A colleague didn't go to work for a long time. Later, he heard that he had cancer. So, is malignant tumor cancer? Let's talk about it.

Is malignant tumor cancer

First of all, we should correctly distinguish between malignant tumor and cancer. At the same time, we should pay attention to it. In people's impression, cancer is the so-called malignant tumor. In fact, malignant tumor includes not only cancer, but also sarcoma.

Secondly, in medicine, cancer refers to the malignant tumor originated from epithelial tissue, which is the most common type of malignant tumor. Correspondingly, malignant tumors originated from mesenchymal tissue are collectively referred to as sarcomas. For a small number of malignant tumors that are not named according to certain principles, such as nephroblastoma and malignant teratoma, we often call them cancers.

Finally, tumors are divided into benign tumors and malignant tumors. Generally speaking, cancer refers to malignant tumors. Histologically, malignant tumors are divided into epithelial carcinoma, non epithelial sarcoma and hematological carcinoma. The difference between benign and malignant is often judged according to the clinical prognosis. There are many exceptions to the two, and it is often difficult to make a strict distinction. This is also determined by the environmental conditions of each tumor cell. Some scholars hold that there is a continuous stage between benign and malignant tumors, but some benign and malignant tumors, such as prostate adenoma, breast fibroadenoma, hysteromyoma, glomus tumor and so on, are tissue proliferation closely related to endocrine, nerve and other body regulatory mechanisms, so some scholars hold that they are essentially different from malignant tumors.
