Cancer: causes and effects

Cancer and factors that provoke it

Even though many people might not be familiar with this, the fact is that the cancer, which is one of the most severe diseases today, did not always exist. And no, this does not have anything to do with the fact that medicine was not developed earlier as it is today. To be more precise, the reason why cancer as a disease developed and why the number of those who are affected by it increases constantly is related to various chemicals, food additives and preservatives, as well as pesticides that became an inevitable part of our life and our diet to a great extent, and which are very toxic.

Due to the negative effect that they have on the body and the health in general, they are called carcinogens. The carcinogen that is practically inevitable today definitely includes tobacco smoke. Aside from it, gamma rays, X-rays, asbestos and vinyl chloride are also regarded as strong carcinogens. According to the results of some researches, if overcooked and overheating food is consumed for a long period of time, it will contribute to the growth of the cancer cells.

The effects of cancer

The effects of this serious disease depend on the numerous factors, among which are also the cause and the organ or part of the body that is affected. This means that the symptoms will definitely not be the same in all cases of cancer, and it does not even mean that people with the same type will develop the same symptoms. On the other side, regardless of the type of the cancer, there are only a few methods of treatment that can be used.

Since carcinogens are the main culprits for the development of cancer, it is necessary to understand how they work and why they are so dangerous. The scientists managed to prove that they have the ability to attack the cells directly, and they do that by attaching to the DNA. This further results either in some kind of alteration of the metabolism of the cells, or in the damage to the DNA. Once the DNA has been damaged, it will ultimately lead to the death of the cell since it cannot be repaired anymore. The cancer tumor forms as a result of these alterations in biological processes, or when the immune system becomes so weak that it cannot deal with the deadly carcinogens, thus allowing them to damage the DNA.
