What is the #1 cause of pancreatic cancer?

Cigarette smoking (responsible for about 25% of pancreatic cancers) Alcohol abuse. Regular consumption of high dietary fats. Obesity (obese people are about 20% more likely to develop pancreatic cancer than non-obese people)

What chemicals can cause pancreatic cancer?

Exposure to certain chemicals such as pesticides, benzene, certain dyes, and petrochemicals may increase the risk of developing pancreatic cancer.

What was your first symptom of pancreatic cancer?

When symptoms of a pancreatic tumor first appear, they most commonly include jaundice, or a yellowing of the skin and the whites of the eyes, which is caused by an excess of bilirubin—a dark, yellow-brown substance made by the liver. Sudden weight loss is also a common early warning sign of pancreatic cancer.

What is the most common mutation in pancreatic cancer?

BRCA1/2 are the most common genes mutated in familial pancreatic cancers, and mutations in BRCA1/2 increase the risk of pancreatic cancer susceptibility [143]. Germline BRCA1/2 mutations occur in 4%–7% of all pancreatic cancers [144].

How does pancreatic cancer develop?

Pancreatic cancer occurs when cells in your pancreas develop changes (mutations) in their DNA. A cell’s DNA contains the instructions that tell a cell what to do. These mutations tell the cells to grow uncontrollably and to continue living after normal cells would die. These accumulating cells can form a tumor.

How is pancreatic cancer detected?

CT scans are often used to diagnose pancreatic cancer because they can show the pancreas fairly clearly. They can also help show if cancer has spread to organs near the pancreas, as well as to lymph nodes and distant organs. A CT scan can help determine if surgery might be a good treatment option.

What causes a person to have pancreatic cancer?

Genes that help keep cell division under control or cause cells to die at the right time are called tumor suppressor genes. Cancers can be caused by DNA changes that turn on oncogenes or turn off tumor suppressor genes. Some people inherit gene changes from their parents that raise their risk of pancreatic cancer.

What kind of mutations are found in pancreatic cancer?

Acquired gene mutations. But many pancreatic cancers also have changes in genes such as KRAS, BRAF, and DPC4 ( SMAD4 ), which are not part of inherited syndromes. Other gene changes can also be found in pancreatic cancers, although often it’s not clear what has caused these changes.

What causes nausea and vomiting with pancreatic cancer?

Nausea and vomiting caused by cancer treatments or a tumor pressing on your stomach may make it difficult to eat. Or your body may have difficulty processing nutrients from food because your pancreas isn’t making enough digestive juices. Jaundice.

Can a sporadic case of pancreatic cancer be inherited?

Some of the DNA changes often seen in sporadic (non-inherited) cases of pancreatic cancer are the same as those seen in inherited cases, while others are different. For example, many sporadic cases of exocrine pancreatic cancer have changes in the p16 and TP53 genes, which can also be seen in some genetic syndromes.
