What are the specific early symptoms of colorectal cancer?

The onset of colorectal cancer is very slow. As a patient, you must first understand the early symptoms of colorectal cancer . What are the main early symptoms of colorectal cancer? Let's take a look at the early symptoms of colorectal cancer.

1. Unexplained changes in bowel habits. The early symptoms of colorectal cancer are mainly increased frequency of bowel movements, and very rarely constipation. Most of them are cancers in the sigmoid colon and rectum (left-sided colon cancer). Because they are relatively close to the anus, frequent bowel movements are an important signal of left-sided colon cancer.

2. Changes in stool properties. Stool changes from sometimes watery to sometimes with a small amount of mucus to blood or occult blood, which is a sign of the development of colon cancer from early to late stages. The presence of a small amount of mucus in the stool is especially a warning sign of rectal cancer.

3. Abdominal distension and pain. The early symptoms of colorectal cancer are signals of the ascending colon and transverse colon (right colon cancer). Because these parts are far from the anus and do not stimulate the anus much, there is little change in the frequency of bowel movements. The early symptoms of colorectal cancer are mainly abdominal distension and occasional dull pain. If the pain is obvious and a lump is found, it is no longer in the early stage. Colorectal cancer includes colon cancer, rectal cancer and anal cancer. Colorectal cancer with a diameter of less than 2 cm and no lymph node metastasis is considered early colorectal cancer.
