How is diabetic mastopathy diagnosed?

The diagnosis of diabetic mastopathy should be considered in patients with long-standing insulin-dependent diabetes and a firm, mobile breast mass. Initial imaging studies may include mammography and ultrasound. While these methods can help to further differentiate the mass, they cannot provide a specific diagnosis of diabetic mastopathy with confident exclusion of malignancy. A core biopsy (utilizing a needle to remove a small cylinder of tissue) is often performed for a definitive diagnosis.

Does diabetic mastopathy increase a person's risk for developing breast cancer?

No. Research shows that diabetic mastopathy does not increase a person's risk for developing breast cancer. The small number of reported cases which describe malignancy in patients with diabetic mastopathy are believed to be due to coincidence. At this time, there is no pathologic literature linking diabetic mastopathy with malignancy.

Is pain in the breast a symptom of breast cancer?

Early breast cancer usually does not cause pain. Still, a person should see his/her health care provider about breast pain or any other symptom that does not go away. Most often, these symptoms are not due to cancer. Other health problems may also cause them. Any person with these symptoms should tell their doctor so that problems can be diagnosed and treated as early as possible.

Can diabetic mastopathy recur?

Yes. Diabetic mastopathy can recur. In patients with recurrence, the recurrence tends to be in the same location involving more breast tissue than previously seen.

How is diabetic mastopathy treated?

Typically, no treatment is necessary for diabetic mastopathy. Individuals with this condition should be advised about the condition and how to self examine the breasts to detect any changes in size and number of breast lumps. Patients should be routinely followed up with MRI or ultrasound and core biopsy if the lesions become clinically or radiologically suspicious. Lesions can be surgically removed for cosmetic reasons or if malignancy cannot be excluded.
