very dangerous manifestation of cancer is a malignant tumor of the pancreas that occurs in the ducts of the head.Its rapid growth disrupts normal functioning of the body and blocks the flow of bile, rapidly affecting the lymph nodes, nerves and blood vessels, which ultimately leads to the spread of metastasis to surrounding organs.With this overall picture of the development of cancer surgically removing it is no longer possible.
most are at risk for this type of cancer of men over the age of 60 years, with more of them men.In the early stage diagnosis of pancreatic cancer can, if he called jaundice.However, the more difficult is the case with cystic form, which is quite similar to pseudocysts or benign tumors form.In this case, you must rely on the experience of a specialist, which puts the diagnosis.
The good news is that this type of cancer is considered to be a relatively rare disease, which is diagnosed in only 2 - 3% of all cancer patients.
most common form of pancreatic cancer, which occurs in
Causes of pancreatic cancer
to ascertain the cause of pancreatic cancer, in addition to smoking, it has not yet succeeded, although there are some assumptions based on the statistics of the incidence of this type of cancer.Previously, doctors tended to the fact that excessive consumption of fatty foods and coffee can cause the formation of a malignant tumor, but these reasons are to prove it was not possible.Today just is not confirmed the theory that alcohol consumption may lead to pancreatic cancer.
Nevertheless, the presence of a genetic predisposition to chronic pancreatitis risk of this disease increases manifold.
Symptoms of pancreatic cancer
most common and eloquent symptom of pancreatic cancer is jaundice.However, its occurrence depends on the tumor.In some cases, this symptom is excluded.Among other symptoms should pay attention to unexplained weight loss, fatigue, nausea, fever, loss of appetite, dull ache at the top of the stomach, as well as reduction of the intestine.
diagnosis of pancreatic cancer
today identify pancreatic cancer at an early stage of development impossible.Until now, research is underway in this area, but so far the results are not encouraging.The matter is complicated by the fact that in the early stages of the cancer does not cause any discomfort to patients, and suspect that a virtually impossible.However, if there can be on guard encircling epigastric pain radiating to the back.At night, the pain increases, the patient loses the ability to work and feels weak.
With the development of the tumor followed by a second stage in which jaundice may occur.Detect a tumor at palpation is possible only if its size is large enough.Just when a significant amount of it happening compression of the bile duct, causing nausea, vomiting, aversion to fatty foods and meat, diarrhea, sudden weight loss.
most difficult to diagnose is a cancer of the body or tail of the pancreas, which can be determined only at a late stage of development.With this type of cancer jaundice occurs only in 10% of patients.However, such a cancer characterized by another symptom - severe pain caused by a lesion of the nerve plexus.
Treatment of pancreatic cancer
In cases where the cancer is diagnosed before metastasis, surgery is shown.This method of treatment is by far the only way to get rid of the cancer.If metastases have already spread to surrounding tissues or organs this kind of treatment is not possible.
According to statistics, only 25% of patients can carry out the operation.Number of surrounding tissue, as shown in the removal depends on the extent of the disease.In all other cases, symptomatic treatment is appointed.Unfortunately, radiation and chemotherapy in the treatment of pancreatic cancer do not give promising results.
process of metastasis of pancreatic cancer started quite early, hitting mostly the lungs, adrenal glands, peritoneum and bones.For this there are three pathways, it is lymphatic, and hematogenous implantation.
lymphogenous In the case of metastatic cancer cells initially hit the neighboring lymph nodes, gradually spreading further in the body.If the cancer cells penetrated blood vessels, then there is hematogenous dissemination means.In this case, first of all, suffer from musculoskeletal system, as well as the liver, kidneys and lungs.If the spread of cancer by implantation occurs, the peritoneum is affected, causing concomitant diseases such as cancer ascites and peritoneal carcinomatosis.
in the early diagnosis of pancreatic cancer and the operation time forecast is quite encouraging for patients.However, if the removal of the cancer is not possible, the patients die within two years after diagnosis.
Hope gives the fact that medicine today is very actively engaged in research in this area, with particular emphasis on gene therapy.At the moment, we can already speak about the success of certain of these studies that soon a comprehensive approach to treatment will help to successfully fight with pancreatic cancer.
talking about prevention in the first place it must be said about the necessity of quitting, which is the cause of many diseases.It is also necessary to avoid exposure to asbestos dust and other harmful substances.
In addition, it is important to have regular scheduled scan at the doctor, and do not ignore any manifestations of anxiety symptoms.
