What are the early symptoms of colon cancer?

Intestinal 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 or late stage. For some intestinal cancers, the time period from occurrence to discovery can be as long as more than ten years. Let's learn about this knowledge together.

According to medical research, cancer develops from genetic mutations. When the genes mutate to a certain extent and encounter certain inducements, such as fatigue leading to low immunity, people will develop cancer. However, slow development does not mean low mortality. If not treated in time, the mortality rate can reach 100%!

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.

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.

Early detection of colorectal cancer: regular check-ups are essential

Since colorectal cancer is a type of cancer with hidden early symptoms and can be easily confused with a variety of diseases, how can it be detected early? Wang Xikun recommends that people should have blood drawn every six months or even three months for tests such as carcinoembryonic antigen and tumor factor tests. Such tests can detect which tissue has early cancer. If problems are found, they can be carefully examined in the corresponding department for early diagnosis and treatment.

In addition, if you find blood in your stool, you can go to the hospital's surgery department for a rectal digital examination, which can largely determine whether you have rectal cancer. If you have bloody stools, mucus in your stools, changes in bowel habits, alternating diarrhea and constipation, etc., it is best to do a colonoscopy and abandon the fluke mentality. You should know that this is currently the most effective means of early diagnosis of colorectal cancer. People at high risk of colorectal cancer - those with colorectal polyps and ulcerative colitis - should undergo regular reexaminations or general examinations.

Of course, to prevent colorectal cancer, you still need to have a healthy lifestyle, don't eat too much refined food, eat less meat, eat more starch and fiber, reduce environmental pollution, and keep exercising. The above is some knowledge about the early symptoms of colorectal cancer that we prepared for you today. I hope it will be helpful to you.
