Janet Elizabeth Macgregor

She retired to Isle of Seil. She died of cerebrovascular disease on 8 October 2005 at the Lynn of Lorne Nursing Home, Benderloch, near Oban.

Macgregor retired from the University of Aberdeen in 1985. She continued to work part-time as Director of Harris Birthright Research Centre in Aberdeen.

In 1960 Macgregor became a research assistant in Sir Dugald Baird's department of midwifery and gynaecology at the University and worked with his team to establishing a trial screening programme for cervical cancer. Macgregor took exfoliated cell smears using the Papanicolaou stain, interpreted them, and trained the team in the technique. In 1963, she received an MD by thesis for her work. In an article in the British Medical journal co-authored by Macgregor and Baird they stated that cervical cytology has now passed beyond the experimental stage' and that cervical cancer could largely be prevented by cytological detection and treatment of a pre-invasive stage. Having seen the effects of cervical cancer in practice Macgregor took the findings of research and put them into practice, encouraging women to undergo screening. She spoke with general practitioners, convincing them that their patients should be screened. She and the team at the University kept careful records of the screenings, and she collaborated with statisticians to evaluate the effectiveness of screening. Within 5 years of the screen servicing being established there was a significant decrease in cervical cancer in the Aberdeen area. Such was the success of the programme in Aberdeen that it led to cervical screening services being introduced throughout the UK. The research and programme were recognised worldwide, leading to the development of cervical screening all over the world.

After qualifying she served in the Royal Army Medical Corps, rising to the rank of captain. She completed her training at Glasgow Royal Infirmary and Western General Hospital. She worked in Sheffield and Edinburgh before moving to Aberdeen in 1958 with her husband when he took up the position of Regius Professor of Materia medica at the University of Aberdeen.

She met her husband Alastair Goold Macgregor (1919–1972) while they were students at university. They married at University of Glasgow chapel on 3 October 1944, and together they had four children, one daughter and three sons.

She attended school at Bearsden Academy, going on to study medicine at the University of Glasgow during the Second World War, graduating in 1943.
