Topp Twins have now shared an update on how they're both doing in their respective treatments.
"Jools is resting and recovering after a week of radiation on a new tumour, and it has reduced her pain - so keeping our fingers crossed" they wrote.
In four weeks time, she has an MRI scan to check if the tumour has been eradicated or reduced.
Lynda has completed her third chemotherapy session and has her ' good days and bad days'.
"It is a difficult treatment to deal with, but she has a good support team and a woolly hat from mum to keep her head warm. She has another 3 months of Chemo before any tests or appointments with her Oncology team at Christchurch Hospital" they wrote.
Jools has completed her treatment so she can travel to where Lynda is and so they are planning to reunite on their birthday in Mid-May.
The twins then thanked their supporters who have been helping them via the Give A Little page. As of now, a total of $117,790 has been donated.
