Cancer can target any age group, but nearly all types are more common in middle aged and elderly people than in young people. Skin is the most common type of cancer for both men and women. The next most common type among men is prostate cancer; among women, it is breast cancer. Lung cancer, however, is the leading cause of death from cancer for both men and women . Brain cancer and leukemia are the most common cancers in children and young adults.
The more we can learn about what causes cancer, the more likely we are to find ways to prevent it. Scientists study patterns of cancer in the population to look for factors that affect the risk of developing this disease. In the laboratory, they explore possible causes of cancer and try to determine what actually happens when normal cells become cancerous.
basics of stomach cancer
Out of ten people, there will be one person suffering from gastritis and out of one hundred, there will be one person suffering from stomach cancer. If the cancer can be identified early (when it only involves the superficial lining layer of the stomach and only involves a few cells) it is surgically removed. 90% of these individuals are likely to have a normal life span. However if the stomach cancer has involved all the layers of the stomach this chance decreases to only 50% and if it has spread outside the stomach or to distant organs of the body the chances of surviving in the long term are extremely gloomy.
causes of stomach cancer
- Benign stomach (gastric) ulcers, in most instances these benign ulcers in the stomach do not become malignant although in a few cases, they can become cancerous after many years . Helicobacter pylori infection of the stomach appears to be an important cause of gastric ulcers.
- Chronic duodenal ulcer , this is a common condition of the duodenum , the organ situated next to the stomach . We can reassure those with this condition that even after many years of having a chronic duodenal ulcer , the chances of it becoming malignant are almost zero.
- Gastritis with low or absent stomach acid production . This situation can occur in an uncommon illness. Pernicious anemia and it can also occur without any obvious reason . No or low levels of stomach acid which is normally produced to aid digestion is associated with the disappearance of gastric glands and this is called atrophic gastritis . Atrophic gastritis is a pre malignant condition .
genetic disposition to stomach cancer
Family history plays a large role in determining your chances of getting stomach cancer. For example, such a history in a near relative doubles a person’s chances of developing stomach cancer during their life time
The common blood groups are A,B,O ,and AB. A person with type A blood has a 20% increased chance of developing stomach cancer during their life time compared to those with other blood groups
The presence of Helicobacter pylori in the stomach also increases your chances of developing stomach cancer. This is an organism which in recent has been associated not only with stomach cancer but also with gastric and duodenal ulcers and with inflammatory changes called gastritis. Why Helicobacter infection is present in some individuals but not in others is at present in some individuals but not in others is at present is uncertain. Helicobacter Pylori infection can usually be eradicated by the use of suitable antibiotics . It has also been suggested recently by Australian scientists that the regular intake of acidophilus bacteria (found in some brands of yogurt and in some bacteria supplements) can also eradicate Helicobacter infection.
Dietary factors play a special risk for stomach cancer, the most common or which is a diet which is low in vegetables, fruit and cereals. Most notably are those fruits, vegetables and cereals which contain a lot of beta-carotene, vitamin c, and vitamin-e.
A diet high in pickled, smoked, salted, or cured food or foods preserved with nitrates such as salami, sausages, hot dogs, smoked meat, smoked fish, or pickled food of any kind can also increase your risks for stomach cancer. The high risk foods described above all seem to produce carcinogens called nitrosamines. Vitamin C acts as antioxidant and has other actions which neutralize the effects of nitrosamines . Dietary factors are probably the most important single cause of stomach cancer. Smoking is also very likely to be an important contributory cause of stomach cancer .
what you can do to prevent stomach cancer
Make dietary changes. It is particularly important to consume a diet containing fruits,vegetables and cereals which contain beta-carotene, vitamin c and vitamin e and at the same time avoid or eat very little pickled, smoked, salted, cured and nitrate preserved foods. In a recently reported study from China, where stomach cancer is still relatively common, the daily use of vitamin-e, beta carotene and selenium supplements decreased stomach cancer risk by one-fifth .
Avoid smoking. If you are a smoker, there are several plans available to help you quit smoking. Many times at no cost to you.
Eradicate Helicobacter Pylori , if helicobacter infection has been shown to be present ,suitable antibiotics can be used recent research suggests that the acidophilus bacteria found in some dietary supplements may also been effective way to eliminate helicobacter infection
The regular use of aspirin as a preventive for stomach cancer is also being explored . However the human evidence of a preventive role for aspirin in stomach cancer is insufficient at present to make a strong recommendation .
treatment for stomach cancer
Many people with stomach cancer want to learn all they can about their disease and their treatment choices so they can take an active part in decisions about their medical care. Often, it helps to make a list of questions to ask the doctor. Patients may take notes or, with the doctor’s consent, tape record the discussion. Some patients also find it helps to have a family member or friend with them when they talk with the doctor to take part in the discussion, to take notes, or just to listen.
Chemotherapy is often used to treat stomach cancer. The side effects of chemotherapy depends mainly on the drugs and doses the patient receives. As a result of chemotherapy, patients may have side effects such as loss of appetite, nausea and vomiting, hair loss, or mouth sores. For some patients, the doctor may prescribe medicine to help with side effects, especially with nausea and vomiting. Usually, these side effects gradually go away during the recovery period or after treatment stops. Hair loss another side effect of chemotherapy, is a major concern for many patients. Some chemotherapy drugs only cause the hair to thin out, while others may result in the loss of all body hair. Patients may feel better if they decide how to handle hair loss before starting treatment.
In some men and women, chemotherapy drugs cause changes that may result in a loss of fertility. Loss of fertility may be temporary or permanent depending on the drugs used and the patient’s age. For men, sperm banking before treatment may be a choice. Women’s menstrual periods may stop, and they may have hot flashes and vaginal dryness. Periods are more likely to return in young women. In some cases, bone marrow transplantation and peripheral stem cell support are used to replace tissue that forms blood cells when that tissue has been destroyed by the effects of chemotherapy or radiation therapy.
Hormone therapy is another option for many suffering from stomach cancer. Patients may have nausea and vomiting, swelling or weight gain, and, in some cases, hot flashes. In women, hormone therapy also may cause interrupted menstrual periods, vaginal dryness, and, sometimes, loss of fertility. Hormone therapy in men may cause impotence, loss of sexual desire, or loss of fertility. These changes may be temporary, long lasting, or permanent.
