What is pancreatic cancer?
Pancreatic cancer is a type of malignant tumor that originates from the abnormal growth of cells in the pancreas. It is known for being highly aggressive and having a poor prognosis. The pancreas is a vital organ located deep within the abdominal cavity, divided into the head, body, and tail. It plays a key role in producing digestive enzymes and hormones. Pancreatic cancer often presents no obvious symptoms in its early stages and is frequently diagnosed only after it has advanced, making treatment more difficult.
Although the exact causes of pancreatic cancer are not fully understood, several factors have been linked to its development:
- Smoking: Smoking is one of the leading risk factors for pancreatic cancer. Chemicals in tobacco can damage pancreatic tissues and potentially lead to cancer. Quitting smoking is one of the most important steps in reducing risk.
- Genetic factors: Certain genetic mutations and a family history of pancreatic cancer can increase the risk. Individuals with a family history may benefit from regular screening for early detection.
- High blood sugar and pancreatitis: People with long-term diabetes or chronic pancreatitis are at a higher risk. Maintaining good blood sugar control and pancreatic health is important for prevention.
- Obesity: Obesity is a risk factor for many cancers, including pancreatic cancer. Healthy weight management and proper nutrition can help reduce this risk.
- High-fat diet: Diets high in fat may increase the risk of pancreatic cancer. A healthy diet rich in fruits, vegetables, and whole grains, with limited intake of fats and balanced protein, is recommended.
While these factors may contribute to the development of pancreatic cancer, not all patients have known risk factors. Conversely, some individuals with risk factors may never develop the disease.
Most importantly, if you have any concerns or symptoms related to pancreatic cancer, please consult a doctor as soon as possible. Only a professional medical team can perform detailed evaluations and make an accurate diagnosis. Regular health checkups and maintaining a healthy lifestyle are also essential for prevention

Symptoms of Pancreatic Cancer
Pancreatic cancer often presents no clear symptoms in its early stages, making early diagnosis difficult. However, in advanced stages, the following symptoms are commonly observed:
- Upper abdominal pain: Patients often experience persistent pain in the upper abdomen or the back of the abdominal cavity.
- Digestive issues: Symptoms may include nausea, poor appetite, malabsorption of fats, and diarrhea.
- Jaundice: Tumors may compress the bile ducts, leading to jaundice, dark urine, and digestive discomfort.
- Weight loss: Malnutrition is a major issue in pancreatic cancer, resulting in significant weight loss.
Diagnosis of Pancreatic Cancer
Diagnosing pancreatic cancer typically requires a combination of different tests. Common diagnostic methods include:
- Imaging studies: Ultrasound, CT (computed tomography), and MRI (magnetic resonance imaging) are used to detect tumors in the pancreas.
- Endoscopic procedures: Endoscopic retrograde cholangiopancreatography (ERCP) helps assess abnormalities in the structure of the pancreas and bile ducts.
- Tumor markers: CEA and CA19-9 are commonly used as tumor markers for pancreatic cancer. However, due to limited specificity, they are mainly used for follow-up and monitoring rather than for diagnosis alone.
Proton Therapy for Pancreatic Cancer
Proton therapy is a highly precise form of radiation treatment that can be used for pancreatic cancer. It takes advantage of the unique physical properties of protons to deliver high-energy doses directly to the tumor, accurately targeting and destroying cancer cells while sparing the surrounding healthy tissue as much as possible. Compared to traditional X-ray radiation, proton therapy typically causes fewer side effects and may offer a higher treatment success rate.
