Cancer is an overgrowth of diseased cells that develop independently of the whole organism’s neuroendocrine control, have broad variations in tissue cell structure and properties, are able to multiply infinitely, and pass to derivative cells their newly acquired properties.
Which Cancer is the most dangerous?
History Cancer develops as a consequence of malignant transformation of normal cells that uncontrollably proliferate and lose their apoptosis capacity Malignant transformation is caused by one or more mutations which, if the cell boundaries are not established, lead to disruption of the apoptosis mechanism.
When such a transformation is not identified by the body’s immune system, the tumour will continue to develop and metastasize. In all organs and tissues, metastases can arise. Metastases in the bones, brain, liver and lungs most frequently occur. And uncontrolled cell division can result in tumours that are benign. Cancer does not metastasize, does not invade other organs and is harmless to the body, unlike benign tumours.
Benign tumours, however, frequently develop into malignant tumours, after analyzing histological tissue, the final cancer diagnosis is made by a pathomorphological.
Surgical surgery, chemotherapy and radiation therapy are recommended after diagnosis. Specific medication is recommended for each tumour due to the advancement of medical science.
Cancer that is untreated progress to lethal flow. The majority of tumours are untreatable, but their treatment depends on the tumours’ form, spread, and level. Cancer occurs at all ages, but in the elderly most frequently. In developing countries, this is the leading cause of death. Many tumours, including tobacco, cigarette smoke, ionizing radiation, ultraviolet radiation, and certain viruses, are caused by environmental factors.
Many forms of cancer, which are listed according to the position of the organism, are identified. Cancer transformation is undergone by primary tumour cells, and the clinical symptoms are clearly evident in the patient. Scientists who study and treat cancer in medical research call oncologists.
Before the formation of a conscious person, cancer was known for a long time. In 1932, in Kenya, anthropologist Louis Leakey noticed the side of the modern man, who is believed to have been diagnosed with a form of cancer.
In addition, pathological changes in the remains, similar to bone, nasopharyngeal, breast, and melanoma tumour’s, were noticed by the ancients. Cancer has always been a human experience, portrayed from an early age in literature. Treatment of tumour’s 1600 years BC Written in clay tablets in ancient Greece, according to the records of ancient scientists.
This record lists and treats heartburn as a treatment for many types of breast cancer. Additionally, arsenic has been used to treat superficial cancer in Egypt. A similar record was left by the Ramayana:
the treatment was carried out surgically using arsenic oil. The word cancer derives from the term “carcinoma” that Hippocrates invented, meaning perifocal inflammation, meaning cancer. As it appears like two crab forks, Hippocrates called the tumour carcinoma. And the word ‘oncos’ was invented by him. The cancers of the breast, rectum and nasopharynx were identified by Hippocrates.
Depending on the degree of operation, the wound should be treated with oil containing vegetable oils and arsenic after the surgical removal of the tumour. They had the power to destroy the remaining cell tumour’s, probably. Internal tumours were not treated by Hippocrates, since surgery destroys the patient faster than cancer.
Roman doctor Avl Cornelius Celsius In the first century, it was proposed that the tumor should be surgically removed in the first stage of treatment and that no treatment should be given in the final stage. He translated the Greek word “k” into Greek Galen was the scientist who used the word ‘oncos’ to describe cancer and coined the term modern oncology as well. While cancer was theorized until around the mid-nineteenth century, there was no knowledge in the body about the mechanism of its growth.
The German physician Rudolf Virchow contributed to the definition of this method, explaining that, like cancers, several factors in the production of cancer can be identified: chemical factors; physical factors; Biological factors; Chemical factors Other types of tumours have been shown to grow under the influence of different chemicals.
For instance, growth has been found to be more frequent depending on the occupation of individuals (among workers producing aniline paints, paving roads). Carcinogens are called chemicals which cause growth. Multi-cycle aromatic hydrocarbons (dimethylbenzanthracene, phenanthrene, 3, 4-benzpyrene, etc.); cyclic amines (naphthylamine, benzidine); inorganic chemicals (chromium, lead, nickel, beryllium, arsenic, cadmium, etc.) comprise more than 1,000 chemical carcinogens. Tobacco smoke produces many of these carcinogens. Hence, smokers are more likely than non-smokers to develop lung cancer.
Physical variables are applied to ionizing radiation, ultraviolet radiation, neutrons and protons, etc. Cancer in almost all organs can be caused by ionizing radiation, but most commonly — skin and bone tumour’s, leukemia, and endocrine tumour’s (breast carcinoma cancer). The major inducer of melanoma is prolonged exposure to sunlight (its ultraviolet spectrum) in exposed areas of the skin (head, neck, arms). Yellow individuals with light skin and hair are more susceptible in this regard,
Biological Factors Three-dimensional Papillomavirus Reconstruction Oncoviruses are biological factors. In animals, tumours are known to cause several known DNA-causing tumours (such as SV40 monkey virus) and RNA or retroviruses (such as Raus sarcoma virus).
Some human tumours have been confirmed to have viral aetiology: Berkitt lymphoma, nasopharyngeal carcinoma (Epstein-Barr DNA virus), cervical carcinoma (papillomavirus), and adult T-cell leukaemia (H-cell leukaemia), etc. In general, for a small group of human cancers, viruses are “responsible”
Three stages of cancer growth (at the cellular level) are characterized by pathogenesis: initiation-onset; promotion-continuance, progress; progression-development. Primary cell damage is characterized by mutations in one of the genes that, under the influence of different chemical and physical factors, control cell proliferation. The cell is “initiated”, that is, it is able to divide indefinitely, but to show this potential requires additional conditions. A healthy cell becomes an “initiated cell” for many reasons:
