Most of the organs in human body can get cancer, we often hear about stomach cancer, liver cancer, lung cancer, kidney cancer, but we seldom hear about heart cancer, why? Next, I will introduce the reasons why the heart does not get cancer from the perspective of Chinese medicine and Western medicine respectively in detail. From the perspective of Chinese medicine, the heart does not get cancer. The heart is the ruler of the five viscera and six bowels and cannot be harmed by evil. If the heart is compared to a monarch, the pericardium is like a palace city. The pericardium is the envelope that wraps around the outside of the heart, at the periphery of the heart, and has the function of protecting the heart. Problems with the heart will first be reflected in the pericardium. When the evil Qi invades, is injured or when the condition is critical, the pericardium is the first to bear the burden in order to avoid or reduce the damage to the heart. Therefore, the pericardium has the function of “receiving evil on behalf of the heart”. Chinese medicine has a “life-saving pericardial meridian” said. Manifestations of evil in the pericardium The middle punch of the pericardium meridian is located on the middle finger. Numbness in the middle finger may be a problem of the pericardium. Heart disease is first manifested in the pericardium, and the disease of the pericardium meridian is called “tantalizing movement in the heart”, which means panic or a feeling that the heart is beating outward. Sometimes the pericardium is disturbed by wind and dampness, but the problem does not appear immediately. For example, if wind-damp-heat invades the pericardium, it often stays dormant for 20 years before developing rheumatic heart disease; if cold evil invades the pericardium, it blocks the blood pathway and becomes angina pectoris; if water-damp evil invades, it becomes pericardial effusion. A distinction needs to be made: heart disease is not a result of evil, but rather a damage to the heart’s own function. If the heart is subjected to evil, the disease that appears is a disease of the mind, not a heart attack. 2. From the perspective of western medicine, the reason why heart should not have cancer 1. It is related to the tissue structure of the heart Cancer comes from epithelial tissue chemistry, and anywhere there is epithelial tissue, there is the possibility of cancer. Epithelial tissues cover the surface of human body, also cover the inner surface of digestive tract, respiratory tract, urinary tract and reproductive tract, or constitute the substantial components of liver, kidney, breast, prostate and other organs. Cancer is a malignant tumor that occurs from epithelial tissue. There is no epithelial tissue in the heart, and naturally, primary cancer does not occur. 2.Related to the unique anatomical position of the heart The heart and blood vessels constitute a closed blood circulation system, which makes it less susceptible to direct attack by external harmful substances. Many carcinogenic substances that people face in life may cause different degrees of damage to organs such as nasopharynx, oral cavity, esophagus, gastrointestinal tract, lungs and skin, which may lead to malignant lesions. Compared with these organs that are exposed to harmful substances every day, the heart, which is deep in the heart of the body, is less likely to be directly attacked by these carcinogens. The harmful substances that enter the blood stream are also continuously purified as they pass through the liver, spleen and kidneys. After such a process, it is difficult for some harmful substances in the blood to cause adverse effects on the heart. 3.Related to the function of the heart The heart is the pumping station of human blood circulation. The blood flowing through the heart never stops in a person’s life. Even the malignant tumor cells in metastasis are not easy to stay in the heart. In fact, most of the metastatic tumors in the heart are local invasion from primary or secondary malignant tumors in the lung or mediastinum.
