There are no known ways to prevent any type of breast cancer, including ductal carcinoma. However, there are tangible ways to reduce the impact of the disease by finding it early. Women are urged to have a breast examination performed by a physician or other healthcare provider every three years until they reach the age of 40. After age 40, women are urged to also schedule a mammogram every year or every other year. This is particularly important because ductal carcinoma in situ (DCIS) is detected only with a mammogram. In addition, all women are advised to conduct periodic breast self-examinations.

Other preventive measures include:

• Limiting alcohol consumption
  
  
• Maintaining a healthy weight
  
  
• Consulting a physician regarding taking estrogen or other hormones
  
  
• Incorporating physical activity into daily life
  
  
• Eating foods high in fiber and low in fat
  
  
• Eating plenty of fruits and vegetables
  
  
• Avoiding exposure to pesticides
  
  
• Avoiding unnecessary antibiotics
  
  
• Not using tobacco products of any kind
