Hi Mummy13, i would have thought the radiotherapy is still working at the moment, its not the lump its what is happening behind the scenes i.e has the radiotherapy controlled the tumour and not got any bigger, this is what the scan will show, sometimes the lump remains but is a lot smaller. I know it's not easy but try not to worry at the moment unless you are feeling unwell or concerned, you can always give your team a ring. Best wishes ,take care.
