Cancer has traditionally been understood as a disease caused by genetic mutations. However, through this course, I have come to realize that epigenetics also plays a crucial role in the development of cancer. 

Epigenetics involves the regulation of gene expression without changes in the DNA sequence itself. It is noteworthy that gene expression can be regulated through mechanisms such as DNA methylation, histone modification, and chromatin remodeling. Changes in gene expression patterns can lead to the development of cancer cells.

Understanding that there are causes of cancer beyond genetic mutations is important. If we consider only genetic mutations as the cause of cancer, treatments would focus solely on analyzing DNA sequences. However, if the cause lies in epigenetics, simply examining DNA sequences would not suffice to uncover the reasons for the cancer. Knowing that epigenetics can also be a cause of cancer broadens the horizons of cancer treatment, enabling more diverse approaches for treating patients.

Numerous studies have been conducted to demonstrate how epigenetics can explain cancer. Among them, research on the epigenetic regulatory factor known as the Polycomb group protein has been significant. Polycomb proteins play a role in repressing genes during development. Abnormalities in these proteins can disrupt gene expression and completely alter the future of cells.

So, how should our approach to treatment expand in the future?
Firstly, both genetic and epigenetic factors should be considered in cancer diagnosis. This could allow for the detection of early signs of cancer that have not been discovered previously, enabling prompt action. 

Additionally, we could consider methods such as artificially introducing proteins that regulate genes, similar to how hormone injections are administered when there is a deficiency. Using proteins to properly regulate gene expression could potentially prevent cells from developing into cancer cells. 

By embracing a broader understanding of the genetic and epigenetic factors involved in cancer, we open up new possibilities for early detection, prevention, and more personalized treatments, enhancing the efficacy of our approaches against this complex disease.
