Can virus kill cancer cells ?

Hello awesomites !Today's topic is short ,simple and easy to understand.

Cancer is basically a disease where there is abnormal growth of cells in body and sometimes it is also malignant that is ,it can spread from one organ/site to another.These newly formed cells can disturb normal cycle of other cells .When a  cell suffers DNA damage from cancer,a virus or radiation a group of protein complex MRN is sent to repair DNA.MRN is protein complex ,it consists of Mre11,
Rad50 and Nbs1 .In eukaryotes initial processing of double strand DNA breaks prior to repair by homologus recombination or by non-homologus joining.
When a DNA virus is present in the cell,MRN instead focuses on removing it.
If both DNA damage & a DNA virus are present in a single cell .The MRN complex is unable to manage both threats at once and ends up ignoring the virus .
These new findings imply that scientist might be able to form a virus that targets and  kills only cancer cells.

Keep smiling:)
Good day:)
