Risk factorsBy Mayo Clinic staff
Sweet's syndrome is uncommon, but certain factors increase your risk, including:
- Your sex. Women are more likely to have Sweet's syndrome than men.
- Your age. Though older adults and even infants can develop Sweet's syndrome, the condition mainly affects women between the ages of 30 and 50.
- Cancer. Sweet's syndrome is sometimes associated with cancer, most often leukemia. A few cases may be associated with a solid tumor, such as breast or colon cancer.
- Other health problems. Sweet's syndrome often follows an upper respiratory infection, and many people report having flu-like symptoms before the rash appears. Sweet's syndrome can also be associated with inflammatory bowel disease.
- Pregnancy. Some women develop Sweet's syndrome during pregnancy. In these cases, the condition usually clears without treatment.
