    80% of rectal cancers have been misdiagnosed as hemorrhoids

    Xiao Wang is a handsome young man who just turned 30 this year.


    Under the repeated persuasion of the anorectal doctor, I reluctantly came to our endoscopy center for colonoscopy


    Before the examination, Xiao Wang didn't care, and said swearingly, "I am a hemorrhoid.


    As a result, the mirror just entered 10 cm, and I saw the following:

    At that time, a poorly differentiated invasive carcinoma was considered, and the pathological result came out: "(10 cm from the rectum) small cell malignant tumor, tending to be poorly differentiated carcinoma, further classification by immunohistochemistry

    Not to mention, how Xiao Wang's wife faced this result, and how embarrassing the three-year-old son is.


    Hemorrhoids and rectal cancer can both cause blood in the stool

    Hemorrhoids are venous masses formed by varicose veins in the lower rectum, anal canal and anal border.


    Hemorrhoids are venous masses formed by varicose veins in the lower rectum, anal canal and anal border.


    Therefore, its bleeding is mainly caused by various reasons (such as sedentary, weakened immunity, long-term oral anticoagulants, drinking, spicy stimulation, etc.


    Rectal cancer is a malignant tumor and is the "abnormal tissue" of the human body


    Therefore, the source of bleeding is mostly caused by cancer infiltrating the rectal mucosa and causing the surface ulceration or the ulceration of the cancer itself
