A lot of discussions take place when it comes to screening of breast cancer. Some say, its screening is dependent on age and others say that it should be performed annually after 40 years.

It can also not be forgotten that a lot of money is needed to get this test done, so annual checkup does not make much sense. In order to solve the problem, Oguzhan Alagoz, a researcher from the University of Wisconin-Madison, has come up with a model, which will help women to decide about what is the best to get breast screening done.

The model is described in Operations Research and is said to be one of a kind, as it contain a lot of data. Some of the things that have been included in the model are age, genetic makeup and other personal risk factors. Moreover, it also provides, screening history for breast cancer as well.

"We illustrate how this extra piece of information might change which decision is optimal and help doctors make better screening decisions", said Alagoz. He further affirmed that he is quite hopeful that model will help people to not to waste unnecessarily on mammograms. It is said that approximately $100 million is being spent on such tests in the US.
