Colorectal cancer refers to cancer that occurs in the colon and rectum. It is one of the most common malignant tumors in the world. As far as our country is concerned, the incidence and mortality of the disease are also increasing year by year, ranking fourth among common tumors, and showing the characteristics that the eastern coast is higher than the western inland.
Moreover, the disease shows a tendency of younger age incidence, with more and more young people joining the colorectal cancer family, especially young people in cities, who are more susceptible to the disease. Relevant research shows that the occurrence of these conditions is mainly related to changes in people's lifestyle and dietary structure.
Colorectal cancer has an insidious onset and atypical symptoms . It is often found in the middle and late stages. Treatment is relatively difficult and the effect is relatively poor. Therefore, early detection of the signs of colorectal cancer and early intervention are very necessary for the treatment of colorectal cancer.
Generally speaking, for those who are over 45 years old and have a family history of rectal cancer, or a history of colorectal disease and genetic history, if these five signs appear during defecation, they should be alert, as it may be colorectal cancer.
. Blood in stool
Normal people’s stool is yellow and soft. For patients with colorectal cancer, their stool usually has blood stains. This is because the feces comes into contact with the tumor during its passage through the intestines, causing the tumor to bleed and remain in the feces. Therefore, if there are blood stains in the stool, you should be vigilant. It may be a warning of colorectal cancer.
. Changes in stool characteristics
The shape of normal people's stool is straight strips and relatively smooth; however, for patients with colorectal cancer, the shape of the stool changes due to the cancer occupying the corresponding position in the intestine, and may appear in a rhombus, flat strip, or other more angular shape.
And compared with ordinary defecation, their defecation is more difficult and the process is longer. Therefore, generally speaking, when the stool properties change, you should be alert to whether there is colorectal cancer or other lesions.
. Dull pain in the abdomen between defecation
Because the cancer has invaded the intestines, causing stool to not pass smoothly through the intestines, various abdominal pain and distension are prone to occur between defecations, and the defecation time is prolonged.
As the mass continues to grow, abdominal pain, bloating and other conditions will gradually worsen. In severe cases, the entire intestinal tract may even be blocked, causing cessation of defecation and breathlessness.
Therefore, when the abdomen is touched and accompanied by abdominal pain and bloating, you should consider whether you have colorectal cancer.
. Changes in defecation habits
Defecation habits have changed, specifically including defecation waiting time and changes in defecation form. Defecation waiting time means that you can tolerate defecation when you have the urge to defecate in the past, but you need to defecate immediately when you have the urge to defecate now.
The change in defecation pattern refers to the progression from regular bowel movements in the past to alternating forms of diarrhea and constipation. At first, the frequency of defecation increases in the early morning, and later it can progress to frequent defecation at night. And the gap between diarrhea is constipation. Once this alternating pattern of diarrhea and constipation occurs, be alert as it may be a sign of colorectal cancer.
5. Current status of the whole body predicts colorectal cancer
As we all know, tumors are consumptive diseases that are usually accompanied by atypical systemic symptoms.
The same is true for colorectal cancer. If you have symptoms such as fatigue, fatigue, weight loss, low-grade fever, and anemia recently, you should be alert after ruling out sub-health or recent excessive work intensity. It may be colorectal cancer.
You should go to the hospital for examination in time to clarify the situation; generally speaking, lesions can be quickly confirmed through digital rectal examination, fecal occult blood test , colonoscopy .
For others, you should also pay attention to preventing colorectal cancer in your daily life. Specifically, you can avoid high-fat, high-salt, low-fiber, and barbecue-type foods, pay attention to intestinal health on a daily basis, and treat intestinal diseases in a timely manner to fully prevent the occurrence of colorectal cancer.
In summary, this article describes the incidence of colorectal cancer and how to judge whether you have colorectal cancer through systemic symptoms such as blood in the stool, changes in the shape of the stool, changes in the excretion pattern, and abdominal pain and fatigue.
For people over the age of 45, it is recommended to have a regular physical examination every year. Young people should not relax their vigilance and eat less high-salt and high-fat barbecue foods in daily life to avoid colorectal cancer.
