neoplasm, also called tumor, is a form of cell proliferation not controlled by the body, with a tendency towards autonomy and perpetuation.
The word "neoplasia" comes from the Greek, where neo = "new" and plasis = "cell growth, multiplication".
Neoplasms can be benign or evil, according to its potential to harm the individual.
Benign Neoplasm
THE benign neoplasm it is characterized by slow growth, is usually circumscribed by a capsule of fibrous tissue that delimits the tumor, is localized and does not infiltrate or invade neighboring tissues. In most cases the tumor can be removed completely and there is no risk of metastasis.
Metastasis it is the spread and growth of neoplastic cells in places far from their origin.
Benign neoplasms have the suffix "Oman" in its nomenclature, such as "fibroma" and "lipoma", for example. However, lymphoma, melanoma and myeloma are malignant neoplasms and are outside the rule.
Malignant Neoplasm
THE malignant neoplasm (cancer) it has an accelerated growth and has the ability to invade adjacent tissues, being able to develop metastasis.
Malignant neoplasms receive the suffix "sarcoma" in its nomenclature, as "fibrosarcoma" and "osteosarcoma". On the other hand, malignant neoplasms originating from the epithelial tissue are called "carcinoma".
