Generally, in this part of the world, where a majority of people do not have a practice of regularly visiting the hospital, to see a doctor for medical check-up, life-threatening health problems are often diagnosed very late. Different types of cancers fall under the category of diseases that doctor get to see late. Pancreatic cancer is one of such health problems.
The pancreas is a six-inch long, spongy, tube-shaped organ located in the back of the abdomen, behind the stomach. It has two major jobs in the body: to make digestive juices (called enzymes) that help break down food, and to make hormones, particularly insulin, which controls the body’s use of sugar and starch.
Pancreatic cancer happens when malignant (cancerous) cells grow, divide, and spread in the pancreas. Recently, a prominent oil and gas industry personality died after battling pancreatic cancer for some time. And overseas, some notable Americans like late Supreme Court Justice Ruth Bader Ginsburg, founder of Apple Computers Apple Steve Jobs, and actor Patrick Swayze (who acted with Demi Moore in popular movie, Ghost) also died of pancreatic cancer.
Symptoms
Like most other diseases, pancreatic cancer shows a number of warning signs, but most people miss them, particularly in the early stage of the disease.
But as the cancer grows and spreads, pain often develops in the upper abdomen and sometimes spreads to the back. The pain may worsen after you eat or lie down. Other symptoms may include jaundice, nausea, loss of appetite, weight loss, fatigue, weakness and depression.
Because doctors rarely find pancreatic cancer in its early stages when it’s easiest to treat, it’s one of the most deadly cancers. About 9 per cent of people with pancreatic cancer live at least 5 years after diagnosis. But the 5-year survival rate is much better (34 per cent) if it hasn’t spread past the pancreas. Know that survival rates can’t predict what will happen to any single person and may not reflect newer types of treatment.
Causes
Experts don’t know the exact cause of pancreatic cancer. Certain gene mutations can cause it. Other risk factors include smoking, age (it’s usually diagnosed in people older than 45), diabetes, chronic pancreatitis due to a genetic mutation, liver cirrhosis, family history of the condition, gender (it’s more common in men than women), obesity, certain chemicals, and race. (Africans have a slightly higher risk than whites. Medical experts do not yet know the reason.
Diagnosis
It can be hard to find this disease early on. A doctor may not see or feel a small tumor during a routine exam. To help make the diagnosis, you may get imaging tests such as an ultrasound or CT scan. These studies also help your doctor choose the most appropriate treatment. For a diagnosis, you’ll get a biopsy, in which your doctor uses a needle or does an operation to take a bit of tissue from the tumor for testing.
Surgery
Surgery to remove the tumor can cure the cancer if it hasn’t spread past the pancreas. Your surgeon will keep as much of the normal pancreas intact as possible. Unfortunately, with pancreatic cancer, the cancerous cells usually have spread past the pancreas by the time of diagnosis. If the tumor is too large to remove, a different type of surgery might be an option. The goal would be to help ease some of the symptoms and prevent certain problems related to the size of the cancerous mass.
Radiation therapy uses high-powered radiation to kill cancer cells. For pancreatic cancer, you’d likely get it five days a week for several weeks. This schedule helps to protect normal tissue by spreading out the total dose of radiation. Radiation is also being studied as a way to kill cancer cells that stay in the area after surgery. Radiation therapy can help relieve pain or digestive problems caused by large tumours.
Chemotherapy
Chemotherapy uses drugs to destroy cancer cells and stop them from growing or multiply- ing. It may involve one drug or a combination of drugs. You may get it by mouth or by injection. The drugs enter the bloodstream and travel through the body, making chemotherapy a good choice for cancer that has spread. You may also get it after surgery to kill any cancer cells left behind.
Targeted therapy
These medications attack specific parts of the cancer cells. Targeted therapies seem to have fewer side effects than chemotherapy and are less harmful to normal cells. Doctors can use a targeted therapy called erlotinib (Tarceva) along with chemo to treat advanced pancreatic cancer. Side effects can include a rash, diarrhea, appetite loss, and fatigue.
Palliative care
Palliative therapy is used to ease symptoms and manage pain in any stage of the disease. You can get it along with other medical treatments. The goal is to improve quality of life not just in the body, but in the mind and spirit. While palliative therapies are clearly appropriate at the very advanced stages of the disease, they also help when given along with other treatments that target the cancer.
Prevention of disease
While there’s no way to prevent all cases, you can take action against the risk factors you can control. A number of preventive tips include: Stop smoking, if you are smoker, reduce your weight to a healthy level and be a physically active person; eat a healthy diet, focusing especially on plant foods. Avoid alcohol or be ex- tremely moderate in consumption of alcoholic beverages. Heavy drinking may be a risk factor.
