I think they are just getting better are diagnosing many cancers earlier, @Blossom1961. And many who have chemo then require ECGs, as it can damage heart tissue badly. :(
Tho when I got my 'biopsy call back' in the weeks leading up to Xmas last year - they tried to say the long wait between my ultrasound & biopsy (4 weeks) was as 'they always get busy at this time of year' - as if suddenly, everyone gets diagnosed with possible BC! FFS - it was weeks before ANY of the public holidays!! I finally had it on Dec 23rd.
Sadly it looks like they are underfunded/understaffed/under prepared for the numbers of people coming thru :(
