Honest Thoughts on Integrative Cancer centers

Did anyone attempt getting care at an integrative cancer center like Hope4Cancer or Oasis of Hope? How did that go for you? Is this something anyone looked into or has thought about even as a last resort? Or is it really just a money grab? I’ve heard conflicting things. Some say it’s helpful for healing, but these were people with different cancers. I see other stories online that I’m not so sure about with these places. This is not for me as I’m a caregiver. But my spouse is considering it. I’m not so sure. I feel like I need to hear from people with experience or insight. Thank you in advance.
