Specialist maxillofacial surgeons Tim Martin and Sat Parmar prepare for a marathon operation on 53-year-old Teresa. Four weeks ago, Teresa was diagnosed with a fast-growing cancerous tumour in her face and she will die within weeks unless it is removed. The procedure involves radical surgery to the entire right-hand side of her face, and means she will lose both her upper jaw and right eye. It is an enormous undertaking for Teresa, and for Tim and Sat, too. Using 3D imaging, the team plan how to remove the tumour and, most importantly, how they will rebuild Teresa's face. Tim and Sat are all too aware that whilst removing the tumour will save her life, it will be devastating if she is left disfigured and unable to face the world. To give her the best possible outcome, they intend to fill the cavity left in Teresa's face with a section of bone and muscle removed from her hip, using a 3D-printed plastic guide that helps them cut out the correct shape bone.
Dr Kevin Fong explores a medical revolution that promises to help us live longer, healthier lives. Inspired by the boom in health-related apps and gadgets, it's all about novel ways we can monitor ourselves around the clock. How we exercise, how we sleep, even how we sit. Some doctors are now prescribing apps the way they once prescribed pills. Kevin meets the pioneers of this revolution. From the England Rugby 7s team, whose coach knows more about his players' health than a doctor would, to the most monitored man in the world who diagnosed a life threatening disease from his own data, without going to the doctor.

Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults. When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process. Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
