THORAX ABDOMEN AND PELVIS

Detailed explanation-1: -The CA15-3 tumor marker has been widely considered for the prognosis of bone metastases in patients with breast cancer. CA15-3, a high molecular weight glycoprotein (300-450 kDa), is synthesized by apical surface of epithelial ducts and acinic breast cells and is then secreted in milk normally.

Detailed explanation-2: -A CA 15-3 test is a blood test that doctors may use for people with a breast cancer diagnosis and those who have had breast cancer. The CA 15-3 test shows the levels of CA 15-3 protein in the blood, which can increase as breast cancer advances.

Detailed explanation-3: -Cancer antigen 15-3 (CA 15-3) is used to monitor response to breast cancer treatment and disease recurrence. The reference range of serum CA 15-3 is less than 30 U/mL. The upper limit of the range varies depending on the laboratory and kit used for the test.

Detailed explanation-4: -CA 15–3 is a marker with definite diagnostic accuracy compared to CEA and CA 125 in breast cancer EF. CA 125 appears to derive from proliferating mesothelia rather than cancer cells alone and occurs in a broad spectrum of malignant as well as benign EF.
