Pancreatic Cancer
Causes, Symptoms & Treatment Options
Pancreatic cancer is a disease that starts in the pancreas, an organ in the belly. It is hard to detect early because symptoms usually do not appear until it is in a later stage. This can make treatment more difficult. Knowing what causes it, recognizing early signs, and learning about treatments can help people stay aware and take action. Let’s explore what leads to pancreatic cancer, its symptoms, and ways to prevent it.
Introduction to Pancreatic Cancer
Pancreatic cancer starts in the pancreas, an organ behind the stomach that helps with digestion and blood sugar control. The most common type, pancreatic ductal adenocarcinoma, forms in the ducts that carry digestive enzymes. This cancer can spread quickly, so finding it early is important for better treatment options.
In the past, pancreatic cancer was not as common as it is today. However, changes in lifestyle, diet, and longer life spans have led to an increase in cases. Scientists first discovered this cancer in the 18th century, but major improvements in diagnosis and treatment have only come in recent years. Even with advancements, pancreatic cancer is still one of the deadliest cancers, making awareness and early detection essential.

What Causes Pancreatic Cancer?
Pancreatic cancer happens when cells in the pancreas start growing out of control. Different things can raise the risk of this disease, including inherited genes, lifestyle habits, and certain health problems.
- Genetic Mutations & Family History
Some people are more likely to get pancreatic cancer because of changes in their genes that run in families.
⦿ Inherited genetic mutations – Some people are born with gene changes that can make cells grow abnormally, leading to cancer.
⦿ Family history – If close relatives have had pancreatic cancer, there may be a higher chance of getting it.
⦿ BRCA1 & BRCA2 gene mutations – These gene changes, known for raising the risk of breast cancer and ovarian cancer, can also increase the risk of pancreatic cancer.

Early Signs & Symptoms of Pancreatic Cancer
Pancreatic cancer is hard to detect early because symptoms may be mild or seem like other health problems. But there are some warning signs to watch for.
- Common Symptoms
- Jaundice & Skin Changes
If pancreatic cancer blocks the bile ducts, it can cause changes in the skin and digestive system.
Dark urine and light-colored stools
When bile flow is blocked, urine may become darker, and stools may look pale.
- Other Warning Signs
New diabetes diagnosis in older adults
Developing diabetes suddenly, especially after age 50, could be a sign.

How Do Doctors Diagnose Pancreatic Cancer?
Doctors use different tests to find out if a person has pancreatic cancer. These tests help them see if there is a tumor, how big it is, and if it has spread to other parts of the body.
- Imaging Tests & Scans
These tests take pictures of the inside of the body to look for tumors.
⦿ CT scan and MRI – These scans create clear images of the pancreas and nearby areas to check for cancer.
⦿ Endoscopic ultrasound (EUS) – A tiny ultrasound device is placed inside the body to get a closer look at the pancreas.
⦿ PET scan – This scan helps find cancer in other parts of the body by showing where cancer cells might be growing.

⦿ PET scan – This scan helps find cancer in other parts of the body by showing where cancer cells might be growing.
- Blood Tests & Biomarkers
Blood tests can give doctors clues about pancreatic cancer.
⦿ CA 19-9 tumor marker test – This test looks for a special protein in the blood that may be high in people with pancreatic cancer.
⦿ Liver function tests – These tests check if the cancer is blocking the bile ducts, which can cause liver problems.
⦿ Genetic testing – This test looks for inherited gene changes that might increase the risk of pancreatic cancer.

⦿ Genetic testing – This test looks for inherited gene changes that might increase the risk of pancreatic cancer.
- Biopsy & Tissue Testing
A biopsy is when doctors take a small sample of tissue to check for cancer.
⦿ Fine-needle aspiration (FNA) biopsy – A thin needle is used to take a small piece of the pancreas for testing.
⦿ Tissue sampling – The sample is studied under a microscope to see if it has cancer cells.
⦿ Pathology testing – Doctors use this information to help decide the best treatment.

Stages of Pancreatic Cancer
Doctors divide pancreatic cancer into different stages based on how much it has spread.
- Stage 1 – Cancer in the Pancreas Only
⦿ The cancer is small and only in the pancreas.
⦿ This is the best stage for surgery to remove it.
⦿ This is the best stage for surgery to remove it.
- Stage 2 – Cancer Has Spread Nearby
⦿ The cancer has reached nearby lymph nodes but not other organs.
⦿ Treatment may include surgery, chemotherapy, or radiation.
⦿ Treatment may include surgery, chemotherapy, or radiation.
- Stage 3 – Cancer Has Grown Larger
⦿ The cancer has spread to major blood vessels.
⦿ Surgery is usually not possible, and chemotherapy is the main treatment.

- Stage 4 – Cancer Has Spread to Other Organs
Treatment Options for Pancreatic Cancer
Doctors use different treatments to fight pancreatic cancer. The best treatment depends on how far the cancer has spread and the person’s overall health.
Surgery
If the cancer is caught early, doctors may remove it with surgery.
⦿ Whipple procedure – Removes the head of the pancreas, part of the stomach, small intestine, and bile duct.
⦿ Distal and total pancreatectomy – A distal pancreatectomy removes part of the pancreas, while a total pancreatectomy removes the whole pancreas.
⦿ Who can have surgery? – Surgery is an option if the cancer hasn’t spread to major blood vessels or other parts of the body.
Chemotherapy
Chemotherapy uses medicine to destroy cancer cells or slow their growth.
⦿ Common chemotherapy drugs – Medicines like Gemcitabine and FOLFIRINOX help shrink tumors and slow cancer spread.
⦿ Dealing with side effects – Chemotherapy can cause nausea, tiredness, and hair loss, but doctors can help manage these symptoms.

⦿ Dealing with side effects – Chemotherapy can cause nausea, tiredness, and hair loss, but doctors can help manage these symptoms.
Targeted Therapy
⦿ Targeted therapy uses specific drugs to attack cancer cells directly, often by interfering with their growth signals.
⦿ Immunotherapy and targeted drugs – Some treatments help the body’s immune system fight cancer or directly attack specific cancer cell pathways.
Radiation & Supportive Care
Radiation and other treatments can help shrink tumors and ease symptoms.
⦿ Radiation therapy – Uses high-energy rays to shrink tumors. It may be given before or after surgery.
⦿ Pain relief and support – Medications and therapies help manage pain and make the person more comfortable.
⦿ Quality of life care – For advanced cancer, palliative care focuses on comfort and symptom control.
