Second, patients with advanced cancer have symptoms such as abdominal pain, bloody stool, loose stool and diarrhea.
1. When rectal cancer grows to a certain extent, bloody stool symptoms may appear. A small amount of bleeding is not easy to find with naked eyes, but a large number of red blood cells can be found by stool microscopy, so-called fecal occult blood test is positive. When there is a lot of bleeding, there may be blood in the stool, and the color of blood is bright red or dark red. When the surface of cancer festers, ulcers are formed, and tumor tissue is necrotic and infected, purulent blood and mucus bloody stool may appear.
2. Patients may have different degrees of discomfort, anal prolapse, and sometimes diarrhea.
3. When rectal tumor leads to intestinal stenosis, there may be different degrees of intestinal obstruction symptoms (abdominal pain, abdominal distension and difficulty in defecation), abdominal pain and bowel sounds before defecation, and the symptoms are relieved after defecation. Stools can be thin and grooved.
4. Frequent urination, urgency, dysuria and dysuria may occur when the tumor invades the bladder and urethra; When the tumor invades the vagina, rectovaginal fistula can occur and fecal fluid can flow out of the vagina. When the tumor invades the sacrum and nerves, severe pain in the sacrococcygeal region and perineum may occur. When the tumor invades and compresses the ureter, it can cause pain in the waist; Tumors can also compress external iliac vessels, causing edema of lower limbs. All the above symptoms suggest that the tumor is in a relatively advanced stage.
5. When the tumor is distant metastasis (liver, lung, etc. ), symptoms may appear in the corresponding organs. For example, dry cough and chest pain may occur when it is transferred to the lungs.
6. Patients may have different degrees of fatigue, weight loss and other symptoms.
After understanding the early symptoms of rectal cancer, patients should always observe their own signs, seize the golden age of early treatment, and follow the law of cancer treatment, so that the disease can be effectively controlled and alleviated, and life safety can be guaranteed.
