Cancer (oncology)

Malignant fibrous bone histiocytoma

Malignant fibrous bone histiocytoma is a tumor of a high degree of malignancy, the frequency is not determined. The main constituent elements of the tumor are histiocyte-like cells and spindle-shaped fibroblasts present in various ratios.

Osteogenic sarcoma

Osteogenic sarcoma is a malignant bone tumor that develops as a result of malignant transformation of rapidly proliferating osteoblasts and consists of spindle-shaped cells forming a malignant osteoid.

Germinogenic tumors

Germogenous tumors are tumors that develop from the primary embryonic cells of the human embryo, from which spermatozoa and oocytes normally form.

Cancer of the uterus: symptoms

Uterine cancer, the symptoms of which can be variable, but fit into three main groups - discharge, pain and bleeding, is oncological pathology, the second most common after breast cancer.

Tumors

Tumors - excess, uncoordinated with the body, pathological growth of tissues, continuing after the cessation of the causes that caused it.

Diagnosis of cancer

Early diagnosis of cancer is the main task in oncology, determining the effectiveness of treatment and ultimately the life expectancy of the patient. This problem is especially relevant in connection with the steady growth of cancer morbidity.

Cancer Prevention

Prophylaxis of cancer is based on modern knowledge of the mechanisms of carcinogenesis. The experience of experimental and epidemiological studies indicates the existence of a direct connection between the effect of external agents, endogenous metabolites and the development of tumors with a certain latent period under their influence.

Causes of cancer

WHO identifies the following main causes of cancer: nutrition (35%), smoking (30%), sex, reproduction (10%), insolation (5%), ionizing radiation (3.5%), occupational hazards (3.5% ), environmental pollution (3.5%), alcohol abuse (2.7%), heredity (2.3%).

Classification of cancer

The clinical classification of the cancer of the TNM International Cancer Union (ICPM) is necessary to develop a methodology for the uniform presentation of clinical data. Clinical description and histological classification of cancer can play a significant role: in planning treatment; forecasting; evaluation of treatment outcomes; exchange of information between medical centers; contribute to the further study of cancer.

Professional Cancer

Occupational cancer is defined as a blastomogenic reaction that occurs as a result of a person's professional activity with regular, usually prolonged, contact with some exogenous chemical and physical agents that operate quite intensively.
