Understand how a cancer cell from a primary benign tumor is able to leave the primary benign tumor and enter the blood stream or lymph (migration), start to adhere and grow in a nearby environment like a blood vessel near an organ (invasion) and enter into a new organ to grow and form a secondary tumor ( extravasation). What proteins would be involved in these steps and what molecular changes in the ECM or basal lamina would need to occur as well as the cancer cell for this process to happen

Genomic studies

Genomic studies (genomics) is the study of the whole genome of an organism. Using bioinformatics and high-performance computing, genomic researchers examined massive amounts of deoxyribonucleic acid (DNA)-sequence data to discover variations or mutations that affect drug response, health, or disease. Genomics is a much younger discipline than genetics, having only emerged in the last few decades as a result of technological advancements in DNA sequencing and computational biology.
