My tumor was considered small. But until you have your mass biopsied, you will not know the exact kind of tumor that it is. It could be benign. I hope you are scheduled for a consultation soon and that your dr recommends a biopsy. You and your doctor need to know what you are working with before drastic measures are taken like removing your kidney. BTW…my first urologist wanted to remove my kidney. I got a second opinion and I’m glad I did. I also consulted a nephrologist who agreed with my second opinion dr to take a less aggressive, but still effective approach to my cancer. Please be an advocate for yourself and ask your dr questions. You DESERVE answers before any major decisions concerning your health are made. I know this is scary for you, so try to stay calm and focused. Get a legal pad and start compiling a list of questions for your doctor. I’m here if you want to “talk”.
