[|Human|] Hi my mum has stage four bowel cancer which has spread to the liver and to the peretoneum. Operations weren t an option as the cancer has spread too far, she tried chemo back in November but was no point in continuing as the pain and after effects were too horrific. She is doing really good seeing as her oncologist said she should be dead by now, mum feels it is the supplements that are helping to boost her immune system . Her feet have become quite swollen the last few days, is this from the tumours and part of the body breaking down or is it more circulation and she needs to try and move her feet more? thank you
[|AI|]  Hi and welcome to Chat Doctor. I am sorry that you're confronting with such serious disease, but I am glad that your mum feels good. It is always hard to predict every malignant disease. Swollen legs can be caused by tumor pressure on pelvic veins, and this isn't uncommon. But also you should look for heart and kidney disease because both can cause swollen feet. Whatever it is she should lie with elevated leg, can put some pillow underneath and do feet exercise. For the beginning blood pressure and echocardiography and basic labs would be good to evaluate kidney and heart function, although those swelling aren't going to hurt her very much if this isn't extreme. Wish you good health and good luck
