Cancer is one of the most serious diseases in our world, which affects humans and did not find a panacea that completely eliminates the disease until now. Cancer is a disease that affects the cells of the body. The body's natural cells grow and are organized in a systematic manner by the genes present in the nucleus of the cell. A defect in the genetic makeup of this cell loses control and control of these processes, leading to the rapid growth of randomly infected cells, the division of cells one after the other, cancer is a generic term that describes more than 100 types of these diseases.
The cancer and tumors that form with it divide into two parts: benign tumors, which stand at a certain extent, and do not spread away from the place of origin, which is not serious if detected and treated quickly and removed from the body, cancerous malignant tumors spread in parts of the body can not be controlled, and ends Often by the death of the infected. [1] However, medical advances have helped to try to find simple solutions to this disease through early detection, chemotherapy and other treatments to help the patient to live normally during the illness. However, cancer remains one of the most serious and deadly diseases Humans.
The most dangerous types of cancer are the risk of cancers according to the survival rate of patients alive within five years of infection, or the amount of life-saving during the year, and the lower the survival rate increased the risk of cancer; which cancer has a survival rate less than 50% is considered a cancer Dangerous and deadly, these are the most dangerous cancers:
Pancreatic cancer is one of the most serious cancers of the pancreas. Some studies have shown that 8 out of every 100,000 people a year are diagnosed with the disease. About 39,000 people die from pancreatic cancer every year because of their inability to deal with this serious disease. Its early stages, therefore, lead to rapid death. This disease occurs in the pancreas where it affects and disrupts its work, and then moves to other parts of the body is important as the liver. Eating too much red meat and saturated fat is one of the most dangerous factors for this disease. Age, smoking and diabetes play a role in increasing the risk of this disease. This disease is the fourth most common cause of death in the world. The survival rate is only 6%.
Lung cancer Lung cancer and trachea are one of the most dangerous and most prevalent cancers. More than 1.3 million new cases are diagnosed each year, with an estimated annual death rate of 1,800,000 people, while survival is 17%. The disease affects the respiratory system, smoking is the main factor of the infection, in addition to some chemical and industrial volatile, and the most important symptoms is chronic cough, which can be accompanied by blood out with phlegm.
Colon Cancer Colon cancer is also one of the most serious cancers, a cancer that affects the large intestine, also called "colon cancer rectum". Alcohol and its addiction are the main cause of the disease. Smoking, eating fatty foods and genetics are among the most common factors that increase the incidence of the disease. The number of new infections is estimated at 1.4 million annually and the number of deaths is 694 thousand annually. The most important symptom of this cancer is the change of bowel movement and blood flow with stool.
Breast cancer Breast cancer is the first cancer in women. 1.7 million cases are diagnosed every year, while the number of deaths is 500,000. The survival rate varies from one country to another, but in general it is 75%. Cancer is a growing cancer, but early detection is easy to treat. The most important symptoms of this disease is the appearance of lumps in the breast and change in the shape of the breast external, and the most important risk factors are heredity
Brain cancer Brain cancer is one of the most dangerous cancers in humans. Head disease affects the brain, cerebellum, or spinal cord, and affects the rest of the brain. Headaches, coughs and an increase in visual impairment are the most common symptoms of brain cancer. Brain cancer is the second most common cancer in children, and the number of deaths is estimated to be around 15,000 per year. [6] Skin cancer, liver cancer and prostate cancer are serious cancers Other. In general, the disease is now more dangerous than ever before, especially in light of its early discovery and the functioning of chemical sessions that reduce the incidence of the disease in the body and reduce the symptoms, and may be overcome by many by force and solid will.
