Causes and Symptoms of Lung Cancer
Description
Lung cancer, like all cancers, is the result of an abnormal cell, the most basic unit of life. Normally, the body maintain a system of checks and balances on cell growth, so that cells divide to produce new cells are needed. Disruption of the balance system of uncontrolled cell growth and eventually form a mass called a tumor.
Tumors can be benign or malignant, and malignant tumor is called cancer. Benign tumors can usually be removed and not spread to other body parts. Malignant tumors, on the other hand, grow aggressively and invade other body tissues, so that the tumor cells into the bloodstream or lymphatic system and then into the inside of the body. Deployment process is called metastasis.
Since lung cancer tends to spread, or metastasize, then it is very threatening. Lung cancer can spread to every organ in the body, especially the adrenal glands, liver, brain, and bones. This cancer is also one of the most difficult cancers to treat. The lungs are also the organ most frequently affected by tumors in other body parts.
Cause
The main cause of lung cancer is smoking well as active smokers or passive smokers. While other causes of contamination of the surrounding air by the substance of asbestos, air pollution by fumes or combustion including tobacco smoke.
Symptom
Cancer does not show any visible symptoms from the outside if the cell growth has not been severe. As many as 25% of patients with lung cancer, known symptoms after they routinely perform chest X-ray or CT scan. If proven to have lung cancer then it will seem like a coin dots ketch.
Symptoms associated with this type of cancer among other breathing disorder that causes symptoms such as cough, shortness of breath, wheezing, chest pain, and coughing up blood (haemoptysis).
If the cancer has invaded nerves, for example, can cause shoulder pain that moves on the outside of the arm (called Pancoast's syndrome) or vocal cord paralysis causes hoarseness. Invasion of the esophagus can cause difficulty swallowing (dysphagia). If breathing is hampered, leading to infection (abscesses, pneumonia) in the area hampered.
Symptoms related to metastasis: Lung cancer that has spread to the bones may produce excruciating pain in the bones. While the cancer that has spread to the brain can cause a number of neurological symptoms such as blurred vision, headaches, seizures, or stroke symptoms such as weakness or loss of sensation in parts of the body.
Treatment
Treatment for lung cancer can involve surgical removal of cancer, chemotherapy, or radiation therapy, as well as combinations of these treatments. Decisions about treatment will be appropriate for certain individuals must take into account the localization and extent of the tumor and the patient's overall health status.
Like other cancers, may be determined revocation or cancer therapy or palliative (measures which can not cure cancer but can reduce the pain and suffering of patients.
