I am stage 4 breast cancer and have been on Avastin for almost 2 years along with a couple of other chemos which they keep shifting. I’ve complained endless times to my oncologist that my urine is foamy but he says that this will disappear once I’m off Avastin. Now I don’t urinate for hours after I drink. When I mentioned this he told me that he will stop Avastin for a couple of months and see. My urea and creatinine levels are still normal. I’m really concerned because my urine is still very foamy even though I’ve had my last Avastin infusion last month. Has anyone been in a similar position?
