My elder sister has been admitted in Kolkata Medical collage with a problem of liver metastasis after having a full abdomen CT scan. He had some problem of osteoporosis of spine which has been detected after a MRI is done but in MRI it is also reported the same thing that metastasis of tumor. Doctors over there are still under searching the source of this tumor which has been scattered. Report of Endoscopy has given the same symptom. Now doctor is advising to have colonoscopy by 5th September i.e. Day after tomorrow. My question is: should we now consult with an oncologist though medical college is suspecting but not sure that it is a case of oncology.
