metastaszed to lung

Got he news 10/29/2014 after all the scans biopsies, etc.  Treatment is going to chemo.  Don't know what to expect.  If anyone has been through this, I'd like to hear from them.  Also, I'd like to know about survival rates.  Mine is stage four.  And lastly, what is the end like?  pneumonia? or what?

 

Would appreciate any info I can get.
