Scientists at Chang Gung Memorial Hospital and Chang Gung University in Taiwan found a higher-than-average risk of particular cancers in women with a history of Gestational diabetes or pregnancy-related diabetes. Their study was published in February of 2019 in the British Medical Journal.

A total of 47,373 women with Gestational diabetes and 943,199 women with healthy pregnancies were admitted to the study and followed for three years. Women with a history of Gestational diabetes had more than twice the risk of developing cancer as women without such a history. They were…

• more than twice as likely to develop kidney cancer,
• almost 74 percent more likely to develop cancer of the nose or throat,
• over 37 percent more likely to be diagnosed with lung cancer,
• almost 39 percent more likely to develop thyroid gland cancer, and
• over 23 percent more likely to develop breast cancer.

The researchers concluded women who had a history of Gestational diabetes should be screened for the cancers listed above.

Prevention of Gestational diabetes should begin before women conceive. Gestational diabetes starts during pregnancy, especially in women over age 25. Being overweight is a risk factor, therefore, women planning to conceive need to normalize their weight; and during pregnancy, mothers need to gain only the recommended amount of weight. Getting enough physical activity and rest is important too.
