(Natural News) Normalizing the oxygen supply in tumors may inhibit the progression of cancer, according to a study published in the journal Nature. The scientific community has well established the mechanism behind cancer onset. Experts note that the disease stems from a single cell's DNA mutation, either by chance or due to carcinogenic factors, which is then followed by the rapid expansion of the abnormal cell.
According to scientists, these harmful genetic mutations affect the functions of otherwise normal cells. However, the experts say that these mutations are necessary for the growth and survival of cancer cells. Health experts also explain that aside from these genetic changes, tumor cells also exhibit epigenetic changes. These changes have something to do with how genes are expressed.
As part of the new study, the researchers have examined more than 3,000 patient tumors to see how hypermethylation contributes to cancer onset. The scientists explain that hypermethylation is a process where high amounts of methyl groups are added to the cell's DNA. The researchers stress that hypermethylation dampens the expression of tumor suppressing genes as a result, which then speeds up abnormal cellular behavior and excessive tumor growth.
