subject: Technology for Breast Cancer Diagnosis [print this page] 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.
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.
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.
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.
