Question:

Date of Diagnosis--Sarcoma: Should the date of diagnosis be coded to the date of biopsy or the date of birth for an infant biopsied at 3 days of age and stated to have a diagnosis of congenital alveolar rhabdomyosarcoma, widely metastatic?

Discussion:

Answer:

Code the date of the biopsy as the date of diagnosis. This is the date the cancer was first identified by a medical practitioner.

Note: SEER collects the Month and Year of diagnosis. The "day" of diagnosis is not collected by SEER.
