But, on certain occasions, a stomach ache can be indicative of a far more serious problem - digestive track complications, colitis and even cancer.

In cases involving colonic cancer and colitis, timely intervention can save the lives of 70-80 per cent of patients. So, make it a point to visit your doctor regularly for check-ups.
Gastrointestinal cancer usually begins in the mucus-producing cells that line the stomach. This type of cancer is called adenocarcinoma.For the past several decades, rates of cancer in the main part of the stomach (stomach body) have been falling worldwide. During the same period, cancer in the area where the top part of the stomach (cardia) meets the lower end of the swallowing tube (esophagus) has become much more common. This area of the stomach is called the gastroesophageal junction.
Stage I: Cancer has grown into the inner layer of the wall of the stomach
Stage II: Cancer has grown into the outer muscular layers of the wall of the stomach
Stage III : Cancer has grown through all of the layers of the muscle into the connective tissue outside the stomach and has grown into nearby organs or structures
Stage IV: Cancer has spread to the liver and to the inside of the abdomen. Less commonly, it can also spread to the lungs.
