The International Classification of Diseases for Oncology (ICD-O) has been used for nearly 25 years as the standard tool for coding diagnoses of neoplasms in tumor and cancer registrars and in pathology laboratories. ICD-O is a dual classification with coding systems for both topography and morphology. The topography code describes the site of origin of the neoplasm and uses the same 3-character and 4-character categories as in the neoplasm section of Chapter II, ICD-10. The morphology code describes the characteristics of the tumor itself, including its cell type and biologic activity.
In preparing this revised edition, the editors have made a special effort to change as few terms as possible, to add new terms at empty spaces, and to avoid reuse of previously assigned codes. While all topography codes remain the same as in the previous edition, morphology codes have been thoroughly reviewed and, where necessary, revised to increase their diagnostic precision and prognostic value.
Customer Reviews, including Product Star Ratings help customers to learn more about the product and decide whether it is the right product for them.
To calculate the overall star rating and percentage breakdown by star, we don’t use a simple average. Instead, our system considers things like how recent a review is and if the reviewer bought the item on Amazon. It also analyzed reviews to verify trustworthiness.
I am using this book for school, it came in excellent condition. The seller answered any questions I had quickly... I will buy from them again, I am very pleased:)
This version is great because it's up to date and thinner. It didn't require a lot of erratas (self-editing of errors from the editors/writers/publishers of the book) which my old book that was given to me had. The older version was falling apart at the binder edge probably due to wear & tear and having to slip pages of paper in between certain pages to keep up with the coding. I would recommend buying this version to save yourself the hassle of updating old erratas.
