Can colorectal cancer cause low back pain?

Colorectal cancer is a malignant tumor of the intestine that affects the human digestive system and brings a serious burden to people. In order to effectively treat and control it, we must understand its symptoms so that we can choose targeted treatment.

In the early stage of colorectal cancer, there are no symptoms or the symptoms are not obvious, only discomfort, indigestion, occult blood in stool, etc. As the cancer develops, symptoms gradually appear, manifested as changes in bowel habits, abdominal pain, blood in stool, abdominal mass, intestinal obstruction, etc., with or without systemic symptoms such as anemia, fever and weight loss. Tumor metastasis and infiltration can cause changes in the affected organs. Colorectal cancer shows different clinical symptoms and signs due to different locations of occurrence.

1. Right colon cancer

The main clinical symptoms of right colon cancer are loss of appetite, nausea, vomiting, anemia, fatigue, and abdominal pain. Right colon cancer causes iron deficiency anemia, which manifests as fatigue, weakness, shortness of breath, and other symptoms. Because the right colon has a wide intestinal cavity, abdominal symptoms will not appear until the tumor grows to a certain size. This is also one of the main reasons why the tumor is diagnosed at a late stage.

2. Left colon cancer

The left colon cavity is narrower than the right colon cavity, and left colon cancer is more likely to cause complete or partial intestinal obstruction. Intestinal obstruction leads to changes in bowel habits, constipation, blood in the stool, diarrhea, abdominal pain, abdominal cramps, bloating, etc. Stool with fresh blood indicates that the tumor is located at the end of the left colon or rectum. The disease is often diagnosed earlier than right colon cancer.

3. Rectal cancer

The main clinical symptoms of rectal cancer are blood in the stool, changes in bowel habits, and obstruction. Patients with lower tumors and harder feces are easily rubbed by the feces to cause bleeding, which is mostly bright red or dark red, not mixed with formed feces or attached to the surface of the fecal column, and is misdiagnosed as "hemorrhoidal" bleeding. Secondary infection of lesion stimulation and tumor ulcers constantly causes defecation reflexes, which are easily misdiagnosed as "enteritis" or "bacillary dysentery." Those with ring-shaped tumor growth will cause narrowing of the intestinal cavity, which is manifested as deformation and thinning of the fecal column in the early stage and incomplete obstruction in the late stage.

Through the above treatment, we know some symptoms of colorectal cancer. It can be said that the symptoms are still very obvious. I hope everyone will pay attention to it in life. If the above adverse symptoms occur, go to the hospital for examination and treatment in time to avoid delaying the best time to treat the disease.
