The menstrual period is a time when female hormone levels fluctuate, which is the fundamental reason why most women experience breast pain during menstruation. Due to the fluctuation of hormone levels, there is an increase in breast tissue and edema in the interstitial tissue of the breast, ultimately causing the sensation of breast pain. If the breast pain during menstruation does not ease after the period, or if the pain is very severe, or even painful to touch, attention is needed. This is considered pathological breast pain, likely caused by breast disease, and could be related to breast hyperplasia, mastitis, or even breast tumors. It is necessary to consult a professional doctor for a breast diagnosis.

Can pregnancy cause breast pain?

Pregnant women are very likely to experience breast pain, which is one of the earliest signs of pregnancy. Symptoms like breast tenderness, sensitivity, and a stinging sensation usually appear within 3-4 weeks of pregnancy, sometimes even before a pregnancy test can be taken. This is primarily because, to better support the growth of the fetus, the body produces more estrogen, stimulating the growth of mammary glands and causing breast pain. Of course, as the pregnancy progresses and hormone levels gradually stabilize, breast pain will be alleviated. Pregnant women should not be overly concerned. However, it is also important to remind pregnant women that while this breast pain might increase discomfort during pregnancy, it is usually bearable. If the breast pain becomes unbearable, it is still essential to visit a hospital for a check-up.

Is bilateral breast pain breast cancer?

Bilateral breast pain generally is not considered breast cancer, but rather breast hyperplasia. Diagnosis can be confirmed through breast ultrasound and mammography. The ultrasound of breast hyperplasia typically shows uneven low echo areas; if cysts are present, they appear as anechoic areas. Mammography may display a ground-glass or cotton wool-like shadow. However, it is important to be cautious of the possibility that breast hyperplasia and breast cancer may coexist. On one hand, patients with significant hyperplasia should be closely followed up, advised to return to the hospital every two to three months for follow-up examinations. On the other hand, patients with significant proliferative lumps or unclear boundaries in thickened breast areas are recommended to undergo a biopsy of the suspicious lesions to prevent misdiagnosis.

Will having sex with breast pain lead to pregnancy?

Women may experience breast tenderness before and after menstruation, or during ovulation. However, merely relying on breast tenderness to determine the likelihood of pregnancy during intercourse has no scientific basis. One should consider their menstrual cycle to see if it coincides with the ovulation period, which is typically about 14 days before the onset of the next menstrual cycle. The ovulation date, the five days before it, the four days after it, plus the day of ovulation itself, make up a total of ten days known as the ovulation period. Intercourse during this time is more likely to lead to pregnancy.

What is the cause of postmenopausal breast pain?

Under normal circumstances, if breast swelling and pain occur after menopause, it is necessary to visit a hospital for a breast ultrasound to check for any organic diseases in the breast. If the ultrasound reveals any abnormal masses or conditions, further examination with a mammogram is generally required. Normally, there should not be any swelling or pain in the breasts after menopause. If such symptoms occur, they should be taken seriously, and a hospital visit is necessary for relevant examinations to rule out malignant breast tumors. If there is no malignant tumor and the breast ultrasound does not show significant issues, merely presenting with breast swelling and pain, at this point, some medicinal treatment for regulation can be taken. Traditional Chinese medicine generally considers that the liver meridian passes through the breast, and patients with liver Qi stagnation may experience breast swelling and pain. In such cases, taking medicine to soothe the liver and alleviate depression can be symptomatically appropriate.

Breast swelling, pain, and lumps, what is going on?

There are several types of conditions where lumps can be found in the breast. Breast tissue itself is essentially a hard substance that can normally be grasped or pinched by hand. Therefore, sometimes the lumps you feel in the breast are just normal areas of breast tissue protrusion, which generally disappear after menstruation or after subsiding. You do not need to worry too much about breast lumps that appear during this special period. Another more common type of breast lump is fibroadenoma of the breast, which typically occurs in women of childbearing age between 20 and 39 years old. Another condition is cystic hyperplasia of the breast. This is more common in middle-aged women, often with several hard nodules of varying sizes on both breasts, with unclear borders, which can cause pain, especially more noticeable before menstruation. When it might be a breast disease, it is advisable for patients to visit a hospital and consult a doctor on how to proceed.
