Hoffwn bwysleisio bod y newid hwn wedi'i wneud oherwydd bod y prawf sgrinio presennol yn fwy cywir na’r prawf blaenorol. Felly, mae angen prawf sgrinio llai aml ar y rhai nad oes ganddynt HPV.
I would like to reiterate that the change has been made because the current screening is more accurate than previous testing and, therefore, less frequent screening is required for those who do not have HPV.
