She emphasizes comprehensive screening rather than relying on any single test.

Hey, it's J.J. here. You know, I've been talking about environmental toxins forever, and laundry detergent is a sneaky one. A lot of them contain harsh chemicals like dyes, preservatives, and even UV brighteners. Those brighteners don't actually clean anything. They just coat fabric so your eyes think things look whiter or brighter. That's more chemicals I don't want on my family's sheets or skin. And if you've got sensitive skin or allergies around the house, this can be a big problem. That's what got my attention about Earth Breeze. It looks like a dryer sheet, but it's actually laundry detergent. You toss one in the washer and that's it. No pouring, no mess, and no heavy plastic jug.

I will tell you that the average doctor is about 12 to 15 years behind. What's existing in a textbook or a conference will not be regular standard of care for about 12 to 15 years. So doctors need to constantly be in front of science because it's changing every minute and something new is coming out all the time. So we as integrative functional medicine doctors need to know what the best testing the best care for the patient because it's constantly changing. So I will tell you when I first see the patient I do a very thorough assessment and an understanding of their health, all their health before birth. Because things can are very very important in assessing what you're going to order for the patient. So the first thing I do is a comprehensive blood testing that is available in any laboratory in the United States. So most important is doing a comprehensive testing of all your organs, your blood count, your thyroid function. Do you have Hashimoto's? Is your sugar high? Do you have inflammation levels, vitamin D levels, DHEA sulfate, adrenal levels? Is your liver functioning right? Because your liver is your purifier. So we want to do a comprehensive assessment. Then I have the there's a blood test called the cancer profile that will it's basically a combination of hcg which the hormone of pregnancy. Then we have it checks your DHEA sulfate. It checks an enzyme of low oxygen. Remember, low oxygen is an environment for cancer called P H I. It will check for C reactive protein, liver function and a non specific marker called C E A that is common in many cancers. Then we have the RGCC test which is the liquid biopsy. So if you've had cancer before, you definitely want to do this test to look for the circulating tumor cells which are responsible for 95% of metastasis. But you also could do that prevention as a liquid biopsy. This is a test that I love and tremendously helps me identify an existing cancer or a cancer that you've already had and you need to deal with the circulating tumor cells. Then I do thermography because thermography is a non invasive, non injurious process to examine not only your breast but any part of the body. So it will detect imbalances in the anatomical environment of the body. Then we can also do PET imaging. Sometimes I have to order PET imaging MRIs. We do lots of ultrasound ultrasounds and non invasive testing that can do test thyroid cyst on your thyroid, something wrong with your liver, your kidney, your spleen, your pancreas. Also can check for anything abnormal in the pelvic area, maybe an ovarian cyst, maybe a fibroid or any other kind of masses, but there's no radiation. And then we have CT scans. So all of these imaging can also detect lumps and bumps. Now, as you know, cancer starts way before a lump and bump appears. And then we have something that I've been using for over 20 years called bioenergetic testing. You have to understand that your entire body is energy. Every cell emits energy. So we check the acupuncture meridians, which have been known for over 5,000 years. And we check the healing imbalances or the energy blocks in the body and identify things that we can't find in a blood testing or thousands of dollars of sophisticated testing. So I can send you these six tests with more elaborate understanding if you would like.

Every week I tag all Things Books and Reading with a guest and guide them in discovering their next read. They share three books they love, one book they don't, and what they've been reading lately. And I recommend three titles they may enjoy reading next. Guests have said our conversations are like therapy, troubleshooting issues that have plagued their reading lives for years and possibly the rest of their lives as well. And of course, recommending books that meet the moment. Whether they are looking for deep introspection to spur or encourage a life change, or a frothy page turner to help them escape the stresses of work, school, everything. You'll learn something about yourself as a reader and you'll definitely walk away confident to choose your next read, with a whole list of new books and authors to try.
