What are the early signs of colorectal cancer?

People with colorectal cancer must detect and treat it early to avoid the disease from worsening and posing a threat to their life safety. To this end, here are some early signs of colorectal cancer so that the disease can be detected and treated early.

Digital rectal examination is the simplest and most important early diagnosis method for this disease. The main symptoms of unexplained intestinal dysfunction are changes in bowel habits (increased frequency) and changes in nature (or mucus, or occasionally a small amount of blood), which are early signs of colorectal tumors.

In addition, typical early signs of colorectal cancer are: frequent urge to defecate, gradually developing into tenesmus, deformed stools (mostly flat or thin), stools developing from a small amount of mucus to a small amount of blood, and abdominal pain and cachexia in the late stage.

The above is an introduction to the early signs of colorectal tumors. Experts remind that colon cancer may also have extra-colonic signs, such as carcinoid syndrome: skin flushing, diarrhea, asthma, cyanosis, difficulty breathing and other symptoms.
