Symptoms of left colon cancer

summary

My stomach has been bad for some years, and I haven't paid much attention to it. Recently, the disease is quite serious. It's like appendicitis. But my appendix was removed a few years ago. I'm even more worried. I asked several people, and they all said it might be right colon cancer. Now let's talk about the symptoms of left colon cancer.

Symptoms of left colon cancer

First: digestive tract symptoms: abdominal distension, discomfort or dyspepsia like symptoms. Among them, the right half of colon cancer, mostly abdominal pain, discomfort or dull pain. At the beginning, it can be intermittent, and then it becomes persistent. It is often located in the right lower abdomen, which is very similar to the attack of chronic appendicitis. However, in the left colon cancer, the obstruction can be sudden, with abdominal colic, abdominal distension, hyperactivity, constipation and exhaust obstruction, or chronic obstruction symptoms, such as abdominal distension, paroxysmal abdominal pain, hyperactivity of bowel sounds, constipation, fecal blood and mucus.

Second: the change of defecation habits: the right half of colon cancer is characterized by early thin feces, pus and blood, and increased defecation frequency. When the cancer continues to grow, which affects the passage of feces, there will also be alternate diarrhea and constipation; while the left half of colon cancer is characterized by difficult defecation, which will continue to aggravate with the development of the disease. In addition, if the location of the cancer is low, there may be a feeling of poor defecation and urgency.

Third: the lumen of the left colon is thin, and the feces become dry and hard due to water absorption. Most of the left colon cancer is infiltrative type, often causing annular stenosis, so the main clinical manifestations are acute and chronic intestinal obstruction. Due to its small size, less ulceration and bleeding, and no toxin absorption, anemia, emaciation, cachexia and other phenomena are rare, and it is not easy to touch the mass.
