There are more than 100 million cells on the body. The growth of cells and apoptosis are controlled by genes. The cells divide and grow and apoptosis according to certain rules, thereby completing a metabolism. However, some cells have escaped from genetic control and have abnormal differentiation or excessive proliferation, thereby inducing tumors. The harm of tumors is self-evident. They not only grow fast, but also easily transfer to surrounding tissues and organs, eventually destroying the body.
How does tumors destroy the body?
, compress
Because the tumor grows rapidly, when it grows to a certain extent, it can compress surrounding blood vessels, organs, nerves, etc., destroy its structure, and slowly lose its function. If it is a gastrointestinal tumor, it can affect the function of the digestive tract and induce intestinal obstruction; if it is pancreatic head cancer , as the tumor grows, it can compress the duodenal papilla, block the opening of the pancreatic bile duct, and induce obstructive jaundice , causing serious damage to liver function and eventually facing death.
Whether the brain tumor is primary or secondary, it will compress the heartbeat center and respiratory center , causing respiratory and cardiac arrest ; if it is pressed against the visual center, it will blind; generally, piles of cancer cells will fall off, block important blood vessels, and ultimately threaten life.
, bleeding
Malignant tumors continue to invade surrounding tissues and organs, causing blood vessel rupture and bleeding. For example, intestinal cancer can cause blood stool , lung cancer can cause hemoptysis, liver cancer can cause esophageal rupture and bleeding in the gastric fundus, gastric cancer and esophageal cancer can cause hemogloss, etc., and anemia caused by persistent bleeding, which can lead to circulatory failure in severe cases.
cancer cells gradually destroy large blood vessels. Take central lung cancer as an example. Lung cancer cells can invade the surrounding large blood vessels, causing large blood vessels to rupture, causing heavy bleeding in the body's organs, and threaten life without timely rescue.
3. Low immunity
Cancer cells can release a pararegulatory factor, which will inhibit the normal operation of the immune system and reduce resistance and immunity. In addition, the patient's long-term radiotherapy and chemotherapy and malnutrition reduces resistance and increases the risk of infection.
4. Cause nutritional deficiency
Cancer cells grow can increase physical discomfort. Patients often reduce their appetite due to nausea and vomiting, general fatigue, poor breathing, etc., resulting in a decrease in nutritional intake. The tumor is locally vascular disordered, and some tumors do not get enough blood and oxygen and supply.
In order to promote tumor growth, it will convert aerobic metabolism into aerobic to digest it, reducing the utilization rate of energy and destroying nutrients in the body. During the growth of cancer cells, nutrients in the body will be consumed quickly, which will cause energy deficiency over time.
Generally, after cancer develops to the middle and late stages, patients will experience malignant fluid , which is mainly manifested as anemia, general fatigue, body weight loss, and organ failure. It will also lead to various metabolic disorders and cause malnutrition.
Message from the doctors
Have you understood how tumors defeat the body step by step? Modern medicine still cannot overcome cancer. The best way is to prevent it. Stay away from all carcinogenic factors, including smoking and drinking, exposure to toxic and harmful substances, etc.; maintain a regular schedule and moderate exercise, and learn to release stress.
formulates appropriate cancer screening projects based on their own age, living habits, family cancer history and gender, such as low-dose spiral CT screening for lung cancer, gastroscopy screening for gastric cancer, colonoscopy screening for colorectal cancer, breast mammography or breast B-ultrasound screening for breast cancer , serum alpha-fetoprotein and liver color ultrasound screening for liver cancer, etc., to facilitate early detection and early treatment.
