Cancer Information

Because lung cancer symptoms often do not manifest until the disease is advanced, only 15 percent of cases are detected in its early stages. Many lung cancer cases are diagnosed in early stage by accident, which means that are detected as a result of medical tests carried out due to other unrelated health problem.

A lung biopsy was used to confirm or refute a possible diagnosis of cancer as well as provide valuable information to determine the appropriate treatment. If it is eventually detected lung cancer, additional tests are carried out to determine how far the disease has spread, including:

History and physical examination: The medical history is recorded risk factors and symptoms in the patient. The physical examination provides information about signs of lung cancer and other health problems.

Radiological studies: These studies use X-rays, magnetic fields, sound waves or radioactive substances to create images inside the body. Often using multiple imaging studies to detect lung cancer and determine the body part where you have spread. It performs a chest x-ray to see if there is any mass or spot on the lungs.

A computed tomography (CT): Gives more detailed information about the size, shape and position of a tumor and can help detect enlarged lymph nodes that may contain a cancer from the lung. CT scans are more sensitive than routine chest radiographs for detecting early-stage cancers.
