American Oncology Institute (AOI), the international brand for US-based Cancer Treatment Services International (CTSI), is the only cancer center in India (cancer hospital in india) managed by American medical experts. AOI provides evidence-based, comprehensive cancer care matching top American standards for quality and safety and seals the gap between standards of care in India and the US.

In addition to providing the same level of care as top US hospitals, AOI locations feature state-of-the-art technology not widely available in India such as the TrueBeam linear accelerator, the Calypso System, fully-integrated Electronic Medical Record (EMR) and 4-D PET/CT. For patients requiring surgery, AOI partners with eminent hospitals to provide world-class, multidisciplinary cancer care.
