Although there tends to be great molecular diversity in each person's cancer, there are still avenues of genetic commonality that can be pursued. For example,

Although there tends to be great molecular diversity in each person's cancer, there are still avenues of genetic commonality that can be pursued. For example, the tumor suppression gene TP53 is mutated in a high percentage of cancer cases. If this mutation can be reliably repaired, our ability to treat a number of cancers could be significantly improved. There are recent results suggesting that this may indeed soon be the case (for example, treatment with APR-246).
