Do you also have pancreatic cysts? Let's talk about this in detail!

Maybe you had a `Scan` for some other reason, such as `CT` (Computed Tomography) or `MRI` (Magnetic Resonance Imaging), and the doctor told you that you have a small cyst in your pancreas? When you hear something like that, you can suddenly feel a little scared and nervous, right? Many questions like "What is this? Is it dangerous?" arise in your mind. So, don't worry. Today, let's talk about these cysts in the pancreas clearly and simply.

What is a pancreatic cyst?

Simply put, a pancreatic cyst is a small fluid-filled sac or bubble that forms inside your pancreas, or sometimes on its surface. Think of it like a small water balloon. There are different types of cysts, which are classified according to the cellular materials they are made of. Some types are called neoplastic. Neoplastic means that some of them have the potential to become cancerous over time. Other types are called nonneoplastic. These nonneoplastic cysts do not develop into cancer. So there is nothing to worry about.

What does it mean to have a pancreatic tumor?

Now you're probably thinking, "Okay, so what does that really mean if I have one of these?" While some pancreatic cysts may seem to be related to a condition called pancreatitis, most of the time they develop for no apparent reason, almost by accident. The important thing is, most pancreatic cysts don't cause you any problems. They can just be there.

However, very rarely, a type of tumor called `neoplastic` can be the beginning of pancreatic cancer. Especially if someone in your family, that is, your mother, father, brothers and sisters, has had pancreatic cancer, this risk is slightly higher than others. But it is not common for everyone.

Should I be worried about a pancreatic tumor?

This is the biggest question that many people have. If your doctor sees a pancreatic cyst on an imaging scan, such as a CT or MRI, he or she will immediately classify it as low, medium, or high risk . This classification is based on the nature of the cyst seen on the scan (such as its size and shape) and whether you have any symptoms related to it.

If the tumor falls into the ``low risk`` category, there is probably nothing to worry about. In most cases, nothing can be done.

If the risk is ``medium`` or ``high``, doctors will provide the necessary treatment according to their medical guidelines.

Most of the time, pancreatic tumors are just kept under `surveillance`. Surveillance means that doctors scan them from time to time, asking, "Is this tumor getting bigger? Is it changing shape? Is there anything new?" If a low-risk tumor changes to a moderate-risk tumor over time, a `biopsy` is done to find out more about it. A `biopsy` is done by inserting something like a thin needle, taking a very small piece of tissue from the tumor and examining it under a microscope. That way, the exact type of cells in it can be determined. If a moderate-risk tumor changes to a high-risk tumor, meaning it looks more likely to be cancerous, doctors plan to do surgery to remove it.

How common are pancreatic cysts?

Studies show that pancreatic cysts are found incidentally in about 10% of people undergoing CT scans (Computed Tomography scans) and MRIs (Magnetic Resonance Imaging). They are often discovered incidentally during imaging tests done for another reason, such as stomach problems. Since many people have these cysts and do not show any symptoms, we do not know exactly how many people in the world do not know they have one.

What percentage of pancreatic tumors become cancerous?

This is also an important point. Less than 1% of pancreatic cysts actually turn into cancer. That is a very small percentage. However, about 30% of pancreatic cysts have the potential to become cancerous. These are called precancerous cysts. This is why doctors are always on the lookout for them. But there is good news. These precancerous cysts often grow very large and change dangerously. Therefore, with regular surveillance, that is, with periodic scans, cancerous changes can be identified very early in the process. Then, treatment can be started quickly.

What are the different types of pancreatic cysts?

This is a bit detailed, there are a lot of medical names. But let's keep it simple. It says there are two main types.

Neoplastic or Precancerous Cysts

These are also called `pancreatic cystic neoplasms (PCN).` These are the types we need to look at a little more closely. Some of them are:

• Intraductal Papillary Mucinous Neoplasms (IPMNs): These are the most common type of neoplastic tumor. They develop in the pancreatic duct. The pancreatic duct is a small tube that carries digestive juices produced by the pancreas to the intestines. The fluid inside these tumors is a mixture of pancreatic juices and a thick substance called mucin. Mucin is a component of mucus. This mucin can cause the pancreatic duct to swell and become larger.
• Mucinous Cystic Neoplasms (MCNs): These are not as common as IPMNs. They usually occur in women over the age of 50. They develop in the middle part of the pancreas (the body of the pancreas).
• `Solid Pseudopapillary Neoplasms (SPNs):` These are very rare. They have both a solid and a liquid component. They usually develop in young women in their 20s and 30s.
• Cystic Pancreatic Neuroendocrine Tumors (PNETs): Pancreatic neuroendocrine tumors (also called islet cell tumors) are a rare type of tumor. They are usually solid tumors, but can sometimes appear as cysts.

Non-cancerous cysts (`Nonneoplastic` or `Benign Cysts`)

These do not cause cancer. So there is no need to be too afraid of them.

• Simple Cysts (or Retention Cysts): These are harmless cysts that develop within the pancreas, separated from the pancreatic duct. They are lined with a single layer of epithelial cells. They most often occur in young children.
• Serous Cystadenomas: These are also relatively common and harmless tumors. However, if they grow large, they can sometimes cause problems such as pressing on nearby organs. In that case, they sometimes have to be removed surgically.
• Mucinous Nonneoplastic Cysts: These are harmless, mucin-producing cysts. However, doctors need to examine them carefully to distinguish them from the neoplastic types, which can be cancerous.
• Lymphoepithelial Cysts: These are very rare, harmless tumors. They are most often seen in men.

Important note: There is another thing called `Pancreatic pseudocysts`. Sometimes people confuse these with true cysts. However, a `pseudocyst` is not a new growth like a `tumor`. It is a fluid-filled sac that forms when pancreatic juices leak from the pancreas due to an injury to the pancreas (such as `pancreatitis`). `Pseudocysts` are a benign condition.

What are the symptoms of a pancreatic tumor?

Here's something that may surprise many people: Most pancreatic tumors don't cause any symptoms. Yes, it's true. You may not even notice a tumor. Symptoms only begin to appear when the tumor becomes large enough to block or press on the pancreatic duct, the biliary tract, or the stomach or intestines (gastrointestinal (GI) tract). When that happens, things like this can happen:

• Abdominal pain: The pain often occurs in the upper abdomen.
• Back pain: Sometimes stomach pain can also radiate to the back.
• Loss of appetite: Loss of desire to eat.
• Unexplained weight loss: You suddenly lose weight even though you're not dieting or exercising.
• Bloating: Feeling full even after eating a small amount.
• Indigestion: Feeling like food is not being digested.
• Nausea: Feeling like you're going to vomit.
• Jaundice: The whites of the eyes and skin turn yellow. This happens when bile doesn't flow properly.
• Light-colored, greasy poop (or steatorrhea): The stool changes color and becomes oily.
• Feeling like a lump in your abdomen: If the tumor is very large, it may even be felt.

What causes pancreatic cysts?

Pancreatic cysts are abnormal cell growths. Simply put, cells have a small change in their genes (a `genetic mutation`) and begin to divide abnormally. But researchers still don't know exactly why these genetic changes occur. They think they may be a combination of a genetic predisposition, inflammation of the pancreas, and other external factors, such as aging. A very small percentage of cysts are directly linked to certain hereditary conditions.

Some hereditary conditions that may be associated with pancreatic cysts include:

• `Von Hippel-Lindau disease`
• Polycystic kidney disease (large number of cysts in the kidneys)
• `Cystic fibrosis`

There are several risk factors that can contribute to the development of pancreatic tumors:

• Advancing age: The risk of developing pancreatic cysts increases as you get older. According to research, it is estimated that about a quarter (25%) of people in their 70s have them.
• Pancreatitis: Some types of tumors are associated with pancreatitis. Also, some types of tumors can cause pancreatitis.
• Family history: If someone in your family has had pancreatic cancer, or if you have a hereditary condition associated with pancreatic tumors, you are more likely to develop pancreatic tumors.

What are the possible complications of pancreatic tumors?

Complications are very rare, but if they do occur, they can include:

• Pancreatic duct obstruction: Some types of tumors called mucinous neoplasms can secrete a thick substance called mucin into the pancreatic duct. The duct can then swell, fill up, and eventually become blocked. This prevents the digestive enzymes produced by the pancreas from passing through the duct into your small intestine. The enzymes then back up into the pancreas, damaging it and causing pancreatitis. In the meantime, your digestive system doesn't get the enzymes it needs to digest food.
• Bile duct obstruction: If a large tumor presses on a bile duct, it can block the flow of bile. This is called cholestasis. This causes bile to build up, which can damage the bile duct and other organs connected to it (such as the liver). The bile can also mix with the blood, causing symptoms such as jaundice.
• Gastrointestinal obstruction: If a large tumor presses on your stomach or intestines, you may experience a variety of gastrointestinal symptoms, including abdominal pain, discomfort, bloating, constipation, and loss of appetite. In severe cases, food may stop moving through your digestive system altogether.
• Pancreatic cancer: As mentioned earlier, a very small percentage of tumors can develop into cancer. Most often, they are a type called adenocarcinoma. Pancreatic cancer is a type of cancer that tends to spread quite quickly. Therefore, it is very important to detect it as early as possible.

How do you diagnose a pancreatic tumor?

Doctors use the following tests to determine if a pancreatic cyst is present and, if so, what it looks like:

• Radiology: High-quality imaging techniques, such as CT scans or MRI scans, can clearly show pancreatic tumors. Some types of tumors can be identified on the scan. But others require further testing to determine exactly what type they are or to see if they contain cancer cells. In these cases, doctors may need to take a sample (a biopsy) of the tumor.
• Endoscopic Ultrasound / Fine Needle Aspiration (EUS-FNA): A procedure called Endoscopic ultrasound (EUS) allows a doctor to insert a very small, flexible endoscope (a tube with a camera and ultrasound device) through the mouth and into the stomach to reach a pancreatic tumor. The ultrasound will show exactly where the tumor is, and a thin needle (a fine needle) will be passed through the endoscope to remove a small sample of tissue and fluid from the tumor. This is called a fine needle aspiration (FNA). The sample is then analyzed in a laboratory.
• Fluid analysis: The fluid inside the cyst taken from the FNA is analyzed in a lab to see what type it is. This is also called cytology. They look for things like mucin. Mucin helps identify mucinous neoplasms. They also look for tumor markers like carcinoembryonic antigen (CEA). CEA is a protein found in the blood, and its levels can give some clues about the presence of cancer.

What are the treatments for pancreatic tumors?

The treatment of a pancreatic tumor depends on many factors, including the type of tumor, its size, whether it is symptomatic, and its risk of becoming cancerous. Here are the main treatment options:

• Surveillance: This means doing nothing, but constantly scanning and watching to see if the tumor changes.
• `Biopsy`: Taking a tissue sample and examining it to determine the exact nature of the tumor.
• Removal by surgery: If the tumor is considered dangerous or is causing problems, it is removed surgically.

Most cysts are treated with surveillance. This means you will have imaging scans from time to time (every 6 months, a year, or longer) to check on the cyst. If there are any suspicious changes, an EUS-FNA is done and the fluid is analyzed. If the results suggest cancer, your doctor may recommend removing it, depending on whether you are in a good condition to undergo surgery.

Do pancreatic tumors go away on their own?

Some benign tumors, especially small ones, can shrink on their own, or sometimes disappear completely. But the types called neoplastic, which can become cancerous, don't go away on their own. Most of the time, they continue to grow, but very slowly. Doctors monitor their growth. As long as they stay small, unless they get too big or change in a suspicious way, doctors don't do anything about them, they just watch.

How quickly do pancreatic tumors grow?

Different types of pancreatic tumors grow at different rates, but overall, they grow very slowly. If a tumor grows more than 3 millimeters (3 mm) per year, doctors are a little suspicious and pay more attention. If a tumor is being monitored for changes, it is checked every year, every two years, or sometimes every five years, depending on how quickly it is growing.

When should pancreatic cysts be removed?

Some pancreatic tumors may need to be removed if they cause complications or are suspected of being cancerous. But pancreatic surgery is a major procedure, with its own risks and side effects. That's why doctors carefully consider each tumor. They follow detailed medical guidelines to decide when to operate and remove a tumor.

Here are some things they consider:

• Size: Lumps larger than 3 centimeters (3 cm), or those that appear to be growing faster than normal, may need to be checked for cancer risk. Sometimes, even though large lumps are harmless, they may need to be removed because they cause discomfort or interfere with other organs.
• Type: Some types of tumors (e.g., MCNs, some IPMNs) have a higher risk of becoming cancerous. A doctor may recommend removing them early. Doctors will assess the risk of cancer and compare it to the risks of surgery, taking into account the person's general health.
• Visual signs: Sometimes, doctors see signs on scans that suggest a tumor may be cancerous or precancerous. For example, you may see that your pancreatic duct is enlarged, which could mean that you have a mucinous neoplasm that is secreting mucin into the duct. Or you may see that a tumor has solid parts, which could mean that it is not just a fluid-filled lump, but a solid tumor.
• Your condition: Some people have other health conditions (such as heart disease, diabetes) or significant factors, such as age, that make pancreatic surgery more risky for them. Doctors will weigh these risk factors against your cancer risk to make the best decision.

How is the surgery to remove a pancreatic tumor performed?

If your doctor recommends removing a tumor, it means you will have surgery. These surgeries are a bit more complicated. Sometimes a surgeon can carefully cut out just the tumor from your pancreas. But more often, a piece of your pancreas will also need to be removed. Depending on where the tumor is, it may also need to remove parts of other nearby organs (such as the spleen or part of the small intestine).

There are several types of surgeries that can be performed:

• Enucleation: This is the careful removal of a single tumor from the pancreas without damaging the surrounding healthy pancreatic tissue. If you have a single, small, benign tumor, it is in a palpable location, and it does not look like cancer, you may be eligible for this relatively minor surgery.
• Partial pancreatectomy: This involves removing the part of the pancreas that contains the tumor or tumors. Think of your pancreas as roughly shaped like a fish. It has a "head," a "body," and a "tail." A central pancreatectomy removes the middle part of the pancreas. A distal pancreatectomy removes the tail. Because the tail of the pancreas is very closely related to the spleen, a distal pancreatectomy often involves removing the spleen as well.
• Whipple procedure (also known as a pancreaticoduodenectomy): This is a slightly larger operation. The Whipple procedure removes the head of the pancreas and the pancreatic ducts. Cancerous tumors, such as mucinous neoplasms, are often found in this head. It is also a very busy junction where the upper part of your small intestine (duodenum), the pancreatic duct, and the common bile duct meet. If cancer is anywhere at this junction, it can spread to other branches, so the Whipple procedure removes not only the head of the pancreas, but also your duodenum, the common bile duct, and the gallbladder, which is attached to the other end of the common bile duct.
• Total pancreatectomy: This involves removing your entire pancreas . This may be necessary if you have a lot of tumors to remove, or if cancer appears to have spread throughout your pancreas. A total pancreatectomy may also remove nearby blood vessels and organs such as the spleen, gallbladder, duodenum, and lower part of the stomach.

What are the risks and side effects of pancreatic cyst surgery?

Surgery on your pancreas can affect its normal function. You need your pancreas to produce some important digestive enzymes and hormones, including insulin. Insulin is a hormone that controls blood sugar levels. If your pancreatectomy removes too many of the cells that make enzymes or insulin, you will need to take lifelong therapies to replace them. For example, you may need insulin injections or digestive enzyme pills.

Some pancreatectomy surgeries also remove or modify other organs. They can affect your digestive system, biliary system, and immune system. You may have difficulty digesting some foods and absorbing some nutrients (especially fat) afterward. If you have a splenectomy, your immune system may be slightly weakened, and you may get infections more often.

Specific side effects that may occur are:

• Diabetes: If the cells that produce insulin are destroyed.
• Exocrine pancreatic insufficiency: Insufficient digestive enzymes produced by the pancreas. This causes food to pass through the stomach without being digested.
• Fat malabsorption: Fatty foods are difficult to digest.
• Compromised immunity: If the spleen is removed.

Additional common risks of surgery are:

• Bleeding
• Infections
• Blood clots
• Anastomotic leak (leakage from the area where things like intestines are reconnected during surgery)

How serious is a pancreatic tumor?

Statistically, pancreatic tumors are less likely to cause serious problems. Doctors treat pancreatic tumors with extreme caution, because they want to avoid any risk. They will assess your tumor and decide what precautions to take. Although pancreatic surgery is a serious matter, most pancreatic tumors do not require surgery. So, don't panic when you find out you have a tumor.

What is the survival time after treatment for a pancreatic tumor?

This depends on the type of tumor and how far it has spread. If the tumor is removed before it becomes cancerous (precancerous) or when the cancer has not spread (noninvasive), the five-year survival rate after pancreatic cancer surgery is close to 100%. This means that the results are very good. For people with invasive cancer, the five-year survival rate after treatment is about 65%-75%. This also varies depending on the type of tumor and the stage of the cancer. The mortality rate (risk of dying from the surgery) for any major pancreatic surgery is usually about 4%.

What questions should I ask my doctor about my pancreatic cysts?

When you find out you have a pancreatic tumor, it's normal to have a lot of questions in your mind. You have the right to ask your doctor questions like:

• "What kind of tumor do I have?"
• "Is my risk of developing breast cancer low, medium, or high?"
• "How often should I get an imaging scan to check my tumors?"
• "Will my breasts get bigger? If so, how fast?"
• "Even though I have no symptoms, should I have this tumor removed?"
• "If I have to have surgery, what are the risks? What side effects will I experience?"

When you think about pancreatic cancer and surgery, even though the risk is very small, it can cause a lot of anxiety. But remember, most pancreatic tumors are nothing to be afraid of. Medical guidelines for monitoring, testing, and treating pancreatic tumors are designed to alleviate that unnecessary fear and protect you.

Abnormal growths (such as cysts) are common in many organs, especially as you get older. Pancreatic cysts are just one more organ to add to that list. The risk of these growths becoming cancerous is very small. If you remove a precancerous cyst right away, it won't have a chance to become cancerous.

The most important things you need to remember

Don't panic or be afraid when you're told you have a pancreatic cyst. Take a breath and talk openly with your doctor.

Most of the time, these are harmless, do not show symptoms, and are discovered by accident.

If a doctor says that, ask for details. Explain what type of tumor you have, how it might affect you, and what you need to do next.

Although there are types of cancer that can develop, there are now advanced methods to detect them and, if necessary, treat them at the right time. The most important thing is to follow the doctor's instructions carefully and have follow-up scans at the right time. Then you will not have to worry about this unnecessarily. Live a healthy life!
