My husband was dx june 2010 with stage 4 nsclc. No spread to brain liver or any other vital organ but multiple lymph node involvment. He did have 2 1/2 liters of fluid removed at dx a year ago and talc was used then.  My question is now he has began to have lower leg pitting edema. I requested doplar to rule out blood clots and that came back negative. What could be the cause of the edema and is CHF a concern if the fluid is present in lower extremities?
Hello, Edema in the legs can be due to CHS (heart failure), Renal failure, Thyroid issue, anemia, decreased albumin, any injury. Since you didn't mention the age, it can also contribute dependent edema. Since its pitting edema, we don't need to think of filial disease. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor. R. Raveen
