With mouth (oral) cancer, facial skin cancer and cancer of the salivary glands all being very different diseases, timelines and outcomes are described here in separate sections (laryngeal and oro-pharyngeal cancer are not detailed here).

In addition, timelines for malignant bone lesions, malignancies affecting the blood or lymph systems or nerve tissues are described in another section, together with timelines for secondary tumours (metastases) from tumours elsewhere in the body.
