cal·ci·fi·ca·tion C0027400 (kăl′sə-fĭ-kā′shən)n.1. a. Impregnation with calcium or calcium salts, as with calcium carbonate.b. Hardening, as of tissue, by such impregnation.2. A calcified substance or part.3. An inflexible, unchanging state: calcification of negotiations.calcification (ˌkælsɪfɪˈkeɪʃən) n1. (Biochemistry) the process of calcifying or becoming calcified2. (Geological Science) the process of calcifying or becoming calcified3. (Physiology) pathol a tissue hardened by deposition of lime salts4. (Geological Science) any calcified object or formationcal•ci•fi•ca•tion (ˌkæl sə fɪˈkeɪ ʃən)
n. 1. a changing into lime. 2. the deposition of lime or insoluble salts of calcium and magnesium, as in a tissue. 3. Anat., Geol. a calcified formation. 4. a process in which surface soil is supplied with calcium in such a way that the soil colloids are always close to saturation. 5. a hardening or solidifying. cal·ci·fi·ca·tion (kăl′sə-fĭ-kā′shən)1. Medicine The accumulation of calcium or calcium salts in a body tissue. Calcification normally occurs in the formation of bone.2. Geology a. The replacement of organic material, especially original hard material such as bone, with calcium carbonate during the process of fossilization.b. The accumulation of calcium in certain soils, especially soils of cool temperate regions where leaching takes place very slowly.Thesaurus| Noun | 1. | calcification - a process that impregnates something with calcium (or calcium salts)chemical action, chemical change, chemical process - (chemistry) any process determined by the atomic and molecular composition and structure of the substances involvedossification - the calcification of soft tissue into a bonelike material | | 2. | calcification - tissue hardened by deposition of lime saltshardening - abnormal hardening or thickening of tissue | | 3. | calcification - an inflexible and unchanging state; "the calcification of negotiations"inaction, inactiveness, inactivity - the state of being inactive |

calcification[‚kal·sə·fə′kā·shən] (geochemistry) Any process of soil formation in which the soil colloids are saturated to a high degree with exchangeable calcium, thus rendering them relatively immobile and nearly neutral in reaction. (physiology) The deposit of calcareous matter within the tissues of the body. calcification
calcification [kal″sĭ-fĭ-ka´shun] the deposit of calcium salts, mostly calcium phosphate, in body tissues. The normal absorption of calcium is facilitated by parathyroid hormone and by vitamin D. When there are increased amounts of parathyroid hormone in the blood (as in hyperparathyroidism), there is deposition of calcium in the alveoli of the lungs, the renal tubules, the thyroid gland, the gastric mucosa, and the arterial walls. Normally calcium is deposited in the bone matrix to insure stability and strength of the bone and in growing teeth.dystrophic calcification the deposition of calcium in abnormal tissue, such as scar tissue or atherosclerotic plaques, without abnormalities of blood calcium.eggshell calcification deposition of a thin layer of calcium around a thoracic lymph node, often seen in silicosis.cal·ci·fi·ca·tion (kal'si-fi-kā'shŭn), 1. Deposition of lime or other insoluble calcium salts. 2. A process in which tissue or noncellular material in the body becomes hardened as the result of precipitates or larger deposits of insoluble salts of calcium (and also magnesium), especially calcium carbonate and phosphate (hydroxyapatite) normally occurring only in the formation of bone and teeth. 3. A dense opacity (less dense than metal, however) on a radiographic image. Synonym(s): calcareous infiltration [L. calx, lime, + facio, to make] calcification (kăl′sə-fĭ-kā′shən)n.1. a. Impregnation with calcium or calcium salts, as with calcium carbonate.b. Hardening, as of tissue, by such impregnation.2. A calcified substance or part.calcification The deposition of calcium in tissues; the term mineralisation is often used for physiologic calcification.calcification Medtalk The deposition of calcium in tissuescal·ci·fi·ca·tion (kal'si-fi-kā'shŭn) 1. Deposition of lime or other insoluble calcium salts. 2. A process in which tissue or noncellular material in the body becomes hardened as the result of precipitates or larger deposits of insoluble salts of calcium (and also magnesium), especially calcium carbonate and phosphate (hydroxyapatite), normally occurring only in the formation of bone and teeth.
Synonym(s): calcareous infiltration. [L. calx, lime, + facio, to make]calcification Deposition of calcium salts, usually calcium hydroxyapatite crystals, in body tissues, especially when there has been prolonged inflammation or injury. Calcification is normal in bones and teeth.cal·ci·fi·ca·tion (kal'si-fi-kā'shŭn) 1. Deposition of lime or other insoluble calcium salts. 2. Process in which tissue or noncellular material in the body hardens due to precipitates or larger deposits of insoluble salts of calcium, especially calcium carbonate and phosphate normally occurring only in the formation of bone and teeth. [L. calx, lime, + facio, to make]Patient discussion about calcificationQ. Please let me know what is breast calcification? My mom aged 52 years is diagnosed with breast cancer and is suffering for the past 5 years. I am scared too as I know that possibility of breast cancer is also linked genetically. The mammogram report shows some white spots on mammogram. But it has been recorded as breast calcifications. Doctor advised me not to worry as this has got no relevance to breast cancer. Please let me know what is breast calcification?A. These are tiny calcium deposits in the breast tissue. You can not touch or feel breast calcifications. To know about them the only way is by mammogram. They are usually not cancerous but in some forms like tight clusters with irregular shapes can indicate breast cancer. There are two main types: microcalfications and macrocalfications. But if your doctor says that they pose no threat then I am sure you have nothing to worry about. Just follow his advices.
