Lung cancer

hi everyone. My mom has been told today that she has 'lesions' on her lung, liver and in the lymph nodes in her chest. She will be having further tests over the next few days, I think a bronchoscopy (?) and MRI scan. Has anyone else been told they have the similar symptoms? What treatment could she possibly have? Thank you for your help. 

P.S I did post last night on a different section, her symptoms seemed to point towards stomach cancer but apparently her gastric bits are ok
