Causes of Stomach Cancer

There are several different causes of stomach cancer. Humans have control over the prevention of some of the causes of stomach cancer, while others are uncontrollable and unpredictable. An individual's diet is the backbone to his or her health. If an individual wants to remain healthy he/she must have a regimented diet full of all of the recommended items in the food pyramid. For instance, a cause of stomach cancer is a high salty, high fats diet. Eliminate these items and replace them with the recommended amount of fruits and vegetables.

Crops such as, tomatoes, potatoes, and corn can become infected with a fungus known as aflatoxin. This toxin will infiltrate into an individual's system causes several different infections. These infections can render an individual's nervous system weak, and susceptible to diseases, such as, stomach cancer. If an individual has a family history of stomach cancer, their risk factor of developing the disease at some point in their lifetime is double that of those who do not have a family history of stomach cancer. An individual's immune system combats all infections, viruses, and diseases. If an individual is currently suffering from an existing infection, it will render the immune system vulnerable to any infections, viruses, and diseases. Once an individual is infected with an infection such as Helicobacter Pylori, it leaves their body defenseless against other diseases they come in contact with. An individual's immune system combats all infections, viruses, and diseases. If an individual is currently suffering from an existing infection, it will render the immune system vulnerable to any infections, viruses, and diseases. Once an individual is infected with an infection such as long term stomach inflammation, it leaves their body defenseless against other diseases they come in contact with. An individual's immune system combats all infections, viruses, and diseases. If an individual is currently suffering from an existing infection, it will render the immune system vulnerable to any infections, viruses, and diseases. Once an individual is infected with an infection such as Pernicious Anemia, it leaves their body defenseless against other diseases they come in contact with. This dangerous habit slowly destroys an individual internally. This internal breakdown leaves an individual susceptible to infection, viruses, and diseases. An individual is mainly susceptible to cancer, because the effect the 4,000 chemicals each cigarette holds. An individual's immune system combats all infections, viruses, and diseases. If an individual is currently suffering from an existing infection, it will render the immune system vulnerable to any infections, viruses, and diseases. Once an individual is infected with an infection such as stomach polyps, it leaves their body defenseless against other diseases they come in contact with.
Types of Stomach Cancer: Stomach cancer is a type of cancer that develops within the lining tissues of the human stomach, also referred to as gastric cancer. In total, there are five different stomach cancer types: adenocarcinoma, gastric lymphomas, GIST, Carcinoid cancer, and Leiomyosarcoma. Research is still being conducted in order to better understand each of the different stomach cancer types. Adenocarcinoma is the most frequently diagnosed, making up for approximately ninety to ninety-five percent of all stomach cancer cases in the United States. Nonetheless, each of the five stomach cancer types can be equally dangerous and harmful if the proper treatment methods are not followed. Many cases of adenocarcinoma, and other stomach cancer types, can be treated with surgical procedures, but an early detection of the disease is crucial in order to prevent the cancer from spreading to other parts of the body.
Adenocarcinoma: Adenocarcinoma is stomach cancer that originates from the gland cells found in the innermost linings of the stomach. It is almost certain that a newly discovered malignant cancerous tumor in this area will be labeled adenocarcinoma. Though adenocarcinoma is the most common of all the stomach cancer types, it can be just as deadly as some of the rarer forms. There are five stages in which the cancer can be classified, with the last, Stage IV, being the most fatal.   

Gastric lymphomas: This is defined as stomach cancer that develops within the immune system tissues along the walls of the stomach. Next to adenocarcinoma, lymphoma is the second most diagnosed of the stomach cancer types. The tumors caused by lymphoma are often hard, causing extreme discomfort. Preventative and treatment methods are usually determined after a full diagnosis of lymphoma; there are some cases where the lymphoma cancer cells are overly active and aggressive while other cases present a more slowly developing lymphoma.   
Gastrointestinal Stromal Tumors (GIST)
: This form of cancer, unlike adenocarcinoma, develops along the tissues that maintain the digestive organs. These tumors develop at a much slower pace than adenocarcinoma or lymphoma and originate from the stomach muscles. Some of the symptoms for gastrointestinal stromal tumors include pain or discomfort in the abdominal area and trouble swallowing foods. Cancer caused by Gastrointestinal Stromal Tumors is one of the more rare stomach cancer types.  

Carcinoid Cancer: Carcinoid cancer, also known as carcinoid tumors, originates from the tissues within the digestive system that are responsible for producing hormones. Carcinoid cancer releases hormones and/or chemicals into different blood streams causing symptoms for this cancer to emerge throughout different parts of the human body. However, while the symptoms of carcinoid cancer may be evident in various body parts, the actual tumors do not spread into the other body parts, making removal of the tumors a relatively easy task.  

Leiomyosarcoma: Leiomyosarcoma is perhaps one of the most rare stomach cancer types. This disease develops in the smooth muscle cells contained within the stomach walls. This cancer eventually grows to a point where it is unstoppable and develops tumors. Leiomyosarcoma is actually a form of cancer that can affect other body parts, not just the stomach. Cases of this disease have been found in the uterus, intestines, and even the skin. The most common site for Leiomyosarcoma to be diagnosed, however, is in the stomach.

Stomach Cancer Stages: As with any other form of cancer, there are various stages through which the cancer will progress over its course. For each unique type of cancer, there is a varying amount of stages. The different stages are categorization methods to differentiate the severity and duration of the cancer in a particular patient. In all, there are five different stages of stomach cancer. The earlier stomach cancer stages are the least dangerous and treatment methods are much more efficient and effective for an early detection of stomach cancer. As the stages of stomach cancer progress, the severity and harmfulness of the cancer also increases. Most cases of stomach cancer are treated with surgery, but as mentioned above, it is always in the better interest of the patient to be treated as soon as possible.

Stage 0, the first of the five stages of stomach cancer, is also the least harmful. A cancer found at Stage 0 is considered to be in the very beginnings of the disease, and non-invasive surgery may be an option to treat the stomach cancer. The cancer is usually found in the innermost layer of the stomach wall in the first of the stomach cancer stages.   

Stage I, Stomach cancer is considered to be in Stage I if the cancer has spread out beyond the first layer of the stomach. It is possible for lymph nodes to be growing in Stage I of the stomach cancer stages however the lymph nodes will most likely be in the near vicinity of the tumor.  
Stage II, of the different stages of stomach cancer can be defined by three possible criteria. It is likely that lymph nodes will have started to form near the tumor while the cancer is developing in the third layer (muscle layer) of the stomach. It is also possible for the cancer to be found in the second layer of the stomach wall with lymph nodes spreading farther from the tumor. The last possible condition for Stage II of the stomach cancer stages is the cancer being found in all four layers of the stomach with no sign of lymph nodes.     
Stage III
, In Stage III of the various stages of stomach cancer, it is likely that lymph nodes will be evident around the tumor and in some cases; the lymph nodes may have started spreading to other parts of the body. In Stage III, it is also very likely that the cancer has developed in all four layers of the stomach wall, and possibly into the surrounding tissues near the stomach.    
The last of the stomach cancer stages, Stage IV, is the most dangerous and harmful of all the stages of stomach cancer. Stage IV stomach cancer will have affected the entire stomach area with lymph nodes, along with a very likely possibility of the spread of the cancer into surrounding tissues and organ.

Stomach Cancer Treatment: Surgery:- Surgery is a widely recommended treatment method for various types of cancers. Certain kinds of cancers may be treated with prescribed medicines, but a large number of cancer patients usually require some form of surgery to alleviate the symptoms and the spread of the cancer. Stomach cancer surgery is a common procedure, and one that has been found to be one of the most effective methods to treat stomach cancer. Depending on the severity and the stage of the disease, a stomach cancer surgery can usually remove the cancer and the affected areas of the stomach. As with any other form of cancer, an early detection is essential to ensure that the cancer does not spread into other parts of the body. Most patients who are still in the earlier stages of the cancer are eligible for an operation, but only some of stage IV cancer patients will be able to take advantage of a stomach cancer surgery. As the stages of cancer progress, it is more likely that the disease will affect other parts of the body.    Depending on the stage of the cancer, there are different types of stomach cancer surgery available for patients. An endoscopic mucosal resection is a type of stomach cancer surgery which is the least invasive of all the options, and is usually most effective on patients in the very beginning stages of stomach cancer. For those patients in the later stages of the cancer, a stomach cancer surgery called a gastrectomy may be required. A subtotal gastrectomy is a partial removal of the affected areas of the stomach while a total gastrectomy is a more complete removal of the stomach along with the cancer and lymph nodes. A total gastrectomy is a complicated procedure which involves the surrounding organs, and will affect the patientís eating habits after the procedure is done. Stomach cancer surgery, as with any other type of surgery, is a very delicate procedure which should be done by a surgeon or doctor that you trust. In the case that a stomach cancer surgery is necessary, ensure that the surgeon treating you and hospital you are being treated at is experienced and skilled in such operations.

Radiation Therapy Stomach Cancer: Radiation therapy is a commonly used procedure for stomach cancer treatment to destroy cancer cells.  Radiation therapy is often used as an follow-up therapy after surgery to destroy small deposits of cancer cells that may still remain.  Some patients prefer a treatment of radiation therapy and chemotherapy to shrink the cancer and avoid invasive surgeries. There is one type of radiation therapy commonly used for stomach cancer treatment. In external beam radiation therapy, the doctor will conduct a review of the patient's medical history and test results.  Afterward, he or she will determine the area to receive the radiation therapy.  When the doctor determines the amount of radiation and how it will be given, treatment begins.  In most cases, radiation is not capable of destroying a tumor within one session.  Therefore, external radiation is usually given in fractions, most often on a daily basis, 5 days a week for 5 to 8 weeks.  The amount of stomach cancer treatment a patient undergoes is dependent on the size, location, and type of the cancer as well as the specifications of the patient. This stomach cancer treatment focuses radiation on cancer from a machine that is outside of the body. The treatment is very similar to an ordinary x-ray, except it is given during a much longer period of time. A patient will receive the radiation therapy about five times a week for a period of weeks or months. When combined with other treatments, such as chemotherapy and surgery, the stomach cancer treatment can be quite effective,

While external beam radiation therapy is relatively safe, there are certain side effects that may arise during the course of the treatment. The side effects are usually mild and temporary. They include: 

| Skin problems at the site of the radiation therapy; | Diarrhea; | Nausea and vomiting; | Fatigue; | Low blood cell counts |

These side effects usually take several weeks to go away once radiation therapy is finalized. Long-term effects of radiation therapy, while difficult to predict may prove to be more harmful. Radiation therapy can also help reduce symptoms of advanced stomach cancer, including pain, bleeding, and problems associated with eating.
