Micro calcification - Definition

Ask a question


Micro calcification is an accumulation of calcium in organic tissue, such as breast cancer in women: this is called micro calcification of the breast. A micro calcification cannot generally be detected during an X-ray examination as calcifications are invisible to X-rays. The causes of micro calcification are numerous and often benign, micro calcification also often disappear by themselves. Its development, however, must be closely monitored because, in some cases, micro calcification can reveal the presence of cancer.
