Pancreatic cancer has been a subject of continuous study and research as scientists are digging in for the exact causes of the disease. The basic reason for this cancer as understood by the scientists and researchers is the destruction of DNA which is also known as mutation commonly. This is inherited by the parents but there are things to avoid which can cause such mutation in any individual. Not necessarily, everyone who has inherited this gene from parents will suffer from pancreatic cancer.
There are various risk factors that cause this cancer and the most common one is smoking. According to the scientists, on an average every one in five cases is due to smoking. Due to smoking, people are at the risk of getting cancer at very early age proving that smoking is the leading cause of this type of cancer. Age is the second factor that can cause pancreatic cancer as the chances of getting the disease surges by 80% with increasing age. Most commonly this cancer hits the body between the age of 60 and 80 years.
Pancreatic cancer is more common in males as compared to the females. It is common amongst men because on an average men smoke more than women and hence stand a higher risk of getting cancer. There have been different studies based on the religion, geography, obesity and so on to identify the exact causes of cancer and provide better treatment.
Pancreatic cancer is a disease that takes several years to develop and takes number of steps to develop. DNA changes in such situation effects KRAS oncogene which in turn hampers the growth of cell. Surgery to treat the cancer is a lengthy and time taking process that is complex even for a good pancreatic cancer surgeon and tiring for the patient. Laparoscopic operation for the pancreatic cancer is the preferred method of treatment by the surgeons where there are few incisions made in the belly instead of a large cut. Recovery in this type of surgery is faster compared to other treatments but still the process is complicated.
Various radiation therapies are also being developed such as intra-operative therapy, proton beam radiation and so on. These radiation therapies are being developed to treat exocrine pancreas cancer. Targeted therapies are another field where researches are being done and focus is on finding new solutions and better ways of treating the cancer.
