The Tata Memorial Hospital was initially commissioned by the Sir Dorabji Tata Trust on 28 February 1941 as a center with enduring value and a mission for concern for the Indian people.

In 1952 the Indian Cancer Research Centre was established as a pioneer research institute for basic research - later called the Cancer Research Institute (CRI). In 1957 the Ministry of Health took over the Tata Memorial Hospital.

The transfer of the administrative control of the Tata Memorial Centre (Tata Memorial Hospital & Cancer Research Institute) to the Department of Atomic Energy in 1962 was the next major milestone. The Tata Memorial Hospital and Cancer Research Institute merged as the two arms of the Tata Memorial Centre (TMC) in 1966 as a classic example of private philanthropy augmented by Government support with a mandate for Service, Education & Research in Cancer.

The Tata Memorial Hospital is situated in Parel, Mumbai in India. It is a specialist cancer treatment and research centre, closely associated with the Advanced Centre for Treatment, Research and Education in Cancer (ACTREC). One of the fields of specialization of this hospital is in the treatment of acute lymphoblastic leukemia (A.L.L). The hospital claims to treat and cure 99% of the A.L.L patients. This hospital is also one of the few in India to have a P.E.T. scanner. Every year nearly 30,000 new patients visit the clinics from all over India and neighboring countries.

Nearly 60% of these cancer patients receive primary care at the Hospital of which over 70% are treated almost free of any charges. Over 1000 patients attend the OPD daily for medical advice, comprehensive care or for follow-up treatment. During the year 2003, over 20000 new cases were registered in addition to over 13000 Referral Cards issued for only special investigations. Nearly 8500 major operations are performed annually and 5000 patients treated with Radiotherapy and Chemotherapy annually in multi-disciplinary programmes delivering established treatments.
