It's no secret that cancer is a dangerous malignant disease that disrupts the growth of cells in the human body, turning them into cancer cells. For each type of tissue, it is considered absolutely normal when the cells grow and divide. But if this process stops and new cells do not appear, then tumors appear in the tissues. Therefore, many people are interested in information, because of what cancer appears. In this article we will consider all the nuances.
In the body of each person there is a special mechanism that is responsible for the proper growth and division of cells of all types of tissues. However, there are some factors that trigger the failure of this mechanism, thereby causing cancer. Consider, the earlier you can diagnose the disease, the more chances you have to cure it.
What is cancer?
Before you understand the cancer because of what appears, you need to analyze the main features of this disease. Note that there are benign and malignant tumors. So, cancer is precisely malignant neoplasms. This disease can be characterized as follows:
- cells begin to divide very quickly and uncontrollably;
- the disease can also “attack” neighboring organs and tissues;
- but metastases can form in absolutely any organs.
If this disease is simply ignored, then it will begin to grow and affect neighboring organs, and for cancer it does not matter which ones. When the disease has passed to a metastasis level, bad cells begin to move with the help of blood throughout the body and settle in different organs. There they take root and actively share. It is very difficult to treat the disease, because even if you kill thousands of cells, but leave only one, the disease will begin to progress again.
Cancer can occur regardless of the age of the patient. But the older he gets, the harder it is to treat the disease. After all, elderly people no longer have such strong immunity, and cancer can spread through the body much faster.
Where does cancer come from: causes
In fact, there are a huge variety of reasons that can lead to the appearance of atypical cells. This disease has been known for a long time, but in the last two decades, the percentage of the onset of the disease has increased dramatically and continues to grow further. And this suggests that there are some factors that contribute to the appearance of this disease.
Carcinogenic factors
Carcinogens are one of the common causes of the development of cancer cells in the human body. There are carcinogens that can not only increase the rate of cell division, but also have a mutagenic effect, damaging the structure of DNA itself. These substances can have three types of origin: physical, biological and chemical.
The first type includes ultraviolet and X-rays, as well as gamma radiation. That is why try to avoid a long stay under the hot scorching sun.
Biological factors include some diseases. The most common of these are Epstein-Barr virus, as well as papillomavirus.
Chemical carcinogens
Cancer because of what appears - this is a question by answering which you can protect yourself from such a dangerous ailment. Chemical carcinogens are substances that, when ingested, can cause cancer.
Here is a list of the most dangerous of them:
- arsenic;
- a variety of dyes;
- nitrates, cadmium and benzene;
- aflatoxin, asbestos and formaldehyde;
- also do not forget about various food additives.
A large number of carcinogens enter the air when burning garbage, as well as burning plastic and oil. In industrial cities, the air contains a huge amount of harmful substances. And the bigger the city, the more carcinogens in it.
If you consider the cancer because of what appears, then do not forget about food. In no case do not eat an excessively large amount of very fatty foods. When buying products in stores, be sure to pay attention to their composition, because in almost every one of them you can find carcinogens, which are usually denoted by the letter E. Moreover, E123 and E121 are considered the most dangerous for human health.
Pay attention to food
If you are interested in what causes cancer, then first of all think about what you eat. Try to avoid a variety of smoked foods such as ham, bacon, sausages and sausages. Also be sure to read the composition of foods such as white bread and pasta. Avoid popcorn, sweet soda and cooked breakfasts.
Viruses
Viruses are one of the main reasons why cancer appears. Most often, infections such as papilloma, polyoma, retrovirus, adenovirus and Epstein-Barr virus lead to it. In oncology, fifteen percent of all cases of cancer are viral diseases. Quite often, infections that can affect the development of cancer just sleep in the human body and can be passed on to the next generation.
Experts advise that, when papillomas appear on the body, they should be tested. This will help determine whether this formation is malignant or not. And only on the basis of the information received, further treatment can be prescribed.
A few words about radiation
Radiation is another reason why cancer appears. For the cells of the human body to begin to mutate, it is not necessary to be in a room with a high level of radiation for a long time. A simple stay in the sun will suffice. Of course, ultraviolet in small doses is useful for human health, but in cases with excessive love of sunbathing, a person may develop a disease such as melanoma.
Therefore, it is not recommended to abuse trips to the solarium, and when hiking on the beach, still control the time intervals under the scorching sun. Be sure to use special sun protection products. And also go to the beach only in the morning and in the evening. In such a time frame, the sun acts most gently on human skin.
If you have large moles and other skin diseases, be sure to hide them from ultraviolet exposure.
Hereditary factor
Heredity is another reason why a person has cancer. If genes work correctly, then they are able to maintain normal cell division. But if a mutation occurs in the body, then this process is completely disrupted. Pay attention to the fact that if someone in the family had cancer, then there is a high probability of passing the disease on by inheritance to children. Moreover, it is not even necessary for the parent himself to have this disease. It will be enough for him to transmit the mutated gene to the offspring.
Modern medicine allows you to undergo special examinations that allow you to identify this gene in the human body. With the help of such tests, you can reduce anxiety in the event that someone in the family is already ill with cancer, and also begin treatment at the very first stages of the disease. Indeed, in this case, getting rid of the disease will be much easier.
Mutations in human genes
Many people are interested in the question of how a person develops cancer. One of the reasons is considered a gene mutation, which occurs due to external and internal factors. Mutation of cells can occur completely spontaneously and unexpectedly, or under the influence of factors such as poor ecology, malnutrition and ultraviolet radiation.
If the gene begins to mutate, then the activity of cells begins to deteriorate, which can lead to their death. However, in some cases, the cell may simply not notice the gene mutation and continue its further existence and division. Therefore, the mutation extends to neighboring cells, which begin to work in a completely different way. That is how cancer can appear. Even the smallest mutation in the human body can lead to the development of severe cancer.
Is it possible to protect yourself from oncology
Why cancer appears was discussed in this article. But it is also very important to know whether this disease can be prevented. Unfortunately, no one can say for sure. But any specialist strongly recommends taking care of your health and avoiding the factors that provoke the development of cancer.
Watch your health, exercise, eat right, have more rest and visit the doctor on time, and then you will not be afraid of any illnesses. Be healthy. And don't forget that cancer is not a sentence.
