What are the effects of radiation-induced cell transformation?

I can't seem to find the answer, is cell transformation good or bad?

How about radiation induced ones to humans?What are the effects of radiation-induced cell transformation?
Radiation-induced cell transformation can cause changes or mutations within the genetic code in a cell.



Cell transformation is good when these transformations are calculated and if they are placed in desirable areas where the results are more or less predictable to be beneficial for the cell.



However, during radiation-induced cell transformation, the changes incurred on the genetic material is NOT controlled and NOT specific in places where there may be benefits from the mutations. For example, it can change the sequence of the gene to make essential amino acids or proteins in a cell. Even a single amino acid change in a gene sequence can cause a change in the structure and mechanism of the cell, and can even kill the cell if it doesn't adapt fast enough to fix these changes.



Radiation-induced cell transformation in humans, can not only cause malformations in offspring thru the gametes, but can also cause cancer if normal vegetative cells are affected.



However, this method is also used in chemotherapy, where the healthy cells are bombarded with chemicals that render it dying or dead, which signals the body to dispose of them immediately--like causing an overhaul of body cells just to get rid of the cancer.
