[|Human|] I was diagnosed with kidney cancer this past spring and had a right radial nephrectomy- patho revealed clear margins. YAY! After my surgery I have been paying attention more to drinking lots of water, protecting the kidneys, signs of kidney failure. My shoes have been feeling tight, in particular, my right shoe. I ve even had to move up a size in shoes. No signs of swelling are present. However, tonight I realized that my right foot is now about 1 inch longer than my left foot!! This has never been like that before. I am 31 years old and have worn the same size shoes with no problems since the 7th grade. What s happening?
[|AI|]  Thanks for your question on Chat Doctor. There are few causes for unilateral (right) sided edema of lower limb in renal cancer patients (post neurectomy).1. Spread of tumor in right lower limb lymphatic s and cause obstruction and edema.2. Renal failure can also cause lower limb edema.3. If you sleep on right side than dependent edema can also occur.4. Hypoprotienemia and anemia can also cause lower limb edema.5. Thrombosis in veins and arteries of right lower limb due to tumor spread can also be the cause. So consult your oncologist and discuss all these.
