Cancer itself is a malignant tumor caused by cell mutation and proliferation, but it is different from benign tumor. After cell canceration and formation of cancer, cancer cells will not be limited to a certain organ or tissue. They will gradually infiltrate around and transfer to other parts through the circulatory system, eventually causing multiple organ failure, complications and death.
in recent years, with the continuous development of medical technology, there are many types of early cancer. After scientific treatment, patients’ condition can be effectively controlled, and even reach the standard of clinical cure. For example, colon cancer is one of them!
However, colorectal cancer is similar to other types of cancer, which is occult in the early stage, and the patient does not even have any symptoms. Even after the occurrence of symptoms, such as stool changes, bloody stool and so on, patients often think that they have hemorrhoids, and then ignore the examination of the intestinal tract. Clinical have a lot of cancer patients in a long period of time before the diagnosis, think that is hemorrhoids in trouble!
hemorrhoids are clinically divided into different grades and types. Hemorrhoids do have hematochezia in the development stage. Usually in the process of defecation, there are bloody stool, bleeding and other manifestations, and even jet bloody stool in severe cases. But this kind of blood generally presents bright red, and is not mixed with the stool, the blood is basically floating on the surface of the stool, when the end of the stool, the hematochezia will stop, some patients will be accompanied by pain and itching;
and the hematochezia induced by colon cancer is completely different, with the continuous development of colon cancer, the cancer may have ulceration and bleeding. But because the amount of bleeding is relatively small, even if mixed in the stool, the patient is often difficult to detect, stool routine examination, can find fecal occult blood positive.
in some patients, due to the small amount of bleeding, the bleeding site is far away from the anus, the blood will decompose and oxidize in the intestinal tract, hemoglobin will combine with sulfide, and finally form black feces. And in a large amount of bleeding, infection, patients can appear mucoid, pus like bloody stool.
hemorrhoids and colorectal cancer may have pain, but the specific performance is not the same. Hemorrhoids caused by pain are generally concentrated in the perianal, and defecation is more obvious pain, pain after defecation gradually decline, the duration is not long, usually patients easily will not have perianal pain. In addition, affected by the increased secretion, patients may also have anal pruritus;
the pain of colorectal cancer is generally not around the anus, because the intestine is in the abdominal cavity, so the pain is mainly concentrated in the abdomen. Early cancer pain is not obvious, mainly mild dull pain, tingling, etc., but also does not highlight the specific parts of pain. When the cancer develops to a certain stage and causes pressure on the surrounding tissues and organs, the pain will gradually aggravate, showing persistent abdominal pain, which will not be alleviated with the arrival or end of stool.
Finally, I would like to remind you that both hemorrhoids and colorectal cancer need professional diagnosis and treatment. In the presence of hematochezia symptoms, regardless of whether it is colorectal cancer, should be the first time to see a doctor for examination. At present, the commonly used clinical examination methods are anal digital examination, colonoscopy, etc. once diagnosed with colorectal cancer, we should actively cooperate with doctors for treatment. 20
