An analysis released Monday by the American Cancer Society (ACS) reveals that obesity-linked cancers are on the increase among young adults in the United States, a trend which could stifle the progress made in reducing cancer mortality over the last few decades. Millennials At Risk Of Obesity-Related Cancer The researchers arrive at the conclusion after they studied public data on invasive cancer among individuals ages 25 to 84 years from 1995 to 2014.
The authors called for more aggressive screening for obesity by front-line doctors, and called on them to warn patients about the cancer risk of being seriously overweight. The investigators looked at 30 of the most common cancer types, including 12 obesity-related cancers, diagnosed from 1995 through 2014.
On the other hand, the obesity-linked cancers that have been revealed as the most prevalent in the recent survey were pancreatic cancer, colon cancer, a rare form of bone marrow cancer (known as multiple myeloma), and a few others. But this study found that there was a significant increase of these cancers in young adults in the US.
Ahmedin Jemal, senior author of the study, said: 'Although the absolute risk of these cancers is small in younger adults, these findings have important public health implications. He points out that five of the six cancers on the rise in younger adults - colorectal, uterine, gallbladder, kidney and pancreatic cancer - are treated surgically.
For the study, the researchers analyzed data from 25 state cancer registries that cover 67 percent of the USA population. The numbers suggest that millennials have roughly twice the risk of developing these cancers as baby boomers did at the same age.
Across the six cancer types, the annual increase ranged from 0.4 per cent in uterine corpus cancer to 3.0 per cent in kidney cancer amongst 45 to 49-year-olds, and from 1.4 per cent for multiple myeloma up to 6.2 per cent in kidney cancer in 25 to 29 year-olds.
Morning Rounds: Measles outbreak and vaccine safety
However, he said an older person with a weaker immune system could have a higher chance of a risky infection if not vaccinated. As many as 1 out of every 20 children with measles will get pneumonia, which can also be deadly, the agency reports.
Berger said, If you are obese, you are at a higher risk of cancer. These changes include genetic flags and markers - epigenetic modifications - that increase cancer risk and may remain long after weight loss. If trends continue as projected carrying excess weight could cause even more cases of cancer in women than smoking within 25 years.
Professor Sanchia Aranda, CEO Cancer Council Australia said, "With more than two thirds of adults considered overweight or obese, and almost half insufficiently active, these results show we have the potential to prevent a significant number of cancers in Australia and potentially save thousands of lives".
New Cancer Council Australia funded research has shown over 200,000 cancer cases could be avoided in Australia over the next 25 years if all Australian adults maintained a healthy weight and met the physical activity guidelines for cancer prevention.
