How to detect the early stage of rectal cancer

summary

My father suffered from rectal cancer without surgery. He is 70 years old and has cerebral infarction for 17 years. Now he takes traditional Chinese medicine and occasionally has bloody stool. After medication, the symptoms have improved significantly. I'm so happy. Now let me talk to you about how to find the early stage of rectal cancer.

How to detect the early stage of rectal cancer

First: ultrasonography, intrarectal ultrasonography is a new diagnostic method to detect the invasion of rectal cancer and the degree of invasion of rectal wall. It has been used in clinic since 1983.

Second: magnetic resonance examination, some researchers said that for the invasion of rectal cancer, magnetic resonance examination (MRI) is more significant than CT. At the same time, compared with intracavitary ultrasound, the high cost of MRI is also an obstacle to its wide application.

Third: CT diagnosis, CT can not be used as a method of early diagnosis, but CT is of great significance to the staging of colon cancer, especially for the patients who can not be estimated to be operated directly, but may be resected after external radiotherapy or local intracavitary radiotherapy. CT is of great significance in the surgical evaluation of advanced rectal cancer and recurrent rectal cancer. It can directly observe the invasion of pelvic muscle (levator ani, obturator, caudal bone, piriform gluteus), bladder and prostate.

matters needing attention

High fat, high animal protein, refined carbohydrates and fiber diet, promote the development of rectal cancer. In addition, eating smoked, barbecued and fried food, drinking strong liquor frequently, and long-term less exercise, constipation, overweight and obesity increase the risk of rectal cancer. To be sure, cancer is eaten.
