Why tumor and cancer are not the same thing

When a malignant tumor progresses to a certain extent, it is cancer.

No, normal tissues such as the heart, kidneys, and brain can also be visualized on PET-CT. The abnormal development site is not necessarily the tumor, and inflammation and cysts will also be developed under PET-CT.

If someone has gastric cancer, it means that the patient has cancer formed by the gastric mucosal epithelium, and if the patient has gastric sarcoma, it means that the malignant tumor is not formed by mucosal epithelial cells, but may be caused by the malignant transformation of smooth muscle cells, or it belongs to the malignant lymphoma of the stomach. But it can also be said in general terms that he has cancer.

According to the cell characteristics of new organisms and the degree of harm to the body, tumors are divided into two categories: benign tumors and malignant tumors. Malignant tumors can be divided into carcinoma and sarcoma, and carcinoma refers to the malignant tumor of epithelial tissue. Sarcoma refers to mesenchymal tissue, including fibrous connective tissue, fat, muscle, vasculature, bone and cartilage tissue, etc.

Malignant tumors that occur, such as those formed by the epithelium of the large intestine mucosa, are called epithelial carcinoma of the large intestine mucosa, or colorectal cancer for short. The epithelial formation is called epithelial carcinoma, referred to as carcinoma and so on. So, if a doctor says that someone has cancer, it means that the patient has a malignant tumor.

Cancer is a type of tumor, which is generally malignant. Tumors are mainly divided into benign tumors and malignant tumors according to their pathological properties. The vast majority of malignant tumors are cancers, that is, malignant tumors in epithelial tissue or malignant tumors in mesenchymal tissues, such as sarcoma, or malignant tumors of the hematopoietic system, such as leukemia.

Cancer can be manifested as a lump, hard texture, surface ulceration, repeated non-union or tenderness, fever, bleeding and other symptoms, the cancer is mainly surgery, through surgery and postoperative pathological examination can determine the nature and stage of cancer, generally after surgery with adjuvant radiotherapy, chemotherapy and other comprehensive **, some tumors also need to cooperate with endocrine**, targeted drugs**, etc.

To put it simply, malignant is cancer, and benign is called tumor? You're going to ask whether it's malignant or benign.

Yes, tumors can be benign and malignant. Benign tumors are generally fine, but benign tumors that become malignant tumors are called cancer.

Tumors are not necessarily cancerous, some tumors are benign and some can become cancerous.

It seems that only malignant tumors are called cancer, and benign tumors are not called cancer.

Tumors are divided into benign and malignant, and cancer is malignant.

With the development of immunology, cell biology, molecular biology and other disciplines, the current biological means have included antibodies, cytokines, adoptive immunity and genes, etc., and the 21st century will be the era of tumor biology.

By mobilizing the defense mechanism of the human body, the biological body can prevent the growth of tumors and realize the "autonomous anti-cancer" of the patient's own body, which is expected to achieve the goal of completely eliminating cancer cells and becoming a major direction of cancer in the future.

Tumors are classified as benign tumors and malignant tumors. Benign tumors are usually not life-threatening. Malignant tumors are commonly known as cancers.

But even malignant tumors are not as scary as people think, and cancer is actually a relatively serious chronic disease. Many people die of cancer because of fear and nervousness, or because of inappropriateness. Because many modern methods, such as chemotherapy and radiotherapy, have greatly reduced the body's immunity and caused great damage to the body.

Tumors can be divided into benign and malignant tumors. People often say that cancer is malignant tumor!

However, some malignant tumors can also be **!

Tumors can be classified as benign and malignant. Malignant tumors are cancers.

People try to confuse tumors with cancer, thinking that tumors are cancers, but there is a fundamental difference between the two. Tumors include benign tumors and malignant tumors. A degree of malignancy between the two is also called a junction tumor.

And what we call cancer is a common name for malignant tumors. So a tumor is not the same as cancer.

There is a traitor in the body, which causes the autologous cells not to know themselves and attack themselves, which is chaos to put it bluntly.

It is said that cancer cells exist in the body of every normal person, and when the accumulation of some factors causes genetic mutations in normal cells or cancer-suppressing cells, they are transformed into cancer cells.

The essence of cancer is that it has biological characteristics such as abnormal cell differentiation and proliferation, uncontrolled growth, invasion, and metastasis.

The essence of cancer is the mutation of cells in the human body, mainly due to some pathological reasons that lead to changes in the genes of cells, so that some harmful cells appear in the human body
