Different tumour markers may be detected in blood but not always. Here are some basic informations.,

Cancer markers of different systems of body, Gynae markers in particular: _. Tumour marker of female genital Tract like cancers of Cx, Corpus or say F tunes. Let us explore our knowledge on different cancer markers .Tumour marker is a substance present in or produced by a tumour itself or produced by the host in response to a tumour from normal tissue or to determine the presence of a tumour based on measurement in blood or secretions. It is measured qualitatively or quantitatively by chemical immunological or molecular methods to identify cancer presence. Ideally tumour marker should occur only inpatients with malignancy should correlate with stage and response to treatment and should be easily and reproducibly measured. No tumour marker has met this ideal yet. Tumor markers are either polypeptides protein hormones surface antigens cytokines oncogenes or gene products. Baseline levels measured prior to therapeutic intervention and followed later by serial periodic measurements help to predict outcome of therapy.:-Tumour markers also help in early detection of recurrence relapses and metastasis. However it is the rate of change of the tumour marker level which is more important than its absolute vale. These tests should not be used as a screening test but should be correlated with other clinical criteria.

Why Tumour markers & PET scan are getting popular in day to day practice by oncologist??  What are the Clinical Applications of T markers?? - Mass screening, differential diagnosis in symptomatic patient’s clinical staging estimating tumour volume prognostic indicator of disease progression detecting recurrence evaluating the success of treatment and monitoring response to therapy.
