My dad was diagnosed of stage 4 Nasopharyngeal Cancer last Aug 2012. On September of same year, he had undergone 3 cycles of chemo and radiation therapy for 20 sessions. It was successful. Close monitored for 1 and a half year of MRI every 6 months. However, on February 2015, MRI results to a tumor recurrence. He was treated again chemo that same year and we're glad it was successful (Oct 2015). Monitored again by MRI's. We tried the Petscan since it was recommended to make sure if it (the mass showing on MRI results) is an active tumor or not. Unfortunately, it's active. As of now, he's trying herbal alternatives while we seek help from friends, relatives and from this helpful fundraising website to gather funds for his chemo. I would like to express my sincere appreciation to those who can help. God bless us all.
