Xeno-Grafting

A speculative medical or biological procedure involving the transplantation of tissues, organs, or genetic material from an alien lifeform into a human (or vice-versa). It's the ultimate transplant surgery, facing monumental challenges of bio-incompatibility, novel immune responses, and fundamentally different cellular chemistries. The goal could be to confer alien adaptations (radiation resistance, toxin processing) to humans, or to repair human injuries with robust alien tissues. It sits at the terrifying and fascinating intersection of xenobiology and surgery.

Xeno-Grafting Example: In a sci-fi setting, a human settler on a high-radiation world receiving a graft of photosensitive, self-repairing skin from a native "stone-hide" creature to protect against solar flares would be Xeno-Grafting. The procedure would require suppressing the human immune system while also preventing the alien tissue from metabolizing the host's body for its own, incompatible needs.

Xeno-Medicine

The field of medical science dedicated to diagnosing, treating, and preventing diseases and injuries in alien lifeforms, or in humans suffering from pathologies caused by alien environments or organisms. This is doctoring for a patient whose baseline biology is unknown. It requires developing entirely new diagnostic tools (how do you take the blood pressure of a creature with three circulatory fluids?), pharmacology (what is poison, what is medicine?), and surgical techniques for unfamiliar anatomies. It also covers human "exo-pathologies" like alien allergen responses or silicon-fiber lung disease.

Xeno-Medicine Example: A Xeno-Medic on a first-contact team tasked with healing a wounded alien ambassador would have to use non-invasive scanners to map its anatomy, analyze its biochemistry to find a safe sedative, and perhaps use a bio-printer to synthesize compatible tissue for repairs, all while avoiding a fatal cultural or biological faux pas.
