What are the symptoms of rectal cancer

What are the symptoms of rectal cancer?

Early stage rectal cancer usually has no obvious symptoms, but late stage rectal cancer may have:

1. Rectal irritation symptoms, such as changes in bowel habits, anal prolapse, heaviness, and incomplete defecation;

2. Symptoms of intestinal stenosis, loose stools, partial intestinal obstruction, and possible incomplete intestinal obstruction;

3. Tumor damage can also cause some infectious diseases, such as bloody stools and mucus, or even pus and bloody stools;

4. Tumors invade the prostate and bladder, which may cause frequent and urgent urination;

5. After the tumor invades the presacral nerve, severe pain may occur in the sacrum and coccyx;

6. Ascites, liver swelling, jaundice, anemia, weight loss, edema, etc. May occur in the late stage of liver metastasis.

Rectal cancer is a common surgical disease that seriously threatens people's health. Early stage rectal cancer has no symptoms, or may only have some atypical digestive tract symptoms, such as nausea, vomiting, abdominal distension, etc.

As the tumor continues to expand and invade peripheral blood vessels, symptoms such as black stools may occur, or abdominal pain, constipation, bloody stools, and mucus in the intestinal wall may appear.

When the tumor continues to grow and blocks the intestinal cavity, symptoms of intestinal obstruction may occur. When the tumor continues to expand and invade surrounding organs, systemic symptoms such as hematuria, weight loss, and anemia may occur after acute exacerbation. Due to the hidden location of rectal cancer, it is difficult to detect it early, so a colonoscopy can be performed as soon as possible.
