Stage 4 liver cancer substages

Substages 4A or 4B are given for stage 4 liver cancer. Both classifications relate to a single tumor or a collection of lesions of any size, and the treatment choices vary according to the substage:
- Stage 4A: The cancer has spread to nearby lymph nodes but not to distant parts of the body.
- Stage 4B: Cancer may be present in distant organs, such as the lungs or bones.
