A laser therapy method and a laser therapy apparatus whereby heat injuries such as transpiration and coagulation necrosis can be surely exerted on a target tissue to be injured and thus the diffusion of cancer cells etc. can be prevented under unusually high pressure due to the transpiration of the affected tissue regardless of the laser beam absorption ratio which varies depending on the color tone or composition of a biological tissue. In this method, a highly laser beam-absorbing medium is injected between an affected tissue to be irradiated by laser and the laser beam and then the medium is irradiated with the laser beam. Thus, heat injuries such as transpiration and coagulation are exerted on the above target tissue. In case where unusually high pressure arises due to the transpiration of the affected tissue, this pressure is introduced outside.
