Cancer codes

If have a pt with a diagnosis of breast cancer and liver cancer with no specificity of primary or indeterminate, which would I code as primary?

I would find out the primary before I guessed on which to use.

The AHA coding clinic states that when the dc is just say breast cancer then you code as primary. But if the dc is more common as a secondary site as liver cancer then you code it as a secondary with unknown primary.

Thanks much for the info
