How to Know the Symptoms of Stomach Cancer

It is important to know the symptoms of stomach cancer to obtain the necessary treatment. Stomach cancer, also known as gastric cancer, is not as common in the United States as it is in other parts of the world. Symptoms of stomach cancer often tend to be ignored because people think they are suffering from other stomach problems. There are different reasons that cause stomach cancer. The most common type of stomach cancer is known as adenocarcinoma. Stomach cancer can be genetic. If you have relatives who have had stomach cancer then you could be at risk because the signs of stomach cancer are usually not noticeable until the disease is advanced. You should get regular check ups from your doctor, especially if you are over 40 years old. Those over 40 are more prone to stomach cancer. Those who are at risk of stomach cancer are heavy smokers, drinkers, people with excess sodium in their diet and /or a lack of antioxidants in their diet, and pernicious anemia. The treatment for stomach cancer involves surgery.

In order to avoid stomach cancer there are several habits that can help prevent this disease.

Eat foods that are high in fiber. Fiber expels toxins from your body. Dietary fiber is good for your digestive system. Eating a good amount of fiber can help prevent stomach cancer. Foods high in fiber include wheat, corn, raspberries, mustard greens, cauliflower, broccoli, bran, legumes, barley, rye and oats.

In the case of wheat and foods made with flour, it's important to replace them for others that are made with wholewheat flour as it's got much more fiber and is healthier for our organism.

I am having constant diarrhea. My stools are not dark or bloody. I am 73, smoke, and have diabetes. From ti.e to time, it clears up but I have seen what appears to be a mucus on my small movements. The diarrhea is uncontrollable.
