CancerDue to the proliferation of cancer cells is abnormal. Body of adult human being consists of hundreds of billions of cells. Every minute, billions of these cells die and are replaced by billions of new cells. And reproduce new cells through a process of separation. During this process, the cell divides and two cells are similar. And then double the size of these cells and be able to turn separation. And regenerate normal cells at the same level required to replace the dead cells, while cancer cells proliferate through the separation, but lose the ability to reproduce at a normal rate. May be some non-cancerous tumors or malignant. This type of tumor does not spread to the surrounding healthy tissue or to other parts of the body. The malignant tumors Vngzo the surrounding healthy tissue, and concentrated it, and eventually completely destroyed.
Why is it important to detect the disease early? May destroy malignant tumors cells, carries the blood or Allinv these cells to other parts of the body where it continues to multiply and form tumors. This process is called “metastasis.” The ability of these cells to control the spread of the disease is extremely difficult.
Types of CancerCancer is classified in two ways:(1) through the primary site of cancer in any part of the body that develops the cancer in its infancy.(2) and by the type of tissue where the cancer appeared for the first time.
(1) classification and according to the location of the disease• the majority of skin cancer, skin cancers grow slowly and spread to other parts of the body, and so is the treatment of these cancers is easier than other types of cancer. Recover about 95% of skin cancers that have been treated.• cancer of the digestive tract is the colon and anus (rectum) are more vulnerable members of the cancer, followed by the esophagus, liver, pancreas and stomach. It should be noted that about 50% of patients who have undergone treatment for cancer of the colon and anus (rectum) live five years or more without the emergence of new disease.
Respiratory affects the throat and lungs. Lung cancer is most common between the two.The rate of death among patients with lung cancer is very high. This disease usually spreads to other parts of the body before it was discovered, and thus survive only 10% of patients with lung cancer.• Breast cancer affects about 100 women for one man. And 75% of breast cancers affect women over the age of forty. The survival rate of women who suffer from this disease are being treated before it spreads beyond the breast is a good long-term. Disease is not due to appear again in about 65-75% of these patients for 10 years or more after treatment.• The reproductive system of the penis most vulnerable to the disease is prostate gland of any nationality. And more than 70% of men who underwent prostate cancer treatment and regain well-being Ieadeh disease after 5 years of treatment. The most common cancers in the reproductive system of women is a cancer that affects the member who carries the child of any of the womb. Most of these cancers are at the cervix. The average survival of patients with cervical cancer to 65% approximately.• Blood – Alantma formative and lymph cancer is known as bone marrow and other organs hematopoietic leukemia.This means that breeding immature blood cells. Members are invited lymph cancer lymph tumor. There are several forms of leukemia and tumors of the lymph.Classified types of leukemia Earbh favorite leukemia and chronic spinal cord of chronic leukemia and lymph serious.The tumor lymph or evaluating the tumor, “Hodgkins” or another type of tumor. It should be noted that the survival rate of leukemia and lymph tumor had increased significantly.• cancer of the urinary system cancers do not spread the rest of the urinary system, such as cancers of the other principal organs. And often affects bladder cancer is more common in men than in women.The latest techniques in the treatment of tumors
