Hitaishini is a non-profit charitable organization formed with the sole purpose of helping breast cancer patients in eastern India. It is run entirely by women cancer warriors and some community committed women in West Bengal. The activities are actively supported by women social workers and health professionals and are solely dependent on voluntary donations and fundraising activities. Besides running free breast cancer clinics at different cancer hospitals in and around Kolkata to help and guide poor and needy female patients coming from other parts of the eastern region, Hitaishini organizes regular programmes to enhance cancer awareness among the people.
