CNS metastasis is the spread and proliferation of cancer cells from their original tumour to form secondary tumours in portions of the central nervous system.[1]
The process of tumour cells invading distant tissue is complex and obscure, but modern technology has permitted an enhanced detection of metastasis. Currently, the diagnosis of central nervous system, or CNS, metastasis involves high-scale imaging to produce high-definition images of internal organs for analysis. This aids doctors and clinicians in prescribing suitable therapeutic methods, though there is yet to be a perfect treatment or preventative measure.
