A controlled heating apparatus for damaging or killing cancerous cells in a living human body, said apparatus being configured for:
- heating a portion of said living human body surrounding cancerous cells, such that said cancerous cells are damaged or killed, while detecting and monitoring a temperature of said cancerous cells;
- wherein glucose has been introduced to said portion of said living human body thereby raising said temperature of said cancerous cells more than a temperature of non-cancerous cells;
- wherein said heating is being carried out by bombardment of radiofrequency energy or ultrasonic energy to heat said cancerous cells containing said glucose to a temperature that is above a critical temperature that damages or kills said cancerous cells while keeping said non-cancerous cells below said critical temperature to avoid damaging or killing said non-cancerous cells.
