Pancreatic cancer disease is one of the most aggressive and deadly types of cancer, 40 year survival rate stands at 23.2%. To give you some context, 2 out of 3 people diagnosed with pancreatic cancer die from the disease in less than five years after diagnosis. It accounts for about 4% of all new cancer cases, but pancreatic cancer death is so painful because it has no early symptoms or reliable screening methods for early diagnosis. Due to a variety of clinical symptoms that mimic other pancreatic conditions, such as gastric irritation and gallstones, until late stages the pancreas can often not be scanned by CT or MRI and this makes it extremely tough to detect on time. The use of other symptoms like body weight loss enlarged liver or fatty changes in pre-cancerous are more helpful in detecting its existence. Pancreatitis is caused by a build-up of pancreatic enzymes that digest protein, fat, and carbohydrate. Pills or over-the-counter medicines can trigger the inflammation. Gastrointestinal bleeding is associated with 90% of the cases of colon cancer. Cancer risk increases with age and rates are higher in those who live to old age. 40% mortality rate within 15 years after diagnosis is seen in people 75 years and older, while 50% mortality rate.
