Know Your Risk for Breast Cancer

A risk factor is anything that increases your chance of getting a disease, such as cancer. Important risk factors for breast cancer include your age, family history, and sex assigned at birth. Most breast cancers are in women who were assigned female at birth. However, people of all genders can get breast cancer.

Ask your healthcare provider about the risk of getting breast cancer in your lifetime. This is called your lifetime risk. Your lifetime risk determines if you’re at average, intermediate, or high risk for getting breast cancer.

Average Risk for Breast Cancer

You’re at average risk if you were assigned female at birth (your gender now does not matter) and you do not have a history of:

  • A hereditary syndrome, such as a mutation (change or variant) in your BRCA or other genes.
  • Invasive breast cancer or ductal carcinoma in situ (DCIS).
  • Atypical hyperplasia or lobular carcinoma in situ (LCIS). This is a type of breast disease that is not cancer.
  • Dense breasts. A mammogram will show if you have dense breasts.
  • Breast cancer in your family (blood relatives). This is different for everyone. Your healthcare provider will assess your risk.
  • Radiation therapy to your chest when you were young.

Know the Symptoms of Breast Cancer

New lumps, swelling, or redness of your breasts are usually the first symptoms of breast cancer. The best way to find symptoms early is to notice changes in your breasts. Practicing breast self-awareness and doing breast self-exams can help.

Breast self-awareness means being familiar with how your breasts normally look and feel. Everyone should practice breast self-awareness. This way, you can notice any changes in your breasts. Call your healthcare provider if you see any changes, such as a new lump or discharge from your nipple.

A breast self-exam (BSE) is a way to examine your breasts on a regular basis to look for any changes. You can do BSEs once a month, sometimes, or not at all. If you choose not to do a BSE, you should still make sure you know how your breasts normally look and feel.

It’s important not to panic if you see or feel a change in your breast. Most breast changes are not caused by cancer.

Healthy Habits to Lower Your Breast Cancer Risk

Some risk factors like family history and age can’t be changed. But keeping in good overall health can improve your breast health. Here are some tips for staying healthy:  

Get Screened for Breast Cancer

The type of screening you have and your screening schedule are based on your personal risk for breast cancer.

If You’re at Average Risk

  • Starting at age 20, become familiar with how your breasts look and feel. Knowing your breasts will help you notice changes.
  • Get a breast exam from your healthcare provider every year starting at age 25.
  • Starting at age 40, have a mammogram or tomosynthesis (3D mammogram screening) every year.
