Who oversees your care?

[7andcounting]

Is it normal for me to have to try to figure out what my treatment options are? My onc will direct me on drug options, but who looks at the big picture and guides me in seeking other options like Gammaknife or radio ablation for my lung tumors?

Sometimes it seems like a lonely road trying to figure out what my next step is. I feel so burdened down by all the decisions I am constantly making regarding my care.

Thanks for any input.
