It is believed that oncological diseases are associated with lifestyle (poor nutrition, sedentary lifestyle, smoking, alcohol abuse, etc.) and the environment. Now scientists continue to study this issue and conduct a huge number of studies, almost every day new facts appear regarding the development of cancerous tumors. Recently, American researchers stated that the development of malignant tumors has no connection with heredity, ecology or lifestyle that a person leads, i.e. cancer in most cases appears spontaneously, without any specific reasons. A group of specialists has already reported their discovery to a number of scientific publications.
As the researchers reported, the formation of a malignant tumor in the body occurs when cells divide incorrectly, which in most cases begins by accident. During their work, the scientists studied more than 30 types of tumors, and as a result, it was found that the process of cell division was not affected by external or genetic factors. Heredity was detected in only 1/3 of all cases, in the rest, the tumor began to develop spontaneously, without any particular reason. In addition, medicine knows a sufficient number of cases when cancer was diagnosed in healthy people without bad habits.
The assertion that frequent stress can provoke the growth of a cancerous tumor was also not confirmed. Previously, it was believed that constant nervous tension and stress are one of the main causes of oncological diseases, but a new study has refuted this opinion.
But despite their findings, scientists continue to argue that improving the quality of life and the environment will reduce the incidence of disease among the population.
By the way, science recently learned of a case of cancer infection. An atypical case of malignant tumor development is associated with infection by a parasitic worm that entered the human body through the digestive system, and then entered the lymphatic system and spread throughout the body. Experts suggested that some of the larvae did not come out with the waste products, and the penetration of the parasite into the lymphatic system provoked the development of cancer.
Also, many scientists have named radiation as one of the causes of cancer. In particular, the source of harmful radiation can be radon, which is present in bricks and concrete used in the construction of buildings; when in such buildings, a person is exposed to constant radiation, and this in turn leads to disruption of the cell division process.
Swedish experts have established in their new studies that there is a connection between a person’s height and the development of oncology – tall people are more susceptible to developing malignant neoplasms, compared to their short peers.
According to the Swedish theory, the risk of developing cancer increases by almost 20% with every 10 cm of height.
According to the experts themselves, this phenomenon can be explained by the fact that tall people have more cells in their bodies, and in addition, cancer is extremely rarely diagnosed in people with genetic dwarfism.
