Hi thank for contacting HCM.... Here as you have taken chemotherapy it can lead drug induce liver affection ... So enzyme level can be high.... Fruits more with green leafy vegetables taken for it.... Avoid alcohol if habit.... Non veg , refined foods kept minimum... Second here leg edema can be by lymphengitis or lymphatic blockage like case as you have cancer and taking chemotherapy.... Kidney problems and heart failure like case also can lead edema.... Renal function test , ECG helpful for rule it out...... If needed diuretic can be given... Low salt diet taken.... Take care.... Consult gastroentetologist for proper examination .....and subsequent investigation... Dr.Parth
