Pancreatic Cancer Information
In-depth overview of causes, symptoms, and screening guidelines
Causes of Pancreatic Cancer
The causes of pancreatic cancer are complex and not fully understood. However, certain risk factors have been identified:
Genetics: Family history of pancreatic or related cancers, and specific genetic syndromes such as BRCA mutations, Lynch syndrome, and familial atypical multiple mole melanoma (FAMMM) syndrome.
Lifestyle Choices: Smoking, heavy alcohol consumption, and obesity.
Chronic Conditions: Long-term diabetes, chronic pancreatitis, and non-alcoholic fatty liver disease.
Environmental Factors: Exposure to certain toxins in workplaces, such as chemicals used in dry cleaning and metalworking.
Age: The risk increases significantly after the age of 60.
Diet: High consumption of red and processed meats, and low intake of fruits and vegetables.
Infections: Chronic infections like Helicobacter pylori (H. pylori) may slightly increase the risk.
Symptoms of Pancreatic Cancer
Pancreatic cancer often goes unnoticed in its early stages. Many symptoms are vague and easily mistaken for other conditions:
Unexplained weight loss: A sudden drop in weight without changes in diet or exercise.
Jaundice: Yellowing of the skin and eyes due to blocked bile ducts.
Digestive issues: Nausea, vomiting, diarrhea, or changes in appetite.
Abdominal pain: Pain that radiates to the back, often worse after eating or lying down.
Fatigue and weakness: Persistent tiredness that doesn’t improve with rest.
Dark urine: Caused by bilirubin buildup in the blood.
Light-colored stools: Due to lack of bile reaching the intestines.
New-onset diabetes: Especially in individuals over 50 with no prior history of diabetes.
Blood clots: Unexplained blood clots in the legs (deep vein thrombosis) or lungs (pulmonary embolism).
Itchy skin: Often associated with jaundice.
Screening for Pancreatic Cancer
Screening for pancreatic cancer is not routine but is recommended for high-risk individuals. Here’s a concise overview:
Who Should Screen?
- Family history: Two or more first-degree relatives with pancreatic cancer.
- Genetic syndromes: BRCA mutations, Lynch syndrome, FAMMM syndrome, Peutz-Jeghers syndrome, or hereditary pancreatitis.
- Chronic conditions: Long-standing diabetes or chronic pancreatitis.
- Age: Over 50 with unexplained weight loss or new-onset diabetes.
Screening Methods
- Endoscopic Ultrasound (EUS): Examines the pancreas and allows biopsies.
- MRI/MRCP: Detailed imaging of the pancreas and bile ducts.
- CT Scans: Detects tumors using cross-sectional images.
- Blood Tests: CA19-9 and CEA biomarkers (not specific but helpful).
- Genetic Testing: Identifies inherited risk factors.
Challenges
- Lack of specific biomarkers.
- Cost and accessibility of advanced tests.
- Risk of false positives.
