A “BRAVE, fearless and inspirational” woman has died, 18 months after being diagnosed with multiple brain tumours.

Jenny Weller, from Burgess Hill, was diagnosed with a primary tumour in her lung and five secondary tumours in her brain, as well as others in her neck and pelvis, in September 2020.

Following her terminal cancer diagnosis at the age of 35, the personal trainer launched a year-long series of fundraisers for the charities Brain Tumour Research and ALK Positive UK. 

She raised more than £20,000 for Brain Tumour Research under the banner “WellerFest”.

Jenny had undergone a craniotomy to remove the largest of her brain tumours and used targeted drug therapy to try to slow the growth of the others but progression saw her undergo a three-week course of radiotherapy last year and in December she developed a further nine brain tumours.

Her health continued to deteriorate and she died in a hospice in the early hours of Wednesday morning with her husband, Steve, by her side.

Breaking the news of her death on WellerFest’s Facebook page, Jenny’s stepson Paul said: “It is with such sadness that we need to make everyone aware that our Jen passed away at 2.10 this morning, peacefully in her sleep with Steve beside her. 

“What an inspirational and brave woman she was to put up such an incredible fight.

“Jen has touched so many of our lives and she was loved by so many. 

“Dad would like to thank everyone for the ongoing love and support we have received.”

 Hundreds of people have responded to the announcement of Jenny’s death by leaving messages of love and support.
