<s>[INST] Hi! My father got a tumor of size 4.2cm at his neck 3 months back. Then after he underwent chemotherapy and radiotherapy treatment for one month. Now tumor size is 1.2cm.My doctor has planned 12 more days of Radiotherapy treatment. Please let me know will this 12 days of radiotherapy completely removes the tumor and likely to cure the disease. [/INST] dear rajesh, is he suffering from lymphoma, you dint write about the diagnosis. If he is having lymphoma, it is likely to be stage 1 (A?/ B? ). it is a curable disease, but without details it is difficult to comment. </s>
