Cancer is a disease characterized by uncontrolled cell growth. No doubt, one of the most widespread diseases in the world and is now a disease that threatens the lives of many people. It impairs the body when damaged cells divide and form a wild group known as the tumor tissue. Cancer tumors have a very negative effect on the digestive system, circulatory and nervous and also secrete hormones that affect body functions. But there are some tumors that remain in one place and showed limited growth, which is considered to be benign. This document discusses the details focuses on cancer, causes and treatments.
There are several types of cancer can develop any part of the body including the skin, lung, colon, breast, bone, blood or nerves. The kind that affects an individual depends on the severity of the defects. The main categories of cancer, including brain cancer, blood cancer, cancer of the digestive / gastrointestinal cancer, bone cancer, breast cancer, endocrine system cancers, eye cancer, bladder cancer, gynecological cancer, head and neck cancers and respiratory diseases. Blood cancer affecting the bone marrow is responsible for the formation of red blood cells, causing leukemia and lymphoma. Another type is critical genitourinary cancer that affects the urinary tract and male genitalia. In contrast, the female reproductive system affected by gynecological cancer, such as the cervix, endometrium, ovary and vagina. Head and neck cancer is another type of cancer that affects the surface damp neck or head, mouth, nose or throat. Another type of respiratory cancer, which affects the lungs. Skin cancer is one of the other types, and especially as a result of exposure to ultraviolet rays of the sun.
Cause cancer and many who are still not known. This best explains why cancer has become one of the world's terrible murderer who killed many innocent people. Understand that the human body consists of billions of cells is important in the study of this disease. The cells can be defined as the basic building blocks of tissue minute. As a matter of fact people begin their existence as a single cell to grow and then a process known as replication and will be divided into two cells and so on until the fully formed human. The cells are not found only in humans but also in all living things.
Cancer develops from cells of the body. Has a typical copy when they are needed by the body and die when no longer needed. Cancer tends to begin when the growth of these cells beyond the control and cell division occurs quickly so critical that can not be controlled. Other reasons may be that some cells do not die. The causes of cancer, including excessive alcohol consumption, chemicals and other benzene, exposure to sunlight, obesity, viruses, radiation and sometimes the problems of genetics. In addition, there are a number of environmental toxins such as aflatoxin and some poisonous mushrooms. Aflatoxin refers to a particular class of toxins that grow on peanut plants. Death of cells must be fixed and must be controlled by normal body processes. Cancer cells die, but not often, but continue to grow even when the body does not need them. This contributes to the growth of control cells.
Treatment of cancer requires a different approach depending on the type of cancer is an issue. This helps determine your level, how much has grown and to see whether the tumor has spread from the site begins. It is also important that the symptoms observed in to ensure that victims who suffer from cancer and any other form of disease. Similar treatment, the symptoms depend on the type and location of the cancer. Cause of lung cancer, such as chest pain, cough and shortness of breath. Colon cancer, especially lead to diarrhea, constipation, blood in the stool. It is sad that some cancers do not have any signs, such as pancreatic cancer has symptoms only when the disease is advanced.
If the cancer is confined to one area and not spread, it is usually treated with surgery. Surgery is also used for skin, breast, lung and colon cancer. It is also used when the cancer has spread to lymph nodes. When all the cancer can not be removed, radiotherapy, chemotherapy or both apply. Highly focused radiation involves high energy rays to destroy cancer cells in them. Chemotherapy, but change the cell division process, which removes the cancer cells. There are several types of cancers such as lymphoma, cancer that attacks the lymph nodes, which can not be treated with surgery alone, but require a combination of chemotherapy and radiation. Other types of treatment, including immunotherapy that targets the immune system to resist therapy, tumor hormonal change hormone production stops or kills cancer cells and gene therapy to replace defective genes function to detect the causes of cancer.
Because of the high risk posed by cancer, advanced treatment is paramount. New progress has been made in the treatment of lung cancer and is known as the standard of care. This will remove the tumor and then treat the patient for many years. Other advance is the discovery of T-cell patients has been developed by genetic scientists at the University of Pennsylvania. Is a kind of white blood cells that attack cancer cells in advanced stages of the general type of leukemia.
In addition, cancer can be considered as one of the main killers of contemporary societies. There are so many cancers are classified according to the organ affected. Detect the symptoms and treatment of cancer is very difficult and that best describes why he became a major challenge in the community. Cancer treatment can be done in different ways, including surgery, radiotherapy, chemotherapy, hormones and gene therapy. However, it has proven ineffective and T-cell findings give hope for the future looks bright.
