"Hi, my name is Lauren, and I am fundraising for my Stepdad Jim. We live in Dennyloanhead, a village in Central Scotland.
On the 6th of July, 2023, Jim was diagnosed with stage IV Cancer. At 48 years of age, Jim presented fit and robust and yet was given a devastating prognosis.
Unable to determine the primary source of Jim's Cancer, the NHS had very little to offer, and Jim and our family were faced with the bleak reality of his disease.
The Cancer
Jim was told he had one very small area of metastasis in the peritoneal cavity and several nodules of metastasis in both lungs. From a PET scan and a CT scan, there was no sign of a primary tumour. The histological investigations of the biopsy from the peritoneal met showed the cancer was an adenocarcinoma which was likely of Gastrointestinal tract origin. Despite the stage IV status, Jim was advised he had a very low volume of disease and told not to rush into treatment.
At this point, Jim was informed his cancer was not curable and palliative chemotherapy would be the only treatment available.
As a family, we were devastated, confused, and in shock. Life had changed in an instant.
Doctors advised that there was no value in further investigations to try and locate a primary tumour. However, after pushing for a second opinion, this decision was overruled, and a vital colonoscopy was performed. Unfortunately, this did not find a primary tumour, leaving Jim's official cancer status in the unfavourable bracket of a ' CUP Cancer' ( CUP = Cancer of Unknown Primary).
A CT scan on the 2/8/23 showed some progression of disease in the peritoneum and lungs, and Jim was advised to start Chemotherapy.
