MANILA, Philippines -- Former president Corazon Aquino on Tuesday said she is ?on the road to recovery.?

Speaking at a mass for her recovery at the St. John Bosco Parish in Makati City, a noticeably thin but smiling Aquino said her body had responded positively to the chemotherapy treatment for her colon cancer.

Her announcement was greeted ovation by hundreds of mass-goers who filled the church to capacity.

?Blood tests showed positive results and my body responded to the treatment,? she said.

This was the second time the 75-year-old former president appeared in public since she was diagnosed with colon cancer in March.

?Suffering is a part of our lives to be with Jesus Christ,? she said.

Aquino made no political remarks but urged the public to ?pray for the leaders of our country.?

Present at the mass was Rodolfo ?Jun? Lozada Jr., the key witness in the Senate investigation into the national broadband network (NBN) deal scandal, who said he was ?happy? to hear Aquino was responding positively on her medications.

?I?m so glad; it?s one of the best news I?ve heard. She?s been so selfless,? Lozada said.

Lozada said the ?search for truth? triggered by revelations of alleged bribery and overpricing that accompanied the now-scrapped NBN deal would resume once classes open in June.

?The protest season will start once school starts,? he said.

He said he had done his part in waging the campaign for truth and accountability.

?I?ve done my part and I have no regrets. When I came out that night to the media, I was just thinking of me, and all this was unintended,? Lozada said.
