DNA damage, risk for tumor diseases

DNA damage, risk for tumor diseases

Damage to the DNA of cells is not always repaired by the cells. Some remain and persist for months or years, increasing the risk of harmful mutations, which can also cause serious diseases.

According to the Wellcome Sanger Institute in the United Kingdom, which published the study in the journal Nature, over time, the body's cells accumulate errors in their genomes, which are mutations that directly affect the book of life, where one letter in DNA can be mistakenly replaced by another.

While DNA is usually repaired by cellular repair mechanisms, there are cases where this does not always happen.

The study is important because it changes the way experts consider mutations, when they are harmful and when they are normal, and predict the possible evolution of tumor diseases.
