Tumors, benign and malignant neoplasms
Mankind knows many disasters that have befallen entire nations. Smallpox, cholera, flu epidemics, famines, wars. But they were all and are temporary. More than 70 years ago, World War II ended, a tragedy that befell nations and lasted for almost six years. The war has shown that health care has powerful means of healing wounds and infections. But after the war there was a problem with the treatment of tumors. Healthcare has focused all its efforts on the prevention and treatment of tumors. The fight against malignant tumors has become not only the most important but also the most difficult problem of medicine.
The etiology and pathogenesis of the tumor, the role of chemical and physical agents, the importance of viruses in the etiology of tumors, genetic factors, features of morphology and biochemistry of the tumor cell are currently being studied. Many studies are devoted to the early detection and timely treatment of malignant tumors, the development of antitumor drugs, original methods of radiation and combination therapy.
The main tasks of oncology are scientific development of the etiology and pathogenesis of malignant growth, diagnosis of malignant neoplasms, surgical and combined treatment and prevention of malignant tumors. The term “tumor” means excessive tissue development. In contrast to various swellings and “false tumors” caused by inflammation, metabolic disorders and exudation or transudation, the tumor has its own cells. Moreover, reproduction is unlimited, uncoordinated – and therefore, not physiological, but pathological.
Every cancer has its own pre-cancer, but not every pre-cancer turns into cancer.

- Cystic mastopathy
- Cervical erosion
- Scars after burns, etc.
All tumors are divided into two groups: benign and malignant.
Benign tumors are tumors that, when they arise, continue to be stable, are not prone to infinite growth and changes in tissue structure, do not pose an immediate threat to life and consist of mature differentiated cells. Examples: fibroadenoma, lipoma.
Malignant tumors are pathological growth of cells not coordinated with the growth of normal tissues, which continues after the cessation of the causes that caused it.
Malignant tumors have basic properties: in clinical course – unrestrained growth and in morphology – they consist of immature atypical cells (undifferentiated). They do not have a separate growth (capsules). Able to metastasize and recur.
According to the nature of the main tissue from which the tumor develops – tumors are divided into two groups: the first group – true. The second group of tumors is hemoblastoma of tumors from liquid tissues. Real – solid tumors are divided into two groups depending on tissue origin – tumors of epithelium, endothelium – they are combined in the name – cancer. And another group of tumors arising from connective tissue – sarcoma.
In the name of tumors, their tissue origin is reflected more often. As a rule, the root of the word means the name of the tissue from which the tumor originated, and the suffix -oma (from oncoma) joins the root. Tumors that develop from muscles are called fibroids, from blood vessels – angiomas, from nerves – neurinomas, from bones – osteomas. If the tumor originates or consists of a combination of two or more tissues, the name has a double root of the names of two tissues and one suffix – “oma” – neurofibroma, fibromyoma, osteosarcoma, fibroadenoma, myosarcoma, angiosarcoma, etc.
Impressions by gender and age
Benign tumors are equally common in young and old age, and malignant – more often in old age. Both men and women die and are affected by malignant tumors. The localization of tumors is not the same. Thus, men are more likely to die from malignant tumors of the stomach, esophagus, lungs, lower lip, and women from malignant tumors of the cervix, ovaries, breast, thyroid.
Colon and rectal cancer are equally common in both men and women.
Epithelial tumors, ie cancer, are more common in the elderly, and connective tissue (sarcomas) at a young age. But all this is quite relative. It is said that cancer has become younger and more impudent and has recently occurred in 18-20 years. And age should not reduce the doctor’s vigilance.
