Re: Thyroid cancer: zealous imaging has increased detection and treatment of low risk tumours
Thyroid cancer incidence is more related to private healthcare expenditure of a country, thus indicating many cancers were incidentally detected during ‘over use’ of medical investigations.(1).
These scan-detected, incidental cancers in asymptomatic patients are likely to behave in a biologically less aggressive manner. The treatment for these cancers can be less aggressive than symptomatic cancers but it needs to be confirmed by clinical studies. The best way to encourage research in all incidental cancers is to adopt a new disease category. Cancers of all anatomical sites, which are detected by opportunistic screening, should be termed as ‘Screenomas’.
