Cancer is a disease capable of affecting any area of the body

Cancer is a disease capable of hitting any area of the body. This name refers to more than a hundred ailments.

As medical practice shows, about forty percent of cases of cancer is a disease of smokers. Moreover, according to statistics, one in three people has this defeat in a certain period of his life.

In the human body are different types of cells that form those or other organs. Normal, healthy cells multiply by division when they are needed by the body. In case of uselessness, they die.

Cancer is a disease that occurs as a result of cellular disorders. It is characterized by the presence of only a process of rapid cell division.

Tumors that do not penetrate into other tissues and do not spread to other parts of the body are related to benign formations. As a rule, their growth is rather slow. They include cells that are very similar to healthy cells.

Tumors that invade nearby tissues and spread to other areas of the body are related to malignant formations. This is cancer. The disease is characterized by greater aggressiveness, faster growth. A malignant tumor can spread through the lymphatic and circulatory system to other areas of the body. This process is called "metastasis."

Symptoms of malignant neoplasm appear depending on its location and type. Thus, lung cancer provokes a cough, tenderness in the chest, shortness of breath. With the development of a malignant tumor in the colon, diarrhea, impurities of blood in the stool or constipation is noted.

In some cases, the cancer does not manifest itself. So, for tumors in the gallbladder, the absence of symptoms is observed until the onset of the neglected stage.

However, in most cancers, the following symptoms appear:

- fatigue;

- chills;

- an upset of appetite;

- fever;

- increased sweating (especially at night);

- malaise;

- weight loss.

Experts classify about two hundred different types of cancer. Diseases can affect various organs and tissues of a person. Malignant neoplasms differ in the type of cells from which they develop.

The cause of cancer development is in most cases a combination of risk factors. One of the most significant is age. As medical practice shows, about two thirds of newly diagnosed cases of malignant tumors occur in patients aged sixty-five years and older.

Specialists define primary cancer (the area where the tumor starts to grow) and secondary. Cells can spread and give metastases to other areas of the body. This condition refers to a secondary malignant neoplasm.

When diagnosing the disease, blood tests, MRI, ultrasound, CT, endoscopy and cystoscopy are used. Research activities are conducted depending on the manifestations and the site of the lesion.

Cancer. Treatment.

It should be noted that a malignant tumor is not an infection. Therefore, infection of the disease can not occur.

The oncologist doctor decides how to treat cancer. The choice of the therapeutic method, mainly depends on the type and stage of the malignant neoplasm. The most common methods of treatment of the disease, such as radiation therapy, surgery and chemotherapy.

As a result of using methods to influence the disease, it is possible to eliminate the disease, alleviate the symptoms, increase the likelihood of recovery, prevent the further development of cancer, thus prolonging the patient's life.
