The two genes considered responsible for the cause of cancer are the oncogene and the tumor suppressor gene.
The Cancer Research UK, Genes UK and WebMD sites all offer comprehensive information on the genetic relationships of breast cancer. However to get proper advice one should consult a healthcare professional.

One of the primary possible benefits of the Human Genome Project is major advances in cancer research and treatment. Work is already being done to isolate cancer causing genes.
An oncogene is a gene that may be able to cause cancer. These genes can cause cells to mutate, instead of simply dying, which they are supposed to do.
there is no such thing.
5% of breast cancer is down due to a genetic fault. These genes are passed down through abnormal genes passed from parent to child. An example of this is the BRCA genes.
The two types of cell cycle genes that cause cancer cells to divide uncontrollably if mutated are called tumor suppressor genes and antioncogene
