Breast cancer screening is a set of checks that look for cancer before it causes symptoms, when it is smallest and easiest to treat. The right plan depends on your age, your family history, and what your own breast tissue looks like on imaging. Here is how screening changes by decade in 2026, and how to lower your risk at every age.
Breast Self-Awareness in Your 20s and 30s
The most useful habit in your 20s and 30s is simply knowing your own breasts. Breasts change with your cycle, pregnancy, and age, so a lump or thickening that is new for you matters more than any “normal” shape. A monthly self-check a few days after your period helps, but the goal is familiarity, not perfect technique.
Your annual well-woman visit at Bloom OB/GYN includes a clinical breast exam and is the right time to talk through your family history, so we can decide whether you need earlier or extra imaging.
When Should I See a Doctor About a Breast Change?
Do not wait for your next annual visit if you notice any of the following:
- A new lump or a firm area that does not go away after your period
- Nipple discharge that is bloody or happens on its own
- Skin dimpling, redness, or a nipple that has newly turned inward
Most breast changes in younger women turn out to be cysts or hormone-related swelling, but every new change deserves a look. Your OB/GYN can examine you, order an ultrasound or mammogram, and refer you to a breast specialist if needed.
When to Get a Mammogram in Your 40s
If you are at average risk, plan to start regular mammograms at age 40. Current guidance supports screening every year or every other year from 40 onward. Yearly screening is a reasonable choice in your 40s, when breast tissue tends to be denser. Talk with your provider about which interval fits you.
Your OB/GYN does not perform the mammogram itself. We order it, review the results with you, and coordinate any follow-up imaging. Most women receive a 3D mammogram today, which makes it easier to see through overlapping tissue.
Screening in Your 50s, 60s, and Beyond
Screening stays on the same rhythm through your 50s and 60s, and as long as you are in good health, mammograms should continue into your 70s. After that, the decision becomes more individual and is worth revisiting with your provider each year.
What Does It Mean When Your Breasts Are Dense?
Breast density describes how much fibrous and glandular tissue you have compared with fatty tissue. It has nothing to do with size or firmness, and you cannot feel it. It is only seen on a mammogram, and your mammogram report will now tell you which category you fall into.
Dense tissue is common, especially before menopause. It matters for two reasons: dense tissue and cancer both appear white on a mammogram, so a small tumor is easier to miss, and very dense breasts modestly raise your risk on their own. If your report says you have dense breasts, ask whether adding a breast ultrasound or MRI to your mammogram makes sense for you. Density can shift as you age or go through menopause, which is one more reason to keep screening on schedule.
Genetic Testing if Breast or Ovarian Cancer Runs in Your Family
Breast or ovarian cancer in a mother, sister, or daughter, or in a relative diagnosed before age 50, may mean you carry an inherited gene change such as BRCA1 or BRCA2. Bloom OB/GYN offers genetic testing for hereditary cancers right in the office. Testing is a simple blood or saliva sample. Women who carry a high-risk gene often start screening in their 20s or 30s and add yearly breast MRI to their mammograms.
How to Reduce Your Risk of Breast Cancer at Any Age
Age and genetics are out of your hands. Several other risk factors are not:
- Limit alcohol, since even moderate drinking raises breast cancer risk
- Stay physically active and keep a healthy weight, especially after menopause
- Breastfeed if you are able, as longer total breastfeeding time lowers risk
- Use combined menopausal hormone therapy at the lowest dose and for the shortest time that controls your symptoms, and review it each year
