- How mutations, chromosomal changes epigenetics, and environmental agents play roles in the development of cancer ?arrow_forwardHow can the role of epigenetics in cancer be reconciled with the idea that cancer is caused by the accumulation of genetic mutations in tumor-suppressor genes and proto-oncogenes?arrow_forwardAccording to the multi-hit model, more than one mutation must occur in a cell for cancer to develop. Once an oncogene has been formed by a mutation, what other type of gene must also mutate?arrow_forward
