the symptoms of lung cancer –Lung cancer is not just a disease but a group of diseases. All forms of cancer-causing cells in the body to change and grow out of control. Most types of cancer cells form a lump or mass called a tumor. Tumor cells can break off and travel to other parts of the body where they can continue to grow.

This expansion process is called metastasis. If the cancer spreads, it is still searching for the body part where the name originated. For example, if breast cancer spreads to the lungs is still breast cancer, not lung cancer.Another word for cancer is malignant, a cancerous tumor called malignant. But not all tumors are cancer. A tumor, cancer is not so benign. Benign tumors do not grow and spread like cancer does. the symptoms of lung cancer
the symptoms of lung cancer
They are usually not life threatening. A few types of cancer, including blood cancer (leukemia), do not form a tumor. Most cancers are named after the part of the body where the cancer first starts. Lung cancer begins in the lungs. The lungs are two spongy organs in the chest. The right lung has three sections called, cloth. the symptoms of lung cancer
The left lung has two lobes. It is smaller because the heart needs more space on the side of the body. The lungs bring air in and out of the body, while oxygen and get rid of carbon dioxide, a waste product. The lining of the lungs called the pleura, helps protect the lungs and allows them to move during breathing.The windpipe (trachea) brings air to the lungs. It divides into tubes called bronchi, which divide into smaller branches called bronchioles. At the end of these small branches are tiny air sacs called alveoli. Most lung cancers start in the lining of the bronchi, but can also begin in other areas such as the trachea, bronchi or alveoli. the symptoms of lung cancer
Lung cancer takes years to develop. Once cancer occurs, cancer cells can break away and spread to other parts of the body. Lung cancer is a serious disease because it often spreads in this way, before he is found. Is the leading cause of cancer death in men and women.
During 2000, approximately 164 100 new cases of lung cancer in this country will be. Around 156 900 people will die of the disease: about 89 300 men and 67 women 600. More people die of lung cancer, colon cancer together breast and prostate. the symptoms of lung cancer
Lung cancer is relatively rare in people under 40 years. The average age of people found to have cancer of the lung, 60 If the cancer is detected and treated early before the surgery that has spread to lymph nodes or other organs, the survival rate of around five years 42%. However, few lung cancers are found at this early stage. Combined, the five-year survival rate for all stages of lung cancer by 14% in 1995, the latest year for which we are the national data.
A risk factor is something that increases a person’s likelihood of disease. Some risk factors such as smoking can be controlled. Others, such as the age of a person can not changed.Smoking is by far the biggest risk factor for lung cancer. More than 8 out of 10 lung cancers diagnosed are thought to lead to the consumption of snuff. the symptoms of lung cancer
The longer a person has been smoking, and the more packs per day smoked, the greater the risk. When a person stops smoking before cancer develops, the lung tissue of normal slow again. Quitting smoking at any age lowers the risk of lung cancer. the symptoms of lung cancer
