What is a malignancy? What is the difference with a benign tumor?

Health Science Qualifying Malignant tumors are often referred to as cancers. In the West, the word "cancer" is derived from the Greek word "carcinos". What does a crab look like?

It is a creature that is centered on a lump of hard lumps and has many legs sticking out of it, and is running rampant. This vividly highlights the characteristics of cancer like a crab, with teeth and claws stretched around. Therefore, the graphic of "crab" is commonly used in Western countries to represent cancer.

Malignant tumors tend to grow rapidly, have ill-defined boundaries with surrounding tissues, and are often not covered by an envelope. The most important thing is that malignant tumors not only grow rapidly, but also invade the surrounding tissues unscrupulously, and because they grow too fast and the blood nutrition is insufficient, necrosis, ulcers and bleeding often occur. Malignant tumors also like to travel long distances and migrate to distant tissues, causing spread and metastasis, and are still easy to remove after surgery.

Benign tumors grow slowly, literally – good ones, good ones. Benign tumors have a mild temper, quietly expand and grow on their own territory, usually surrounded by the protection and isolation of the envelope, with clear boundaries with the surrounding tissues, generally do not invade and destroy adjacent tissues, rarely necrosis, hemorrhage, and do not metastasize to distant places, rarely after surgical resection, and less harmful to the body. However, if a benign tumor unfortunately grows in some special parts, such as the skull, it is also very dangerous.

Because the tumor with intracranial expansion does not attack the surrounding tissues, it will inevitably compress the brain tissue, and the brain is a very delicate and important organ, in the limited space of the skull, the function of the part squeezed by the tumor will be impaired, and if it is not treated in time, it can endanger the patient's life.

Benign and malignant tumors have obvious differences in temperament and impact on the body, but for most tumors, there is no specific single morphological and molecular biological index that can distinguish between benign and malignant tumors.

The so-called tumor is a new organism formed by the long-term action of different related factors (carcinogenic factors and carcinogenic factors) of mature or developing normal cells in the body, which are overproliferated and abnormally differentiated. It is divided into benign tumors, malignant tumors and junctional tumors.

Benign tumors, commonly known as "tumors", grow slowly, have a long course of disease, and do not metastasize. Generally, larger tumors are surgically surged**, combined with traditional Chinese medicine, and the survival rate is relatively high, and some can even be cured. Nowadays, the incidence of benign tumors is very high, which is not terrible, but it needs to be surgically cut out for pathological biopsy, and the biopsy will observe the differentiation of its cells, and it needs to be rechecked regularly to prevent deterioration.

Malignant tumors originate from epithelial tissues called "carcinomas"; ** Mesenchymal tissue is called "sarcoma". Malignant tumors are more severe, develop rapidly, and have a low survival rate, and the survival rate span between various diseases is relatively large. And malignant tumors are easy to metastasize, and metastasis is divided into 4 types:

Direct metastases, hematologic metastases, lymphatic metastases, implant metastases. Malignant tumors should also be staged, the early stage is easier to treat, there is a possibility of recovery, in the late stage it is more serious, some may have to accept the reality, try to let the patient spend the last happy time.

A small number of tumors, morphologically benign, but often infiltratively grow, easy to ** after resection, and distant metastases can occur many times, such as parotid mixed tumors, etc., which show the type between benign and malignant from the biological behavior, which is called a borderline tumor.

The simple difference between benign tumors and malignant tumors is to see whether they develop rapidly, whether they are serious enough to affect life, whether there is pain, and whether the size, hardness, smoothness, and mobility of the lump are all distinguishing points, but because different tumors have different differences, it is recommended to go to the hospital for diagnosis. Pathological differences require the use of instruments, such as CT, X-ray, and imaging. You need to go to the hospital for identification by the imaging department, it is recommended not to guess by yourself and seek medical attention as soon as possible!

If you feel seriously unwell, please seek medical attention promptly!
