What are the early symptoms of colorectal cancer?

The incidence of colorectal cancer is very high in life, so it is necessary for us to understand the early symptoms of colorectal cancer . Next, let's explore this knowledge from the following article.

1. Changes in bowel habits are one of the early symptoms of colorectal cancer. Unexplained changes in bowel habits, mainly increased bowel movements, rarely constipation, are mostly 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. Early symptoms of colorectal cancer may also include changes in stool properties. Stool changes from watery to 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. Patients with colorectal cancer may have a small amount of mucus sticking to their stool, which is a warning sign of rectal cancer.

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

The above are the main early symptoms of colorectal cancer. I believe that everyone can learn as much as possible about colorectal cancer. If you have other questions about colorectal cancer, you can contact our online experts to answer your questions.
