ok is this considered biology and could i use it for a report in which im supposed to write about wat i learned form the article....A SUDDEN TURN: Gene Upshaw was diagnosed with pancreatic Gene Upshaw, the executive director of the National Football League Player's Association—the union for NFL players—died late Wednesday evening of pancreatic cancer while vacationing in California's Lake Tahoe. Doctors diagnosed the 63-year-old Hall of Fame offensive lineman with the disease just four days earlier.Upshaw was a guard for the Oakland Raiders from 1967 to 1981. He played in seven Pro Bowls and three Super Bowls. He served as head of the NFL player's union for 25 years.According to Bloomberg News, Upshaw's wife, Terri, took him to a hospital on Sunday, August 17th, because he was having trouble breathing. A biopsy revealed, much to everyone's surprise, that he had advanced pancreatic cancer.In March, actor Patrick Swayze—star of the hit 1980s film Dirty Dancing—revealed he had been diagnosed with the illness in January. Doctors' reports indicated they had caught his cancer relatively early.The pancreas secretes hormones and enzymes to digest our fats. One of those hormones is insulin, which prompts the body to use sugar in the blood rather than fat as energy. Its levels are low in diabetic patients, who suffer from abnormally high blood sugar.Only one fifth of Americans diagnosed with pancreatic cancer survive for a full year, according to the American Cancer Society, and it is the fourth leading cause of cancer death in the country.How does the disease develop without noticeable symptoms and then kill so quickly?To find out, ScientificAmerican.com called Allyson Ocean, an oncologist at New York–Presbyterian Hospital/Weill Cornell Medical Center, who specializes in gastrointestinal cancers including pancreatic cancer. An edited transcript follows:Why does pancreatic cancer kill so quickly?Pancreatic cancer is typically diagnosed at a late stage because it doesn't cause symptoms until it's too late. Weight loss, abdominal pain, jaundice [a yellowing of the skin due to toxic buildup in the liver]—those are the most common symptoms. They usually start after the tumor is a significant size. By then, chances are, it has metastasized [that is, spread to other parts of the body].Only about 10 to 15 percent of pancreatic cancers are diagnosed when they could be considered for surgery. And the prognosis is poor even in patients who do have surgery, because it comes back about 85 percent of the time. At best, 25 to 30 percent of patients are alive five years after surgery.When doctors do pancreatic cancer surgery, they take out 95 percent of the pancreas, including the tumor, and then they leave a small remnant of the pancreas in there that serves [the insulin-producing] functions.If a person can live without a fully functional pancreas, then what, ultimately, kills most pancreatic cancer patients?When most patients die of pancreatic cancer, they die of liver failure from their liver being taken over by tumor.What precludes doctors from performing surgery on late-stage patients like Upshaw?We don't do surgery if the tumor has already spread outside the pancreas, because there's no survival benefit in removing the tumor. We also sometimes can't do surgery [when the tumor] involves the great blood vessels, the superior mesenteric vein and superior mesenteric artery. Those are the main vessels that come off of the aorta, the main artery in our body. If the tumor is wrapped around those blood vessels, then we can't take it out.Why is this particular cancer so aggressive?Because of the nature of the tumor cells. They escape the treatments, they hide out, and then they come back. And they grow again and they affect the liver and then they kill people.What are the biggest risk factors for pancreatic cancer?The biggest known risk factors are smoking and family history—it can be a hereditary disease. Then there are some other more obscure risk factors, such as defects in the anatomy of the pancreas, but that's very rare.What factors affect how early a person gets diagnosed?Depending on where the cancer is diagnosed in the pancreas, it can affect how soon it's diagnosed. For instance, if the cancer is in the head of the pancreas, which is close to the common bile duct, and it grows and it causes obstruction of the common bile duct, a patient can get jaundiced. And then they could [show symptoms] sooner than someone whose pancreatic cancer is in another part of the pancreas, like the tail. They would not present with jaundice, so we would not have a clue that there was necessarily anything wrong with them.What are some of main symptoms as the cancer progresses?Unexplained weight loss, abdominal pain, nausea, vomiting. Back pain is another one, because the pancreas is very posterior in the body. Back pain is also the most common complaint that p
