This phenomenon could result in breakage in the human genome, and when a breakage impacts important genes, such as tumor suppressors, it could lead to cancer development.

In humans, cancer develops when genes that suppress cancer, known as tumor suppressors, are lost and when mutations or genes that promote cancer, known as oncogenes, are gained or activated.

Some examples from their lab include using AAV to introduce epitope tags into the endogenous alleles of the p53 and PTEN tumor suppressor genes in human cells (Kim et al 2008).

Moreover, many human tumors have highly abnormal numbers of chromosomes (that is, they are aneuploid), with initial chromosomal loss participating in the early steps of the transformation cascade in inherited cancers caused by heterozygous mutation in tumor suppressor genes and the more widespread aneuploidy characteristic of advance tumors thought to drive acquisition of malignant growth properties.??
