Diarrhea is a common symptom of rectal cancer. For symptomatic treatment, we can take medications such as montmorillonite powder or loperamide to alleviate diarrhea, and use probiotics like Bifidobacterium triple or quadruple live bacteria to regulate intestinal flora. However, these treatments only alleviate symptoms rather than cure the underlying disease. The key is to control the rectal cancer itself. Treating the tumor is the fundamental solution. Only when the tumor is under control will the patient's diarrhea symptoms be relieved. Otherwise, even if the symptoms are alleviated by antidiarrheal drugs, if the tumor is not controlled, symptoms including diarrhea, rectal bleeding, and abdominal pain will recur and may even worsen.

What are the symptoms and early signs of rectal cancer?

In the early stages of rectal cancer, there are no obvious symptoms. Only when the condition progresses to a certain extent do some clinical symptoms appear. The first is a change in bowel habits or the nature of the stool. The second possible symptom is abdominal pain. The third possible outcome is intestinal obstruction. The fourth symptom occurs when the tumor develops to a certain extent, and lumps can be felt in the abdomen. The fifth point includes possible symptoms of systemic poisoning such as anemia, weight loss, fever, and weakness. The sixth point is that in the advanced stages of rectal cancer, some metastatic lesions may appear, such as extensive pelvic metastasis and infiltration, leading to pain in the sacral area and sciatic neuralgia; if areas like the vaginal, rectal mucosa, or bladder mucosa are involved, there may be vaginal bleeding or blood in the urine, resulting in conditions like rectovaginal or rectovesical fistulas.

Stage IV rectal cancer

In the staging of rectal cancer, we generally use the TNM staging system clinically. "T" refers to the primary tumor, "N" indicates whether there is lymph node metastasis, and staging is based on the status of the lymph nodes. "M" indicates whether there is distant metastasis. Stage IV refers to any stage of "T" and any stage of "N", as long as there is distant metastasis, such as rectal cancer metastasizing to the liver, lungs, or bones. When these distant organ metastases occur, the staging is M1, any "T", any "N", M1. This scenario is stage IV, indicating the presence of distant organ metastasis and represents advanced stage rectal cancer patients.

Early symptoms of rectal cancer

The early symptoms of rectal cancer generally include the following aspects: many patients experience changes in their bowel habits, such as prolonged diarrhea, prolonged constipation, or alternating occurrences of diarrhea and constipation. Some patients also experience changes in the characteristics of their stools, with stools becoming thinner and more watery due to increased bowel movements. Additionally, some patients may excrete stools mixed with mucus, pus, and blood, or stools that contain blood, and may experience a feeling of urgency followed by a sensation of incomplete evacuation. Some patients also feel itching or a dull pain in the anal area. Moreover, the early symptoms of rectal cancer are not very prominent, and many patients can easily confuse them with benign rectal diseases such as hemorrhoids and anal fissures. This confusion leads many patients not to seek medical attention, and by the time symptoms like significant pain and lumps appear, the disease is typically in its intermediate or advanced stages.
