High-dose radiation has the ability to kill cells or prevent them from dividing. Since cancer cells divide and multiply much faster than normal cells, radiotherapy has a higher effect on cancer cells than on normal tissues. Furthermore, healthy cells have a much greater capacity to repair and heal themselves compared to cancer cells. During the 'Planning' phase, precise calculations and modeling are performed to ensure that the diseased tissues receive the maximum radiation dose, while surrounding normal tissues receive the minimum. Thus, the treatment is effectively applied towards the determined target.
