What Is Non-Small Cell Lung Cancer

Non-small cell lung cancer, also known as NSCLC, is defined as a cluster or group of different cancers of the lungs that get their name based on the types of cells that are discovered in the cancer and how those cells appear beneath a microscope. This is the most common variety of lung cancer.

More than 75% of individuals who develop lung cancer have one variety or another of NSCLC. This type of cancer is subsequently divided into different subtypes based on the type of cancer cells that are found.

Squamous cell carcinoma

It is the subtype of cancer that develops when cells located in the airway grow too fast and quickly become out of control. This in turn leads to malignant tumors forming in the lungs causing serious damage. Because this area has a regular movement of fluids such as blood, it can often spread to other parts of the body.

Large cell carcinoma

It can form in any part of the lungs. The tumors that result from this do not have the general make-up of other cancerous cells therefore it is different to other subtypes of NSCLC. Large cell carcinoma also grows and spreads faster than of the other subtypes of NSCLC.

Adenocarcinoma

It happens when the cells that make mucus in the lungs begin to grow too fast and result in the development of a tumor. In most cases this subtype of NSCLC stays in one general area.

Because smoking is thought to be the cause of most cases of non-small cell lung cancer cases, it is suggested that smokers are at a much higher risk of developing this disease over individuals who do not smoke. Heavy smokers are said to be at an even greater risk of developing this disease. Smoking however is not the only risk factor to consider in the issue of NSCLC. Some other factors include asbestos exposure, fatigue and defective genes that may be passed down by parents or grandparents. Radon, which is a gas containing radioactive vapors is also thought to be a risk factor, so if you endure exposure to this and you smoke your risk may be significantly higher than a person who is only exposed to one or the other.

Because symptoms of this disease are usually manifested in direct relation to the lungs, it is believed by many that persistent cough, difficulty breathing and pain in the chest may be signs of NSCLC. If an individual experiences these symptoms they should see a doctor so tests can be done to confirm this and begin treatments.

There are four basic tests that can be used to confirm the onset of NSCLC. These tests include physical examination, chest x-ray, CT or computerised tomography scan and bronchoscopy.

Non-small cell lung cancer is one of the most common varieties of lung cancer with thousands of people developing it every year. Early detection of NSCLC is vital to the treatment of this condition. The earlier it is detected the more successful the treatments will be.
