  • Latest research says young adults have higher chances of having colorectal cancer
  • Risk is higher in those born in 1990
  • The research also has stats for other kinds of cancer

Americans born in 1990 have double the risk of colon cancer and quadruple the risk of rectal cancer than those born around 1950, a new study suggests.

The study found that colorectal cancer is on the rise among young and middle-aged adults in their early 50s. Rectal cancer is growing particularly fast among people younger than 55, with 30 percent of diagnoses in people under 55.

“Trends in young people are a bellwether for the future disease burden,” said Rebecca Siegel, of the American Cancer Society and lead author of the study that appeared in the Journal of the National Cancer Institute.

“Our finding that colorectal cancer risk for millennials has escalated back to the level of those born in the late 1800s is very sobering. Educational campaigns are needed to alert clinicians and the general public about this increase to help reduce delays in diagnosis, which are so prevalent in young people, but also to encourage healthier eating and more active lifestyles to try to reverse this trend.”

Researchers note that rates of colorectal cancer have been falling since the 1980s with an even steeper decline in the past decade, which has been caused by more screening.

But they wanted to find out why some studies have shown a rising rate among people under 50 for whom screening is generally not done. For their study, researchers looked at cases of colorectal cancer in people over 20 from 1974 to 2013. There were 490,305 cases.

The data showed the rates of colon cancer initially decreased after 1974, but then grew by one or two percent from the mid-1980s to 2013 among adults aged 20 to 39. For people aged 40 to 54, the rates increased between .5 percent and one percent from the mid 1990s to 2013.

For rectal cancer, the increases were greater, with rates rising about three percent per year from 1974 to 2013 in adults aged 20 to 29. For adults between 30 and 39, there was a similar rise from 1980 to 2013. For adults between 40 and 54, rates increased by two percent from the 1990s to 2013.

Rates for adults older than 55 has been declining for about 40 years, researchers said.

Researchers say the results could change the age at which screening for colorectal cancer starts and cite 10,400 cases diagnosed in people in their 40s plus 12,800 cases in people in their early 50s.

“These numbers are similar to the total number of cervical cancers diagnosed, for which we recommend screening for the 95 million women ages 21 to 65 years,” Siegel said. VOA

Cigars, Pipes Tied To Same Risks As Cigarettes

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use

  • Cigarettes are not the only tobacco products which can cause death
  • Other tobacco products like cigars and pipes are just harmful
  • All these tobacco products can cause cancer

Cigarettes are not the only type of tobacco products that can lead to premature death or fatalities from smoking-related cancers, a U.S. study confirms.

While people who exclusively smoke cigarettes have twice the risk of premature death from all causes compared to people who avoid tobacco altogether, exclusive cigar smokers have a 20 percent higher risk of early death, researchers report in JAMA Internal Medicine.

When it comes to fatalities from specific cancers that have been tied to tobacco use, cigarette smokers have four times the risk of people who never used tobacco, but cigar smokers are 61 percent more likely to die of these cancers and pipe users have 58 percent higher odds.

“We knew exclusive users of cigars and pipes were at greater risk of disease than people who do not use tobacco,” said lead study author Carol Christensen of the U.S. Food and Drug Administration’s Center for Tobacco Products. “However, this study provides information that reflects today’s patterns of tobacco use.”

These data “underscore the importance of complete quitting,” Christensen said by email.

For the study, researchers examined nationally representative survey data, collected starting in 1985, from 357,420 participants who were followed through 2011.

Overall, 203,071 people, or about 57 percent, never used tobacco at all. Another 57,251 participants were current daily cigarette smokers, while 9,414 said they had a less frequent habit and 77,773 were former cigarette smokers.

In addition, 531 people were current daily cigar smokers, while 608 individuals used cigars less frequently and 2,398 had quit.

For pipes, 1,099 participants had a current daily habit, while 78 people used pipes less often and 5,237 had quit.

During the study period, 51,150 people died of all causes.

With a daily cigarette, cigar or pipe habit, people had an elevated risk of death from tobacco-related cancers including malignancies of the bladder, oesophagus, larynx, lung, mouth and throat, and pancreas.

Nondaily users

Even with a nondaily cigarette habit, people were more than six times more likely to die of lung cancer than individuals who never used tobacco. They also had more than seven times the risk of dying from a chronic obstructive pulmonary disease, more than four times the odds of death from oral cancers, and 43 percent higher odds of death from a circulatory system disorder.

Current cigar smokers had more than three times the odds of dying of lung cancer, and for current pipe smokers, the risk was 51 percent higher, compared with never-smokers.

The results were limited, however, by the relatively small numbers of cigar and pipe smokers in the sample, the authors noted.

Another limitation was that survey questions about tobacco use changed over time and didn’t determine how often nondaily smokers might have used cigarettes, cigars or pipes.

Even so, the results suggest that doctors may need to broaden how they discuss smoking with patients to make sure people understand they’re at risk even when they don’t have a daily habit, said Dr. Michael Ong of the University of California-Los Angeles and VA Greater Los Angeles Healthcare System.

“Patients often do not associate the occasional use of cigar or pipes with health risks, but this study shows that current, particularly daily, cigar use is associated with increased overall risk of death,” Ong, who wasn’t involved in the study, said by email.

Doctors also need to broaden their message about smoking and cigarettes to include other tobacco products that are becoming more popular, said Judith Prochaska, a researcher at Stanford University in California who wasn’t involved in the study.

Traditionally, doctors have asked just whether people smoked cigarettes, but they should instead be questioning patients more broadly about tobacco use, Prochaska said by email.

“The tobacco landscape has been changing dramatically,” Prochaska added. “While cigarettes remain the primary tobacco product used, cigars, smokeless tobacco, e-cigarettes, hookah, and even pipe tobacco have seen gains in use, while cigarette use in the U.S. has been declining.” VOA
