How does a person get pancreatic cancer?
Most of the cancers have no early signs. In the case of pancreatic cancer, It is always difficult to detect this type of cancer early. Uncontrollable growth of cells in your pancreas that develop mutations in their DNA. This results in an uncontrolable growth of cells.

Pancreatic cancer occurs when cells in your pancreas develop mutations in their DNA. These mutations cause cells to grow uncontrollably and to continue living after normal cells would die. These accumulating cells can form a tumor. Untreated pancreatic cancer spreads to nearby organs and blood vessels.

How pancreatic cancer forms
Pancreatic cancer occurs when cells in your pancreas develop mutations in their DNA. These mutations cause cells to grow uncontrollably and to continue living after normal cells would die. These accumulating cells can form a tumor. Untreated pancreatic cancer spreads to nearby organs and blood vessels.
Most pancreatic cancer begins in the cells that line the ducts of the pancreas. This type of cancer is called pancreatic adenocarcinoma or pancreatic exocrine cancer. Rarely, cancer can form in the hormone-producing cells or the neuroendocrine cells of the pancreas. These types of cancer are called islet cell tumors, pancreatic endocrine cancer and pancreatic neuroendocrine tumors.
RISK FACTORS
Factors that may increase your risk of pancreatic cancer include:
• Chronic inflammation of the pancreas (pancreatitis)
• Diabetes
• Family history of genetic syndromes that can increase cancer risk, including a BRCA2 gene mutation, Lynch syndrome and familial atypical mole-malignant melanoma (FAMMM) syndrome
• Family history of pancreatic cancer
• Smoking
• Obesity
• Older age, as most people are diagnosed after age 65
A large study demonstrated that the combination of smoking, long-standing diabetes and a poor diet increases the risk of pancreatic cancer beyond the risk of any one of these factors alone.」 (emphases added)

「Pancreatic Cancer Causes Still Unknown
Pancreatic cancer develops when a cell in the pancreas acquires damage to its DNA that causes it to behave and multiply abnormally. A single cancer cell grows and divides rapidly, becoming a tumor that does not respect normal boundaries in the body. Eventually, cells from the tumor travel elsewhere in the body (metastasize) through the blood or lymphatic system.
No one knows exactly how the process of DNA damage leading to pancreatic cancer occurs. Analyzing pancreatic cancers removed by surgery shows certain mutations that occur in nearly all cases, and others that vary between people.
Some of these mutations occur randomly. Others occur in response to things we do or experience in the environment. Some mutations may be inherited. When enough mutations accumulate, a cell becomes malignant and a tumor begins to grow.」

It’s not clear what causes pancreatic cancer in most cases. Factors, such as smoking, that increase your risk of developing the disease.
Pancreatic cancer occurs when cells in your pancreas develop mutations in their DNA. 2 types of mutation are found : 1.Inherited gene mutations
2.Acquired gene mutations
These mutations cause cells to grow uncontrollably and to continue living after normal cells would die. These accumulating cells can form a tumor. Untreated pancreatic cancer spreads to nearby organs and blood vessels.
Most pancreatic cancer begins in the cells that line the ducts of the pancreas. This type of cancer is called pancreatic adenocarcinoma or pancreatic exocrine cancer.
