Fibroid calcification is not necessarily cancer. Breast fibroid is a very common benign breast tumor in young women. Generally, because of its malignant potential, breast fibroid usually needs to be treated by surgery after diagnosis, and conservative treatment is not effective. Once a breast fibroid becomes calcified, it means that the fibroid stimulates the surrounding tissues to proliferate and harden for a long time, so it shows increased density on the imaging, so it is described as a fibroid with calcification, and the stimulation for too long will have the possibility of malignant transformation. However, the exact basis must be removed completely and the malignant tumor cells must be found through pathological examination under the microscope to confirm that it is cancer, so fibroma with calcification is not necessarily cancer.
