Lung Cancer

Lung cancer is the leading cause of cancer-related deaths worldwide. It occurs when cells divide in the lungs and causes tumors to grow. It affects breathing and may spread to other parts of the body. Lungs are two spongy organs in your chest that take in oxygen when you inhale and release carbon dioxide when you exhale.

The two types of lung cancer are small-cell lung cancer and non-small cell lung cancer. Non-small cell lung cancer is more common than small cell lung cancer.

Stages of Lung Cancer and Survival Rate

The chances of surviving lung cancer can last up to five years or longer upon receiving proper diagnosis and treatment. Stages include:

  1. Localized stage. The cancer cell is in a limited area.
  2. Regional. The cancer cells are spreading in the lymph and other nearby tissues.
  3. Distant. The cancer cell is spreading in other parts of the body.

Stages of Non-small Cell Lung Cancer

  • Occult/ hidden. It is not visible on imaging tests or scans but, they appear on mucus.
  • Stage 0. Abnormal cells start to pop in the top layers of the cells lining the airways.
  • Stage 1. There is a tumor in the lung but, it is 4 centimeters does not spread to other parts of the body.
  • Stage 2. The tumor grows up to 7 centimeters and spreads in nearby tissue.
  • Stage 3. The cancer call spreads to lymph nodes and other surrounding parts of the lung.

  • Sputum
  • Blood
