Recently, many patients are always worried about whether their breast lumps are malignant tumors. If the physician tells her that malignancy is unlikely, and after confirming the diagnosis of the need for surgical biopsy, she likes to dwell on the problem that the lumps are prone to recur after excision, and it would be better if the lumps were not excised. In response to this phenomenon, the following explanation is made here, hoping that it can help to crack the knot. This misunderstanding is mainly caused by the lack of understanding of breast fibroids and other diseases. How do fibroids occur? The exact pathogenesis is not clear. However, it is related to the following factors: 1. Imbalance of sex hormone level, such as relative or absolute increase of estrogen level, excessive stimulation of estrogen leads to abnormal proliferation of epithelial and mesenchymal components of breast ducts and formation of tumor. 2.Local breast tissue is over-sensitive to estrogen – this category is useless by drawing blood to check estrogen level. 3.High fat and high sugar diet. 4.Heredity. Fibroids are potentially cancerous, but the cancer rate has been reported as varying, ranging from 5% to 15%. So far, there is no report that drugs can cure fibroma. Therefore, it is considered that drug treatment is ineffective, not to mention the so-called “interventional therapy” – injection of drugs (many drugs, such as anhydrous alcohol, etc.) into the lump through various puncture means, otherwise it will induce or aggravate the condition, which can not be cured in reality. Because of the above reasons, therefore, when fibroids are considered by specialist physicians through physical examination and ultrasound, etc., surgical removal is always recommended. As long as these fibroids are completely removed by surgery, there is no question of recurrence of the fibroids, and it is important to eliminate the possibility of cancerous transformation of the fibroids. However, it cannot be ruled out that tiny or latent fibroids may still be present in the same or opposite breast, or that they may be heterochronous (not co-existing). In other words, if you don’t remove the fibroid or other lump that is already there, the fibroid or other tumor that is supposed to grow and reappear will still reappear when it is time to do so. You can’t just keep skipping meals and starving to death because you’re afraid of choking yourself on your food! The same is true for fibroid tumors in the body, who dares to say that they haven’t choked when eating or eating anything else in their life? But is it because of the fear or already choked, and do not eat or no longer eat? The reasoning is clear, and the same is true for benign diseases such as breast fibroids. Therefore, those that have already appeared have to be operated on, and those that will reappear in the future will indeed still have to be operated on. At least, that’s the way it has to be for now. Clinically, there do exist in the breast for decades and did not become cancerous, but this need to take the risk of cancer, so do not advocate conservative treatment. Surgery should be performed instead.
