Because of what does a person develop cancer?

It's not a secret for anyone that cancer is a most dangerous malignant disease that disrupts the growth of cells in the human body, turning them into cancer. For each type of tissue is considered absolutely normal, when the cells grow and divide. But if this process is suspended and new cells do not appear, then new tissues appear in the tissues. Therefore, many people are interested in information, cancer because of what appears. In this article, and consider all the nuances.

In the body of each person there is a special mechanism that is responsible for the correct growth and division of cells of all types of tissues. However, there are some factors that provoke the failure of this mechanism, thereby causing cancer. Remember, the earlier you can diagnose the disease, the more chances you have to cure it.

What is cancer?

Before to understand, the cancer because of what appears, it is necessary to disassemble the basic features of this disease. Please note that there are benign and malignant tumors. So, cancer is precisely malignant neoplasms. Characterize this disease can be as follows:

- cells begin very quickly and uncontrollably to share;

- the disease can "attack" also on neighboring organs and tissues;

- but metastases can be formed absolutely in any organs.

If this disease is simply ignored, then it will start to expand and affect neighboring organs, and for cancer it does not matter which. When the disease has passed to the metastatic level, bad cells begin to move with blood throughout the body and settle in different organs. There they take root and actively share. To treat the disease is very difficult, because even if you kill thousands of cells, but leave only one, the disease will again begin to progress.

Cancer can occur, regardless of the age of the patient. But the older it becomes, the harder it is to treat the disease. After all, people of advanced age are no longer so strong immunity, and cancer can spread through the body much faster.

Where does the cancer come from?

In fact, there are a huge variety of different causes that can lead to the appearance of atypical cells. This disease has been known for a long time, but in the past two decades, the incidence of the disease has increased dramatically and continues to grow. And this suggests that there are some factors that contribute to the emergence of this disease.

Carcinogenic factors

Carcinogens - this is one of the common causes 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 the 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's why try to avoid a long stay under the hot scorching sun.

Biological factors include some diseases. The most common of these are the Epstein-Barr virus, as well as the papillomavirus.

Chemical carcinogens

Cancer because of what appears - it's a question, answering to which you can save yourself from such a dangerous ailment. Chemical carcinogens are substances that, when ingested, can cause cancer.

Here is the list of the most dangerous of them:

- arsenic;

- various dyes;

- nitrates, cadmium and benzene;

- aflatoxin, asbestos and formaldehyde;

- also do not forget about various food additives.

A large number of carcinogens gets into the air when burning garbage, as well as burning plastic and oil. In industrial cities, air contains a huge amount of harmful substances. And the more the city is, the more carcinogens are in it.

If you consider cancer because of what appears, then do not forget about food. Do not eat too much fatty food. When buying products in stores, be sure to pay attention to their composition, because in almost all of them you can find carcinogens, which are usually denoted by the letter E. And Е123 and Е121 are considered as 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 various smoked foods, such as ham, bacon, sausage and sausages. Also, be sure to read the composition of products such as white bread and pasta. Give up popcorn, sweet sodas and ready-to-eat breakfasts.

Viruses

Viruses are one of the main causes of cancer. Most often it is caused by infections such as papilloma, polyoma, retrovirus, adenovirus and Epstein's virus - Barr. 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 a papilloma appears on the body, the appropriate tests are performed. This will help determine whether or not this malignancy is present. And only proceeding from the received information it is possible to appoint or nominate the further treatment.

A few words about radiation

Radiation is another reason why cancer occurs. To the cells of the human body began to mutate, it is not necessary to stay in a room with a high level of radiation for a long time. It will be enough and simple stay under the sun's rays. Of course, ultraviolet light in small doses is useful for human health, but in cases of excessive love for tanning, a person can develop a disease such as melanoma.

Therefore, it is not recommended to abuse trips to the solarium, and when you go to the beach, still control the time intervals under the scorching sun. Be sure to use special sun protection. And also go to the beach only in the morning and in the evening. In such a time frame, the sun affects the human skin most sparingly.

If you have large moles and other skin diseases, be sure to hide them from the ultraviolet exposure.

Hereditary factor

Heredity is another reason why a person develops cancer. If the genes work correctly, they are able to maintain normal cell division. But if a mutation occurs in the body, then this process is completely broken. If someone in the family had cancer, then there is a high probability of the transfer of the disease to the children. It is not even necessary that the parent himself has this disease. It will be enough for him to transfer the mutated gene to the offspring.

Modern medicine allows you to undergo special examinations, which allow you to identify this gene in the human body. With the help of such tests, anxiety can be reduced if someone in the family already has cancer, and also begins treatment at the earliest stages of the disease. After all, 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's cancer develops. One of the reasons is the mutation of genes, which occurs due to external and internal factors. Cell mutation can occur quite spontaneously and unexpectedly or under the influence of factors such as poor ecology, malnutrition and ultraviolet radiation.

If the gene began to mutate, then the activity of the cells begins to deteriorate, which can lead to their withering away. However, in some cases, the cell may simply not notice the mutation of the gene and continue its further existence and division. Therefore, the mutation extends to neighboring cells, which begin to work quite differently. That's how cancer can appear. Even the smallest mutation in the human body can lead to the development of severe oncological diseases.

Can I protect myself from oncology?

Why does cancer appear has been discussed in this article. But it is also very important to know whether a given disease can be prevented. Unfortunately, no one can say this for sure. But any specialist strongly recommends taking care of your health and avoiding factors that trigger the development of cancer.

Watch your health, exercise, eat right, have plenty of rest and visit the doctor on time, and then no illnesses will be terrible for you. Be healthy. And do not forget that cancer is not a sentence.
