Pancreatic Cancer
About Pancreatic Cancer
Pancreatic cancer is a disease in which malignant cells form in the tissues of the pancreas, an organ located behind the stomach that produces enzymes for digestion and hormones like insulin. It is often described as aggressive and frequently diagnosed at a later stage.
Common Symptoms
- Abdominal pain that radiates to the back
- Unexplained weight loss
- Jaundice (yellowing of skin or eyes)
- Loss of appetite
- Nausea and vomiting
- New-onset diabetes or worsening existing diabetes
- Fatigue
- Dark urine
- Light-colored stools
- Itchy skin
Diagnosis
Diagnosis commonly begins with a physical exam and review of symptoms, followed by imaging tests such as CT scans, MRI, or ultrasound. A biopsy, which involves taking a tissue sample from the pancreas for microscopic examination, is typically necessary to confirm the presence of cancer.
Causes
The exact causes of pancreatic cancer are not fully understood, but certain risk factors have been identified. These include smoking, obesity, a long-standing history of diabetes, chronic pancreatitis, and a family history of pancreatic cancer.
Treatment Overview
Treatment approaches for pancreatic cancer are varied and depend on the stage and location of the cancer, as well as the patient's overall health. Conventional treatments often include surgery, chemotherapy, and radiation therapy, which may be used alone or in combination. Some individuals also explore complementary therapies, such as nutritional support or acupuncture, usually alongside standard medical care, to help manage symptoms or side effects.
Prognosis & Outlook
The prognosis for pancreatic cancer can be challenging, as it is frequently diagnosed in advanced stages. Outcomes often depend on the stage of cancer at diagnosis, the specific type of pancreatic cancer, and how well the cancer responds to treatment. Early detection is generally associated with a more favorable outlook.
Types & Variants
Pancreatic adenocarcinoma
This is the most common type, accounting for over 90% of cases. It starts in the exocrine cells that line the ducts of the pancreas, which produce digestive enzymes.
Pancreatic neuroendocrine tumors (PNETs)
A less common type that forms in the hormone-producing endocrine cells (islet cells) of the pancreas. These tumors can be functional (produce hormones) or nonfunctional.
