29 Dec Understanding Risk Factors for Pancreatic Cancer
The pancreas is a gland located deep within the abdomen, situated between the stomach and the spine. It performs two main functions for the body. It produces enzymes that aid in digestion and create hormones, such as insulin, that help manage blood sugar levels. An awareness of pancreatic health and the factors that can lead to pancreatic cancer is a component of overall wellness.
What Is Pancreatic Cancer?
Pancreatic cancer begins when cells in the pancreas develop mutations, causing them to grow uncontrollably and form a tumor. These cancerous cells can interfere with the normal functions of the pancreas. There are two main types of this form of cancer, categorized by the type of cell from which they originate. The most common form is pancreatic adenocarcinoma, which arises in the exocrine cells that line the ducts of the pancreas. These ducts produce digestive enzymes. Less commonly, cancer can form in the endocrine cells of the pancreas, which are responsible for hormone production. These are known as pancreatic neuroendocrine tumors (NETs) or islet cell tumors.
The location of the tumor within the pancreas can influence the types of symptoms that appear. Because of the pancreas’s deep location in the body, tumors may grow for some time before they cause symptoms. When symptoms do arise, they can be nonspecific and may include abdominal pain, unintended weight loss, and jaundice.
What Causes It?
The precise cause of pancreatic cancer is not fully understood. Researchers have identified several risk factors that may increase a person’s chance of developing the disease. A combination of genetic and lifestyle factors appears to contribute to its development.
Some risk factors are modifiable, while others are not. Age is a significant factor. The risk of developing cancer increases with age. A personal or family history of pancreatic cancer or certain genetic syndromes can also elevate risk. Chronic pancreatitis, a long-term inflammation of the pancreas, is another established risk factor. Diabetes, particularly when it has been present for many years, is linked to a higher risk as well.
Lifestyle choices also play a role. Smoking tobacco is one of the most well-established risk factors for pancreatic cancer. Obesity is another factor, as individuals who are overweight have a greater likelihood of being diagnosed. Diets high in animal fats may also contribute to an increased risk.
How Is It Treated?
The treatment for pancreatic cancer depends on several variables, including the stage and location of the cancer and the patient’s overall health. A multidisciplinary team of specialists typically collaborates to create a comprehensive treatment plan. Surgery offers the possibility of removing the tumor. Surgery is generally an option for patients whose cancer has not spread to other parts of the body.
Chemotherapy uses drugs to kill cancer cells and can be administered before surgery to shrink a tumor or after surgery to eliminate any remaining cancer cells. Radiation therapy uses high-energy beams to destroy cancer cells. Targeted therapy drugs work by focusing on specific abnormalities present within cancer cells, offering another approach for certain types of pancreatic tumors.
Speak Further With a Gastroenterologist
Understanding the elements that contribute to pancreatic cancer provides a foundation for proactive health management. Gastroenterologists are medical specialists who focus on the digestive system, including the pancreas. They can offer personalized guidance based on your specific health profile and family history. A consultation can help clarify your individual risk and determine if any screening or preventative measures are appropriate for your situation.
