Pros and Cons of Screening

At LungHealth UK we are keen that you have as many facts as possible before taking a decision to have early detection of cancer services. We hope that you will find the table of pros and cons of cancer screening below a useful tool in coming to that decision.

Pros Cons
  • Cancer screening may give you an indication of cancer before any symptoms develop.
  • Cancer screening may find cancer at an early stage when treatment is more likely to be curative.
  • If cancer is diagnosed at an earlier stage, treatment is more likely to be successful.
  • Cancer screening can miss a number of cancers and provide false reassurance: no cancer screening test is 100% accurate. 
  • Cancer screening can lead to unnecessary worry and investigations when there is no cancer present.
  • A positive screening result may cause anxiety by diagnosing a slow-growing tumour that may never cause any harm or symptoms.
