Sorry to hear your father's condition.

All of you just need to sit tight and wait for the processing. It is utmost important to get a complete body scan before anything else. Since it's government hospital, it may take awhile, just check the appointment with the doctors and administration on hand. Remember be nice to them too

While there is a looming thought on this, please stay positive and don't get over worried as it will worsen the condition. Positive and strong mental health goes a long way fighting this process. Just get back to routine and enjoy time with family.
