Nodules in Liver and Lungs

Hi,

Im new to this group and i write on behalf of my mother in law.

I went with my mother in law to see her consultant last week where i was shown the results of her CT scan. She has multiple nodules on her liver and lungs. 

The next step is a PET scan and blood tests to see if they can locate a tumour.

Has anyone else had this, where it has turned out not to be a tumour? We are so worried that this could be secondary cancer. Praying for a miracle its something else.

Any advice would be great.

Thank you
