Health24.com | 3 random things that can mess with your mammogram results

Do you stick to your annual check-ups? Your yearly mammogram after a certain age?

“Early detection saves lives.” This mantra – the crux of countless public service announcements and awareness campaigns around cancer – is as encouraging as it is empowering.

Plus, underdiagnosis remains a problem in SA, where cancers are often caught too late.

But at the opposite end of the spectrum, another issue is on the rise: that of overdiagnosis. As technology advances, science can now zoom in on miniscule flaws that make cancer detection a murkier matter.

Take mammography…

If five women over the age of 40 were to get mammograms, one of them would be saved from dying of breast cancer.

But another three could be called back for additional testing for a “false positive”, something that looks like cancer, but turns out to be harmless: a cyst or calcium deposit, benign tumour or dense tissue.

This phenomenon is being called overdiagnosis and, in recent years, it has morphed into a lightning rod due to the collateral damage it can cause: patients are exposed to the cost, emotional turmoil and side effects – some of them life-threatening themselves – of unnecessary surgery, chemotherapy and radiation.

Unlikely things can make mammograms more difficult to read – or throw off the results altogether.

Here are three common things that can also mess with your mammogram results in a pretty substantial way:

1. Breast implants

Saline or silicone fillers can make it tricky to see certain parts of your breast during imaging. Ask your doctor to refer you to a clinic with experience reading scans of women with implants.

2. Tattoos

In rare cases, tattoo ink can look like a cancer that has spread to the lymph nodes. Make sure your doctor and radiologist know if you have skin art anywhere on your body.

3. Deodorant

Some antiperspirants contain substances that can show up on a mammogram as white spots. Skip it the day of your test.

These four factors could all cause a pregnancy test to be wrong. Plus: Here’s exactly how to skip your period every month.

Apple TV 4K Review

Apple TV has, we think it’s fair to say, had a bit of a tough time in the past.

It was a product that at times felt a little slow to adapt in a very fast-moving market that has seen two brand-new technologies appear in quick succession: 4K and HDR.

While TVs had started adopting Full-HD, Apple’s first TV supported only 720p. When it finally added Full-HD, it was clear that 4K resolution TVs were going to be the norm very soon.

Rather than dive head first into this new technology Apple did what it has so often done before, it waited.

While this might make perfect business sense, it was frustrating to reach a point where you could watch Netflix in 4K but not any of the films you’d bought or wanted to buy from iTunes.

The new Apple TV 4K is here to rectify this and while it has taken Apple a while, the results speak for themselves.

Apple

In design it looks identical to the last model. It is a sleek, minimalist black box that’s both wonderfully subtle. It’ll look just fine anywhere you put it and that’s important, because more often than not it’s going to be in your field-of-view every time you sit down.

Inside there’s some new-and-improved hardware. There’s the A10X Fusion processor that originally debuted on the iPad Pro. This gives the Apple TV an absolute bucketload of power for gaming.

Finally there are two storage sizes: 32GB and 64GB. These will be used for downloading games and apps. The rest of the content you’ll be experiencing will come via streaming.

Apple

The remote has been given a subtle update too with a little white ring around the Menu button making it easier to orientate yourself in the dark. It’s also cheaper now to replace, which is always good news.

The glass directional trackpad is still there and it still remains a bit of a faff to use if we’re honest. The remote charges via Lightning cable so that’s handy and the battery life is absurdly good so it’s very rare that you’ll actually have to charge it.

Where the Apple TV 4K really starts to shine is actually when you turn it on for the first time and experience Apple’s operating system, tvOS.

If you have an iPhone setup is astonishingly simple. You simply tap your iPhone onto the Apple TV and it transfers everything it needs including your iCloud login details, it will even send over the WiFi password.

It’s such a small thing and yet it’s hard to emphasise just how big of a difference it makes.

HuffPost UK

The main menu is beautifully rendered in 4K and a breeze to get around. As before the stunning slow-motion screensavers are back and yes they’ve all now been shot in 4K.

You can download apps such as Now TV, BBC iPlayer, Netflix from the App Store or if you’re tied into Apple’s ecosystem then there’s easy access to your photos, Apple Music and TVs and Movies.

HuffPost UK

It is this last point that deserves the biggest mention here. Apple now offers 4K and HDR movies on iTunes. This is a big deal not only because of Apple’s sheer size and reach but because unlike physical copies or other digital stores Apple will not be charging you a premium for 4K/HDR films. Instead they cost exactly the same as everything else.

HuffPost UK

If that wasn’t enough, Apple will also upgrade any of the films you previously own to a 4K version for free if it has it in its library. There’s no downside here.

While 4K has been adopted by TVs and by companies like Netflix and Amazon Prime Instant video, it has up until now been difficult to compile a digital collection of 4K films that can all reside in one place and that can exist across multiple services. Apple TV feels like the first product that actually makes this a convenient reality.

So how does 4K HDR content look on the Apple TV? Well unsurprisingly, it looks fantastic.

If you’re someone who’s big on their AV specifics then you’ll be pleased to know that Apple TV supports both HDR10 and Dolby Vision, the two main competing HDR technologies.

Apple’s streaming technology has always been superb and as long as you’ve got a pretty decent internet connection there’s very little wait between pressing play and the content appearing up on screen.

We say “decent internet” because we did find that when our speeds dropped below 20mbps the loading screens did take longer, and on some occasions we even had playback stop momentarily. If you can maintain a steady connection of around 15-20mbps+ however you should be absolutely fine.

There are some other more specific AV hiccups at this point. Apple TV doesn’t support Dolby Atmos. For those of you who haven’t invested a small fortune on a surround sound system this is a new audio technology that allows films to be played with an almost complete 3D surround sound. For the majority of users this won’t be a big deal, but if you’ve spent eye-watering sums on a home cinema setup it’s something to consider.

It also, and this is a biggie, doesn’t support YouTube in 4K HDR. That’s unfortunate because at the moment, the largest library of 4K HDR content on the internet is on….YouTube.

There’s no word on when or even if Apple will ever support YouTube at this resolution and it’s actually something that’s plagued Safari on both Macs and the iPhone. It’s annoying not least because all of its competitors support it, but also because it just doesn’t seem to make any sense.

HuffPost UK

One feature that does have a welcome home on Apple TV however is Siri. It’s incredibly accurate at voice searches and can even really drill down into some very specific questions if you want to something super niche. You can ask for genres, sub-genres, films with 4K, films with only HDR, or even films from a certain year.

HuffPost UK

Finally there’s the content ecosystem itself. If you search for something Apple TV will try and accumulate all that content across the different services you use, whether that’s Netflix, iTunes or BBC. It’ll then let you play it straight from the Apple’s own menus, without then having to go back out and open specific apps.

Apple TV does support gaming, and there are a whole range of simple, often very beautiful-looking games that can be great time-wasters. If you’re keen on gaming it’s not going to replace your games console, but for everyone else there’s plenty here to enjoy.

Apple

As before however, it’s not all perfect. For starters there’s no dedicated Spotify app, and while it supports Spotify through Airplay it would be nice for there to be a dedicated app that lets you search and play direct from the TV.

Secondly, at £179 this is definitely a premium product. Chromecast Ultra costs just £69 and while it’s arguably more limited in what it can do it is a full £100 cheaper. Then there’s the NVIDIA Shield TV, which for £179 supports both 4K and Dolby Atmos. Of course neither of these can offer iTunes, Apple Music or any of Apple’s ecosystem apps.

It’s that last point then that really makes you realise who the Apple TV is for and why it’s so good at what it does. If you’re already heavily tied into Apple’s family of products and services then Apple TV is a joy to behold. Yes it’s bound by its exclusivity to Apple’s own products, but rather than feeling closed off, it offers people who like that ecosystem the perfect accompaniment for their home.

Who should buy the Apple TV 4K?

If everything in your digital life is firmly placed in Apple’s iCloud then Apple TV is a no brainer. 4K HDR content is finally reasonably priced and it looks absolutely stunning. There’s just about every app you could need available and the operating system is easy, intuitive and extremely powerful.

Who shouldn’t buy the Apple TV 4K?

It’s an Apple-centric product which means that it only really comes into its own if you’re quite heavily invested in its products and services e.g. Apple Music, iCloud, iTunes etc. If you’re an Android user, or not heavily invested in Apple we would absolutely recommend Google’s Chromecast or NVIDIA’s Shield TV if you really want the absolute latest audiovisual technologies like Dolby Atmos.

Apple TV 4K is available now in 32GB and 64B sizes priced £179/199 respectively.

Doctors Have Found A New Way To Fight Cancer

Doctors in the United Stated have found a new way to fight cancer by taking a more detailed look at a tumour’s DNA. 

A panel of doctors, termed tumour boards, asses the patient’s cancer genes and mutations and prescribe drugs that match the mutations.

Alison Cairnes’ whose cancer had spread from her stomach and oesophagus to her liver, lungs and lymph nodes tried this new approach.

Health24.com | How a genetically skinny guy can build muscle

I’ve been called a pencil, a string bean, skin and bones. I’ve heard the three words no man who cares about his physique ever wants to hear: “You work out?”

Trainers refer to us as ectomorphs – which sounds like something from Ghostbusters – to distinguish us from mesomorphs, the guys who always look like they work out even when they don’t.

My fellow ectomorphs and I prefer to call ourselves “hard gainers”. We brush off the insults, chalk up our physiques to high metabolism and take solace in the fact that some of us are good at endurance sports.

At least that’s what I used to do. Then I had my Charles Atlas moment. But it wasn’t a sand-kicking bully who made me want to become bigger and stronger. It was a former girlfriend who wanted to hire movers to carry her furniture into a new apartment because she was afraid I’d hurt myself if I tried to help.

I knew it was time to build strength and muscle. But before I could, I had to demolish five of the myths that hold skinny guys back.

Myth 1: An ectomorph can’t gain muscle

I almost puked during a test of my maximum bench press. Martin Rooney, C.S.C.S., director of the Parisi Speed School in New Jersey, US, explains why: “Lifting weights is a stimulus. It attacks your body – everything from your muscles to your nervous system,” he says.

“That was your body being challenged in a way it’s never been before. It isn’t used to that kind of stress. Now your muscles will rebuild and prepare for the next attack.”

I’d need it: That first workout was humbling. At 6 feet tall and 66kg, I could deadlift just 47kg and bench press 43kg only three times. I could do 11 chinups, which isn’t bad, and my 11.5% body fat would be the envy of many mesomorphs if they weren’t already laughing at my upper-arm girth or my wimpy 50cm vertical jump.

Rooney assured me that building up from this shaky platform would be difficult but not impossible, as long as I was willing to push myself.

“Your body is an incredibly adaptive organism,” he says. “That’s why every time you lift, you have to challenge yourself to provide a greater and greater jolt to shock your muscles into another round of rebuilding.”

Myth 2: No matter how much he eats, a hard gainer can’t put on weight

If you think you eat enough to build muscle, try this experiment, courtesy of Alan Aragon, a nutritionist and Men’s Health advisor.

Pick a recent day that represents how you typically eat. Try to remember everything you consumed and run it all through a kilojoule calculator.

If you’re like me, you’ll see a problem. I estimated that I ate about 8 368 kilojules a day, but it was really more like 7 000 – nowhere near what I needed to maintain my existing muscle mass, let alone add to it.

“Underweight people tend to overestimate their daily kilojoule intake,” Aragon says. “Then they incorrectly attribute their low weight to a high metabolism.”

So kilojoules matter. But so do the sources of those kilojules, Aragon says. More food means higher levels of glucose circulating in your blood. That creates metabolic stress, leading to inflammation, and inflammation can lead to a whole host of problems, including cancer and cardiovascular disease.

So trying to build a more muscular body with junk food is like trying to build a log cabin with wood drenched in lighter fluid.

Aragon directed me towards whole grains, which provide fibre that may help regulate blood glucose, and foods rich in antioxidants and omega-3 fatty acids to fight inflammation. But I still dreaded the answer to my next question: How much will I have to eat?

Myth 3: He has to eat till he bursts

Aragon’s nutrition plan called for 10 460 kilojoules on workout days, including 213g of protein. That much protein amounts to a kilogram of raw sirloin or 34 large eggs!

I had trouble stuffing it all down at first. It took me a half hour to finish breakfast, and my lunches in the company cafeteria horrified my coworkers. Soon I realised I couldn’t consume all my kilojoules in three giant meals.

So I adapted: I kept a jug of almonds and a bunch of bananas at my desk for snacks. I stored a block of cheese and a gallon of chocolate milk in the office fridge.

“Your body will tell you how it best processes calories,” Aragon says.

“For some people it’s large meals. For others it’s around-the-clock eating. If you time it right, you should rarely feel as if you’re force-feeding yourself.”

 Myth 4: He must live in the gym

Each week I worked out four or five days, training for up to six hours total. But if I felt physically or mentally drained, I skipped a workout or two.

“If your body’s sore, it’s telling you it needs more time to recover,” Rooney says.

I’m convinced that the extra rest time enhanced my results, giving my body the time it needed to recover and to come back stronger.

Myth 5: Results will be minor

I won’t lie: It can be tough, especially in the first few weeks. Some days I was so sore I wanted to avoid walking up a flight of stairs. And the results are unpredictable. You may gain a few kilos right away or you may lose a kilogram or two because of the radical change in your routine.

But once you’re past the shock stage, you should see steady growth. “Beginning lifters can expect about 1kg of muscle growth a month,” Aragon says.

Key point: Each time you hit the gym, give your best effort. “You may think it’s just one rep you’re missing, but that last rep is when your muscles are working hardest,” Rooney says. “The question isn’t whether you’re a hard gainer, but are you a hard trainer?”

Rooney retested me about four and a half months after my first visit. I deadlifted 114kg, and my three-rep max on the bench press jumped to 75kg. I cranked out 20 chinups, and my vertical leap soared to 67cm.

That’s in addition to the 6.3kg I gained. And it may not sound like much, but I added 5cm to my biceps. My waist was still 81.2cm and my body fat actually decreased to 9.8%.

But the sweetest reward wasn’t measured with a barbell or tape measure. A friend mentioned that she was moving to a new apartment and asked if I could help with the furniture.

“No problem,” I said. And it wasn’t.
