A woman whose mother and his brother died from pancreas cancer have joined calls for faster treatment after diagnosis.
Cancer Pancreatic UK wants a 20 day target for treatment by 2024.
Charlotte Thomas, 43, from Cardiff said he was a "live nightmare" to lose his mother Mavis Dallinger, 59, in 2001, and then his brother Mark Merry, 51, in October 2017.
The Welsh Government said it was expecting people with any cancer to be treated as quickly as possible ".
Pancreatic Cancer UK reported that one in four people diagnosed with pancreas cancer died within one month and three in four died within a year.
Chief Executive Diana Jupp said they were "denied their only chance to survive because they are not being treated quickly enough".
The charity wishes to introduce a jointly funded rapid track operation in the Birmingham University Hospital Foundation Trust.
This was an average break-up for the surgery for 32 patients from two months to just over two weeks – 31 had successfully removed their tumors.
It also wants un-stop clinics to be introduced where all the necessary tests can be made to determine the suitability of people for surgery and that specialist nurses co-ordinate care with the relevant departments.
"In recent years, we have seen an excellent increase in other cancers such as the breast and prostate, and the lack of staggering progress for the pancreatic," said Ms Jupp.
Mrs Thomas said that patients are currently diagnosed, then they will be sent home for weeks and a treatment course is decided.
He described this as a "psychological torture" for his brother.
A Welsh Government spokesman said: "Pancreatic cancer tends to be difficult to detect in its early stages, more treatment.
"Clinicians, however, can prioritize patients based on the severity of their disease."
& # 39; I've been screened from your future & # 39;
Mrs Dallinger was diagnosed in January 2001 and died in December.
When his son began to experience similar symptoms in February 2016, he had a CT scan and was diagnosed with stage 4 pancreatic cancer.
He had spread to her / hers and could not have an operation, so only palliative care could be offered. He lived for 20 months until his death in October 2017.
Mrs Thomas said: "My incredible mum has disappeared and she was 59. She felt her future was spoiled from her, as most people with pancreas cancer feel when they are diagnosed.
"When my brother called me from A & E and said he had the same thing that a mother had been completely destroyed.
"At the beginning, we thought that 15 years had passed since we lost our mother to the same disease, so it's sure that there must be something they can do for my brother – it's & # 39; There must be a different program or different treatment.
"Then we were full of fear because we knew what our mum had passed and we were afraid that it would be exactly the same for Mark. It was a live nightmare.
"For my brother, the worst thing at all was how he psychologically affected. He felt that his future had been robbed and he did not want that person to have cancer.
"Mark was strong steroids for the pain and I think they are affecting his mind.
"He gave him the ketamine and the strongest pain medications that he could find out. He took over his body and his life.
"My nose was in his chest's head when his heart was over. The only reason was that he was no longer suffering."
