Denis Parsons Burkitt

Denis Parsons Burkitt, MD, FRCS(Ed), FRS (28 February 1911 – 23 March 1993) was an Irish surgeon who made significant advances in health, such as the aetiology of a pediatric cancer, now called Burkitt's lymphoma, and the finding that rates of colorectal cancer are higher in those who eat limited dietary fibre.

Life and death
Burkitt was born in Enniskillen, County Fermanagh, Ireland. He was the son of James Parsons Burkitt, a civil engineer. Aged eleven he lost his right eye in an accident. He attended Portora Royal School in Enniskillen and Dean Close School, England. In 1929 Burkitt entered Trinity College, Dublin to study engineering, but believing his evangelical calling was to be a doctor, he transferred to medicine and graduated in 1935. In 1938 he passed the Royal College of Surgeons of Edinburgh fellowship examinations. On 28 July 1943 he married Olive Rogers.

During World War II, Burkitt served with the Royal Army Medical Corps in England and later in Kenya and Somaliland. After the war, Burkitt decided his future lay in medical service in the developing world and he moved to Uganda. He eventually settled in Kampala and remained there until 1964.

Burkitt was president of the Christian Medical Fellowship and wrote frequently on religious/medical themes. In 1979, he became an honorary fellow of Trinity College Dublin. He received the Bower Award and Prize in 1992. He died of a stroke on 23 March 1993 in Gloucester and was buried in Bisley, Gloucestershire, England.

Scientific contributions
Burkitt made two major contributions to medical science related to his experience in Africa.

Burkitt's lymphoma
The first was the description, distribution, and ultimately, the aetiology of a pediatric cancer that bears his name, Burkitt's lymphoma.

Burkitt in 1957 observed a child with swellings in the angles of the jaw. "About two weeks later ... I looked out the window and saw another child with a swollen face ... and began to investigate these jaw tumours." "Having an intensely enquiring mind, Burkitt took the details of these cases to the records department ... which showed that jaw tumours were common, [and] were often associated with other tumours at unusual sites" in children in Uganda. He kept copious notes and concluded that these apparently different childhood cancers were all manifestations of a single type of malignancy. Burkitt published A sarcoma involving the jaws of African children. The newly identified cancer became known as "Burkitt's lymphoma". He went on to map the geographical distribution of the tumour. Burkitt, together with Dennis Wright, published a book titled Burkitt's Lymphoma in April 1970.

Dietary fibre
His second major contribution came when, on his return to Britain, Burkitt compared the pattern of diseases in African hospitals with Western diseases. He concluded that many Western diseases which were rare in Africa were the result of diet and lifestyle. He wrote a book, Don't Forget Fibre in your Diet, which became an international bestseller.

Burkitt suggested that higher fibre intake can reduce the risk of colorectal cancer. This was based on observations of the difference in patterns of diseases between Western and traditional African societies. Burkitt noted the lower rates of colorectal cancer in African countries compared to the West. He also found that African diets were generally higher in dietary fibre.

Recent research has found that "consuming 10 g more total dietary fibre a day is associated with an average 10% reduction in risk of colorectal cancer" and a diet high in dietary fibre is also advised as a precaution against other diseases such as heart disease and diabetes.
