Cardiologist and 2022 vice presidential candidate Dr. Willie Ong announced his candidacy for the Senate in the May 2025 elections during a Facebook Live session on Monday.
Despite his ongoing battle with sarcoma cancer, which he revealed earlier this month, Ong confirmed he will file his certificate of candidacy on October 2.
His wife, Dr. Liza Ong, is en route to assist with the filing.
Ong described the tumor, measuring 16 centimeters and located behind his heart, as “deeply hidden” and blocking his esophagus, making it difficult to swallow.
He has undergone extensive testing and treatment abroad, citing frustrations with the slow healthcare system in the Philippines.
In a heartfelt message, Ong emphasized the importance of faith and community support, stating that he aims to advocate for healthcare improvements if granted a miraculous recovery.
