Does my oncologist think I have cancer without biopsy proof?

It's completely understandable to feel uncertain about your diagnosis when there hasn't been a biopsy yet. Oncologists often evaluate multiple factors beyond blood work and imaging, but having clear communication about their reasoning and next steps can help ease these concerns. Consider asking your medical team to walk you through their assessment process and what evidence they're basing their recommendations on - you have every right to understand the full picture of your care.
