Q: Can hemorrhoids become cancerous?
Answer: Can hemorrhoids become cancerous? This is a particular concern and worry for patients with hemorrhoids. Because blood in the stool is well known as a warning sign of rectal cancer, many patients with hemorrhoids wonder if their hemorrhoids will turn into rectal cancer. This kind of thinking is understandable, but it lacks scientific basis. Hemorrhoids cancer has not been reported in domestic and foreign literature so far, and hemorrhoids are not included in the etiology of rectal cancer. It is common for some patients with hemorrhoids to have rectal cancer or colon cancer, but this is mostly caused by malignant changes in the intestine of the affected area, and has nothing to do with hemorrhoids.
There are indeed clinical reports that quite a few patients with rectal cancer have a history of hemorrhoids treatment or even surgery, which often leads to the association of many people with hemorrhoids developing into cancer. It has been clinically confirmed that there is no necessary connection between the two.
If a middle-aged person has repeated blood in the stool and cannot be explained by hemorrhoids after the examination, he must be alert to the possibility of rectal cancer, but this does not support the inference that hemorrhoids become cancerous
In short, there is no direct evidence for the relationship between hemorrhoids and rectal cancer. Clinically, many patients with blood in the stool have been found, some even young people, who came to see hemorrhoids, but after a doctor's examination, they were found to be rectal cancer. Therefore, all patients with recurrent blood in the stool, especially those with changes in bowel habits, increased stool frequency, difficulty in defecation, and peculiar smelly stools, must seek medical attention as soon as possible to confirm the diagnosis in time to avoid delay in diagnosis and treatment.
