The relationship between rectal cancer and melena, whether rectal cancer will cause constipation

Don't worry too much, go to a professional municipal hospital for relevant examinations, if you are not at ease, you can have a blood test and a full colonoscopy.

Just like the relationship between Liang Shanbo and JulietI can't tell.

Black represents toxins in the body, like just a few days after recovering from illness, constipation will also, it is generally a warning signal from the body, it will not be cancer, don't think about it so seriously, eat something light and it's fine.

Recently, a patient reported that he had frequent constipation for more than a year. Sometimes once every two or three days, sometimes once every four or five days, using diet therapy for a long time, or constipation, and then I heard that eating honey can be relieved, but as a result, it was used for a period of time, but it was still constipated, which I thought was a common disease of the elderly. It wasn't until I went to the hospital for a check-up because of abdominal pain and vomiting that I found out that I had rectal cancer.

Expert answer: In recent years, the incidence of colorectal cancer (including colon cancer and rectal cancer) has been increasing around the world. Early detection and early medical treatment are the key to colorectal cancer. However, due to the lack of typical clinical manifestations of colorectal cancer, patients often waste a lot of valuable time from the discovery of symptoms to the time they seek medical attention, and the best time is lost.

Early symptoms of colorectal cancer include:

1. Change in bowel habits (increased frequency of stool or diarrhea, constipation), obviously you meet this situation.

2. The stool is bloody (easy to be confused with hemorrhoids) or black.

3. Thinning of stools.

4. Tenesmus (there is still a desire to defecate after defecation).

5. Intermittent abdominal cramps.

Once these symptoms are noticed, patients should go to the hospital as soon as possible.

Colorectal cancer is mainly treated with a combination of surgery and chemotherapy. Although all the macroscopic tumors can be removed during surgery, it is still common for patients with rectal cancer who have undergone sexual surgery, especially those whose tumors involve the serosa or metastasize of regional lymph nodes.

If the patient has pre-existing hepatic or extrahepatic metastases, the postoperative** rate is higher. In order to prevent the local tumor from local**, in addition to radiotherapy, local chemotherapy can also be used. The most common metastases of colorectal cancer are the liver and abdominal cavity, and these metastases often develop from small metastases that are pre-existing at the time of initial diagnosis.

Systemic chemotherapy can also be used to prevent distant metastases, with systemic chemotherapy given before and after surgery, and local chemotherapy given before, during, or after surgery.

In fact, the patient has long-term constipation.

If it is not treated in time, it will also cause rectal cancer.

The two influence each other. Once constipation occurs, patients should be timely and accurate, and must not miss the time, resulting in irreversible serious consequences.
