NextGen DNA sequencing technology to reduce genetically linked breast cancer.

The NextGen DNA sequencing technology is being met with a great deal of excitement, because it will provide a more comprehensive testing for the BRCA1 and BRCA2 breast cancer genes. These are the genes that are related to inherited cancerous mutations.

By next year, the NextGen DNA sequencing technology is supposed to cut the wait times of patients from six months down to two months.

“The difference here now is rather than sequencing (DNA) 50 samples at a time, we’re sequencing millions and millions of DNA at a time,” said Dr. Aly Karsan, medical director at the Centre for Clinical Diagnostic Genomics which handles the testing.

What is BRCA1 and BRA2

BRCA1 and BRCA2 belong to the human class of genes known as tumor suppressors. The mutation of these two genes is directly linked to hereditary ovarian cancer and breast cancer. If a woman inherits these harmful mutations, her likelihood of developing breast cancer or ovarian cancer goes up significantly.

About the NextGen DNA Sequencing Technology

DNA sequence represents a single format against which a broad range of biological phenomena can be projected for high-throughput data collection. The cost of DNA sequencing has been on the decline and becoming more readily available as it becomes more readily available. These new technologies are continuously evolving, and the development of robust protocols for generating sequencing libraries continues to grow. The potential is unimaginable and endless. Next-generation DNA sequencing is likely to significantly speedup biological and biomedical research, through the use of comprehensive analysis of genomes, transcriptomes and interactomes, which are becoming less expensive, more routine and more readily available.

How DNA Sequencing Will Improve Breast Cancer Diagnostics

According to the Canadian Cancer Agency new DNA sequencing technologies will improve the data and reduce turnaround times and costs for patient testing. According to Dr. Juliet French from the University of Queensland, recent studies have recognized areas within the human genome where DNA sequence variations are linked with an increased risk of breast cancer. A number of these areas don’t include any recognized genes. This indicates that these unannotated genes are to blame for the risk of breast cancer. The understanding of how DNA sequence variations in these areas can contribute to breast cancer combined with the use of the new NextGen DNA Sequencing technology will allow for much quicker identification of these risk factors.

DNA Sequencing to Prevent Cancer

We’ve been talking about how DNA sequencing will help to diagnose BRCA1 and BRCA2 based breast cancer, but what if it could also be used to prevent the development of breast cancer. That almost sound like something out of a science fiction movie doesn’t it? We should be excited! This is ground breaking and not only will women (and men) be diagnosed earlier the future potential for the same type of technology to be able to ensure they receive treatment before the cancer has an opportunity to develop. That treatment might include preventative steps like a mastectomy or it might include some type of drug treatment. We do not know what the future will bring.

Cancer is the biggest disease that doctors and scientists fight to cure. In the future, DNA testing will become very affordable and it will be used to identify women who are at risk because they have the defective gene.

Every one of our families could be affected by this news. Our mothers, grandmothers, daughters, sisters, aunts have the potential to benefit from this latest technology by early diagnosis is the BRCA1 and BRCA2 types of breast cancer and ovarian cancer.

This is the type of news we have all been waiting to hear more about. Now let’s hope it becomes readily available sooner rather than later.
