Causes of cancer. Causes of cancer of the cervix, stomach, breast and other organs

Cancer is one of the most terrible diseases that exist today. The causes of its occurrence can be very diverse, and their number is even greater due to the fact that there are many types of cancer. Considering the modern ecological situation, many people are at risk of disease. Therefore, even for those who are not aware of this ailment, it will be useful to know the causes of cancer, its types, symptoms and ways to fight it.

Cancer and the causes of its occurrence

By itself, cancer is a malignant tumor that develops from the epithelial cells of various organs that are at risk of developing this disease. It is very important to detect the disease in time, as in the early stages it can be localized and treated or removed, while in the last stages the therapy is impossible, and the lethal outcome is inevitable. Therefore it is extremely important to know the causes of cancer, as well as its symptoms, because, based on this knowledge, you can determine the approach of danger. If you have certain symptoms of the disease, and they will coincide with the causes, then you will definitely need to go to the cancer center. There, the causes of cancer and ways to treat it are known thoroughly, so you can transfer health care to the hands of real professionals. As already mentioned, in the early stages many types of cancer can be treated or at least slowed down their development. Therefore, it is worthwhile to dwell in more detail on the different types of this disease and to consider the causes of the development of cancer.

Cancer of the stomach and its causes

To begin with, stomach cancer is one of the most common types of this disease, and it suffers from a huge number of inhabitants of the earth. This kind of ailment is dangerous because it can begin to develop in absolutely any part of the stomach, after which it will hit the entire organ, and then move on to others.

The causes of stomach cancer are still being investigated, but scientists can not give an exact answer. They only highlight the main possible sources, as well as the underlying factors of the onset of the disease. Causes of stomach cancer may be lurking in nitrates and other similar substances that can enter the body through food. These are carcinogenic substances that cause the development of a cancerous tumor. Also, the direct use of acute and hot food can become a direct cause of gastric cancer. In addition, the stomach ulcer can easily be transformed into cancer.

How to treat stomach cancer

Having considered the causes of gastric cancer, it can be safely said that the main symptom will be severe pain in the said organ. Therefore, we should not wait and hope that someday everything will pass by itself. At this time, a tumor can grow in your stomach, which, until it has reached a large size, can be removed by surgery, and the disease itself is treated with chemotherapy. But when the tumor reaches inoperable size, it remains only to take drugs that can slow its growth and the development of the disease, prolonging the life span.

Female cancer: a tumor in the uterus

Women are susceptible to the development of many types of described ailment, and the main one, which is not observed in men, is uterine cancer. Of course, this is a terrible disease that you do not want any woman, but it is quite common. The causes of cervical cancer are very different, but the main thing is considered to be cervical erosion. Constant erosion, peptic ulcer disease can trigger the onset of cancer, and venereal diseases are also a great danger. They are dangerous in themselves, but at the same time can cause cancer.

Indirectly, the causes of cervical cancer include the papilloma virus, because in itself it does not cause serious damage to the body, but studies have shown that it was found in almost all women with uterine cancer. Another serious cause of cancer in women is frequent abortions.

Fighting cancer of the uterus

Cancer itself is an incredibly dangerous disease, but if it is located in the uterus, the danger increases at times. The fact is that if the disease does not fight from the very beginning, then in the end the woman will lose her reproductive function. Even if the uterine cancer was recognized in the early stages, the reasons were established, no one can guarantee that the woman will be able to bear, having recovered from the disease. Treatment should be done, and most often it is based on a combined method - combined surgical intervention, radiation therapy and the adoption of special chemicals.

Another variant

In addition to cancer of the uterus, women suffer another kind of this ailment - in this case the chest is affected. One of the most common causes of death is breast cancer in women, whose causes are often reduced to heredity. There are also cases of this disease in women who have given birth too late, as well as those who have had too early menstruation or too late came the menopause. But most of the cases are connected with heredity, it should be noted that, as a rule, breast cancer occurs in women over fifty.

A huge impact on the likelihood of the disease is having a way of life of the fair sex - her diet, alcohol or tobacco and so on. Thus, a woman can significantly reduce the likelihood of breast cancer if she does not destroy her health.

Is it possible to cure breast cancer?

Very often, this ailment is accompanied by a complete removal of the breast on which the tumor has arisen. This can be avoided if the cancer is detected in the early stages and immediately turned to the oncologist - then the complex application of radiation and chemotherapy can destroy cancer cells, but more often it is necessary to completely or partially remove the affected part of the body. Even considering that breast cancer in many cases arises because of heredity, it is not worth provoking its early manifestation of poor diet and lifestyle.

Disease without a tumor

Among cancer diseases, most often there are those forms of cancer that have specific tumors that can be seen, in some cases even to feel, and also to remove. The absence of a specific tumor makes blood cancer one of the most dangerous - at least for the reason that the problem can not be cut, and therefore, the surgical method and radiation therapy can not be applied. The causes of blood cancer are the following: the effects of radiation, poisons, chemicals. All this can affect the blood cells formed in the bone marrow, and enough that only one cell has become cancerous. They begin to ply around the body, causing him serious harm, which is incompatible with life.

Difficulties in treating blood cancer

As it was already said before, it is impossible to perform an operation to remove a tumor with this disease, since it is not present as such. It is in the whole body, represented by infected blood cells, so the only effective way in the fight against the disease is powerful chemotherapy. In the course of it, powerful chemical preparations are sent through the blood, which kill the infected cells. However, the chances of success are not too great, since infected cells in the bone marrow can remain, starting to re-produce other cancer cells. Therefore, chemotherapy for blood cancer often only prolongs the patient's life.

Saving can be an extremely risky operation for bone marrow transplantation. The brain that is in the spine of the patient is completely removed along with the carcinogenic cells, only the patient is previously treated with chemotherapy. After this, the bone marrow of the donor is transplanted to him. The patient at this time is in a hard quarantine, since without the bone marrow his body is exposed to all possible viruses.

The problem of smokers

Lung cancer is the most common type of cancer in the world, this is the disease most affected by cancer. The causes of lung cancer, surprisingly, may be different, although the main thing is still smoking. Eighty percent of people with lung cancer got this disease because of tobacco smoke. The reason is very simple - along with smoke in the lungs comes hydrogen peroxide, which sends a signal to the lung cells about what needs to be updated. They begin an update, which is not necessary for the easy, because of what the cancerous tumor begins to form. Therefore, it is never too late to quit smoking, because if smoke does not manage to cause lung cancer in you, smoking cessation minimizes the risk of its occurrence. But it should be taken into account that the matter here is not in cigarettes, but in tobacco smoke, so replacing cigarettes with cigars or tubes will lead to nothing.

It should be remembered that non-smokers also suffer from lung cancer. This includes passive smokers, that is those people who do not smoke on their own, but for some reason communicate with people who are dependent on nicotine. The population of megacities falls into the risk group, because smog, carbon monoxide and other harmful substances in the air fall into the lungs, causing cancer. Most of this ailment is worth to be feared by those who have chronic lung diseases, since weakened organs are most prone to negative effects.

Is it possible to get rid of the problem?

Lung cancer can be overcome in the early stages, when the tumor is not too large and localized in one lung. Then there is a chance with the combination of radiation and chemotherapy with the addition of surgery to get rid of the tumor and cancer cells in the affected organ. However, the overall picture remains sad, because virtually no smoker does not pay attention to the symptoms of lung cancer - cough, shortness of breath, chest pain, as they accompanied him all his life, without them it is impossible to imagine the process of smoking. As a result, a person ignores these symptoms, considering them to be normal, and the ailment continues to develop, spreads into another lung, penetrates into the lymph nodes and spreads through the body, thereby prescribing the patient a death sentence. Therefore, timely detection of lung cancer is the key to its treatment.

Cancer in the polyp

The intestine is also at serious risk of tumor damage, with rectal cancer developing in polyps-formations on the walls of the intestine, arising for a variety of reasons. Ordinary polyps are easily removed - they are cut off, and then cauterized so that the walls of the intestine do not bleed. However, with polyps that carry cancer cells in them, everything is much more complicated, since this ailment can not be destroyed simply by getting rid of the polyp. Naturally, surgical intervention, involving the removal of cancerous tumors, is necessary, but not it is the main means in eliminating the problem.

We will talk about the fight against intestinal cancer a little later, right now we need to consider the causes of rectal cancer. As in many cases, one of the main sources is heredity, but the disease can either manifest itself, or not manifest itself - depending on whether there are incentives for this. To the causes of the disease can be attributed to drinking alcohol, smoking, eating unprocessed meat, lack of useful foods in the diet, as well as a sedentary lifestyle. All this can provoke the appearance of colon cancer.

Urgent treatment

Unlike the same lung cancer, intestinal cancer can not be overlooked. This disease is most often accompanied by intestinal obstruction due to the abundance of polyps on the walls of the bowel or because of their large size. Therefore, intestinal cancer, as already mentioned, requires surgical intervention to remove polyps. However, the attack on harmful cells causes chemotherapy, which is the main means in the fight against colorectal cancer. All polyps must be surgically removed, since even from benign formations cancer may develop after a while.
