This is a huge guideline from NICE on diagnosing cancer, far too big to summarise easily in a blog. I have done a separate post for diagnosing cancer in children.
In reality the 2 week wait referrals will be directed by what is on the referral form, so I have ignored those bits of the guideline.
There is also a lot of information about when we should be referring to direct access services and when we should be doing simple blood tests. I would strongly encourage you to invest half an hour in skim-reading it.
