Ductal Carcinoma in Situ Risk Factors

There are several risk factors associated with ductal carcinoma in situ (DCIS). Their presence doesn’t necessarily mean that a person will develop DCIS; however, people who have one or more risk factors should be especially alert for unusual symptoms and participate in routine screenings. High-risk individuals may need to schedule more frequent screenings than those who do not have any DCIS risk factors; an oncologist can review a patient’s unique situation to determine the most appropriate screening regimen.

The main risk factors for ductal carcinoma in situ include:

  • Having a family history of breast cancer
  • Having a personal history of noncancerous breast conditions (e.g., atypical hyperplasia) 
  • Having genetic mutations associated with breast cancer, such as abnormalities in the BRCA1 and BRCA2 genes
  • Becoming pregnant for the first time after the age of 30
  • Taking estrogen-progestin hormone replacement therapy for more than five years after menopause
  • Having a high body mass index that indicates obesity (excess of body fat in relation to height)

Because ductal carcinoma in situ is considered a risk factor for other, more invasive types of breast cancer, people who have been diagnosed with DCIS need to be especially vigilant about scheduling screenings as recommended by a physician. As is the case with other forms of breast cancer, promptly detecting and treating DCIS is the primary way to obtain the best possible outcome and quality of life.
