Hi, Thanks for writing in. It looks like the doctors have found a lymphnode in your abdomen and that is visible in your scan. If there is a single lymph node which is relatively small in size then it will respond better to treatment. A larger lymph node swelling can get difficult. Cancer is a challenging diagnosis and the treatment is guided by the course of the disease. No two patients will have similar disease progress and treatment is individualized. I have seen patients presenting with abdominal lymphnodes in the course of treatment for cancers in the head and neck region. It will help to take radiation as decided by your doctor. Depending on the size, location and appearance, adjuvant chemotherapy might be given depending on initial response to radiation. If possible it is better ti get PET scan done first so that it is confirmed that your nodule is an area of active disease process and to treat it early.
