About Dr Yaroslav Mayorchak

I was born 24/10/79 in Lviv (Western Ukraine). When I was 4 years of age my father's father (Principal of School never a smoker) was diagnosed with large right upper lobe lung cancer growing into the right atrium and SVC, upper 3 ribs.  He was deemed inoperable and terminal (3 weeks to live) in Lviv (our region). However, my father pulled all the resources together and took Grandpa to Moscow for salvage radio therapy and salvage mega surgery that followed. The operation involved resection of right upper lobe, right upper chest wall, SVC resection with grafting, resection of pericardial sac and upper part of the heart (15 hours). My grandfather died 16 years later from the heart attack. I was 4 years old when I knew I would be dealing with lung cancer for the rest of my life. Graduated from high school at 15 years of age (with golden medal) after skipping forward few times due to academic merit. Arrived in Australia in 1995 for family reunion with maternal grandmother. Did HSC equivalent at UFS (UNSW), enrolled into MBBS degree at (UNSW).
