KARACHI: Scientists have learned more about the hidden role of epigenetics, the study of how genes are modified, in determining cancer development.
According to studies from The Institute of Cancer Research, "dark matter" could change cancer detection and treatment methods.
And it could lead to the development of new diagnostic tests for the disease, which would facilitate the customisation of therapies. However, this is still far off, as research is still in its infancy.
Most people associate genetics with structural changes to the DNA code passed down through generations. As a result, there has been a tremendous emphasis on how these gene changes contribute to cancer development.
In recent years, scientists have discovered epigenetics, a more complex process. Epigenetics is the study of how a person's behaviour and environment can impact the functioning of their genes.
People's epigenetics varies as they age and react to their environment and lifestyle. Epigenetics can not modify the DNA coding, but it can regulate gene access and is increasingly believed to have a significant role in cancer development.
