Pancreatic cancer is a malignant tumor that develops from the epithelium of various parts of the pancreas.1. For a long time, the disease can proceed without symptoms at all. On the other hand, the signs of the disease may be similar to those of other health problems.
“Often, the first symptoms of pancreatic cancer appear already in the later stages, when the tumor has grown, compresses neighboring organs and ducts, which leads to intoxication of the body with decay products,” notes Oleg Zarubenkov, PhD, oncologist of the highest category. – A malignant neoplasm can be found in the head (according to various sources, 50-75% of cases), body or tail of the pancreas. In 25-30% of cases, the entire pancreas is affected.
Cancer of the head of the pancreas is often manifested by pain in the upper abdomen, aching back pain, weight loss2. People rarely pay attention to such symptoms at first, and by the time the patient sees a doctor, the cancer is usually incurable.
The incidence of pancreatic cancer is steadily increasing from year to year. Unfortunately, effective methods of treatment that could significantly extend the life of patients and improve its quality, alas, have not yet been invented.
What to do? First of all, pay attention to risk factors. These include: alcohol abuse, chronic pancreatitis, diabetes mellitus, smoking, obesity, physical inactivity3.
Also, pancreatic cancer is associated with the following factors: pancreatic cysts and adenomas (considered precancerous conditions), age over 60-65 years, cirrhosis of the liver, cholelithiasis, heredity (for example, cases of adenocarcinoma of the pancreas in relatives, and other factors).
Rejection of bad habits
Smoking is harmful not only to the lungs, but is also the direct cause of the development of 30-35% of all malignant neoplasms, including pancreatic cancer.4. And if in most cases the disease occurs in older people, then smokers can develop cancer earlier.5.
In itself, alcohol consumption, according to the results of various studies, does not have a significant effect on the development of pancreatic cancer. But, for example, alcoholic pancreatitis and a combination of bad habits (smoking + alcohol consumption) are considered risk factors.5.
Diet
There is evidence that eating large amounts of animal fat contributes to the mutation of the KRAS genes, which increases the risk of developing pancreatic and colon cancer. Reducing the calorie content of food has the opposite effect.6.
Many experts recommend adding more vegetables, fruits and berries to the diet, as well as foods rich in fiber.7. The most useful plant foods are citrus fruits, blueberries, black currants, raspberries, onions, garlic, cruciferous and leafy vegetables. But fruits rich in fructose (apples, pears, melons), it is better to consume less. As well as the beloved by many potatoes with sausages or cutlets from the store. Vegetables and fruits are useful to eat fresh (including after defrosting). Carrots, pumpkin, tomatoes, bell peppers are best eaten boiled or stewed. But fried or canned fruits and vegetables are harmful, and not only for the pancreas, but also for all digestive organs.
The researchers also conducted a study in which patients at risk for PCa were included in the diet of rosemary, turmeric, red pepper, as well as some nutrients, such as selenium and zinc. The result of the study: for 3 years, the participants of the experiment did not show a clinical picture of pancreatic cancer, and tumor markers were normal7.
In order to prevent cancer, you can try to stick to the Mediterranean diet, which involves a large number of vegetables and fruits, whole grains, olive oil and fish.
However, as many experts say, the issue of dietary prevention has not been sufficiently studied, and no one can say exactly what to eat and what not to avoid getting cancer. In other words, diet is not a guarantee.
Physical activity
According to some studies, an adequate increase in physical activity helps to reduce the risk of developing pancreatic cancer (and also cancer of the liver, stomach, colon)8.
It is not necessary to dedicate sports every evening and weekend – just 30 minutes of moderate activity is enough, whether it’s half an hour in the pool or walking from work to home at a brisk pace.
Light physical activity, such as regular gymnastics and walking in the fresh air, is also recommended by many doctors for patients with pancreatic cancer. It helps to maintain good health, appetite and mood, as well as reduce the side effects of chemotherapy and radiation therapy.
Weight Control
Overweight and obesity increase the risk of getting cancer. It is the second most common cause of cancer4. Including when it comes to pancreatic cancer. People with a body mass index greater than 30 are at high risk9.
At the same time, it must be remembered that a sudden decrease in body weight for no apparent reason is a direct reason to consult a doctor. This may be a sign of pancreatic cancer.
Medical supervision
Scientists consider chronic pancreatitis not just a risk factor for the development of pancreatic cancer, but even call this pathology a precancerous condition. With a long course of pancreatitis, the risk of developing cancer increases 20 times, and if chronic pancreatitis is hereditary, then 60 (!) Times1. Therefore, it is necessary to regularly see a doctor and strictly follow all his recommendations.
The same goes for diabetes – people with this disease are also at risk for PCa. For example, patients of the “golden age” with newly diagnosed diabetes mellitus have an 8-fold increased risk of developing pancreatic cancer.10.
By the way, after the treatment of pancreatic cancer, the risk of relapse is not excluded. Therefore, doctors recommend seeing a doctor every 12-16 weeks during the first two years after surgery and every six months thereafter.3.
Examination typically includes: Abdominal ultrasound, abdominal CT or MRI, pelvic ultrasound (for women), chest x-ray, complete blood count and biochemistry, and cancer antigen levels (fetal and CA). 19-9)11.
genetic screening
About 10% of cases of pancreatic cancer are due to heredity3. Therefore, many experts believe that identifying a predisposition to the development of oncology is a step ahead of the curve, with which you can choose individual preventive measures.
So, if close relatives had/have breast and/or ovarian cancer, prostate cancer, this increases the risk of developing pancreatic cancer.
Other syndromes that predispose to the development of oncology include: Peutz-Jeghers syndrome, Lynch syndrome, familial adenomatous polyposis, multiple endocrine neoplasia syndrome, Lee-Fraumeni syndrome12.
