CHARACTERISTICS OF MALIGNANT TUMORS

Why do malignant tumors in cancer endanger life? When the malignant tumor expands, it presses against surrounding cells and tissues, showing two dangerous characteristics: its invasive nature, or its tendency to invade outlying tissues, and its metastatic nature, or its tendency to travel to other parts of the body through blood or lymphatic channels and grow there.

It is commonly recognized that damaged DNA causes these malignant tumors which lose control over the formation of cells through cell division. The cells grow uncontrollably by unlimited mitosis, and when they expand into adjacent tissues, they cause damage. What is even more worrisome is that the human body is filled with blood vessels and lymphatic, which may carry the abnormal cells from one tissue area to another, where they will set up new foci of abnormal growth. These are the special features of cancer invasion and metastasis.
