alt Hacker NewsFWIW it's commonly the case with cancers of abdominal organs: stomach, pancreas, liver, kidney, etc. These cancers are frequently not diagnosed until at an advanced stage. Symptoms tend to be nonspecific, overlap with ubiquitous conditions like constipation, gastritis.
A goal of research is improving early detection of these cancers but it's an uphill battle. It's difficult to increase providers' "index of suspicion" of seemingly "minor" complaints.
That’s a generalization, pancreatic cancer is often extremely lethal, depending on the type and case the survival rate can be as or more grim than glioma. Bowel and urinary cancers including kidney cancer are often very treatable and survivable when discovered due to symptoms. I don’t think it’s helpful to group all abdominal cancers as being uniquely or especially bad or late discovered. Likewise for the particularly aggressive or advanced cancers these types of announcements and trials rarely translate to major changes in prognosis. More typical if there is any positive result it looks like additional weeks or at best months of aggressive treatments rather than significant ”cure” rates.
