Cancer Danger Years: Staying Ahead of the Game with Proactive Medicine

Cancer Danger Years: Staying Ahead of the Game with Proactive Medicine

Cancer danger years: The ages of 40 to 70 are the danger years for many life-threatening diseases, in particular cancer. So how can you reduce the risk to you and your loved ones? You could catch the disease before you even have symptoms by getting a regular whole-body MRI. Dr Zane Sherif explains why this service is so vital.

Myself and my wife Dr Kirralee Sherif (PhD) founded Mermaid Beach Radiology so patients have the power to be proactive about their health, rather than reactive. Getting a whole-body MRI at the right time can mean the difference between life and death. We just had a male patient who was otherwise well, who came in to see us for a general health and wellbeing scan. Himself and his wife just wanted to get checked out, just to stay on top of their health. They said to me, “We service our cars once a year, why wouldn’t we service ourselves?”


They had a full-body MRI scan. No abnormal pathology was found on his wife. But unfortunately, the chap had lung cancer. While this sounds like a total disaster, the disease was caught in its very early stages. He felt great and he was completely asymptomatic. The chap wasn’t coughing. He didn’t have any weight loss. This situation is what we call ‘pre-clinical.’ And this is exactly what a general check with a whole-body MRI is designed for. If he left this health situation until he was symptomatic, he could have had an entirely different outcome. A lot of the time, when you’ve got cancer, you don’t get diagnosed until symptoms like weight loss and other problems become obvious. Often at that point, it can be too late.


Back to our lung cancer patient. Luckily, the cancer was in the very early stages, and was sitting in the middle of his lungs. If he’d left it a few more months, then the tentacles of that cancer could have wrapped themselves around critical vessels, and then it would be inoperable. But, because he chose to be proactive with his health and get our whole-body MRI scan, it was caught very early. From this point, he has many options to treat the cancer. Three months or six months down the track, he may not have had those options. Imagine hearing the words “I’m sorry, sir, it’s inoperable. Chemotherapy might extend your life for six months. ”But if we catch the disease this early on, you may have plenty of options, which could be curative ones at that.

Now, his prognosis is excellent. He’s going to survive this, and likely be cured from it. It was an isolated lung cancer. And again, it was in the middle of his lung, so it wasn’t touching any vessels, and could easily be removed by surgery.

When he was in hospital, he had a PET scan (an imaging test that allows your doctor to check for diseases in your body. The scan uses a special dye containing radioactive tracers.) His oncologist was unfamiliar with our full-body MRI screening.

When we did his whole-body MRI, we saw that there was no cancer anywhere else. His specialist sent him on for a PET scan. The PET scan came back and showed exactly what the full body MRI scan did – there was a solitary lesion with no metastasis, great correlation.


It’s always great to get a second opinion. We are the people to see if you want a second opinion! So, from our point of view, it was good that he got a PET scan. However, it didn’t offer any additional information and he has paid a bit of a radiation cost for that. Whereas the whole- body MRI does not use radiation. It uses magnets to create an image.

Our patient was a smoker. He says he smoked about five a day. Not anymore! He is in his seventies. So the cumulative effect of smoking, even small amounts of cigarettes does creep up on you! This is the perfect person to have a full-body MRI. But there are other people who live very healthy lives, and they still get afflictions like cancer, so regular non-radiation-based scanning is a great option to help get an early diagnosis.



We designed Mermaid Beach Radiology to be small and fabulous. We want to offer the most personalised service on the best imaging equipment science has to offer. Our fleet includes Australia’s only Spectral CT scanner in private practice and the extraordinary research grade Philips Elition X 3T MRI scanner.

A full-body MRI scan using equipment on the very cutting-edge of technology is a great tool to help stay ahead of many catastrophic health issues such as cancer. If you’re relatively well, as in you have no real symptoms, but there’s a strong family history of “badness” in your family, then get that scan. It gives a level of peace of mind. And, it can detect cancer in its early stages and deep pockets of infection. It can show a lot of other things as well, but its primary utility is cancer screening. It’s very accurate.


Full body MRI screening is common in the US. They have many private clinics where you can just turn up and get a yearly scan. We need to start doing that here in Australia. In Europe, Japan and the US, MRI is used to validate with PET and real time imaging during chemotherapy to determine if drugs are working without imposing the radiation that these other scans do.

Even if you are well, it is still a good idea to get the full-body MRI scan. If you already have a disease process going on, we can look at the burden of disease. We can monitor that burden as it gets better, or if it gets worse, or if it’s responding to treatment, or if it’s not. Adjustments in that treatment can follow.



I am a strong believer in proactive health checks. No one will mourn the loss of your motor vehicle.

Whereas there are plenty of people who will mourn the loss of your life if you stop existing. Your kids, your family, your friends, your business partners. Your health is your most valuable asset. You are no good to anyone, impaired, impaled, or dead. So, it’s really about prolonging your life and this is your responsibility, especially if you have kids or other people you look after. Your life is really only partly yours – and mostly your family’s life. I exist pretty much at this stage for my kids. So, my health is of paramount importance to me, because I can’t help anyone if I’m not around. So, why would you get a full-body MRI on a regular basis? You would get it done because you value your health above all else.


There is no major downside to looking after yourself in this way. There’s no radiation. The only downside to this is an hour and a half to two hours of your time and a little bit of money. But from as little as $1500 now, you could save tens of thousands of dollars in treatment down the track for something that could have been caught earlier and more importantly saved you a tonne of misery. It is money well spent.

The reason why people come to us at Mermaid Beach Radiology is not just that we use a three- tesla (3T) research grade scanner, but because the sequences we run are custom written, research enhanced and not commercially available. In America, they often do this scan on a 1.5 T MRI. So we are well ahead of the game here. But also, we have Ben Kennedy on staff. He’s our MRI and Clinical Research Director. He has a master’s degree in MRI from the University of Queensland and he is coding the machines here to do stuff that no one else in the world is doing right now. We have plenty of world-firsts at this clinic because of the machines we use, and the work Ben is doing with them. And, you can’t get this coding anywhere else. This is all highly customised, and it’s all research enhanced.


After age 40 is the right time to start getting regular full-body MRI scans done. Other than childhood cancers, the cancer frequency for people age 20 to 40 is much less than older people. This is because a lot of cancers are from a lifelong toxin exposure. It’s not just one thing that usually causes cancer. It’s a multitude of things. But by the time you’re 40, you’ve had enough exposure to all of this to create the perfect storm. One cigarette doesn’t kill you. But it’s a lifelong exposure to cigarette smoke, to general pollution, chemicals in food, and in the air we breathe. The body is pretty tough and robust, but the peak of cancer starts to show its head by about the age of 40. Of course, there are younger ones, but they tend to be rarer.

There are other things we look for, outside of cancer. Recently a person came in for a full-body MRI scan. We didn’t find any cancer. But we found a large hiatus hernia on her (when your stomach bulges up into your chest through an opening in your diaphragm). So, there’s frequently other incidental pathology that we’ll find. She then said that she wondered why she had a problem with belching and bad breath! Now she knows!

Medicare – as wonderful as it is – has its limitations. If you want to be at the forefront of diagnosis, it is sometimes a user-pays model. But the beauty of this and with MRI in general, is that because you’re paying for it, you don’t need a referral, which is empowering. You can be ahead of the health curve by spending a little bit of money.

If you ever feel like you’re being blocked or not heard, you can say right, stuff it, I’m going to go and get a full-body MRI scan. And then I’ll come back to you with what the MRI finds. Very empowering stuff.



Keep in mind that no one knows your body better than you. You are hardwired to every part of your body. So, when you go to a doctor and you say, ‘this is how I am feeling’ and they say, ‘oh, it’s probably nothing’ – you don’t have to be satisfied with that answer. You can take matters into your own hands. You can drive your own health. The only cost to you is time and money. There’s no radiation or biological cost.


The cost we charge covers a large body of work. It takes about 90 to 120 minutes to acquire the data. It is another 90 minutes to put it all together. And it takes me about the guts of an hour to report it. There’s a tonne of data to sift through. So, it’s a massive body of work. Plus these machines cost millions of dollars, and you are getting access to them and the cutting-edge of diagnostics. So if you look at it as a value proposition, you are getting a great deal.

You don’t have to do much to prepare for these scans. You just have to turn up. Because you are going to be on the scanner for 90 minutes, we would just discourage lots of drinking of water or caffeine. You don’t want to fight the urge to go to the bathroom in the middle of the scan!

All you need to know is that you have to put your health first – nothing is more important.

Cancer Dogs: Can Our Canine Friends Sniff out Cancer?

Cancer Dogs: Can Our Canine Friends Sniff out Cancer?

Cancer Dogs: It seems that our fur babies are our new weapon. Doggos to the rescue!

A team of scientists has proven that dogs can truly sniff out cancer. And this canine cancer detection could lead to new non-invasive, and inexpensive ways to detect the disease. Good dog!


Dogs that detect cancer may sound like science fiction. But the good news is that this could be the most exciting discovery in the cancer field for decades.

A dog’s nose is an exquisite piece of machinery, capable of smelling in parts per trillion. This makes dogs highly sensitive to odours we can’t even dream of smelling. If it was sight we were talking about, it would be like this: What you and I can see at half a kilometre, a dog could see at 5000 kms away, and see just as clearly. It’s impressive stuff.

Heather Junqueira is the lead researcher at BioScentDx. Her team are currently working to see if dogs really can spot cancer. For the study, Junqueira and her colleagues used a form of clicker training. They taught four beagles to distinguish between normal blood serum and samples from patients with malignant lung cancer. One beagle – named Snuggles, of course – couldn’t be convinced to stay on task, the hippie. But, the other three dogs correctly identified lung cancer samples 96.7 percent of the time. Aww cancer dogs, who’s a good boy!

“This work is very exciting because it paves the way for further research,” said Junqueira.

We should suck up to beagles, really really fast. Well, except Snuggles. All we can do with that guy is snuggle.

Junqueira isn’t the only scientist that’s getting results like this. Recent research has shown that dogs have detected lung cancer, melanoma, breast cancer and bladder cancer. While more study is needed, the initial results are incredibly exciting.


It isn’t just in the lab that dogs are showing their ability to pick up cancer. There are many incredible stories of dogs detecting cancer in their owners, including a story about a dog called Max from BBC’s Secret Life of Dogs.

Max is a Red Collie Cross normally full of energy and enthusiasm, but his owner Maureen Burns noticed that something was wrong. “I thought at the time Max was fading. He was nine and a half and I was preparing myself for losing him because he just wasn’t happy. He would come up and touch my breast with his nose and back off so desperately unhappy. There was such a sad look in his eyes.”

Maureen knew she had a small lump in her breast but her latest mammogram was clear. So she presumed all was okay. “But soon, I connected it with the dog and his odd behaviour.”

Maureen went to her local hospital but both a scan and a mammogram came back negative. It took a surgical biopsy to finally detect the cancer. Maureen had it removed and the change in Max’s behaviour was instant. “When I came home from the hospital, he was his old hyper self again. He put his nose across my breast to check where the operation had been. His eyes were happy and the change in him was instant. I owe Max so much. Now, before I go for a check-up, I get him to check me out. If he’s happy and wagging his tail, I am happy.”


Likewise, actress Shannen Doherty has battled cancer more than once in her life. In an interview with Entertainment Tonight, she told an extraordinary story – that her dog identified her breast cancer before doctors could diagnose it. And interestingly, her story isn’t unusual. There are thousands of stories that are very similar to Shannen’s.


Many teams around the world are trying to work out how they can use dogs in cancer diagnosis. Dr Gianluigi Taverna is a researcher with Humanitas Research Hospital in Milan. He showed that his dogs could detect prostate cancer with an amazing 98% accuracy. Taverna and his team spent five months training two German Shepherds to detect cancer in humans by sniffing patients’ urine samples. The dogs checked over 900 people in the study. Out of these 900, the dogs were only wrong 20 times.

Said Dr. Taverna, “We have demonstrated that the use of dogs might represent a real clinical opportunity if used together with common diagnostic tools. Our standardised method is reproducible, low cost and non-invasive for the patients. This might reduce unnecessary prostate biopsies and pinpoint patients at high risk for prostate cancer.”


Dogs are already used to detect impending seizure activity, and also to help mitigate meltdowns in people suffering from autism. The ability to detect cancer too means that dogs are not only amazing companions and our best friend – but could also save our lives.

Of course, there is a stack of research still to be done. But the future in this area is very bright. There are organisations which are springing up whose sole aim is to train cancer-sniffing dogs. One of these is the InSitu Foundation ( They rescue dogs on death row and give them a new life, where they are loved and cared for.

Cancer-detecting dogs could be an amazing weapon against one of the biggest health scourges of our time. We knew we loved dogs for a reason, now there is a whole new reason to love them! Come sleep on our beds forever, doggos!


Hero Linus doing his work

This special guy, called Linus, is a 3-year-old male German Shepherd who was on death row. He was returned to a shelter three times by his previous owner. The InSitu Foundation adopted him. When he came to InSitu’s ranch, he got his first job, and it literally transformed Linus’s life. Linus went from a small jail cell to a life of love and play. Says InSitu, “He’s happy, balanced, and well adjusted, and he’s the most loving boy around! Linus loves his work, and he’s a gem on the cancer detection team.”

Linus also works on the Duke University team of breast cancer detection dogs. Read about more cancer-sniffing dogs at
