In general, women are a bit less likely to get cancer than men. But having type 2 diabetes and obesity negates that advantage.
“If you’re a woman with type 2 diabetes, you may be interested in a recent study done regarding obesitiy-related cancer risk. The CDC says that 40 percent of cancers in the U.S. are associated with being overweight or obese. These include cancers of the breast, gallbladder, liver, thyroid, kidneys, uterus, pancreas, upper stomach, colon and rectum, ovaries, multiple myelomas, adenocarcinoma of the esophagus, and meningiomas.
When it comes to diabetes and obesity, the duo “seem to be partly overlapping risk factors for the development of obesity-related cancer”. This especially includes breast, prostate, and colorectal cancer in those with type 2 diabetes, according to study authors.”

Regarding prostate cancer, I’ve seen one study that concluded diabetics are less likely to get prostate cancer.
