What are the symptoms and diagnosis of rectal cancer?

Rectal cancer is a malignant tumor that often occurs in the gastrointestinal tract and causes great harm to the human body. Knowing the symptoms of rectal cancer is important for timely detection and treatment of gastrointestinal cancer. What are the symptoms of rectal cancer? Let's ask experts to introduce the symptoms of rectal cancer to you.

The main symptoms of rectal cancer are:

In the early stage of diagnosis, the symptoms of rectal cancer are not very obvious, or there is only blood in the stool, which is similar to the symptoms of ulcers and is often ignored. Some patients may have a slightly increased frequency of bowel movements and loose stools. In the early stage of rectal cancer diagnosis, small nodules or small ulcers can be touched, which are not hard in texture and can move with the mucosa and have good mobility.

In the middle stage, the symptoms of rectal cancer gradually become obvious. The patient has obvious changes in bowel habits, with up to ten or more bowel movements a day, mostly loose stools or mucus stools, and sometimes bloody or thick bloody stools. There is a clear sense of urgency, and some patients may have fresh blood in their stools. There is dull pain or heaviness in the abdomen before and after each bowel movement.

In late-stage patients, the symptoms of colorectal cancer above the rectum are significantly aggravated, accompanied by anemia, weight loss, and obvious pain in the anus. Some patients may experience symptoms of low intestinal obstruction such as abdominal distension, abdominal pain, nausea, and vomiting. Some may also develop ascites, jaundice, frequent urination, and dysuria. Patients in the very late stage develop cachexia.

In the middle stage, digital examination can feel a cauliflower-like mass with raised edges and ulcers in the middle. It is brittle and easy to bleed, with a certain degree of mobility. In the late stage, digital examination can feel a hard, stone-like mass that often surrounds the rectum. The local intestinal tract is stiff and narrow, the mass is brittle and easy to bleed, and it is fixed to the pelvis and cannot move.

The above is an introduction to the symptoms of rectal cancer. I hope you can understand the symptoms of rectal cancer in each stage and receive timely treatment to avoid life-threatening situations in the late stages.
