Stage IIIB lung cancer

What does stage IIIB lung cancer mean?

Stage IIIB is a way of writing stage 3B in Latin numerals. Stage 3B lung cancer can mean a number of different things. It can mean that the cancer has spread into lymph nodes on the opposite side of the chest from the affected lung. Or it can mean that the cancer is in the lymph nodes at the centre of the chest (mediastinum) and has spread into one or more of the following areas

  • The chest wall
  • The muscle under the lung (diaphragm)
  • The layers that cover the heart (mediastinal pleura and parietal pericardium)
  • A major structure in your chest such as the heart, the wind pipe (trachea), the food pipe (oesophagus) or a main blood vessel

We have a whole section about lung cancer. This includes detailed information about the stages of lung cancer, treatments for each stage of lung cancer, and about advanced lung cancer.
