- Abstract
The tumour, or neoplasm, is an abnormal tissue mass resulting from excessive, uncontrolled and irreversible cell proliferation which continues even after the initiation stimulus has ceased. Epidemiology and incidence. Neoplasms, and among them the malignant ones, currently represent a major public health problem. It is believed that about 20% of human deaths are caused by cancers, but their incidence is undoubtedly much higher. It is believed that about a quarter of the human population will develop during their life a form of cancer. The incidence of this condition is uneven, depending on several factors: geographic factor, age, sex, race, inherited predisposition, acquiring preneoplastic lesions or conditions. Biomorphological characteristics of malignant tumours: evolutive characteristics (fast and unsteady evolution, they produce local invasion; they relapse post-intervention and give remote insemination); macroscopic characteristics - generally they have a low consistency, the tumour tissue is soft, brittle, most commonly coloured white-grey for carcinomas and reddish-haemorrhagic for sarcoma; microscopic characteristics. Criteria of assessing the prognosis of malignant tumours: degree of differentiation, tumour stage, diagnostic methods. Types of benign and malignant neoplasms: tumors of epithelial tissue (papilloma, adenoma, carcinoma, adenocarcinoma), tumors of common connective tissue (fibroma, myxoma, sarcoma), tumors of adipose tissue (lipomas, liposarcomas), tumors of cartilaginous tissue (condroma and chondrosarcoma), bone tissue tumours (osteoma, osteoclastic, osteosarcoma), tumors of muscle tissue (leiomyoma, rhabdomyoma, leiomyosarcoma and rhabdomyosarcoma), tumors of blood vessels (haemangioma and hemangiosarcoma), tumors of melanoma pigment tissue (pigmented nevi and malignant melanoma), tumors of lymphoreticular tissue (Hodgkin's and non-Hodgkin's lymphomas).
