Tumorigenesis Research Advances

Tumourigenesis is the formation of tumours in the body, often caused by oncogenes. These tumours are the result of uncontrollable reproduction (cell division) due to alterations in the cell’s genetic code, creating lesions in the tissue where they reside. Tumourigenesis can be divided into tumour initiation, promotion and progression. Oncogenomics often studies tumours caused by such a condition in hope of pinpointing genes – pieces of genetic information – that are susceptible to being changed (mutated) by external factors like ultraviolet light, toxic chemicals, and other carcinogens. The range of normal genetic alterations that a person’s DNA undergoes over time is extraordinarily large, so it is hard to detect exactly what cause tumourigenesis. This book presents the latest research advances in the field.
