The first question: What are the manifestations of colorectal cancer? Which is the symptom of colorectal cancer

For now, it is more realistic and urgent to pay more attention to secondary prevention, that is, to detect colorectal cancer as soon as possible. Therefore, the age-appropriate and high-risk population should take the initiative to screen for colorectal cancer (how to screen, detailed in a separate article).

And if there are some symptoms, of course, we must pay more attention to it, seek medical treatment in time, find out the cause, and make the diagnosis clear. However, most of the early stages of colorectal cancer do not have obvious symptoms, and clinical symptoms do not appear until the disease has progressed to a certain extent, but it may not be the early stage.

Pay special attention to the following aspects of performance. Once it occurs, you must see a doctor in time without delay.

 

The first thing to pay attention to:

bowel irritation and changes in bowel habits. To put it bluntly, it means that the number of times of defecation is very frequent, and the toilet is always used, and there is unexplained diarrhea (diarrhea) or constipation, or alternating constipation and diarrhea. Anus bulge, abdominal discomfort, pain, bloating, and so on.

 

The second thing to pay attention to:

blood in the stool, that is, the stool is bloody, sometimes bright red, sometimes dark red, usually intermittently, sometimes mucus blood in the stool, and sometimes direct discharge of blood.

 

The third thing to pay attention to:

the appearance of a lump in the abdomen, or the appearance of intestinal obstruction (abdominal pain, bloating, unresolved stool, vomiting, etc.), which usually means that the tumor has developed to a certain degree, and it may not be early.

 

The last thing to say is that if there is unexplained anemia or weight loss, fatigue, etc.: to find out the cause, if it is caused by cancer, it may usually be late.

 

Remind everyone not to be seated in the same seat. The above symptoms are not necessarily colorectal cancer. Without the above symptoms, you may already have colorectal cancer. Therefore, you cannot simply judge whether you have colorectal cancer and whether you have colorectal cancer, early or late based on the symptoms mentioned above. , The above is just a reference, remind everyone to go to the hospital for examination in time if there is abnormal performance, in order to confirm or rule out the diagnosis.

 

 

 

The second question: How to diagnose colorectal cancer? Principles of Diagnosis and Treatment of Colorectal Cancer

How is colorectal cancer diagnosed?

The diagnosis of colorectal cancer is mainly based on the above findings and the doctor’s physical examination (such as the doctor’s abdominal palpation, digital rectal examination), there is a preliminary suspicion, and then some necessary examinations, such as colonoscopy, X-ray examination, and ultrasound examination , CT or magnetic resonance examination, blood sampling to check tumor markers, etc.

The most important one is to perform colonoscopy and take a biopsy to confirm the pathological diagnosis. Pathological diagnosis is the gold standard for the final diagnosis. Perform staging inspections to understand the metastasis and spread of tumors.

 

There may be people who are concerned about the treatment of colorectal cancer. The professionalism in this area is relatively strong, and the content is also very detailed. Here is just a brief introduction to the general principles of treatment. The main treatment for colorectal cancer is surgery, which is the main means to fight for a cure.

Surgery mainly includes radical surgery, palliative surgery or reduction surgery (palliative surgery to relieve symptoms) and so on. Other treatments include chemotherapy, targeted drug therapy, immunotherapy, radiation therapy and so on. As for how to choose treatment for a specific patient, this should be determined comprehensively according to the type of pathology, genetic testing, staging, patient’s physical condition, etc.

The general principle is comprehensive treatment, standardized treatment, and individualized treatment, with special emphasis on multidisciplinary Comprehensive diagnosis and treatment (MDT).
