Providence Patient
Dr. Panares takes care of my stage [ID] Breast cancer. I have been a patient for almost 10 years. I believe I am alive from his wealth of knowledge of new treatments and the decision making to change treatments when they no longer work. He is super fast at a recent change in how my cancer has changed and spread over time. In [Date] 2019 will be 5 years since I was diagnosed stage [ID]. I am currently on a newer chemo treatment due to tumor growth and it's working. My tumors have been shrinking and I am considered "cancer under control".Sadly I will be on a form of chemo for the rest of my life. With Dr. Panares, I should have a decent amount of time left.The only suggestion I have for Dr. Panares is to find a magic wand and to cure my cancer (also all others) and cure my cancer pain. Plus, to use the magic wand to give me back my hair, eyebrows and eyelashes. That would be so nice. Lol!Honestly he's pretty awesome of a doctor. I really trust him!
Providence Patient
Dr Panares was so professional and kind and explained everything to me and he's such a great doctor !!
Providence Patient
This is a thank you noteI have been treated with the utmost respect, knowledge, and care by Dr. Paneras and staff.His concern is not only for my specific concerns as [ID] breast cancer survivor, but for the whole health spectrum of well beingI have come to St. Jude since I was 30 for breast Health, and was first treated by the brilliant Dr. JulianFreeman, a surgeon and breast reconstruction expert. When he retired, I had the brilliant Dr.Petrie for 25 yearsAlmost 15 years ago, I had 2 forms of breast cancer. My oncologist was also brilliant,Dr. Richard LloydAs he has retired, I now have the brilliant Dr. PanaresAs my oncologist I know the cancer center well and consider it a home away from home when it comes to my breast healthI am very grateful that I am still cared for and treated here at age 74Gratefully,[Name(s)]
