[Western Youth Science Popularization] The best time for breast B-ultrasound examination, missed may affect the results

內容目錄

Presumably everyone has done breast ultrasound.

Breast hyperplasia and breast nodules are also common in the examination results.

But you didn’t find it. Every time you go for a review, the size and degree of hyperplasia of the nodules seem to be different.

In fact, this is because breast ultrasound examination will be affected by various factors. Just like gynecological B ultrasound examination, breast ultrasound also has the best time for examination.

If you want to get accurate test results, you must do the test at the most suitable time!

Menstruation is a very magical existence, which periodically makes our endocrine hormones fluctuate, and this fluctuation will cause some changes in our emotions and physiology.

For example, before menstruation, we will feel bad mood, easy to be irritable, cranky, and physiologically, there will be small stomach pain, headache and breast pain.

Especially the breasts, many girls will feel the breasts are swollen and painful about a week before menstruation, and the breast volume will also increase. Larger and lumpy [1].

If you do breast ultrasound at this time, it is likely to prompt the result of breast hyperplasia.

But in reality, these changes gradually return to normal after your period ends. Therefore, the breasts are constantly changing with the menstrual cycle.

Our breast tissue is more sensitive to estrogen and progesterone, and estrogen and progesterone fluctuate greatly before and during menstruation.

At this time, the body’s estrogen secretion gradually increases [2], which will lead to thickening of the breast glands. If you touch it with your hands, you will feel nodules, which are actually thickened glands.

If we choose this time to perform routine breast screening B-ultrasound[3], the lesions or abnormalities are easily concealed by dense breast tissue, so this is not a good time for examination .

The breast anatomy from the skin surface to the chest wall can be clearly displayed only when a breast ultrasound is performed at the right time [4].

Ultrasound image of a normal breast, showing breast anatomy [4]

But when there is already a clinical mass or the doctor suspects an abnormality , In fact, it is not necessary to wait until after menstruation to check, so as not to delay diagnosis.

The optimal time for examination is related to women’s menopausal status:

Non-menopausal women

The best time for breast examination is 3-7 days after menstruation suitable [5].

At this point, estrogen levels in the body drop;

mammary glands degenerate, ducts shrink, and periductal edema resolves;

enlarged breast volume during menstruation It gradually shrinks, the swelling subsides, and the tenderness disappears;

The breasts also become flabby and the glandular nodules shrink or disappear [6].

It can be said that the breast is in a “quiescent state” at this time, and is least affected by estrogen, and it is most likely to find abnormalities or lesions at this time.

Menopausal women

Any time.

Due to the reduction of estrogen in the body, the breast is less affected by hormones, so the examination time can be chosen at will [3].

In short, if you feel breast abnormalities during the menstrual cycle, don’t be afraid, you can go to the hospital for B-ultrasound examination 3-7 days after the menstrual cycle ends, and the most reliable results can often be obtained at this time.
