lung cancers, primary vs secondary
A few days ago, someone said that my lung cancer data were no good
because many of the deaths included were from cases where lung cancer was
secondary, a metathesis from other cancers. I sent a query about this to
NCHS and received the reply below.

In 2000, there were 155,521 lung cancer underlying cause deaths in the
United States. The information about the cause of these deaths is coded
from the death certificate. If the certifier reported "primary lung cancer"
or "lung cancer," the death is coded as primary lung cancer and this is what
constitutes the number of deaths listed above.
Lung cancer deaths that are coded as secondary lung cancer are not included
in the number of lung cancer underlying cause deaths above. These deaths
are included in a separate code called "Secondary malignant neoplasm of
lung." In 2000, there were 224 underlying cause deaths coded to this cause.
If you have any further questions, please let me know.
