"It Couldn't Happen to Me": 2030s Overlooking Colorectal Cancer, Surging 125% in 5 Years

[Anchor]

In recent years, the number of colorectal cancer patients among those in their 20s and 30s has been increasing significantly. Reports indicate that the figure has more than doubled compared to five years ago. Because colorectal cancer often lacks distinct symptoms in its early stages, it is easy to overlook. We take a closer look at the warning signs and prevention methods.

According to recently released National Cancer Registration Statistics, the number of newly diagnosed colorectal cancer patients among individuals aged 20 to 39 surged by over 125% over a five-year period, jumping from 864 in 2018 to 1,948 in 2023.

Compared to increases of 42.9% for those in their 40s and 9.8% for those in their 50s over the same period, the upward trend among the 2030 generation is exceptionally steep.

Of course, the absolute number of patients remains much higher among middle-aged and older adults. However, the real problem is that people in their 20s and 30s do not even consider the possibility that they might have colorectal cancer.

Given their young age, combined with the fact that colorectal cancer itself initially presents with virtually no special symptoms, it is easily missed.

Looking at the symptoms, they include unexplained abdominal pain and bloating, a feeling of incomplete evacuation, alternating bouts of constipation and diarrhea, anemia, fatigue, and weight loss.

Furthermore, when younger individuals notice bright red blood on toilet paper due to rectal bleeding, most assume it is because of something they ate the day before or simply hemorrhoids.

"Lately, there are occasional cases where people simply assume it is hemorrhoids, only to undergo an examination and discover cancer. Of course, hemorrhoids are the most common cause of rectal bleeding in young patients. However, the important point is that hemorrhoids are not the only cause of rectal bleeding."

Why is it suddenly increasing specifically among those in their 20s and 30s?

"There is considerable and clear evidence linking the consumption of processed meats, such as ham, sausages, and bacon, to an increased risk of colorectal cancer. Conversely, studies have shown that diets rich in dietary fiber, such as vegetables, fruits, and whole grains, help lower the risk. The problem is that frequently consuming foods like processed meats reduces beneficial substances produced by good bacteria in the gut, creating an environment that can trigger inflammation or irritation in the intestines. When these changes are repeated over a long period, it can foster an environment where colorectal cancer is more likely to develop. Because of poor dietary habits, obesity rates rise, and a lack of exercise further increases obesity. Consequently, when the gut environment deteriorates as a result, the risk of incidence increases."

Amid this situation, the current target demographic for colorectal cancer screening under the national health screening program is men and women aged 50 and older.

While the government lowered the screening age this year, it was only reduced to 45.

"Healthy individuals in their 20s do not need to undergo regular colonoscopies simply because there are a lot of young colorectal cancer cases lately, provided they have no symptoms. If unusual symptoms that differ from usual persist or recur, it is important to accurately identify the cause. Since a single symptom alone cannot definitively confirm cancer, if you experience symptoms or changes in your bowel habits compared to before, you should consult a doctor first and undergo a colonoscopy if deemed necessary based on the physician's judgment."

Then, instead of getting a colonoscopy right away, what should people do to prevent colorectal cancer in their daily lives?

[Interview: Seo Ji-hyun / Professor of Surgery, Inha University Hospital]
"The most realistic prevention method for the young 2030 age group is lifestyle management. First, reduce excessive consumption of processed meats. Second, consume adequate amounts of dietary fiber, such as vegetables, fruits, and whole grains, without overdoing it. Third, exercise regularly and maintain an appropriate weight. Fourth, quit smoking and reduce alcohol consumption."
