If I am being treated for liver cancer can I be treated while on medication?

The full treatment would be if the time had stopped with in five minutes of the full time. It sounds like you had an error which stopped the machine. If you had loss suction, it could have been re treated in that area. I would contact your provider to discuss retreating. 

I would massage the area every day for a few minutes. Wait until at least 3 months following treatments to do anything. The treating practice should open a clinical case with Allergan for that outcome if it doesn't improve. That way, if you have to get treatment to fix it they might help you. ...

Absolutely. In my practice I encourage my patients to do few sessions with Venus Legacy afterwards since it appears that the deep heat and the combined massage of the Venus helps to break down the fat cells faster.
