Pancreatic cancer is a type of cancer caused by abnormal growth and uncontrolled proliferation of pancreatic cells. The pancreas is an important organ that secretes digestive enzymes and hormones.
Pancreatic cancer is usually caused by cells called adenocarcinomas, and this type of cancer occurs in the lining of the pancreas. In rare cases, other types can also occur, originating from the hormone-producing cells of the pancreas.

Role and Location of the Pancreas
The pancreas is an important organ in the digestive system. It consists of three parts: head, body and tail. Digestive enzymes (such as amylase, lipase and trypsin) are produced by the pancreas and help digest food in the small intestine. In addition, pancreatic hormones (such as insulin and glucagon) play an important role in regulating blood sugar.
Effects of Pancreatic Cancer
Pancreatic cancer disrupts the normal functions of the pancreas. Cancer cells can affect the structures and functions of the pancreas, reducing or blocking the production of digestive enzymes. This can disrupt the functioning of the digestive system, causing digestive problems, weight loss and nutritional problems. In addition, pancreatic cancer can lead to hormone imbalances, especially if insulin-producing cells are affected, which can lead to problems with blood sugar control.
In advanced stages, pancreatic cancer can spread to other parts of the body by metastasizing to surrounding tissues or distant organs. In this case, the spread of cancer to different parts of the body may cause different symptoms and treatment options to be considered.
Pancreatic cancer is often asymptomatic in the early stages and can be difficult to diagnose. For this reason, it is often diagnosed in advanced stages when the cancer has progressed and symptoms appear.
Pancreatic cancer is often a challenging disease in terms of treatment options and prognosis. The treatment plan is determined depending on the stage of the cancer, general health and other factors.
Types of Pancreatic Cancer
What is Adenocarcinoma?
Adenocarcinoma, the most common type of pancreatic cancer, is made up of cancer cells that originate from the glands of the pancreas. This type of cancer arises from cells in the outer part of the pancreas. Adenocarcinoma is usually aggressive and can progress without symptoms in the early stages. Usually, when adenocarcinoma is diagnosed, the cancer is usually in advanced stages.
Pancreatic Benign Tumors and Symptoms
Benign tumors in the pancreas are abnormal cell growths that are not associated with cancer. Such tumors are usually different from cancerous tumors because they do not spread throughout the body or metastasize to other tissues. Benign pancreatic tumors can often cause the following symptoms: abdominal pain, weight loss, digestive problems and rarely jaundice.
Mass Formation and Spread of Pancreatic Cancer
In pancreatic cancer, mass formation begins when cells multiply abnormally and come together to form a tumor. This mass may initially be confined within the pancreas. However, as the cancer progresses, this mass may spread to other parts of the pancreas or spread to surrounding tissues. The process by which masses spread determines the stage of the cancer and affects treatment options.
The types of pancreatic cancer and the processes of mass formation play an important role in the progression of the disease and treatment options. For diagnosis and treatment, it is crucial to accurately determine the type of cancer and the degree of spread.
Pancreatic Cancer Symptoms
Early Signs of Pancreatic Cancer
In the early stages, symptoms of pancreatic cancer can often be vague or mild. These symptoms may include:
Abdominal Pain and Discomfort:
Persistent or intermittent pain or discomfort in the abdomen.
Fatigue and Weakness:
Sudden or persistent fatigue, weakness or lack of energy.
Loss of Appetite and Weight Loss:
Sudden loss of appetite, decreased interest in food and involuntary weight loss.
Nausea and Vomiting:
Feeling nauseous and sometimes vomiting, especially after eating.
Digestive Problems:
A tendency to experience digestive problems such as constipation or diarrhea.
Symptoms of Advanced Pancreatic Cancer
As pancreatic cancer progresses, symptoms can become more pronounced. Advanced stage symptoms include:
Jaundice:
Symptoms of jaundice, such as yellowing of the skin and eyes (icterus), can be caused by blocked bile ducts.
Abdominal distension:
A feeling of swelling, discomfort or pressure in the abdomen.
Pain and Severe Discomfort:
Pain and discomfort in the abdomen may increase, especially as the cancer progresses.
Jaundice and Change in Urine Color:
Dark urine and light stools are signs of jaundice.
High Sugar Levels:
High blood sugar levels associated with the hormone-producing cells of the pancreas being affected.
Back Pain Pancreatic Cancer
Pancreatic cancer can cause some symptoms, including back pain. Back pain in particular can be one of the symptoms associated with pancreatic cancer. There may also be symptoms such as digestive problems, yellowing of the skin and constant fatigue.
Stages of Pancreatic Cancer
Pancreatic cancer stages are used to determine how far the disease has progressed and how far it has spread in the body. Staging is important in determining treatment options and assessing the prognosis of the disease. It is usually defined in terms of the following stages:
Stage 0 Pancreatic Cancer (Precancerous):
Cancer cells are only found in a specific area within the pancreas. At this stage, cancer cells have not spread to other tissues or organs.
Stage 1 Pancreatic Cancer:
The cancer is confined to a specific area of the pancreas and has not spread to nearby tissues.
Stage 2 Pancreatic Cancer:
The cancer may have spread to a larger area of the pancreas and may have spread to some neighboring organs or tissues.
Stage 3 Pancreatic Cancer:
The cancer may have spread to the large vessels around the pancreas or to nearby organs. However, it has not yet spread to distant organs (distant metastases).
Stage 4 Pancreatic Cancer:
At this stage, the cancer has spread beyond the pancreas and metastasized to surrounding tissues, other organs or distant sites (such as the liver, lung, brain).
Each stage plays an important role in determining the treatment plan and prognosis of the disease. Pancreatic cancer diagnosed in the early stages usually offers a better chance of cure, while treatment options may be more limited for cancers diagnosed in advanced stages.
Therefore, once the stage of the cancer is determined, treatment strategies and the patient's prognosis can be better understood.
Pancreatic Cancer Diagnosis
Diagnostic Methods and Tests in Pancreatic Cancer
Pancreatic cancer is usually diagnosed with the following methods:
Pancreatic cancer Imaging Tests:
Imaging tests such as computed tomography (CT) scans, magnetic resonance imaging (MRI), ultrasonography and positron emission tomography (PET) can help show abnormalities and masses in the pancreas.
Pancreatic cancer Blood Tests:
Blood tests can help determine the presence of cancer by measuring levels of cancer markers (such as CA 19-9). However, these markers alone are not enough to diagnose pancreatic cancer.
Pancreatic cancer Endoscopic Ultrasonography (EUS):
This method uses ultrasound to observe problems such as pancreatic cancer in more detail. This endoscopic test can provide important information about the size and location of cancerous lesions and their relationship with nearby tissues.
Pancreatic cancer Biopsy:
A biopsy is often necessary to confirm the diagnosis of pancreatic cancer. This means taking a sample of abnormal tissue and examining it under a microscope. The biopsy can usually be performed under endoscopic ultrasonography (EUS) or CT guidance.
Pancreatic Cancer Staging
Staging of pancreatic cancer is done to determine how far the disease has progressed and spread. Staging is usually based on the following factors:
Pancreatic cancer Tumor size:
The size of the cancerous tumor and the areas to which it has spread are assessed.
Pancreatic cancer Nodules and Lymph Nodes:
The lymph nodes around the pancreas are checked for the presence of cancer cells.
Pancreatic cancer Metastases:
This assesses whether the cancer has spread to other parts of the body (distant organs).
Pancreatic Cancer Treatment
Surgical Intervention in Pancreatic Cancer: Whipple Surgery and Open Pancreas Surgery
Whipple Surgery (Pancreaticoduodenectomy):
In this surgery, the head of the pancreas, duodenum, gallbladder, bile ducts and sometimes part of the stomach are removed. This surgery is performed to remove tumors located at the head of the pancreas or in the ampulla (duodenal region).
Open Pancreas Surgery (Total Pancreatectomy):
In this surgery, the entire pancreas can be removed, including the gallbladder and sometimes nearby lymph nodes. It is a rare surgical procedure and is usually preferred when the cancer has spread to a large area of the pancreas.
Radiotherapy and Chemotherapy for Pancreatic Cancer
Pancreatic Cancer Radiotherapy:
A treatment that uses high-energy rays to kill cancer cells or control their growth. In pancreatic cancer, radiotherapy can be used to shrink the tumor before surgery, for postoperative treatment or to control symptoms.
Pancreatic Cancer Chemotherapy:
A form of treatment that aims to kill cancer cells or control their growth using drugs. In pancreatic cancer, chemotherapy can be used for pre- or post-operative treatment, to control the spread of cancer or to relieve symptoms.
Targeted Therapies for Pancreatic Cancer
Pancreatic Cancer Targeted Drug Therapies:
Drugs that target specific cancer cells can stop the growth of cancer cells or kill them. For example, drugs that block cell growth signals or kill cells can be used as targeted therapies.
Pancreatic Cancer Immunotherapy:
This treatment method involves drugs that stimulate or strengthen the body's immune system to fight against cancer cells. In pancreatic cancer, immunotherapy can help the immune system fight the cancer.
These treatment methods can be applied depending on the stage of pancreatic cancer, its spread and the patient's general health. The treatment plan is usually tailored to the patient's condition by a specialist oncologist.
Pancreatic Cancer Recovery Process
Symptoms and Process of Recovery in Pancreatic Cancer
Pancreatic cancer treatment may differ depending on the person's general health, the stage of the cancer and the treatment methods used. Some symptoms and the process of recovery may include:
Pancreatic Cancer Pain Management:
Pain may be experienced frequently after surgery or during the treatment process. Pain can be controlled with medications recommended by the doctor.
Pancreatic Cancer Wound Healing:
The wound healing process in the postoperative period is important. Wound care should be done in accordance with the doctor's recommendations to accelerate the healing process and prevent complications.
Pancreatic Cancer Energy Level and Fatigue:
The treatment process can often cause fatigue and loss of energy. Rest, regular exercise and a balanced diet can increase energy levels during the healing process.
Care Recommendations and Nutrition in Pancreatic Cancer
Pancreatic Cancer Balanced Nutrition:
Nutrition plays an important role in the treatment of pancreatic cancer. Food can be difficult to digest, so light, easily digestible and nutritious foods should be preferred.
Pancreatic Cancer Fluid Consumption:
Fluid intake is important. Consuming water, fruit juice or juicy fruits can help to maintain the body's fluid balance.
Pancreatic Cancer Protein and Energy Needs:
High-calorie and protein foods recommended by the doctor or dietitian should be consumed to meet protein and energy needs.
Rehabilitation After Pancreatic Cancer Surgery
Pancreatic Cancer Physical Therapy and Exercise:
Physical therapy and exercises are important in the post-operative rehabilitation process to restore muscle strength, increase mobility and support the healing process.
Pancreatic Cancer Psychological Support:
Pancreatic cancer treatment and recovery can be emotionally challenging. Receiving psychological support can support the patient's mental health.
Pancreatic Cancer Follow-up Examinations:
Regular medical check-ups after treatment are important to monitor the healing process and to detect possible complications early.
