Besides "diagnosis cancer" already displayed on OCF's book list (it really is excellent); I found "Informed Decisions" published by the ACS extremely useful. In addition to covering ALL possible aspects of cancer, the book also provides an overview of specific types of the disease (e.g. head & neck cancer: larynx, oral cavity, salivary gland). It is very well written and highly informative. I am currently reading several books on oral cancer and will keep you updated on their usefulness.
