Single Site Testing can be done when
a specific BRCA1 or BRCA2 gene change has been identified in your
family. Consult your doctor. DNA
Direct offers DNA tests for breast and ovarian cancer risk that
range in price from $620 to $3456.
Companies are already beginning to use genetic information to develop
custom drugs for breast cancer. Herceptin
is a very effective anticancer medicine, with revenue last year
of $1.3 billion in the U.S., that is given only to patients who
test positive for a mutation in the HER2 gene.
Geneticists have identified a gene which causes breast cancer to
metastasise, the deadly process by which the disease spreads to
other organs. The SATB1 gene alters the behavior of at least 1,000
other genes within tumor cells and makes cancer cells proliferate.
The findings could pave the way to diagnostic tools that show the
likelihood of the disease spreading and to drugs that prevent or
treat metastasis in breast cancer as well.
