"These doctors failed in their duty of care to these women," Mack wrote in her May submission to an inquiry into laws governing termination of pregnancy in Queensland.
The ongoing inquiry was prompted by a bill before the Queensland parliament seeking to remove abortion from the state's criminal code.
One of her patients found out she was pregnant at the same time that she was diagnosed with metastatic ovarian cancer. Her oncologist and gynaecologist would not continue with chemotherapy or surgery "until she was no longer pregnant" but would not provide her with an abortion.
"She was required to discharge herself from hospital and make her way to our clinic independently, her sister pushed her over in a wheelchair," Mack wrote.
