The actresses in “Total Recall” were not truly bare chested. They wore a whole chest prosthesis. As to how well endowed those ladies were before application of the chest piece, I could not say.
But being serious for a moment, modern silicon body part prosthetics are amazing and a very important part of helping people who have been in some way disfigured. A prosthetic can provide them with the confidence to socialise without concern. Wonderful technology, likely born out of the amazing special effects teams who work on film productions

Thermal imaging can reveal anomalies when viewing a person. There has been research into the medical use of thermal cameras since the 1970’s. It was used to image blood circulation in limbs and also differential breast analysis in connection with tumour detection. Thermal imaging is still an important tool in the detection of travellers who may be running a temperature due to a contagious disease. Veterinary science also includes thermography of such animals as horses in an effort to identify areas of inflammation or injury in their very fragile legs. It is not a magic wand type tool but it can aid in the diagnosis or early spotting of ailments that cause thermal change in the patients body.
I have several modern and well respected medical thermography books that a nurse gave to me. She was specialising in the medical applications of thermal cameras. Very interesting reading. Many Delta T generating illnesses can be diagnosed without the thermal camera but the camera provides visual information in order to better understand the situation in research and practice. People with colds know they have a cold, but seeing the face of such a person through a themal camera can be very impressive !
