Risk factors
By Mayo Clinic staffIn general, the factors that put you at risk of developing DCIS are the same as risk factors for developing invasive breast cancer.
Things that increase your risk of DCIS include:
- Older age
- Personal history of benign breast disease, such as atypical hyperplasia
- Family history of breast cancer
- Never having been pregnant
- First pregnancy after age 30
- Taking combination estrogen-progestin hormone replacement therapy (HRT) for five years or longer after menopause.
- Genetic mutations, such as in the BRCA1 or BRCA2 genes
