Cancer is a terrible disease with high morbidity and mortality, which makes people talk about cancer discoloration. However, in daily life, many people equate tumors with cancer, thinking that if they grow tumors, they will have cancer; some people think that malignant tumors are cancers.
So what is a tumor? This is a complex and simple issue. Since there are many varieties of tumors, books cannot be reduced to a complex sentence to describe what a tumor is. Normally, a tumor is an extra piece of "flesh" growing on the body.
The high incidence of tumors, and the cause of cancer, is a very obvious and highly consensual issue. However, we seem to be complicating it more and more. For example, age is regarded by many people as a risk factor for tumors, and even misinterpreted as the cause of tumors; and such as life habits, which are often used to explain tumors may be justified. Common are some of the formation factors, for example, dietary habits, eat barbecue every day some high-fat and high-calorie things, there is smoking and alcoholism, smoking is easy to damage the lungs and cause lung failure, drinking alcohol is easy to form liver and stomach are not comfortable, the other is some external factors, personal psychological factors These are also relatively rare elements.
Tumors are secondarily divided into two categories, one is the so-called benign tumor, and the other is the malignant tumor that "talks about cancer discoloration". Since the true cause of the onset of tumors in humans has not yet been found, it is difficult to distinguish between benign tumors and malignant tumors by definition. Benign can turn into malignancy, malignancy loses ineffective control and does not form a threat to the body, in reality, it is like a benign tumor. In 1953, human beings discovered the double helix structure of DNA, and finally learned through gene sequencing that tumors are cells in some tissues that are genetically regulated by their growth normally, causing their clonal abnormal hyperplasia and forming a reborn tissue, which gradually grows up to constitute a tumor.
Doctors call this extra piece of "meat" tumors, which are not all cancers, and medical scientists divide them into different types of names according to the tissues in which abnormal hyperplasias are located. In the past and even now, doctors have preliminarily determined the benign and malignant nature of tumors by examining the shape, softness and quantity of tumors with the naked eye. The most accurate diagnosis of benign and malignant tumors is histopathological biopsy introspection.
In fact, this kind of histopathological slice reflection still does not break the boundary of naked eye inspection, and there are many objective and human elements affecting the diagnosis of tumors and their properties. The cancer that everyone "talks about cancer discoloration" is an abnormal hyperplasia of epithelial tissue. Abnormal tissue hyperplasia derived from neuroepithelial cells is called glioma, abnormal tissue hyperplasia derived from mesoderm is sarcoma, and abnormal tissue hyperplasia derived from bone tissue is called osteosarcoma. There are also many tumors with various names, all of which are malignant tumors. Therefore, cancer is not the only malignancy. How evil is a malignant tumor? There is no answer to this score. Because, tumor cells are changing at any time.
The oncological disease of the human body is a disease caused by its own genes, not a disease caused by foreign bacteria and viruses invading the body. When gene signals regulate the orderly renewal of tissue cells, if there is a garbled code, tissue hyperplasia may form and tumors will occur. Doctors apply the atypage of tumor tissue cells to distinguish the level of malignancy, which is a manifestation of the abnormal differentiation of tumors in shape. The atyprae is small, the level of elucidation differentiation is high, the attenuation is large, and the level of elucidation is low. The difference between the size of this atypancy is to diagnose the tumor and determine the secondary histological basis for the benign and malignant tumors, that is, we usually say high differentiation, medium differentiation, low differentiation, etc. The lower the differentiation, the higher the level of tumor malignancy.
What is the complex boiling down to a tumor? Tumors are abnormal tissue hyperplasia, and tumors that only stay in part that do not run around, that is, controllable abnormal tissue hyperplasia are benign. Beautiful-looking scurrying around, uncontrollable abnormal tissue proliferation is malignant.
