Lung Cancer - The Basics
Lung cancer is the most deadly form of cancer men and women. Lung cancer kills more people than colon, prostate, lymph and breast cancer combined. Smoking accounts for nearly 0 percent of cases of lung cancer.
The lungs contain many types of cells. Most of them are epithelial cells lining the airways and produce mucus that lubricates and protects the lungs. Nerve cells, hormone-producing cells, blood cells and structural or support cells are also present in the lungs.
- Researchers found that it takes a series of genetic changes to create a lung cancer cell. Lung cancer begins when cells in the lung grow out of control and form a ball.
- The general types of lung cancer include lung cancer, small cell cancer and non-small cell lung. Small cell lung cancer occurs almost exclusively in heavy smokers. Non-small lung cancer is an umbrella term for several types of lung cancers that behave in a similar way.
- Once a cancerous lung tumor begins to grow, it may or may not eliminate cancer cells. Shed cells can be washed away in the blood or how to float in the natural fluid called lymph tissue that surrounds the lungs. Lymph circulates through the tubes (lymph vessels) that drain into the lymph nodes in the lung, the center of the chest and other body parts.
- commonplace for lung cancer to spread include :. Bone, brain, liver, lymph nodes and adrenal glands
Lung cancer can take years to develop and it causes no signs or symptoms in its early stages. The average age of a person with lung cancer is 69
The signs and symptoms may include shortness of breath, wheezing, hoarseness, chest pain, a new cough that does not go away, the coughing up blood, swelling of the neck / face, fatigue, loss of appetite, repeated problems with pneumonia or bronchitis, and weight loss.
Smoking remains the biggest risk factor for lung cancer. Quitting at any age can significantly reduce the risk of developing lung cancer.
- Exposure to secondhand smoke, radon gas, asbestos, industrial chemicals (arsenic, chromium, nickel, tar soot) radiation and air pollution increases the risk. Test your home for radon.
- People with a parent, sibling or other first-degree relative with lung cancer have an increased risk. .
- Excessive alcohol consumption can increase the risk
