Calcification sites are places in the body where calcium salts, or calcium, accumulate. Calcified spots usually occur during bone formation, but can also be abnormally deposited in soft tissues to harden them. Common calcified spots in the human body include calcified spots in the lungs, calcified spots in the breasts, and calcified spots in the liver. Most of the calcified spots are benign, but some of them are symptoms of diseases. Calcified spots in the lungs mostly occur at the apices of the lungs and are usually the result of old tuberculosis and require thorough examination to rule out the presence of new lesions. Calcified spots in the lungs may be the result of varicella pneumonia, cancerous lesions with metastatic properties, etc. Breast calcified spots usually appear as scattered calcifications and can be viewed with radiography. It is recommended that patients present with calcified spots to the hospital to see what is causing them.
