. 83 yo mother had a kidney removed 5 yrs ago due to clear cell kidney cancer. In 4-13 she suffered a bad fall. while in hospital getting xrays dr found several large masses in both lungs. Dr says no need for further testing as her body and health is too fragile for treatment . Called hospice and told us about 6 mos . It has now been 5 mos and other than extreme fatigue I am seeing no other symptoms. Is rcc that has mets to the lungs small or non small cancer ? It is very hard not to know what is going on.
