Speaking of it, the heart is really special, and you can say "no" to cancer. The reason why the heart has such "magical ability" is mainly because of its structure.
The formation of cancer is mainly due to the epithelial tissue of organs. It can be said that there is not necessarily cancer where there is epithelial tissue, and there must be no cancer where there is no epithelial tissue, but the heart is still such a place without epithelial tissue. Epithelial tissue of human body covers the surface of human body, and also exists inside and outside digestive tract, respiratory tract and urogenital tract. In addition, human organs are also composed of epithelial tissues, so these organs have the opportunity to get cancer. Only the heart has no epithelial tissues, so the heart naturally does not get cancer.
Moreover, the unique anatomical position is also one of the capitals of the "willfulness" of the heart. The human heart and blood vessels together form a closed blood circulation system, so harmful substances from outside can't directly damage it. Other carcinogens can enter the body through human mouth, nasopharynx, stomach, lungs and other parts, causing damage to various organs in the body, and then causing malignant lesions of organs. Compared with these organs that are invaded by harmful substances from outside every day, the environment of the heart is much better and there can be no pathological changes.
Human blood must be continuously purified by liver, kidney and spleen, and finally it can reach human heart. Even if there are some harmful substances in the blood after multi-layer purification, these harmful substances can not cause damage to the heart.
In addition, the function of the heart also determines that it will not get cancer. The human heart is beating all the time, so even if there are malignant cells, these cells will transfer to other parts of the human body with the beating heart.
