During World War II, she was part of the Gray Ranks, which led to her being awarded the Cross of Valour for her efforts. After World War II, she attended Gdańsk Medical University, and graduated from there in 1952 with a focus in internal and occupational diseases. After spending a decade in hospitals, in 1962 Krzyżanowska became head of the Provincial Industrial Hospital in Gdańsk, and remained in that role until 1989.
