X-chromosome genetics and human cancer

In mammals, the X chromosome is unique within the chromosome set. In contrast to the other chromosomes - for which two active copies are present - both male and female cells carry only one active X chromosome. This is because males have only one X chromosome and in females only one copy is active, a situation that leads to specific characteristics for genes located on this chromosome. How are the outcomes of genetic events involved in cancer - namely activation of oncogenes and inactivation of tumour suppressors - expected to be different when these genes are carried on the X chromosome rather than on autosomes?
