4-Step Non-Small Cell Lung Cancer

Diagnosis

Non-small cell lung cancer occurs when abnormal cells multiply rapidly and do not stop this proliferation. The disease can develop anywhere in the body. Treatment depends on location. It is called lung cancer when it develops in the lungs.

Non-small cell lung cancer (NSCLC) is called lung adenocarcinoma or squamous cell carcinoma. There are three main types of NSCLC: adenocarcinomas, squamous cell carcinomas and large cell carcinomas.

Causes

Several factors increase your risk of developing lung cancer. Smoking or exposure to smoke from others is the main risk factor for the disease. Exposure to asbestos and some dyes or chemicals may also increase your risk.

You may not completely prevent NSCLC. Ask your doctor about ways to help you stop smoking and information about available support groups. Exposure to a radon chemical may increase your risk for the disease. Have your home tested for radon and take the necessary action.

Symptoms

In the early stages, NSCLC usually does not cause any symptoms. When symptoms begin to develop, they may include:
  • long-term cough
  • fatigue
  • chest pain
  • unwanted and unexplained weight loss
  • respiratory problems
  • joint or bone pain
  • weakness
  • cough

Diagnosis

Apart from a physical examination and medical history, various tests may help your doctor diagnose lung cancer. The tests your doctor may want include:
  • Bone Scan
  • Imaging tests such as MRI, CT scan and PET scanning
  • Imaging tests such as MRI, CT scan and PET scanning
  • Microscopic examination of sputum to control cancer cells
  • lung biopsy (removal of a piece of lung tissue for testing)
The cancer staging will be performed after the diagnosis of cancer is confirmed. With grading, doctors classify cancer according to their spread in the body. For NSCLC, there are five stages of increasing intensity between Phase 0 and Stage IV.


Expectancy and treatment depends on the stage. Stage IV disease is typically not fully cured. Treatment at this stage usually aims to reduce symptoms and prepare for death.

Treatment

The treatment of non-small cell lung cancer may vary depending on the stage of your disease, your health and other factors. Talk to your doctor about the best treatment option and possible side effects for you. Different modes can be used to get the best results.

The early stages of NSCLC may be treated by surgery if it is not widely distributed. A lobe or a larger portion of the lung may need to be removed and in some cases the entire lung should be removed.

Chemotherapy uses drugs to kill cancer cells. Oral or intravenous (via a vein). This process leads to the death of the cancer cells within the body by going through the bloodstream of drugs.

Targeted therapies are drugs that target certain aspects of the cancer cell, such as growth factors or blood vessels feeding the tumor. They are often used with more advanced cancers and may not be suitable for everyone.
