Computed Tomography Case Study

Computed Tomography (CT) scan involves the use of x-rays, a form of ionizing radiation, CT scan is used to detect and diagnose the presence and recurrence of tumors in human body and also provides the stage of a cancer. Several case studies have shown that CT scan can be effective in both colorectal cancer and lung cancer screening. Exposure to ionizing radiation is caused to increase the risk of cancer. Children may be at higher risk because usually children are more sensitive to radiation than adults and have a longer life expectancy. Women also at a somewhat higher risk than men of developing cancer by receiving the same radiation exposures at the same age. Low Dose CT scan has been introduced for minimizing the radiation effects as high
