What are the early symptoms of colorectal cancer?

Cancer treatment experts say that colorectal cancer is a common tumor in my country, second only to lung cancer and stomach cancer in incidence. Malignant tumors that usually occur in the colon, rectum, and anal canal are collectively referred to as colorectal cancer. Timely detection of early colorectal cancer is of great significance to the treatment and prognosis of patients. Experts will introduce you to the early symptoms of colorectal cancer.

(1) The early symptoms of colorectal cancer are generally as follows:

① The stool contains blood or is black in color, but it cannot be explained by hemorrhoids.

② Changes in bowel habits, abnormal bowel movement frequency or mucus in stool, constipation, diarrhea, or alternation of the two for more than 3 weeks should be paid special attention.

③ Those with persistent or recurrent bloody stools, a feeling of incomplete defecation (still having the urge to defecate after defecation), and poor response to dysentery treatment.

④ The shape of the stool changes, becoming thinner, flatter or having grooves.

⑤ Anemia occurs, and occult blood is repeatedly or continuously found in stool examination.

⑥ Persistent lower abdominal discomfort, dull pain or bloating, abdominal mass (colon cancer is less malignant than gastric cancer and pancreatic cancer, and 20.1% of colon cancer patients with abdominal mass are still stage I cases), weight loss

⑦ Intestinal obstruction or intermittent abdominal cramps

The early symptoms of colorectal cancer are not obvious, and the symptoms occur intermittently and incoherently, so they are easily ignored or misdiagnosed as other diseases, thus delaying the best treatment time. More than 90% of patients with early colorectal cancer can be cured, while the survival rate of patients in the late stage is less than 5%. Therefore, mastering some early symptoms of colorectal cancer is very important for early detection and early treatment.

Cancer treatment experts say that the onset of colorectal cancer depends on the location of the tumor, its size, the extent of the lesion, and whether there are complications. The most important and early symptoms of colorectal cancer are changes in bowel habits, alternating diarrhea and constipation, increased bowel movements, or changes in the original regularity or dryness of the stool, all of which may be early symptoms of colorectal cancer.

According to tumor treatment experts, the principle of minimally invasive interventional treatment for colorectal cancer is to place a catheter under DSA monitoring into the blood vessels supplying the tumor, infuse chemotherapy drugs through the catheter to kill tumor cells, and then inject substances (embolic agents) that block the blood vessels supplying the tumor through the catheter, causing tumor cells to be ischemic and hypoxic, and die of starvation. Interventional treatment can greatly increase the cure rate, improve the quality of life of patients, and prolong the survival of patients, thereby achieving the principle of giving equal importance to treatment effect and quality of life.

Indications for interventional treatment: primary liver cancer, bronchial lung cancer, pancreatic cancer, kidney cancer, pelvic malignant tumors, head and neck tumors, middle and lower esophageal tumors, gastric cancer, colon cancer, rectal cancer, liver metastases and other patients who are not suitable for surgery and malignant tumors of the limbs that cannot be surgically removed or are difficult to remove surgically.
