Colon cancer has for a period of time, after it has been developed by a patient, no symptoms. This happens for about six to twelve month, period in which the cancer can evolve form the first stage, to the last one. Although there is not a colon cancer single cause that can determine the disease, there are many risk factors that can contribute to the disease development. The early diagnosis of colon cancer is very important and that is way you have to be very careful about the risk factors and the colon cancer causes.

So, symptoms may not be clear at the beginnings of the disease. They may include constipation, diarrhea, the alternation between the two of them, some associated pain, weakness or the loose of blood in the stools. However, one of the first signs of colon cancer is the excessive gas.

Gas and bloating can result from many things like swallowing too much air or eating too much sugar, starches or fiber, which is way when this occurs, people do not think that something may not be in order. Besides colon cancer, excessive gas and bloating can be a sign of intestinal disorders like irritable bowel syndrome.

Excessive gas is a sign of colon cancer, maybe one of the first symptoms that may occur on a patient. In some cases the tumor created by the cancer causes the bowel blocking. This is how gas can be obstructed form passing by. The excessive gas and bloating can also be a sign that the colon cancer has grown. Even if the tumors created by the cancer are not large enough to cause a blockage of the bowel, stools can be held because of the tumor. That is way in many cases the excessive gas is associated with constipation.

Bloating occurs when the air is trapped by the bowel blocking. In this case stomach cramping and a clear decrease of the number of times you pass gas will happen. Many people are diagnosed with colon cancer after they had a bowel obstruction manifested by excessive gas and bloating. So, if you have chronic gas and bloating you should have a medical check as soon as possible.

Colon cancer symptoms tend to be hidden in the first stage of the disease. Some of the symptoms can be associated with other diseases, such as bowel infections or hemorrhoids. In fact most colon cancer patients think they have hemorrhoids when they actually have developed a cancerous tumor. The same thing happens with chronic gas. Excessive gas is a sign of colon cancer in many cases and that is way it should not be ignored and treated at home without a diagnoses made by a doctor.
