Elaborate on calcification of collarbone
Patient: I have been diagnosed with a calcification below the collarbone above the 1st rib and will be seeing a Rhuemetologist. What exactly is a calcification? I had rectal cancer in 2001, stage II, lower anterior resection and 6 months chemo. My oncologist is referring me over, should I be concerned, I have discomfort in my chest in that area and have been having low blood pressure with fainting type dizziness. Doctor: Dear patient Calcification is  deposition  of calcium at abnormal sites where normally it is not found for example in lung. You have hot calcification   below clavicle and mostly in lung apex. Since you have been treated  for rectal cancer with chemotherapy  damage to vascular tissue and lung alveoli might have occurred which leads to abnormal  calcification.  Onother possibility  is  calcification  of subclavian artery which lies  just elow clavicle since you are having dizziness and fainting. You need to consult your oncologist  and get I ourself examined. All the best.
