The risk of developing pancreatic cancer is lower among nonsmokers, and people who maintain a healthy weight and limit their consumption of red or processed meat. Smokers' chances of developing the disease decrease if they stop smoking and almost return to that of the rest of the population after 20 years. Pancreatic cancer can be treated with surgery, radiotherapy, chemotherapy, palliative care, or a combination of these. Treatment options are partly based on the cancer stage. Surgery is the only treatment that can cure pancreatic adenocarcinoma, and may also be done to improve quality of life without the potential for cure. Pain management and medications to improve digestion are sometimes needed. Early palliative care is recommended even for those receiving treatment that aims for a cure.
