cancer increases to obesity - but the new report notes that the upticks in cancer for young people coincided with a doubling in rates of childhood and adolescent obesity between 1980 and 2014, making weight a likely contributor.

Americans aged 25 to 29 had the greatest increases in kidney cancer, with an average annual increase of 6.23%, while people aged 30 to 34 had the largest increase in multiple myeloma, at 2.21%.

However, although the rates are increasing faster among young adults, the overall rate is lower than among older adults, according to the report.

The current study did not include data on obesity and can only infer a link between obesity and rising cancer rates, says Schwartz. Of course, obesity is only one factor - the environment, genetics and other issues also play roles, the BBC points out.

Most epidemiological studies have focused on older populations so the effect on cancer risk of excess bodyweight in early life, or of weight gain in young adulthood, is not well understood.

Obesity-related cancers - including bowel, womb and pancreatic - are significantly increasing in under-50s, suggesting numbers will soar in decades to come.

Obesity is one of the most preventable causes of cancer.

'Younger generations are experiencing earlier and longer-lasting exposure to excess fat and to obesity-related health conditions that can increase cancer risk'.

Professor Aranda continued, "While it is important for people to look after themselves by doing regular physical activity and eating a balanced diet, Australia's obesity problem can not be placed entirely on the individual's shoulders".

"Changes have to happen at a societal level", she suggested.

"Our results showed, compared with persons born circa 1950, persons born circa 1985 had from 1.6 to 4.9 times higher risks, depending on cancer types", Dr.

The study has been published in the International Journal of Cancer.

The rates of new cancer cases and cancer deaths have fallen in the USA over the past few decades.
