Cancer is a somatic cell genetic disorder. Cancer genetics aims to identify people and families who are more likely to acquire cancer as a result of inherited gene mutations.
The whole set of genetic information required for the development and maintenance of life is referred to as a genome. Every organism's genetic information is stored in chromosomes, which are DNA molecules. Simply described, the genome is the sum of all the genes in an organism. Comparative genomics is a rapidly growing field of biology in which scientists compare the genomes of various organisms. Despite the fact that early gene sequencing research was exceedingly expensive and time-consuming, genome sequencing technology has gotten less expensive, labour-intensive, and more powerful. Oncology and cancer research are among the disciplines where comparative genomics is now being used. The interdisciplinary collaboration of researchers in comparative genomics and oncology (also known as comparative cancer genomics or comparative oncology) allows for the examination of inherited cancer risk and tumour development across species, with the ultimate goal of improving cancer care for both human and animal patients.
