Normalising Medical keywords

I need to normalize medical terms within a large corpus, where variations in spelling exist for words with the same meaning (e.g., x-ray, xray, xr). Manual normalization is impractical due to the size of the dataset. I'm looking for a solution, such as a specialized lemmatization or stemming method tailored for medical terms, as conventional methods are not effective in this context. Any suggestions or solutions are appreciated.
