A breast showing a coarse light spot light spot may be the result of a patient having a breast ultrasound or mammogram with a substantial object in the breast, generally referred to as a calcified foci. Calcified foci are usually mostly the manifestation of benign lesions, formed by the deposition of calcium salts in local tissues. Calcified foci are the appearance of bone where there is no bone, for example, in the lining of some soft tissues or blood vessels, which are prone to calcified foci, mainly due to inflammation or bleeding for a long time after the gradual deposition of calcium salts in it, which will appear as calcified foci. Benign calcifications are controllable and dispersed, the particles are large in shape, few but widely distributed, and mostly round in shape, which is clinically known as gross calcification. Malignant calcifications are numerous, and groups of tiny calcifications, such as clusters of mud- and sand-like calcifications and pinpoint calcifications, vary in size, thickness, and polarity. Patients with calcified foci should go to the hospital for a detailed examination to clarify the cause of the disease and target treatment.
