What causes breast glandular thickening?

Breast hyperplasia does not mean that a breast tumor has appeared, so friends do not need to worry too much in life. However, after breast hyperplasia occurs, necessary treatment must be done, otherwise breast hyperplasia may cause more serious diseases. Like other diseases, breast hyperplasia must have a cause, so what is the cause of breast gland thickening?

Causes

Under the influence of endocrine hormones, especially estrogen and progesterone, the breast will undergo changes in proliferation and involution as the menstrual cycle changes. Due to certain reasons, endocrine hormone metabolism is unbalanced and estrogen levels increase, which can lead to excessive breast tissue proliferation and incomplete restoration. After a period of time, the hyperplastic breast tissue cannot completely disappear, resulting in breast hyperplasia.

examine

1. Breast palpation

Women's breasts are uneven, and many women feel that the lumps they feel are just normal breast bulges. Before each menstrual period, these lumps become more obvious and easier to touch. In terms of the characteristics of breast lumps, fibrocystic breast disease often results in the discovery of multiple nodules of varying sizes and unclear boundaries in both breasts at the same time or successively, which can be moved. Breast fibroadenoma lumps are mostly round or oval, with clear boundaries, smooth surface, no adhesion to the skin and surrounding tissues, large range of motion, and a slippery feeling when touched. Breast cancer lumps are mostly single nodules with irregular edges. Most are hard in texture and often adhere to the skin.

2. Color Doppler Ultrasound

Convenient, non-invasive, and can be repeated many times. Based on the shape, cysticity and solidity of breast nodules and their relationship with surrounding tissues, a differential diagnosis can be made between breast hyperplasia, breast fibroadenoma and breast cancer.

3. Mammography

It has a high diagnostic value and can clearly display the various layers of breast tissue and calcification foci. It has certain advantages in distinguishing benign from malignant lesions and detecting breast cancer at an early stage. However, it has poor imaging for young women and dense breasts (glandular density > 70%).

4. Breast MRI

It can quickly obtain high-precision images of the internal structure of the breast, without ionizing radiation and no adverse effects on the human body. It is more suitable for the examination of multiple small lesions in the breast, lesions located deep in the breast close to the chest wall, and patients with breast prostheses. Therefore, when color ultrasound and mammography show highly suspicious lesions, MRI examination can be further performed.

5. Breast lesion biopsy

In order to rule out malignant lesions, breast nodules can be subjected to lesion puncture examination if necessary. This examination is a invasive examination and is the "gold standard" for diagnosing and excluding breast cancer.
