What is malignant tumor? What is the difference between benign tumor and benign tumor?

(3) Different degrees of influence on the body: Benign tumors have little influence on the body, mainly local oppression, obstruction and endocrine disorders; Malignant tumor has a great influence, besides oppression and obstruction, it can also destroy normal tissue structure and cause infection and cachexia. 2. Malignant tumor: Malignant tumor refers to a tumor that occurs in epithelial tissue, commonly known as cancer in medicine. Different from benign tumors, malignant tumors will transfer lesions in vivo to expand the scope of infection, and their growth rate is very fast, which is not easy to be found in the early stage, and it is easy to spread in the human body and will invade the periphery ... First, the difference between benign and malignant tumors with naked eyes: The general shape of tumors is very inconsistent, which is closely related to the location and growth mode of tumors. Tumors have various shapes, which can reflect the benign and malignant of tumors to some extent. 1. Benign tumors, located on the body surface and mucosa, mostly show protuberance growth, nodular and papillary ... Benign tumors refer to tumors with no infiltration and metastasis ability. Tumors often have a capsule or a clear boundary, which expands slowly, and the tumor cells differentiate and mature, which is less harmful to the body. Benign tumor refers to the abnormal proliferation of some tissues and cells in the body, which is characterized by expansive growth, gradually expanding like a balloon, and growing slowly ... Benign tumors generally grow expansively, with many envelopes around them, which will not adhere to surrounding tissues and have good activity. Most malignant tumors are invasive, invading surrounding tissues and blood vessels, and their activity is low. Benign tumors with different prognosis grow slowly and have low nutritional requirements, so there is little ischemic necrosis in the tumor. Malignant ... Benign and malignant tumors have obvious differences in temperament and influence on the body, but for most tumors, there is no specific morphological and molecular biological index to distinguish benign and malignant tumors. The difference between them is mainly based on the abnormal morphology of pathomorphology, which is what doctors often call "pathological section", while the main difference between benign and malignant tumors is: 1, benign tumors grow slowly and malignant tumors grow. 2. Benign tumors are soft, active, with clear boundaries and do not adhere to surrounding tissues, while malignant tumors are hard, inactive, with unclear boundaries and adhere to surrounding tissues; 3, benign tumors are generally not accompanied by systemic symptoms, not quite ... In short, the benign and malignant differentiation of tumors is not mysterious, but sometimes good and evil are not absolute. Under the influence of internal and external factors, some benign tumors sometimes become malignant, such as a few uterine fibroids that grow too fast. Therefore, benign tumors with accelerated growth should be treated in time. However, some malignant tumors grow slowly, and some malignant tumors grow rapidly ... 2. Benign tumors are soft, active and clear, and do not adhere to surrounding tissues, while malignant tumors are hard, inactive and unclear, and adhere to surrounding tissues; 3, benign tumors are generally not accompanied by systemic symptoms, not harmful to the human body, no metastasis, no ... Today, let us briefly understand the difference between benign tumors and malignant tumors. Malignant tumors are unstable and grow rapidly. Sometimes it will affect the growth and development of surrounding cells, destroy the normal tissue structure, and lead to necrosis and bleeding. Benign tumors are calm and grow slowly, and rarely affect surrounding tissues. The damage to the body is minimal. however ...
