From feeling a lump while getting dressed to high-definition images from advanced technology, there are many ways breast cancer can be diagnosed. Here are four screening options and how to determine which one is right for you.
1. Breast self-examination
You may have heard that doing monthly breast self-examinations is recommended to help you find potentially cancerous lumps. But now some organizations recommend not doing self-exams. Why the difference?
Reasons not to do breast self-exams:
- Large research studies involving hundreds of thousands of women around the world have failed to show an improvement in breast cancer survival among women who did monthly self-exams.
- Most lumps felt on self-exams are not cancerous, so women may undergo unnecessary testing and suffer anxiety associated with this.
- Most breast cancers are diagnosed because a women felt a lump during regular daily activities such as bathing or dressing.
Reasons to do breast self-exams:
- Doing regular self-exams will make you more aware of how your breasts normally feel, so you are more likely to notice when there is a change.
- About 40 percent of breast cancers are diagnosed because a woman felt a lump in the breast.
- About 10 percent of breast cancers cannot be seen on a mammogram, even if they are felt.
When to do a breast self-exam:
Talk to your doctor about whether monthly self-exams are right for you—factoring in potential risks, family history and other personal preferences.
If you choose to do self-breast exams, you should do them at the same time of every month.
- For pre-menopausal women, this should be several days after each period ends.
- For post-menopausal women, picking a certain day of the month and doing it that same day every month is helpful.
Step-by-step instructions for how to do breast self-exams are available at breastcancer.org.
A mammogram is a low-dose X-ray of the breast. This is the most widely recommended screening test for women.
Some mammograms include 3D technology, called breast tomosynthesis, where multiple images of the breast can be compiled to pinpoint the size, shape and location of abnormalities.
Who should get a mammogram?
- Sanford Health recommends annual mammograms starting at age 40.
- Your doctor may recommend screening earlier depending on your personal risk.
- Regular mammograms should continue for as long as you are in good health.
3. Breast MRI
A breast MRI should not be used in place of an annual mammogram screening but rather in addition to it, if recommended.
4. Whole breast ultrasound or automated breast ultrasound system (ABUS)
Breast ultrasounds are not routinely done as a breast cancer screening. This option is typically only recommended for people who are unable to complete an MRI or who have certain syndromes, such as Li-Fraumini.
When you should see a doctor for a breast concern
In general, you should contact your doctor or provider anytime you notice something different about your breast, such as:
- Nipple discharge (especially bloody or clear)
- Swelling of one breast
- Change in the shape of the breast
- Dimpling of the skin
- New pain in one spot that doesn’t go away
Talk to your doctor about your family history, your concerns and the best screening options for you.
