A system to be used in a tumor treatment, comprises a trocar, a device and connection cables. A trocar that is used to puncture a patient's body at entry site to a tumor location, comprises a first portion with a cutting edge and a heat generating element, an elongated body and a second portion. A device that is connected to a trocar to provide a heat generating element of a trocar with a necessary energy. A device has a radiofrequency current generator to supply and control the energy supplied to a heat generating element.In operation, there are two steps, in a first step, a trocar is inserted into a tumor location, then a salty solution is pump within a tumor area via a syringe and oblique ports of a heat generating element to cause tumor's cells to shrink. Then after a shrink effect a salty solution is sucked via a syringe. In a second step of operation, a higher temperature may be achieved in cancer cells via the activation of a heat generating element to produce a precise and adequate temperature intracellularly to kill cancer cells.
