mets question?

[Alice]

I had a abdominal ct last week because of pain in left pelvic region. It showed a 1 cm lesion in the liver which I know could be anything including a cyst. It cought the lower part of the lungs where it showed multiple 5 mm densities in the periferal lower lung lobes of both lungs. Does anyone know if this could be a precurser to mets? These tests were ordered by my GP I go to my onc next week and I want to be prepared to ask the right questions. Any suggestions would be helpfull.
Thanks, Alice
