Advantages of Scanning

  •  Higher cure rate- early discovery of tumours mean more likely to be cured soon so it does not grow.
  • Reduces unnecessary operations
  • Faster diagnosis the faster the tumour is discovered the earlier the tumour can be diagnosed.
  • Safe in the case of MRI- MRI do not use x-rays therefore radiation will not be released and cause the patient harm.

Disadvantages of Scanning

  •  Can break down- slight problems can make the equipment or scanner damage and break down easily.
  • Can be dangerous for staff to use as they can be exposed to mass of ionising radiation.
  • MRI scans require patients to lie still for hours in a closed area, which can become uncomfortable and claustrophobic.
