There are several terms which describe the type of therapy a patient can receive.
Neoadjuvant, also known as induction therapy, describes therapy which is given before a main treatment, usually surgery, to reduce the tumour.
Adjuvant therapy, is given in addition to the main therapy to prevent recurrence.
Curative treatment aims to destroy the cancer, and palliative treatment aims to relieve symptoms and pain.
When forecasting, recurrence is often grouped with relapsed, to refer to the return of the cancer after a period of improvement or during a time in which the cancer could not be detected. These can be further defined based on where the tumour is located upon relapse, known as local recurrence or regional recurrence.
