Pancreatic cancer cells feed off hyaluronic acid
I have friends that have died from pancreatic cancer, seems like lots of them.

Often found in beauty products and wellness supplements, hyaluronic acid attracts and retains water well. It’s also a major player in the physiology of pancreatic tumors.
Hyaluronic acid, or HA, is a known presence in pancreatic tumors, but a new study from researchers at the University of Michigan Health Rogel Cancer Center shows that hyaluronic acid also acts as food to the cancer cells. These findings, recently published in eLife, provide insight into how pancreatic cancer cells grow and indicate new possibilities to treat them.
“A central driving theme in my research lab is that pancreatic cancer doesn't respond to the common arsenal of treatment approaches. We need to think about this challenge differently,” said Costas Lyssiotis, Ph.D., the lead investigator on the study. He and his team study the metabolism of pancreatic cancer in preclinical models: how cells obtain nutrients and the spectrum of nutrients they utilize to fuel growth and enable therapeutic resistance.
The tumor microenvironment, or the cells that make up the tumor, are a combination of many different cell types, some malignant, some not. A pancreatic tumor’s microenvironment is highly stromal, meaning the mass itself is mostly comprised of connective tissue and non-cancerous immune cells.

products mentioned. Just awful luck, it seemed, in his case. 
Butter was good once, then it became bad
Butter replacements were then good. Now they appear to be getting a bad rap.
Now butter is back to being good.
This is only one example - it also depends on what companies are sponsoring the research and what conclusions they are trying to get to support their product advertising and sales.
It sounds like the HA is a component of the pancreas tumor cell ecosystem - not like it causes the cancer - but it might be a help to the tumor cells and their survival. It is therefore being researched as a drug delivery vector that could target the cancer cells directly and selectively.
This is a good news story not a doom and gloom moment.
Carry on with your supplements and beauty serums. As soon as there is statistical data to prove a cancer link THEN hit the panic switch and order a special trash pick up. 
Summary
In PDAC tissues, HA is secreted from tumor cells and stromal cells through upregulation of HAS in response to tumor–stroma interactions. The secreted HA, or its smaller fragments, may promote tumor cell proliferation, migration, invasion, and angiogenesis through HA‐receptor signaling and also serve as a barrier to access of chemotherapeutic agents to tumor cells. Given these links of HA with cancer progression, targeting HA represents a potential therapeutic approach for treatment of PDAC. There are different approaches of HA‐targeted therapies that include strategies aimed at inhibiting HA synthesis, blocking HA‐receptor signaling, and depleting stromal HA (Fig. Fig.33).
