hemorrhoids symptoms,Symptoms and diagnosis of rectal cancer

    Symptoms and diagnosis of rectal cancer

    Rectal cancer includes cancer from the dentate line to the junction of the sigmoid colorectal, which accounts for about 60% of colorectal cancer. It is more common in the ampulla of the rectum, and about 2/3 is below the peritoneal reflex plane. The incidence is higher in the elderly, mostly over 60 years old. In recent years, it has occurred in young people from time to time. The youngest case I have seen is 15 years old. Patients younger than 30 years old account for 1-4%, and there are more men. The general symptoms of rectal cancer appear earlier, often tenes and poor bowel movements, and can also cause obstruction or changes in bowel habits. More than 90% of patients see blood as the first symptom, which is easy to be misdiagnosed as hemorrhoids bleeding and delay treatment, such as Cancer tissue invades the bladder and vagina, etc., and may cause frequent urination, urgency, hematuria, and even vesicovaginal fistula. Rectovaginal fistula related symptoms. Infringement of the sacral plexus can cause perianal and sacral pain.
