Hi, Thanks for writing in. It is important at what stage the cancer is progressing in your relative. Moderately differentiated cancer is the grading and tells that the cell multiplication is neither too aggressive nor to slow. It is progressing and can be treated as it has been confirmed. First it is important to know if the cancer can be operated and this is important. AN early surgery limits the disease but chemotherapy and radiation have to be given for better cure of the patient. While surgery is important to remove the tumor, chemotherapy and radiation will stop the disease from getting out of control. Regular ultrasound and CT scan should be done for a few years to follow up and check for any spread of disease to liver and lungs. Any spread has to be confirmed early and treated on time. Please do not worry.
