Cancerstomach - a malignant tumor that develops from the epithelium of the mucous membrane of the stomach.The disease is the most common cancer diseases.
exact reason that causes the disease, has not yet been established.Experts call the main factors that trigger the appearance of the disease.
Malnutrition.The risk of developing malignant tumors in the stomach increases significantly with frequent use of fruits and vegetables with a high content of nitrites and nitrates, spicy, dried, smoked, fried foods.
Alcohol and smoking.Alcohol abuse, especially on an empty stomach, is another factor that provokes the development of gastric cancer.Smoking greatly increases the risk of this disease.
There precancerous gastric diseases that can eventually move into cancer or cancer can develop on their background.These diseases include:
Clinical symptoms of stomach cancer are quite diverse.They depend on the location of the cancer, the nature of its growth, stage of development, the presence of precancerous diseases and complications.
Symptoms of stomach cancer is conventionally divided into general and local.
Common symptoms of the disease are:
Local symptoms of stomach cancer include:
There are three clinical forms of the disease course.Each of these is characterized by certain symptoms of gastric cancer.
1.Latentnaya form.It is characterized by asymptomatic disease.When probing the abdomen patient or physician detected tumor formation.the tumor is often detected incidentally during diagnostic procedures such as X-ray examination.
2.Bezbolevaya form.Manifest local and general symptoms of stomach cancer.But in this case there is no pain.
3.Bolevaya form.Often there is pain in the upper abdomen.They can give in the waist.Often the pain intensifies during movement may continue for a long time.The peculiarity of pain in this disease is that it is not of a regular nature.There is no pain, depending on the season, meals.Sometimes the pain have a greater intensity.In the case of tumor sprouting in the pancreas, or even further, patients complain of back pain.Often, these patients are treated for neuralgia, sciatica.
Symptoms of gastric cancer depend on the location of the cancer.In cancer of the antrum (the final part of the stomach) relatively quickly severity occurs in the upper abdomen, vomiting rotten, unpleasant odor.When the cancer is in the stomach (the middle part of stomach) no local symptoms over time.The patient observed common symptoms of stomach cancer.In the case of cardia cancer (part of the stomach, which is adjacent to the esophagus), the patient has a gain salivation, difficulty swallowing roughage.Local symptoms of stomach cancer while include food regurgitation, feeling of pressure or dull pain in the sternum, in the interscapular region or in the heart.
specialists use the following classification of disease stages.
zero stage.at this stage of disease is also known as vulvar cancer.The inner surface layer of the mucous membrane of the stomach wall contains abnormal cells.They can form a malignant tumor and enter the neighboring normal tissues.
first stage of gastric cancer.Malignant tumor has formed.Depending on the mode of spread of cancer, isolated stage IA and stage IB.
Stage IA indicates that the cancer has spread to the entire area of the mucosa of the gastric wall.
Stage IB indicates the spread of cancer:
second stage.Mean that the cancer has spread:
third stage of gastric cancer.Depending on how the spread of the disease, the third stage is divided into IIIa and ІІІV.
Stage IIIa indicates that the cancer has spread to:
Stage ІІІV means the spread of cancer to the serous layer of the stomach wall and 7-15 lymph nodes nearby.
fourth stage of gastric cancer.Cancer has spread to:
treatment of gastric cancer is directed at the person's full recovery, or, failing this, to get rid of severe symptoms.
main method of treatment of this disease is surgery.Only if timely operation possible complete removal of malignant tumors and the subsequent cure.The volume of surgery depends on the location of the tumor and its size.Usually surgery is not carried out in case of a patient metastasis to other organs.
also in the treatment of gastric cancer chemotherapy is used.In the body of the patient is administered drugs that can inhibit the growth of cancer cells and destroy them.Chemotherapy can be performed as an independent method of treatment, and as an additional method of postoperative.
Radiation therapy in the treatment of gastric cancer is not high efficiency.
forecast gastric cancer is often unfavorable.It depends on the degree of germination of the tumor in the stomach wall, lymph node involvement and the presence of metastasis.A more favorable prognosis of gastric cancer at an early stage diagnosis and timely start of treatment.Significantly worsens the prognosis of gastric cancer in the presence of metastasis in organs and tissues.
