What is molecular oncology exactly ?

Defining genes: In order to understand tumor behavior the molecular biologist looks at viable tumor cells with regard to the DNA, oncogene mutations and the nature of the antigens that are expressed by the tumor. Then how they are chaperoned to the membrane where they are shed as in serum representing tumor markers .Also the various metabolic pathways the tumor follows to allow for growth and spread.

New cancer paradigm: Molecular oncology is looking at the cancer and cancer patients on a molecular level by looking at the gene expression profiling, next generation genome sequencing and molecular alterations rather than the old school method of looking at type of cancer under the microscope by the size, locations and other pathological characteristics
