What is benign neoplasms?
Benign neoplasma is an abnormal growth or tumor consisting of cells that are divided and reproduced independently of the surrounding normal tissue. Benign neoplasm cells do not have the typical properties of malignancy. Although cells in any neoplasm, benign or malignant, tend to proliferate faster and take longer than the appropriate normal cells, benign neoplastic cells proliferate at a slower speed than malignant cells. Benign neoplasms do not penetrate and attack the surrounding tissue, even if they are expanding locally. They do not undergo an unlimited, destructive way and do not spread through blood circulation to distant places in the body.
cell characteristics of benign neoplasm are very similar to the properties of normal cells that do not show defective cellular ripening of malignant cells. Any type of body cell can produce benign neoplasm. The fibrous capsule, providing a clear definition between the AA normal tissue tumor, usually surrounds the benign neoplasm. For this reason, benign tumors can be completely removed. Benign novotvaR, if completely removed, it will not grow back.
Benign neoplasm is usually named after its predominant cell type, followed by an extension, "-oma". For example, a benign glial cell tumor, which is supportive cells in the nervous system, is a gliom. In general, the "–oma" suffix is a benign, non -clinging nature of the neoplasm, although this may not always be the case. For example, pigmented skin cell cancer, called melanoma, is malignant.
Although many benign neoplasms are absolutely harmless, the term "benign" can be misleading. Benign neoplasms, although lack of invasive potential, can cause significant, harmful effects. In the United States, secondary tumors are approximately 13,000 deaths. Neoplasms Cells, which usually produce hormone or secretion in the body, can overproduction these chemicals, which can cause a number of health problems. In addition, he can accelerateThe growth of the benign tumor compress the surrounding tissues and damage them or relocate them.
Some benign neoplasms degenerate on cancer, probably because of other genetic material mutations. For example, a certain stain or moths of skin can become cancer over time. Many of these premalignant areas are gradually showing unusual development over time, a state called dysplasia. Most doctors recommend the excision of dysplastic lesions before reaching a malignant stage.
The symptoms of a benign tumor depend on its size, location and properties. In addition to pain, pressure and hormonal imbalances, symptoms may include abnormal bleeding, blockage of blood flow, itching and cosmetic changes. Polyps of the large intestine can prevent normal movement of waste materials over the large intestine and produce abdominal pain and swelling. Tumor expansion can erode or weaken the bone, leading to fractures from a seemingly small trauma. Asymptomatic neoplasms do not require treatment but survivingRgic excision of the whole benign neoplasm is the treatment of choice when the patient experiences symptoms.
