Understanding breast fibroadenomas and how they develop.

The breast is a secondary sexual characteristic of women and an important organ for lactation, composed of multiple mammary ducts. The breast undergoes cyclical changes in response to hormones, including during puberty, menstruation, pregnancy, and lactation. Recent reports of breast cancer cases have raised awareness among women about breast health, including self-examination, observing breast shape, checking for dimpling, lumps, etc. In fact, most breast problems are benign! Even if a lump is present, it doesn't necessarily mean breast cancer; it could be a benign lump such as a fibroadenoma, cyst, lipoma, or fibrocystic disease. Fibroadenoma, commonly known as a breast fibroadenoma, is the most common. Early-stage fibroadenomas are difficult to detect through self-examination and require a fibroadenoma examination for diagnosis.

What is a fibroadenoma of the breast?

Fibroadenomas of the breast can occur singly or in multiples simultaneously, and can occur in only one breast or both breasts at the same time. Fibroadenomas are mobile, round, firm lumps that are painless. The tumors are usually benign and rarely become malignant. Fibroadenomas are most commonly found in areas of the breast where breast tissue is more developed, namely the upper outer quadrant of both breasts. They can occur in women of any age, but are most common in women of East and African descent aged 15 to 35. Data indicates that approximately 18 to 20% of women have breast fibroadenomas.

Causes and symptoms of breast fibroadenoma

It is generally believed that the formation of breast fibroadenomas is related to the secretion of female hormones. Under the influence of active estrogen, hormonal imbalances promote the proliferation of fibrous or glandular tissue in the breast, resulting in fibroadenomas. However, patients usually do not experience any symptoms. The fibroadenoma contains substantial fibrous and glandular tissue. Some women may feel that the fibroadenoma is round, about the size of a marble, easily movable under the skin, feels firm and elastic, and is not very painful. The edges of the fibroadenoma are also clearly defined. Before menstruation, during pregnancy, or while breastfeeding, patients may feel that the fibroadenoma has significantly enlarged or become painful. Because each breast fibroadenoma grows at a different rate, the size of the fibroadenoma varies. Most breast fibroadenomas remain the same size, some may shrink or even disappear on their own without treatment, while others may continue to grow larger. As women age and their hormone levels decline, breast fibroadenomas may gradually shrink after menopause.

Breast fibroadenomas can be classified into three types: simple fibroadenomas, approximately 1 to 3 centimeters in size; complex fibroadenomas with abnormal changes; and giant fibroadenomas, 5 centimeters or larger in size. Most breast fibroadenomas do not develop into breast cancer or increase the risk of breast cancer; the vast majority of women with breast fibroadenomas can coexist peacefully with them. However, complex fibroadenomas have the characteristic of rapid growth and may increase the risk of breast cancer later in life. As for giant fibroadenomas, their large size can compress other tissues in the breast, thus requiring surgical removal.

Fibromas examination

Clinical examination: The doctor will ask the patient about their symptoms, personal medical history, and family medical history to gather more relevant information. Afterwards, the doctor will perform a physical examination of the breast to assess for any lumps or abnormalities, and will record the size, location, and characteristics in detail.

Imaging examinations: If a doctor finds a lump in a patient's breast after a palpation examination, the doctor will usually arrange for the patient to undergo radiological imaging examinations: breast ultrasound or mammography, in order to further understand the nature of the lump and diagnose whether there are other undetected lesions.

• Breast ultrasound examination: This is a common method for diagnosing breast fibroadenomas. Because breast tissue has varying densities, the three-dimensional images reflected by ultrasound waves can clearly show the characteristics of breast tissue and lumps, including size, shape, and texture, which helps doctors identify the type of breast lump.
• Mammography , also known as a mammogram, is used for women aged 40 and older. Doctors can use the results to determine if a breast lump has calcifications. However, mammography is not the first-line diagnostic method for fibroadenomas; it is more commonly used for breast cancer screening or to assess other breast diseases such as breast cancer.

Pathological examination: If the doctor still has doubts about the nature of the breast lump after imaging examination, he will recommend that the patient undergo fine needle aspiration or core needle biopsy. This involves extracting cell or tissue samples from the breast lump through a needle or surgical procedure to check for the presence of proliferative, atypical, or other malignant cells.

Prevention of breast fibroadenoma

Since the formation of breast fibroadenomas is likely most closely related to female hormone secretion, maintaining hormone levels within the normal range can prevent various breast fibroadenomas and breast lesions. The following six methods can help reduce hormonal imbalances in women:

Sufficient sleep

Maintaining a regular sleep schedule and getting high-quality sleep are crucial for overall health. Studies have shown that the human body needs 8 to 9 hours of sleep in complete darkness to allow the immune system to fully recover and the body to detoxify; going to bed too late or working at night can disrupt hormonal cycles.

Controlling a healthy weight

Obesity has been a major cause of many chronic diseases and cancers. If a large number of fat cells accumulate in the body, it will not only increase the inflammatory response, but also increase the conversion of androgens into estrogens through aromatase, thus greatly increasing the concentration of estrogen in the blood.

Exercise regularly

At least 150 minutes of aerobic exercise per week can not only accelerate the burning of body fat, but also help promote normal hormonal balance and blood circulation (including the breast area), reduce body stress, maintain body metabolism and help eliminate waste, and in the long run, it is beneficial to prevent abnormal cell growth.

Regular women's check-ups

Monthly self-breast exams are an important step in preventing and detecting breast fibroadenomas. They help to detect any abnormalities early, while regular gynecological exams , including clinical and imaging breast examinations by a doctor, can determine the health status of the breasts.

Balanced diet

Foods high in caffeine, sugar, salt, fried foods, and saturated fatty acids can all affect hormone secretion and induce the growth of breast fibroadenomas, so it is advisable to reduce their consumption. Oral contraceptives, breast enhancement pills, and other products containing estrogen may also increase the risk of fibroadenomas; these should not be taken without a doctor's prescription or advice.

Reduce stress

The most common cause of endocrine disorders in women is excessive mental stress and prolonged periods of tension, worry, and anxiety. These negative emotions can disrupt the endocrine system and have adverse effects on the body. It is advisable to learn stress management and maintain a cheerful mood, such as through meditation, deep breathing, and psychological adjustment techniques to reduce stress.
