The Philippine Cancer Society, Inc. (PCSI) is a private, non-stock, non-profit corporation registered with the Securities and Exchange Commission on 22 December 1956. It was founded by a group of laymen and medical doctors with the aim of “helping the Filipino cope with cancer by preventing it and diminishing death caused by it, especially among the disadvantaged, through information, education, advocacy and focused services.”

Within this next half-decade, we aspire for a state of affairs with the following features:

1. The information, education and advocacies of the PCS are sufficiently disseminated and effective so as to persuade behaviorally the responsible agencies and a significant number of the Filipino population towards proper handling of cancer as a public and personal health problem.
2. Filipinos, especially the disadvantaged, confidently and readily seek and obtain cancer information, access to diagnosis, tratment and support through the help of the PCS and its network of partners.
3. The PCS has sufficient organization and resources, its own and through a working netowork of partners, to provide cancer information and access to diagnosis, treatment and support effectively and efficiently.
4. The PCS is recognized for its leading and effective role against cancer and is readily and continuously supported by the community in terms of volunteers and donations.

The PCSI is a private, voluntary organization governed by a Board of Trustees (BOT) duly elected during the general assembly of members. The BOT is made up of distinguished medical professionals and laymen known for their involvement in civic and charitable works. The BOT constitutes working committees as needed. The Society has a Council of Advisers made up of former BOT members and various civic leaders from different fields. The Council of Advisers, BOT and committee members are all volunteers. Day-to-day operations are overseen by a managing office headed by an Executive Director.
