Pancreatic Cancer: Experts Answer 10 Commonly Asked Questions
Can pancreatic cancer be prevented?A: Unfortunately, most pancreatic cancer cannot be prevented, but you can reduce your risk by maintaining a healthy weight, stopping smoking and limiting your alcohol intake. Other risk factors include chronic pancreatitis and family history. Occasionally, precancerous lesions can be identified and, if removed early, can prevent pancreatic cancer from developing.
What are the symptoms of pancreatic cancer?A: There are no specific symptoms for early-stage pancreatic cancer, but if you notice unintentional weight loss, jaundice (yellowing of the skin) and stomach pain, we recommend that you see your primary care physician.
What tests are available to detect pancreatic cancer?A: There are currently no simple tests for pancreatic cancer. Most cases are found when symptoms develop or an imaging study, such as a CT or MRI scan, is done for another reason. There is active research at Johns Hopkins that is aimed at developing a test for pancreatic cancer in the blood, urine and stool.
Why is pancreatic cancer usually found in the later stages?A: Pancreatic cancer usually does not cause symptoms, so approximately 50 percent of pancreatic cancers will not be identified until they have already metastasized (spread to other parts of the body).
Is there a direct correlation between breast cancer and pancreatic cancer?A: There is a relationship between BRCA mutations (breast and ovarian cancer) and pancreatic cancer. A BRCA mutation approximately doubles the lifetime risk of developing pancreatic cancer. Around 5 percent of people with pancreatic cancer have a BRCA mutation. However, breast cancer is very common, so not all patients with breast cancer are thought to have an increased risk of pancreatic cancer.
Is pancreatic cancer a genetic disease?
A: Pancreatic cancer can be genetic, but the vast majority of pancreatic cancer is sporadic. Many genes play a role in the growth of pancreatic cancer. The four major driver genes include KRAS, P53, P16 and SMAD4.
If you have a strong family history of pancreatic cancer, you should contact a genetic counseling and screening program. Familial pancreatic cancer is defined as having two or more first-degree relatives with pancreatic cancer. Johns Hopkins has a familial pancreatic cancer registry for surveillance of such patients.
