Ikebukuro Clinic is a "never-give-up cancer specialist clinic" located in Minami-Ikebukuro, Toshima Ward, Tokyo, offering comprehensive treatment that combines NK therapy and other immune cell therapies. The clinic accepts patients regardless of cancer type, location, or progression, and provides treatment options for advanced and terminal cancer patients, as well as for recurrent and metastatic lesions. NK cells circulate throughout the body with the blood, eliminating cancer cells remaining anywhere in the body, and are expected to have recurrence prevention effects. The clinic also offers combination therapy with non-immunotherapy methods and is used in combination with standard treatments (three major treatments). Furthermore, the clinic provides regenerative medicine using autologous adipose-derived stem cells, aiming for symptom improvement by leveraging tissue repair functions and anti-inflammatory effects. The clinic has submitted numerous regenerative medicine plans to the Ministry of Health, Labour and Welfare and has been approved, featuring treatments aimed at enhancing immunity and supporting QOL (quality of life) improvement. The clinic accepts credit cards, debit cards, and electronic payments, and is fully barrier-free accessible.
