A centimeter is roughly equal to the width of a standard pen or pencil. The tumor stage helps the doctor develop the best treatment plan for each patient. Specific tumor stage information is listed below. Tis: Refers to carcinoma in situ, which is very early cancer that has not spread. T1: The tumor is in the pancreas only, and it is 2 centimeters cm or smaller in size. This stage may be further divided into T1a, T1b, and T1c based on the size of the tumor. T2: The tumor is in the pancreas only, and it is larger than 2 cm but not larger than 4 cm.
T3: The tumor is larger than 4 cm and extends beyond the pancreas. It does not involve the major arteries or veins near the pancreas. T4: The tumor extends beyond the pancreas into major arteries or veins near the pancreas. A T4 tumor cannot be completely removed with surgery.
The "N" in the TNM staging system is for lymph nodes. These small, bean-shaped organs located throughout the body help fight infection and disease as part of the body's immune system. In pancreatic cancer, regional lymph nodes are those lymph nodes near the pancreas and distant lymph nodes are those lymph nodes in other parts of the body.
The "M" in the TNM system describes whether the cancer has spread to other parts of the body, called distant metastasis. M1: Cancer has spread to another part of the body, including distant lymph nodes.
Pancreatic cancer most commonly spreads to the liver, the lining of the abdominal cavity called the peritoneum, and the lungs. Stage 0: Refers to cancer in situ, in which the cancer has not yet grown outside the duct in which it started Tis, N0, M0. Stage IA: The tumor is 2 cm or smaller in the pancreas. It has not spread to lymph nodes or other parts of the body T1, N0, M0. Stage IB: A tumor larger than 2 cm is in the pancreas.
It has not spread to lymph nodes or other parts of the body T2, N0, M0. Stage IIA: The tumor is larger than 4 cm and extends beyond the pancreas.
It has not spread to nearby arteries, veins, lymph nodes, or other parts of the body T3, N0, M0. Stage IIB: A tumor of any size has not spread to nearby arteries or veins. It has spread to 1 to 3 regional lymph nodes but not to other parts of the body T1, T2, or T3; N1; M0.
A tumor of any size that has spread to 4 or more regional lymph nodes but not to nearby arteries, veins, or other parts of the body T1, T2, or T3, N2, M0. A tumor that has spread to nearby arteries and veins and may have spread to regional lymph nodes. It has not spread to other parts of the body T4, any N, M0. Recurrent: Recurrent cancer is cancer that has come back after treatment. If the cancer does return, there will be another round of tests to learn about the extent of the recurrence.
These tests and scans are often similar to those during the original diagnosis. The next section in this guide is Types of Treatment. Use the menu to choose a different section to read in this guide. Finally, images are taken of the ducts. A growing tumor may press on nerves in your abdomen, causing pain that can become severe.
Pain medications can help you feel more comfortable. Treatments, such as radiation and chemotherapy, might help slow tumor growth and provide some pain relief. In severe cases, your doctor might recommend a procedure to inject alcohol into the nerves that control pain in your abdomen celiac plexus block.
This procedure stops the nerves from sending pain signals to your brain. Bowel obstruction. Pancreatic cancer that grows into or presses on the first part of the small intestine duodenum can block the flow of digested food from your stomach into your intestines. Your doctor may recommend that a tube stent be placed in your small intestine to hold it open. In some situations, it might help to have surgery to place a temporary feeding tube or to attach your stomach to a lower point in your intestines that isn't blocked by cancer.
Consider meeting with a genetic counselor if you have a family history of pancreatic cancer. He or she can review your family health history with you and determine whether you might benefit from a genetic test to understand your risk of pancreatic cancer or other cancers.

Then, the doctor gets a sample of the tumor tissue to figure out the exact diagnosis. The pancreas is located deep in the abdomen, so doctors usually cannot see or feel the tumor during a physical exam. Also, pancreatic cancer symptoms are not always obvious and usually develop over time.
Doctors may use several tests to make a diagnosis. But, there is no standard test to diagnose pancreatic cancer.
This makes diagnosis even more complicated. Patients may get standard approved treatments or take part in clinical trials. Standard treatments are surgery, chemotherapy and radiation. Clinical trials study new treatments. The Pancreatic Cancer Action Network strongly recommends clinical trials at diagnosis and during every treatment decision.
Surgery offers the best chance of controlling pancreatic cancer for a long time. But, most patients are diagnosed at later stages and are not eligible for surgery. Tests to find pancreatic cancer in the earliest stages are urgently needed. As early detection study continues and as technology gets better, researchers predict that we will make progress toward finding the disease earlier.
Another challenge is that pancreatic tumors are surrounded by a dense tissue layer, called the stroma. This makes it difficult for treatment to reach the tumor. Researchers are studying ways to get treatment through the stroma to make it more effective.
Also, some cancers have been successfully treated with targeted therapies which block specific mutations. But, these drugs have not been developed specifically for pancreatic cancer yet.
Biomarker testing of tumor tissue and genetic testing for inherited mutations tell you about your unique biology. Results may align with targeted treatments that work well in other cancer types. As more studies are done, more targeted treatments will be developed and approved for pancreatic cancer patients who have specific genetic changes.
