“I can recommend the Cancer Center of Irvine very highly. My wife and I have been very impressed with my entire treatment. Drs. Tokita and Yeh are outstanding and are always available for a consultation and to answer your questions. The staff is very professional, efficient, well teamed, and knowledgeable. They care about the patient and the patients comfort. I could always get answers to any of my question. I dreaded the long drive from my home to Irvine, every day for my treatment but, very soon, I felt it was definitely worth it to have such excellent treatment here.” – Jay
