My mum fell sick and was diagnosed with stage IV lung cancer. My world collapsed. Immediately, I started looking online for information about her illness so that I could help her. Unfortunately, my medical knowledge is poor, and the local doctor did not seem professional. Moreover, he mainly talked to my mum, who could no longer interpret the information very well. And so we remained in the dark. After the local doctor was unwilling to meet with me, I started looking for an explanation from another oncologist. He recommended further examinations and a re-diagnosis; however, I could not decide and was unsure if I had understood him correctly. That was when I contacted Diagnose.me. The Diagnose.me oncologist explained the diagnosis and treatment in detail and confirmed that a further examination was necessary. Professor Bartsch’s report helped me to understand the diagnosis better and prepare for further discussion with my mum’s oncologist. I also had some follow-up questions for the professor, which he answered very promptly.
