What are the main factors that are easily overlooked in colorectal cancer?

What are the main factors that are easily overlooked in colorectal cancer? I believe many people have this question. Many patients ignore the early symptoms of the disease, which leads to the aggravation of their condition. Let us now learn about the factors that are easily overlooked in colorectal cancer .

1. The lack of obvious early symptoms of colorectal cancer is one of the factors that colorectal cancer is ignored. Colorectal 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. When symptoms appear, the cancer is generally in the middle and late stages. The time period from the occurrence to the discovery of some colorectal cancers can be as long as more than ten years. According to medical research, cancer develops from gradual genetic mutations. When the gene mutation reaches a certain level and encounters certain inducements, such as fatigue leading to low immunity, people will develop cancer.

2. Intestinal cancer is easily confused with many diseases. There are several main diseases whose symptoms are easily confused with intestinal cancer, such as hemorrhoids, anal fissures, intestinal polyps, dysentery, gastric ulcers, colitis, etc. They are all easily confused with intestinal cancer because of blood in the stool, causing confusion. Among them, 50% of patients with rectal cancer were misdiagnosed as hemorrhoids in the early stage. Although both have blood in the stool, there are actually differences. Intestinal cancer patients will have abdominal distension and abdominal pain due to intestinal obstruction. When the tumor ruptures, the stool will be mixed with 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, and they often excrete black or tarry stools. In addition to the different stools, the accompanying symptoms are also different. While intestinal cancer patients excrete mucus and thick blood in the stool, their bowel habits will change, sometimes diarrhea, sometimes constipation. This is because the growth of the tumor affects the normal physiological function of the intestine, causing spasms and contractions. Patients with hemorrhoids have visible protrusions in the anus when defecating. Patients with anal fissures have anal pain during defecation, while patients with intestinal polyps do not have abdominal pain. Patients with dysentery will have 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.

3. Neglecting health due to work stress is also a factor that is often overlooked in colorectal cancer. 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 things in common: 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. Moreover, young people have strong immune function and the body's resistance reaction is fierce, which will stimulate the growth rate of cancer cells.

The above is an introduction to the neglected factors of colorectal cancer. Through the above content, have you learned some relevant knowledge about colorectal cancer? I hope the above content can be helpful to you, and I also hope that patients can actively treat and recover soon!
