With malignancies affecting the blood or lymph systems or nerve tissues as well as malignancies in the head and neck region that occur as secondary tumours (metastases) from tumours elsewhere in the body all being very different conditions, the timelines and outcomes are different. Treatments of blood malignancies, secondary tumours (metastases), malignancies affecting the lymph system and malignancies of nerve tissues also differ.

Timelines of treatment and outcomes for more common malignancies of the head and neck region are described elsewhere on the website (mouth (oral) cancer, facial skin cancer and cancer of the salivary glands). In addition, a separate section deals with the timelines of treatment and outcomes for malignant bone lesions.
