Question:
Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"?
Discussion:
Answer:
Record the number of tumors counted as a single primary at the time the case is abstracted. Later, if additional tumors are determined to be the same primary, update this field once. Do not update the multiplicity counter more than once.
