Dawson dedicated her career to studying pathology, initially as a cancer research fellow from 1931 at Edinburgh University.
Her thesis on “Sarcoma of the Breast” 1970 was noted to be of ‘outstanding significance.’[2] Dawson later lectured at the Royal College of Surgeons of Edinburgh while also carrying out research at the laboratory.
In 1941, she was appointed as temporary part-time Assistant Histologist to the Laboratory at the Royal College of Physicians of Edinburgh.
In addition, Surgeons’ Hall Museums holds Dawson's histology collection of thousands of slides of a variety of systems.
