Secondary liver cancer

My wife has metastisized breast cancer which went to the bone and now more than likely has spread to the liver. We're waiting the results of an MRI and probably a follow on biopsy but our original surgeon took a look at her scans and is certain about it.
She also has e-coli and had a UTI. Is there an outside chance this could be liver spots from the e-coli? If anyone has had that exerience.
If anyone can post any information on successful protocols, it would be a blessing for us.
We understand we're here not one day less than He's planned for us, but with Him we are hopeful.

By His grace and thank-you.
