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 as needed. Disruption of the balance system of uncontrolled cell growth and eventually form a mass called a tumor.

Tumors can be benign or malignant; 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 any organ in the body, especially the adrenal glands, liver, brain, and tulang.Kanker 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. While other causes of contamination of the surrounding air by a substance asbestos, air pollution by combustion or fumes including cigarette smoke.

Symptom

Cancer does not show any symptoms are visible from the outside if the cell growth has not been severe. 25% of patients with lung cancer, symptoms are known after they routinely perform chest X-ray or CT scan. If there is proven lung cancer eating dots will seem like a coin ketch.

Symptoms associated with this type of cancer among other respiratory disorders that cause symptoms such as cough, shortness of breath, wheezing, chest pain, and coughing up blood (haemoptysis).

If the cancer has invaded the nerve, 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 blocked, causing an infection (abscess, pneumonia) in the obstructed area.

Symptoms related to metastasis: Lung cancer that has spread to the bone 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 may involve surgical removal of cancer, chemotherapy, or radiation therapy, as well as combinations of these treatments. Decisions about treatment will be feasible for a particular individual should take into account the localization and extent of tumors and overall patient health status.

Like other cancers, may be determined deprivation therapy or cancer or palliative (measures that can not cure cancer but can reduce the pain and suffering of patients.
