Early symptoms of gastrointestinal cancer?

summary

When it comes to cancer, we will think of "cancer" and "death". In the face of "advanced cancer", the current medicine can only maintain the life of patients through chemotherapy, but can not completely cure them. The incidence rate of gastrointestinal tumors is the highest among all kinds of cancers. Among them, gastric cancer is a common disease worldwide. The incidence rate of gastric cancer is fourth in the whole body tumor, and the mortality rate is second. Early symptoms of gastrointestinal cancer? Let's talk about it.

Early symptoms of gastrointestinal cancer?

With regard to gastric cancer, we should first understand the canceration of any part of the stomach, which is called gastric cancer in medicine, because there are many layers in the gastric wall, including mucosa, submucosa, basal layer, serosa layer, and so on. Just like skin, it is also divided into epidermis, dermis, and subcutaneous tissue.

Gastric cancer generally originates from the mucosa, submucosa and basal layer. The location of cancer determines the stage of cancer. Early gastric cancer refers to the invasion of cancer cells into the mucosa and submucosa, which can be cured by mucosal resection. The 5-year survival rate is as high as 90%; Once it reaches the base or serosa layer, it belongs to the middle and late stage, and the cure rate will drop by half; When the cancer cells break through the gastric wall and metastasize to the liver, they are in the advanced stage, and the five-year survival rate is less than 10%.

Colon cancer is another kind of common gastrointestinal tumor. The age of onset is mostly after 40 years old, and the sex ratio is more obvious. The ratio of male to female is 2:1. The common site of colon cancer is at the junction of rectum, rectum and sigmoid colon, and the tumor occurs on the mucosa of the inner wall of colon. Compared with other cancers, the time from occurrence to canceration of colon cancer is longer, which is not only conducive to medical research, At the same time, it also increases the opportunity of early detection and early treatment of patients. Nowadays, the effective method of medical treatment for colon cancer is resection.
