Introduction: Teleportation is the process of moving objects from one place to another instantaneously. In medicine it has been little studied. The theory of relativity shows that when an object moves with velocity "v" in relation to an observer, its length X is contracted in the same direction of movement, while its time is dilated. According to this theory the dimensions Y and Z perpendicular to that direction of movement are not altered. Methods: a theoretical model has been employed, in which a human organ is inside a moving train. A near observer will determine the relative lengths and times of that organ, as it approaches or moves away. Results: the lengths Y and Z of a human organ, perpendicular to the axis of its motion, are dilated by a factor K=1/√(〖〖1-v〗^2/c〗^2 ) as it approaches the observer and they are contracted by a factor K= √(〖〖1-v〗^2/c〗^2 ) when it moves away. On the other hand, the times ty y tz of that organ, perpendicular of the axis of motion are contracted by the factor K= √(〖〖1-v〗^2/c〗^2 ) as it approaches the observer and they are dilated by a factor K=1/√(〖〖1-v〗^2/c〗^2 ) when it moves away. Conclusion: to teleport human organs, they must travel perpendicular to the line of displacement until a certain point of approximation, so that the times are contracted, while the lengths are dilated. This could be used to modify biological processes, such as cancer, acting on its time and development size.
