Why is early stage colorectal cancer easily ignored?

In recent years, colorectal cancer has become one of the major diseases that endangers society and human health, and it has brought great pain and distress to humans. In order to reduce the incidence of colorectal cancer, we humans should understand the reasons why early colorectal cancer is ignored:

Early symptoms of colorectal cancer are not obvious

Colon cancer is mostly adenocarcinoma and squamous cell carcinoma. From a pathological point of view, these two types of cancer are moderately toxic and grow relatively slowly compared to other cancers. There may be no obvious symptoms in the early stage, even for many years, and it is difficult to detect. By the time symptoms appear, the cancer is generally in the middle or late stage. One of Dr. Wang's patients is a woman in her 50s. One day, she had intestinal obstruction after eating leek dumplings. When she went to the hospital for a checkup, she was found to have colon cancer. She usually felt good about herself. This time, colon cancer was discovered thanks to the fact that leeks are crude fibers that cannot pass through the narrowed intestines caused by cancer! Therefore, some colon cancers can take more than ten years from the onset to discovery.

Bowel cancer can be easily confused with many diseases

According to the survey data of Guangzhou Cancer Hospital, about 30% to 40% of colorectal cancer patients are misdiagnosed due to the negligence of doctors and patients themselves. There are several diseases whose symptoms are easily confused with colorectal cancer, such as hemorrhoids, anal fissures, intestinal polyps, dysentery, gastric ulcers, colitis, etc. They are easily confused with colorectal cancer because of blood in the stool, causing confusion. Among them, 50% of rectal cancer patients are misdiagnosed as hemorrhoids in the early stage.

Although both have blood in their stool, there is actually a difference. Patients with colorectal cancer will have abdominal distension and pain due to intestinal obstruction. When the tumor ruptures, the stool will contain pus and blood, and the stool and blood will be mixed. However, the stool of patients with hemorrhoids, anal fissures, and intestinal polyps is not mixed with blood, but attached to the surface of the stool, and the blood is bright red or relatively fresh. The stool of patients with gastric ulcers is significantly different from that of patients with enteritis. They often have black or tarry stools.

In addition to the difference in stool, the accompanying symptoms are also different. While colorectal cancer patients excrete mucus, thick blood in their stools, their bowel habits will change, sometimes with diarrhea and sometimes with constipation. This is because the growth of the tumor affects the normal physiological function of the intestine, causing spasms and contractions. When patients with hemorrhoids have bowel movements, protrusions can be seen in the anus. People with anal fissures have anal pain during bowel movements, while patients with intestinal polyps do not have abdominal pain. Patients with dysentery will have a fever, abdominal pain, and tenesmus, that is, they have the urge to defecate and are anxious to go to the toilet but always feel that they cannot defecate completely. Patients with ulcers have long-term, periodic pain in the upper abdomen and frequent belching, acid reflux, and nausea.

Work stress and neglect of health

In recent years, the medical community has noticed that colorectal cancer is becoming younger and younger, especially some elites around 40 years old are prone to colorectal cancer. They have several common points: irregular diet due to busy work, disrupted digestive tract physiological rhythm, poor intestinal function; high mental stress affects gastrointestinal function and changes in bowel function; excessive drinking, damp heat in the intestines, poor bowel movements. In addition, young people have strong immune function and the body's resistance reaction is fierce, which will stimulate the growth rate of cancer cells.

Like many Zhejiang businessmen who rose from the grassroots, Wang Junyao is bold and innovative, practical, hardworking, determined and unyielding. "He works very hard and his level of hard work is unmatched by others."

The above are the reasons why early colorectal cancer is ignored.
