Definition: | Laterality describes which side of a paired organ is the origin of the primary cancer. Each side of a paired organ is considered separately and described as lateral when occurring unless a physician determines that it is bilateral. A paired organ is one in which there are two separate organs of the same kind, one on either side of the body (e.g. kidney, breast, ovary, testis and lung). |
Context: | This information is collected for the purpose of differentiating the site of the primary cancer. For example, a woman may present with a primary cancer in the left breast. She may return at a later stage with a new primary cancer in the right breast. |

Guide for use: | Record the appropriate code at the time of diagnosis. Definitions Right: Origin of primary site is on the right side of a paired organ. Left: Origin of primary site is on the left side of a paired organ. Bilateral: Origin of primary site is on both sides of a paired organ. (When tumours of the same morphology are diagnosed simultaneously in both sides of a paired organ.) Includes organs that are bilateral as a single primary (e.g. bilateral retinoblastoma (M9510/3, C69.2), (M9511/3, C69.2), (M9512/3, C69.2), (C69.6, C48.0), bilateral Wilms tumours (C64.9, M8960/3)) Note: Bilateral cancers are very rare. Unknown: It is unknown whether, for a paired organ the origin of the cancer was on the left or right side of the body. Paired organs and structures The valid International Classification of Diseases for Oncology values for paired organs are provided in the list below:

Comments: | The laterality of the primary tumour may have implications for treatment and prognosis, and can be of assistance to cancer registries for the coding of subsequent tumours in paired organs. | ||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
