Tests and scans are used to help doctors find out what type of cancer you may have. It is important for them to know this because different cancer types can behave and respond to treatment differently.
It is possible to diagnose many cancers early. Different treatments are now available for people who are diagnosed with cancer. Even if it is not possible to cure the cancer, treatment can sometimes help control it for months or years.
Cancers are described by:
- site – the area of the body where the cancer first started (the primary site)
- cell type – the type of cell the cancer started from.
