Breast fibroma, if left untreated, may cause the breast fibroma mass to increase in size, and there is also a risk of malignant transformation into breast cancer. Breast fibroma should be breast fibroadenoma, the disease is a common benign tumor of the breast in women, which may be caused by the abnormal increase in sensitivity of fibroblasts to estrogen in the lobules of the mammary glands, and is prevalent in young women, and is associated with an imbalance in the level of sex hormones in the patient’s body. Mild breast fibroids are benign lesions that grow slowly and do not cause significant discomfort in the early stages of treatment, but can lead to an increase in the size of the breast fibroid mass over time. Breast fibroids have a complete envelope and generally do not metastasize or spread, but the chances of them turning into breast cancer if left untreated are elevated. If patients find fibroid tumors in their breasts, it is recommended that they seek medical attention to check the severity of the condition. Under the guidance of the doctor, take the appropriate treatment program to avoid delaying the condition.
