The word "cancer" must be familiar with everyone. This is a chronic disease that is difficult to treat and extremely fatal!
As my country gradually enters an aging country in recent years, changes in living environment, changes in living habits and diet, and the high incidence of chronic diseases, the cancer rate in my country is also increasing day by day. Just in 2015, the number of new cancer patients in my country reached 4.292 million, and the number of deaths from cancer exceeded 2.814 million, !
But even though the form of cancer is so severe, many people still don’t know what kind of disease it is. We don’t even know whether a malignant tumor is cancer. Today, we will help solve the problem of cancer together!
First of all, , We need to understand what tumor is!
The essence of tumor is a genetic disease of , , but it is not a genetic disease. In fact, everyone can completely regard tumors as new organisms inside the human body. Under normal circumstances, the cells inside our body are continuously metabolizing and being normally regulated by the body cells. The cells that form tumors are affected by various tumorigenic factors, and the genes have changed;
The cells after mutated have escaped the normal regulatory measures of the body. and no longer comply with the rules of metabolism . Instead, began to monoclonal hyperplasia in the body, and formed a new biological .
Since this organism is mostly a local lump state , it is also named tumor. , a new organism, has no benefit to the human body. Instead, it will continue to steal nutrients, destroy or compress tissues, so tumors are a disease!
Secondly, everyone should know that there are two main categories of tumors, namely benign and malignant tumors!
Clinically, according to the differences in the biological characteristics and hazards of the tumor, tumors are divided into benign and malignant. The so-called benign tumor refers to a type that has a envelope on the surface, has a slow growth rate, is very clear from the surrounding boundaries, and does not cause infiltration or metastasis. It is often not harmful to human health!
Which malignant tumors are different. Although the pathogenesis is similar to benign tumors, mutated cells of malignant tumors also have other abilities, such as invasion and infiltration into surrounding tissues, metastasis with blood circulation, etc. In addition, cells will also produce harmful substances, destroying the normal function of the organs, and ultimately leading to complications, organ failure and death!
Finally, malignant tumor = cancer, but not all cancers are tumors!
In fact, in clinical practice, cancer can generally refer to all cell mutations and malignant proliferative diseases in the body , which has multiple pathological types in clinical practice. What we call cancer in daily life is basically cancer that is derived from epithelial tissue, such as squamous cell carcinoma , adenocarcinoma , etc.
If originates from malignant in interleaved tissue, it is called sarcoma . A few tumors are not named according to the above principles. They originate from the body's naive tissue or neural tissue . clinically calls it blastoma;
In addition, abnormal cells appearing on the blood system proliferate , such as leukemia is a typical non-tumor malignant , which is also clinically called "blood cancer" . In addition, some malignant myeloproliferative diseases of can also be called cancer ! In general, malignant tumors can be called cancer, but cancer may not appear in the form of a tumor.
Written in the end: Up to now, my country's medical community still has no treatment method to completely cure cancer and fall into one blow.
, and affected by the characteristics of cancer itself, the early diagnosis rate of cancer in my country is also quite low. More than 2/3 of the 4 million new cancer patients have entered the advanced stage every year. Therefore, in life, everyone has to be more vigilant about cancer. For some high-risk groups, it is necessary to conduct regular anti-cancer screening.
