Cancer symptoms: The sound of your voice could predict lung cancer diagnosis

Stage 2 lung cancer

While the cancer can be different sizes at this stage, it may have spread to:

  • Other parts of the lung
  • Areas just outside of the lung
  • Nearby lymph nodes.

Stage 3 lung cancer

This is when the cancer has usually spread to the lymph nodes, and might be growing in the airways, areas surrounding the lung, or other parts of the lung.

Stage 4 lung cancer

Again, the cancer can be any size at stage 4 lung cancer, but it’s possible it could have spread to the lung on the other side.

Moreover, in stage 4 lung cancer, there might be cancer cells in fluid in the pleura, or around the heart.
