Can you explain to me how radiation therapy kills cancer cells?
User Submitted Interview Answers
1.
The radiation kills the cancer cells by damaging the dna of the cell and making it unreproducable.
2.
It uses high energy X rays to interact with body tissue to produce ions which kill the tumor cell. Both electrons and photons can be used depending on the depth of the tumor.
3.
Attack the DNA molecules in the cancer cells and destroy the cell.
4.
High does radiation breaks the bond the the cancerous cell, this can be a single bond break or a double bond break dependent on the event of interaction. As treatment is given to the patient at a fixed interval, i. E every day, the cancerous cell will not be able to recover as quick as the damage.
5.
By disrupting the DNA structure and prevengting growth in the cell cycle stage of division.
6.
Radiation affects the cells cell cycle. It targets the DNA structure and it destroys its ability to reproduce. Normal cells can recover from this but tumour cells can not.
7.
Radiation thrapy damages the cancer cells DNA killing the cell and therfore shrinking the tumour.
8.
Radiation therapy kills cancer cells by damaging their DNA (the molecules inside cells that carry genetic information and pass it from one generation to the next). Radiation therapy can either damage DNA directly or create charged particles (free radicals) within the cells that can in turn damage the DNA. Cancer cells whose DNA is damaged beyond repair stop dividing or die. When the damaged cells die, they are broken down and eliminated by the body’s natural processes.
9.
High dosage of radiation damages the DNA of the cancerous cells which kills them and leave the healthy cells to repair and regrow.
10.
The xrays destroys the dna of the cancer cells causing them to break down and die and unable to grow and spread.
