Biomarkers can be used for cancer diagnosis and epidemiology. In biomarker, a molecule secreted by a tumor or the biomarkers specific response to the bodily presence of cancer. Bookmarks importance in the development of new drug therapies through the discovery of “druggable targets”. Biomarkers can be specific cells, molecules, or genes, gene products, enzymes, or hormones.
Biological marker generally refers to a measurable indicator of some biological state or condition. The term is also occasionally used to refer to a substance, the presence of which indicates the existence of a living organism.
Biomarker biological molecules can be detected and measured in body parts like tissue and blood. These bio-molecules indicate either diseased processes in the body or normal.
For Example Breast Cancer:
The study of breast cancer remains from the necropolis showed the typical destructive damage, due to metastatic spread. Three tumor marks in breast cancer care I) Cancer Antigen II) Cancer Antigen and III) Carcinoembryonic Antigen: these have been used to helps monitor metastatic breast cancer advanced disease., but they have not been found to be useful to find disease lengthen lives.
In conclusion, the molecular technique of tumor biomarkers says about the disease, there is a no treatment for the physicians describes the similar cases in their practices. The breast cancer is so diverse, complex and is so connected to genetic and environmental factor that finding an impossible to some people.
