After Chemotherapy - What Next?

We might questioning what will be the next step when we have done Chemotherapy.
How do we know whether the Chemotherapy react positively or stuck.

Therefore we asked our doctor and he said that we can do the scan.
CT - Scan or PET CT Scan?
Which one shall be our choice?

After hearing doctor explanation, reading some from internet, considering the expense, we decided to go with PET CT Scan.

Now, the result of PET CT Scan:
There no abnormal tracer accumulation seen in the mediastinum, lung and abdomen.
No evidence of FDG avid lesion seen in the liver, adrenals and no osseous lesions noted.

But there was a solitary focus intense FDG tracer accumulation is seen in the left lower pelvis - active solitary metastatic lymph node in the left internal iliac group. Measure: 9mm*1.5cm with SUV 9.5.

What to do next after Scan?
We consult with doctor (1st), and he recommend us to have Radiotherapy as soon as possible 25 external and 2 internal. The reason, Radiotherapy was used to control the cancer cell.
With 2nd doctor on the seminar, he also suggest us to have Radiotherapy and consult with Radiotherapist.
Then we also consult with our Chemotherapy doctor. He gave us three choices:
a. Go with Radiotherapy
b. Do the Surgery, remove that part of lymph node, do the biopsy
If the biopsy prove that cancerous cell, then do the Radiotherapy. If not, then we don't need to do anything.
c. Wait for 3 to 6 months and do scanning.
If later on the measurement became bigger, then we shall do the Radiotherapy.

Why the doctor gave us choice?
Cause according to him it's just one in the left iliac, it's might be Inflamation, but it's might be cancerous cell. We could not get conclusion that the cancerous cell cause it's not proven yet, therefore he gave us a choice.
He explain to us the process of PET CT Scan, using FDG, and all.

We did search a journal in Internet about PET Scan interpretation.

We then consult with Radiotherapist (recommended by the doctor).
Before we met the Radiotherapist, I met the young assistant doctor. While discussing with him, he told one thing that seem reasonable for me.
It's near to the origin where the cancer cell start, the suv is bright, it's increase the possibility that was cancerous cell.

Then when we meet the Radiotherapist doctor, hmmmm he seem quiet for a while and then he asked me why we didn't do any radiotherapy before.
I told him that I have consult with doctor. I ever asked whether we need radiotherapy or not. The doctor gave me an answer, "If we want to we can take it, but my mom cancer was not localized anymore, it's was a systemic cancer." We think of the doctor explanation, then our choice was chemotherapy.
Then the doctor continue that we could have a choice to wait for few months also.
If we want to do the radiotherapy, need 25 times external only.

After a long discussion we came up with conclusion that we will do the radiotherapy.
We try our best to fight with this disease. Not only though medical treatment, but changing our living style, eating and thinking.
But the most importantly is not how long will you live, but how you used your life. So within this time, hope we could used the time wisely.

Next week my mother will start her first radiotherapy.
