"This was my 4th time at the clinic for my annual thermogram. The atmosphere is very calming. I was met by Nazret who immediately put me at ease and explained the procedure..Once again the whole process was conducted very professionally and all questions I asked were either answered either immediately or also emailed later to me.I highly recommend an appointment for piece of mind."

Having attended The Natural Doctor's Clinic on 3 occasions over the past few years for Breast Thermography Screening, followed by consultations with Dr Eccles, I wholeheartedly recommend this great service for women.If, like myself, you prefer to use an alternative to Mammography for breast screening, Thermography is a great, non-invasive, pain-free method of identifying early on any areas of potential concern. My experiences with the Clinic have all been very positive. The pre and post-appointment communication is very thorough and helpful. The clinicians that carry out the screening have been personable, kind, attentive women, who put you at ease during the procedure. And with Dr Eccles you are in safe hands; he is approachable, amicable whilst highly professional; he clearly cares about his patients and getting the best outcomes for you, using natural therapies and supplementation, and I thoroughly endorse his Thermography service.

I had my first thermocheck with Nazret on the 18th Feb 2026.I was made very welcome at the clinic , Nazret was very patient with me as I was a bit nervous and unorganized! She was professional, helpful and knowledgeable.

Just been for my annual breast thermography at the Natural Doctor. Always a delight - the technicians that do the scans are all lovely and you know you are in safe hands. Such. a good way to take care of your breast health - non-invasive and picks up any problems in plenty of time to put things right before they get serious. Highly recommended.

Honestly it feels strange to say this, but it was such a lovely experience from beginning to end!I was looked after my the lovely and incredibly tentative Nazaret (apologies if I have spelt this incorrect) after experiencing breast appointments elsewhere which have left me wary, it’s safe to say that today restored my confidence and I took great comfort knowing this service is so well thought out and accessible to all 💫⭐️✨🌟Thank youClaire 😊

Thank you so much to Katia at The Natural Doctor for her outstanding service during my thermo scan. I couldn’t have been treated any better, she was professional, kind, and made the whole experience so comfortable.

I booked in to have my repeat follow up breast thermography scan, as always I was met by a lovely female scan technician who immediately put me at ease and answered any questions I had thoroughly and sensitively. I thoroughly recommend Dr Eccles and his team for anyone wanting to have a painless, safe and accurate alternative to a mammogram.

I've been having these thermal breast scans (breast thermography) since 2008. It's a quick and easy treatment as well as comfortable and non-invasive, and it gives me peace of mind knowing it's safe and has no bad side effects like radiation. I also like to be proactive and know what's happening in my body on a regular basis so I can deal with it promptly if necessary. The staff has always been very friendly and helpful, so the whole experience is a pleasant one.

After suffering Breast Cancer 6 years ago I knew I had to be in charge of my own breast health .So after searching I found Dr . Eccles and he's changed my whole life approach to breast health .I now feel reassured and can get on with my life knowing I'm doing everything I can to stay healthy .I highly recommend Dr.Eccles and his team . They make you feel really comfortable throughout.

Absolutely great service, been going for a number of years now, for the thermographic breast imaging. Staff is very professional and very kind and observant at the same time. Results come through within a couple of days.Would continue to use this service as an alternative to mammogram, for as long as the clinic is there.

I have found all the staff to be helpful and understanding.A pleasure to deal with.My consultation with Dr Eccles was not only informative medically speaking, but he also tried so hard to find a solution to my problems. At the end of the consultation, I felt much calmer. I really felt as if he were 'routing' for me. I am most grateful.

Always a delight to pay a visit to the Natural Doctor. He's currently the only doctor I trust. Genuinely concerned with people's health. I've been having regular thermal scans for years, having been pegged as 'at risk' for breast cancer. All the ladies that do the scans are lovely and you know you are in safe hands with his advice on how to put things right if they look a bit dodgy - the scans pick up any problems way in advance of anything serious. A no-brainer for me.

The Dr helped me feel like myself again after lots of low level symptoms. My GP dismissed me. It was worth every penny. Thank you

Dr Eccles has given me my life back, because he has balanced my hormones in a way that enables me to live my life to the full again!I was not only suffering with menopause fatigue and the many other symptoms of menopause, but I had ongoing lethargy with Auto-Immune Hashimotos and a struggling thyroid. It came to the point I didn’t know which symptom was due to which hormone deficiency.After my second thorough consultation with Dr Eccles, he had tweaked my dose and found I was indeed Iodine deficient. Now I am beginning to have normal levels of energy again and it is getting better and better, for the first time in five years! I sleep like a baby and my overactive bladder has been calmed. I am so glad I found Dr Eccles, life is too short to suffer with debilitating symptoms, he is the best doctor for me!

I began to see Dr Eccles six years ago and he continues to provide excellent care and attention every time I see him. I have referred several friends to him and they have all been very happy. Both Dr Eccles and his staff genuinely care and always go the extra mile. I highly recommend him for all areas of female health, immunity and healthy ageing in general!

Been visiting this clinic for nearly 10 years. It reassures me about my breast health and if I raise any concerns they are always answered well. Staff are professional but friendly. Dr Eccles knows his field. Will keep returning for my check ups. Peace of mind is worth so much.

A recent breast health scare in my 30's lead me to seek a less invasive option to check breast health. The Thermocheck scan, detailed report and Skype consultation with Dr Eccles was very professional and reassuring. I now feel more informed and supported in preparation for my hospital appointment. I highly recommend Dr Eccles and his team to provide an efficient, professional service and support your health naturally.

Thank you for giving me the opportunity to use your excellent product. Although it has only been 2 weeks, both myself and my wife have noticed, the hair growth has certainly become thicker, more of a covering. This is very encouraging, following many years of not really being bothered about my hair loss, now that I am noticing an improvement I am very excited at the prospects of once again having a full head of hair.
