A young girl is brought in with a seemingly routine stomach ache.
A widowed mother is diagnosed with a massive malignant tumor (leiomyosarcoma) situated between her aorta and left kidney.
Dr. Melendez initially believes the tumor is inoperable, suggesting they simply send her home with three months to live.
Dr. Jared Kalu presents Shaun's idea as his own to Dr. Melendez. The surgery is successful, saving Stephanie's life.
Late at night, Shaun performs an unsanctioned home visit and finds Martine unconscious. He performs CPR in the back of her parents' car while they rush to the hospital.
Shaun suggests a high-risk procedure: removing a perfectly healthy kidney to gain better visibility of the tumor.
She suffers from intestinal malrotation (twisted intestines), requiring immediate surgery that ultimately saves her life. The Good Doctor: Season 1/ Episode 2 "Mount Rushmore"
