The composition of each type of tumor is different.
Generally, benign tumors are composed of cells that have the tumor**.
Malignant tumors have atypic cells of the tumor**, as well as necrotic and degenerative cellular components.
-
There are necrotic blood and cells in it.

The essence of tumor is a new organism formed by the proliferation of local histiocytes under the action of various tumorigenic factors, because this new organism mostly presents a space-occupying lumpy protrusion, also known as vegetation. From the perspective of traditional Chinese medicine, the essence of tumors is insufficient heat and cold accumulation.
From a biological point of view, cell differentiation and apoptosis are related to cell executive functions and belong to "yang qi", while cell proliferation is related to the number of cells and body growth, which belongs to "yin formation", and abnormal development, uncontrolled proliferation, differentiation disorder and apoptosis inhibition are the basic biological characteristics of tumors and leukemia.

The essence of tumors is that cells will have metabolic changes that are different from normal cells, and tumor cells themselves can adapt to changes in the metabolic environment through the conversion between glycolysis and oxphosphorylation (oxphos).
In 2019, Cancer Cell published a new article in which researchers found that the use of metformin in a fasted state can significantly inhibit tumor growth, and proposed that the PP2A-GSK3-MCL-1 pathway may be a new target for tumors**.

The essence of tumor: What is the English name of tumor, tumor, which means tumor; Lump; Vegetations. Note that the last meaning, growths, means that they are superfluous.
Let's not analyze it from a biological point of view, what oncogenes, tumor suppressor genes, if you say that you are not in this major, you may not understand, let's be concise. Tumor is a group of cells that do not obey the command, unlimited reproduction, cells, more is what we call meat, tumor is actually an extra piece of meat on the body, this excess meat you remove it, it will still **. So why are so many people afraid of tumors, this mainly depends on where it grows, if it is on some important organs, it will be fatal, then it is cancer, it will kill people, for example, if it does not grow eyes in the esophagus, then this piece of fat will block the esophagus, people can not eat, and it will grow after removal, this is esophageal cancer, so people who get esophageal cancer generally die very miserably - starvation.
If it grows on non-vital parts such as legs or arms, then it is absolutely necessary for it to grow there, as long as it does not spread. Tumors are also divided into malignant and benign, malignant is diffuse, benign is non-proliferated. In short, the essence of a tumor is a superfluous group of cells that don't listen, or an extra piece of fat.

The essence is a new organism formed by the proliferation of local histiocytes under the action of various tumorigenic factors, because this new organism is mostly a space-occupying block-like protrusion, also known as vegetation. Dysplasia, uncontrolled proliferation, impaired differentiation, and apoptotic inhibition are tumors.
-
Nature of tumor: What is the English name of tumor, tumor, which means tumor; Quality; Vegetation. Note the last meaning, vegetation, which is superfluous.
I'm not going to analyze it from a biological point of view, what oncogenes, tumor suppressor genes, I may not understand if I am not professional, I will be concise. A tumor is a group of cells that do not listen to commands, multiplying indefinitely, the cells are more of what we call meat, and the tumor is actually how long a piece of meat is on the body.
-
I am a practitioner, and the essence of cancer is the result of bad habits, that is, there is a law of cause and effect in heaven and earth, and good habits result from bad habits. Don't be afraid of this disease, it's just a disease, and if you think that Amitabha Buddha can cure it, you can cure any strange disease with Buddhism, and the Dharma can achieve immortality and immortality, not to mention a small karmic disease.

There are tumor cells in each person's body, and once induced, these cells will grow, affect the function of organs, and eventually lead to the end of human life. And these cells will travel with the blood of the body, and will take root and grow in other places, which is called cancer metastasis.
-
Cells that grow out of control in the human body.
Just like people who have no one to supervise and manage, there will always be some people who want to do bad things, or even big bad things.
Tumor cells are cells that are out of control, grow out of control, deteriorate in nature, and endanger life.

Under the action of various carcinogenic factors, the cells of local tissues lose their normal regulation of their growth at the gene level, resulting in abnormal local cell proliferation, and the formation of new organisms is called tumors. Tumorigenesis is associated with: Tumoris is the result of monoclonal expansion of tumor cells; Environmental and genetic oncogenic factors can often lead to the activation of proto-oncogenes and/or the inactivation of tumor suppressor genes, resulting in malignant transformation of cells. loss of immune surveillance in the body; The occurrence of tumor is not only the result of a single gene mutation, but also a long-term, multi-stage, multifactorial, and multi-gene mutation accumulation process.
Benign tumors refer to the abnormal proliferation of cells in certain tissues in the body, which grows expansively, like blowing up balloons, and gradually expands and grows slowly. Because the tumor continues to grow, it can squeeze the surrounding tissues, but does not invade the adjacent normal tissues, and the tumors are mostly spherical and nodular. The capsule is often formed around, so it is clearly demarcated from normal tissue, touched by hand, pushed and moved, easy to remove during surgery, removed without metastasis, rarely **. >>>More
Tumors are different from normal tissues of the body usually, divided into benign, malignant, and somewhere in between. Malignant epithelial tumors are also known as carcinoma. Tumors have a certain association with human genes, most of which have a family history, and modern science has analyzed a variety of cancer susceptibility-related genes. >>>More
The most reliable is biopsy, aspiration or bronchoscopy to remove the biopsy and do pathological examination, which is the most accurate. If you are over 45 years old, you should go for a check-up, insurance, benign problems are not big, regular check-ups, as long as it does not suddenly increase in a short period of time or affect breathing and heart function, it is nothing; Malignancy is more troublesome, but there are different degrees of malignancy, as well as different tissue types, some are sensitive to chemotherapy, and some are better at radiotherapy or surgery, but they all have to have scientific examination results, and the best plan can be determined after the examination. >>>More
There are benign and malignant conditions of kidney tumor disease, and the actual condition of the disease depends on the actual condition of the disease. >>>More
Yes, if the tumor is at an advanced stage, well, in addition to this condition, there will also be severe pain in the body, weight loss, anemia, coagulation dysfunction, dizziness, headache and vomiting.
