hemorrhoids zinc oxide,Differentiation of hemorrhoids and rectal cancer

    Due to factors such as environmental pollution and food safety, the incidence of colorectal cancer has risen to the fourth place among malignant tumors. It is more than 40-50 years old. The median age group is about 45. People under 40 account for 1/of all cases. About 3, about 10% are under 30 years old. The high incidence of colorectal cancer in high-incidence countries is 60 to 70 years old, with about 6% of those under 30 years old. The age at which colorectal cancer occurs in China is 10 to 15 years earlier than abroad, and 11% to 13% are under 30 years old. This is a major feature of colorectal cancer in China. In 2000, 700,000 people were newly diagnosed with colorectal cancer and 500,000 died. In 2003, the incidence of large intestine ranked second in Shanghai, reaching 13.81% of malignant tumors. Therefore, early detection and early treatment of colorectal cancer are particularly important to improve the survival rate of patients. 70% of colorectal cancers occur in the rectum, and 80% of colorectal cancers occur in the lower rectum, which is a position that can be touched by a finger examination. This is a favorable condition for early detection of rectal cancer. The early symptom of rectal cancer is blood in the stool, so how to distinguish blood in the stool from hemorrhoids? There are two types of patients. One is panic and blindly seek medical treatment at the sight of blood in the stool; the other is carelessness and delays in medical treatment. Neither is desirable. For patients with blood in the stool, they can judge on their own and have a preliminary understanding of the nature of the disease. Generally, the stool is bloody red, without mucus, and those without other accompanying symptoms can basically consider hemorrhoids in the stool. The stool is bloody purple and dark, and the mucus is accompanied by anorectal swelling, stool deformation, weight loss, etc. Rectal tumors should be tested first. However, early tumors may only have dark purple blood or mucus in the stool. At this time, you should go to the hospital as soon as possible to find out the nature of blood in the stool and the disease.
