Do cancer cells undergo damage under radiation than normal cells

A normally functioning cell will turn into a cancer cell as it accumulates a series of genetic damages that are either self induced (through inherent genetic instability- hereditary) or by multiple incessant external gene damaging agents (viruses, chemicals).
Cells which repair these genetic damages escape themselves from becoming cancerous. But those cells which fail to repair the damaged, vital cancer suppressing genes amongst the catalog of damages inflicted by the previously described methods, will fail to normalise and therefore end up being a revolutionary, adamant and stubbornly growing cell- the malignant cell.
The primary mechanism of action of Therapeutic Radiation in cancer patients receiving them is by causing numerous genetic damages to the cells exposed to it. These damages are way beyond the capabilities of the cancer cells' repair systems. Besides, the weak gene-repair systems of the cancer cell as elucidated in the previous paragraph, results in unavoidable eventuality of the Therapeutic Radiation treatment ie. Cell Death.
The current techniques of aiming the Therapeutic Radiation onto the cancer tissues in the patient, using IMRT, IGRT, VMAT etc. are very accurate and precise in their function. In addition, the genetic damages caused in normal tissues by their exposure to some inadvertently spilt dose of therapeutic radiation can easily be repaired by their intact repair mechanisms which remain unaffected by that small dose. Of course, exposure of normal organs nearer to the cancer growth to full delivered dose can kill them too (usually avoided by adept CT-based radiation treatment planning

yes it can but it can be also no because it depends on the tradition it's passes
