Breast Cancer Facts

Breast Cancer is caused by a mutation of two genes, BRCA-1 and BRCA-2. One out of every 400 people carry this mutated gene. Men have a lesser chance of gettting breast cancer, having a .26 percent chance of developing it. For every 400 men with breast cancer there are 40,000 women with breast cancer. There are about 212,600 new cases of breast cancer each year and about 40,200 expected deaths. The following table shows the precent increase in the risk of women getting breast cancer with age.

                                              Table 1: Percent chance of breast cancer by age
Age                          Percent in Women        
30 .15%
40 .48%
50 .92%
60 1.28%
70 1.5%
80 1.54%


Hardy-Weinberg Equation

If a Population stays the same with out change it is said to be in equilibrium. When we established our begining population, we took into account the factors involved in the Hardy-Weinberg rules:

*Large populations
*No gene migration
*Mutation
*Rrandom mating

     The basic genetic equation p2+2pq+q2=1 states that in the absence of other factors, genetic makeup of population does not change.
