        <p>For many years, doctors and scientists have been looking for a
cure for cancer and especially for breast cancer. A vaccine has eluded
doctors for many years and they continue on their quest for finding one.
Doctors are trying out new ways to improve the already existing forms of
diagnoses and treatment. It has been of major concern that, the methods
of diagnoses in use today have been very invasive and that they can only
be used when the disease begins to show signs and symptoms. The methods
of diagnoses have also been known to increase chances of developing the
disease they are supposed to be diagnosing. This is because, repeated
exposure to radiation could result in cancer. <br><br> Some of the
methods in use today include; ultrasound, MRI, digital mammography,
ductal lavage, image guided breast biopsy and PET scan. Most of these
tests rely on ultra sounds, although some do not, such as MRI and PET
scan. Sometimes these methods can be used together in order to give more
conclusive results for breast cancer detection. For example, an
ultrasound can be used together with a needle biopsy. Modern ultrasound
is able to detect whether a lump is cancerous or malignant. These results
can further be supported and confirmed by use of a needle biopsy.
<br><br> Most of these methods are mainly advances on the old forms of
diagnosis. They have been modified in order to give clearer results and
also to produce results faster. For example, the old type of mammograms
used x-ray film but the new types of mammograms use computer codes that
can be read using a computer. It is also possible to make changes on
these codes before finally printing them on film. This new method helps
in giving very clear images that prove very helpful to the doctor when
making interpretations of the film. The images can also be saved on the
computer for comparison purposes and copies can be printed out when the
need arises. <br><br> Some methods are also in use for detection of
cancerous cells in the denser parts of the breast where normal methods
may be unable to detect them. This method is also a type of mammogram
which uses x-rays. The method focuses on areas that have growth of blood
cells which could be an indicator of cancer. The process is very fast and
takes less than ten minutes. However, scientists are still at work and
many of the procedures are still under trial. It is hoped that in a few
years, more progress will have been made and it will become possible to
diagnise breast cancer earlier and help save more lives.</p>        <!--
