[6] This is a sign that the cat is suffering from anxiety. [8] [9]

The mechanism of this malignant cancer is still unclear; however, it has been found that a colon carcinoma cell known as HCC2998 causes an increase in differentiated tumor production. The reason for this increase is due to active PI3K that are converted to a SRCC-like cells.
The diameter can range from a few millimeters to more than 30 cm. Larger tumors usually cause symptoms in contrast to those found incidentally which tend to be smaller and have better prognosis. [4] [20] Large tumors tend to exhibit malignant behavior but small GISTs may also demonstrate clinically aggressive behavior. [21]
