David Hibbitt, from from Stoke-on-Trent, was diagnosed with the disease in July 2012 after initially being told he was simply suffering from piles. Despite undergoing chemotherapy, radiotherapy and surgery to remove his large bowel, he says doctors told him he was terminal. In desperation, he went online to research his options - and decided to try cannabis oil as a last resort, buying some from a local dealer for £50 a gram. Now the father-of-one says he has been cancer-free since his last scan in January - and puts the class-B drug down to his miracle recovery. Today, he will finally marry his fiancé Heather (inset). He said: 'I just want to make other people aware that there are other options out there.'

Sisters Yogita Rameshbhai Nandwana (left), five, and Anisha (right), three, and their 18-month-old brother Harsh (centre), are among the world's heaviest young children. Weighing 5st 5lbs, 7st 8lbs and 2st 5lbs respectively, the food they eat in a week is enough to feed two families in a month. Now their father Rameshbhai Nandwana, 34, of Gurjarat, India, is planning to sell his kidney to earn the money needed to see top specialists. The siblings are also pictured with an older sister and their parents (inset).

Some apparently healthy meals are worse for you than demonised junk foods from the likes of McDonald's, Burger King and Pizza Express, researchers have found. For example, Asda's Piri Piri Chicken Pasta Salad contains 46.5g of fat - two thirds of the recommended daily intake for an adult - which is more than the 43.3g found in a Burger King Bacon and Cheese Whopper. Meanwhile a Marks & Spencer Chicken and Smoked Bacon Salad sandwich contains 694 calories and 37.1g of fat - but a Pizza Express Classic Margherita pizza has 683 calories and contains only 22.5g of fat.

Amelia-Jane Harris, 20, from Birmingham, was bullied for being overweight at school, given the nickname 'Fatty Bum Bum' (she is pictured, left, when she was overweight). She weighed 27st 10lbs and dreamed of losing weight so she could wear skimpy outfits. But at 17 years old, she began vomiting and losing weight rapidly. She consulted her GP, who diagnosed her with Crohn's disease, which causes inflammation of the bowel. In the following years, she lost 18 stone and shrank to a size 6 (she is pictured, right, after her weight loss). Her hair, eyebrows and fingernails fell out and she became so tired she cannot work. And while compliment her on her new slim physique, she grieves for her former curves and wishes she could eat normally again. She said: 'I know it sounds unbelievable, but I'd give anything to be 27 stone again'.

The US-based woman, who has chosen to remain anonymous, was only diagnosed with acquired savant syndrome, a rare brain condition which is only known to affect around 50 people, after undergoing a year of tests. The condition, which is thought to occur after a person suffers some kind of severe head trauma, causes the development of advanced musical, mathematical and artistic abilities, which sufferers are thought to maintain for the rest of their lives.

Danielle Davies, 21, from Morecambe, Lancs, gave birth to son Harley last Friday and he is already wearing clothes aged 3 months. He weighed 11lb 5oz at birth and was too heavy for hospital scales.

Nancy Tucker, 21, from west London, (right) has written a book about her all-encompassing battle with anorexia. The student, who's about to take up a place at Oxford University, developed the disease at aged just 11, having felt she was overweight as a child (top left). The book documents how she would regularly hide food and deceive those around her into thinking she was eating. At her lowest point (bottom left), she survived on water and diet drinks. While the author says she'll never be recovered, she's hoping she now has the motivation to control the disease.

Emma Hannigan, 42, from Bray, near Dublin, left, was diagnosed with the faulty gene, which increases a woman's chance of breast and ovarian cancer, in 2005. The following year she opted to have a double mastectomy and oophrectomy to reduce her risk of developing the disease. It is estimated a preventative mastectomy reduces a woman's risk by 90 per cent. But, for Mrs Hannigan, it was not the case. At the age of 33, she was diagnosed with breast cancer, in 2007. Since then she has battled the disease nine times, including four bouts in one year, undergoing chemotherapy and radiation, right.

Lingerie model Sarah Stage, 30, pictured left one day before giving birth, and right two days before the birth, welcomed James Hunter into the world on Tuesday afternoon. Despite her critics' claims that the Los Angeles resident's unusually trim figure could be damaging to her unborn child, their fears were unfounded. Her son weighed a healthy eight pounds seven ounces and was 22 inches long at the time of his birth.

Beth Hall, 24, from Cambridge, plummeted to a tiny 4st 13lbs after battling the horrific eating disorder since her teenage years. Tormented by bullies at school, she began a strict diet regime at the age of 16, living off nothing more than black tea and coffee. Determined to lose weight, she would often go for up to three days without eating a single thing. But after years of turmoil, she was finally admitted to an eating disorder clinic. And after making a full recovery, she is now a healthy size 8 and studying graphics at university. She said: 'It has been a massive relief for everyone that I have been able to get my weight under control and that I'm a healthy size 8. I know my illness will always be there but I know how to deal with it all now. I hope other girls who read my story are able to gain hope from everything I have achieved. There is always help available and despite how isolated you feel things will get better and you can overcome an eating disorder.'

The reality star tweeted his followers thanking the anonymous donor who stepped in to help save his mother Kim's life. The reality star was left heartbroken last August when doctors revealed his 'best' friend' and mother Kim Norris had just one hope for survival - a stem cell transplant. Weeks earlier the dental receptionist was diagnosed with acute myeloid leukaemia. Overcome with emotion, Bobby, tweeted: 'Somewhere there is an amazing person that registered with @AnthonyNolan and was a match for my mum, I will never be able to thank you enough.' Kym is now back at home while she recovers from the procedure, which took place at UCL Hospital.

Nikki Kelly, 24, from Bridport, Dorset, believed she had period cramps and kept needing to go to the loo. But she was shocked to find she was actually in the early stages of labour, and gave birth to her son James on the bathroom floor (mother and son are pictured, right). She had kept her size 8 figure throughout her pregnancy (she is pictured, left, on holiday with her partner Aaron Swallow, 27, when she was unknowingly four months pregnant). She had been on the contraceptive pill and had even had her period throughout her pregnancy. While she experienced no cravings, looking back she now remembers she had been 'off' alcohol. While Miss Kelly and her partner say the pregnancy was unexpected, they have now put in an offer for a house so the three of them can live together as a family. She said: 'It's the best thing to happen to us. James is our little miracle.'

So when Marie, 23, finally lost her battle with the degenerative disease on April 8, her mother Margaret said she knew her son's death 'wouldn't be far away'. After being given the devastating news that his beloved sister had passed away, John died on the morning of Saturday April 11 - just three days later.

A Houston couple have welcomed the nation's first ever all-girl quintuplets. Proud parents Danielle and Adam Busby and big sister Blayke met (from left to right, Riley Paige, Olivia Marie, Hazel Grace, Ava Lane and Parker Kate) last week for the first time after a straight forward C-section. Delivered in only four minutes, the girls took four minutes to come into the world and its the first time the world has seen all-girl quintuplets since 1969. 'We are so thankful and blessed,' said Danielle Busby to KHOU. 'And I honestly give all the credit to my God.

Shanna McCormick, 31, from Manchester, weighed nearly 28st and doctors said she would die if she didn't slim down (she is pictured, left, before her weight loss). She was suffering life-threatening asthma attacks, and sometimes her partner, Dan Dimmock, would wake up in the night to check she was still breathing. They wanted to get married but Miss McCormick was worried she might not live to see the wedding day. She decided to embark on a two year weight loss plan and managed to shed 16.5st in weight through swapping takeaways for a calorie-controlled meal replacement plan. Now, she is a size 12 (centre) and her and her partner plan to get married imminently (the pair are pictured together, right). Commenting on her weight loss, Miss McCormick said: 'I loved being able to shop anywhere I wanted but what I really loved was seeing the peace of mind it gave Dan. It was worth all the hard slog. And looking in the mirror at the new slender me was a joy.'

Natasha Jackson, 24, and her younger brother, Patrick, 22, were both left with cerebral palsy and brain damage after complications during their births. Paula McKay was told her daughter Natasha had suffered brain damage and would be left disabled after errors were made by medics at the former Sharoe Green Hospital in Preston. When she became pregnant with her second child, less than two years later, she was reassured the same mistakes would not be repeated. But the promise was an empty one. When Patrick was delivered at the same hospital, the same errors were made, leaving her son brain damaged and severely disabled like his older sister. Ms McKay, from Leyland, near Preston, has been awarded £13 million in compensation, a £7 million care package for her daughter five years after a £6 million sum for her son's lifelong care was agreed.in Preston.

Dr Andy Dowson is, in his own words: 'not a big fan of the sun'. He'd rather sit in the shade than lie out in the heat. 'I don't go to hot places.' The leading headache specialist, 54, got skin cancer, and says even a British bucket and spade holiday poses a risk to the disease.

Annegret Raunigk, 65, is weeks away from giving birth to children no 14-17, thanks her daughter Leila, nine, wishing for a younger sibling - and she is now getting four all at once. The primary schoolteacher from Spandau, Berlin, is 21 weeks pregnant - but there are major fears that the health risks for her unborn quads will spike massively if they are induced early.

Rebecca Exton-Russell, 37, was formally a size 18 and posed in campaigns for major brands including Marks & Spencer, QVC and Dove. But the Derby-based model, pictured before her weight loss (left and centre) and after (right), was secretly 'repulsed' by her body, so she checked into a military-style fitness camp and lost three stone in two months - going down from 14 to 11 stone. But she soon found the outfits she was asked to wear in front of the camera were 'hanging off' her new slimline frame.

Harley Renshaw, five, from Manchester, is overjoyed to find out he is free of cancer, after battling an aggressive and rare neuroblastoma for a year. The tumour in his kidney had spread to his neck, lungs and bones and he underwent months of chemotherapy and radiotherapy. Doctors at the hospital where he received treatment were shocked when he asked to decorate the protective mask that keeps him still during radiotherapy. He turned it into a Ninja Turtles mask to help himself feel strong (he is pictured, right, wearing the mask). Now, although he will have check-ups in the upcoming years, he is free of cancer (he is pictured left and inset). His father, Oliver Renshaw, says he hopes Harley can soon go back to school full time. He said: 'We're just really excited and looking forward to the future.'

Dr Zoe Waller, 31, who works as a pharmacy lecturer at the University of East Anglia, Norwich, has dermatographia, where a raised, itchy rash appears on the skin at the slightest pressure. She can draw designs on her own skin, and is currently teaching her pharmacy students new drugs and molecules using her skin designs, which she uploads to social media. They have become so popular across the university that people are now making requests for what she should draw next. She was diagnosed with the condition two years ago, after seeing a picture of an artist who drew designs all over her own body. She says the condition doesn't hurt at all, and in fact describes it as 'pretty cool'.

Leza Davies, 33, from Telford, Shropshire, had a boob job in April 2007 as breast feeding had left her chest saggy. The procedure boosted her confidence and she settled down to life as a new mother. But in April 2012 she knocked her right breast on a door frame and found a pea-sized lump. Hospital tests revealed it was cancer, which was ununsual in such a young woman. She began six months of chemotherapy and radiotherapy but the cancer had spread to the surrounding tissue so after the treatment she had surgery to remove five lymph nodes filled with cancerous cells. Doctors said the treatment would leave her infertile, but remarkably, when she went for a mammagram to check she was in remission, she found out she was pregnant. Her third child, Araya-Maye (pictured inset) is now nine months old, and Mrs Davies says her boob job meant she discovered the lump and will now see her grow up. She said: 'If my breasts had stayed the same size I would never have knocked them. My implants saved my life.'

Emma Walker, 15. from Leicestershire, became consumed by an obsession to achieve the 'perfect body'. Such was the severity of her eating disorder, that the 15-year-old was admitted to hospital twice and faced rigorous counselling sessions after her weight plummeted to just five stone, left. Today, Emma, who is supported by her mother Kim (inset), said she wants to help other anorexia sufferers. By combating the compulsion to be skinny and rather focus on getting fit and building her muscle definition, she is now a healthier eight stone, right.
