How reconstructing the past hepatitis B epidemic can help prevent liver cancer in the future

Nora Schmit was shortlisted for the MRC Max Perutz Science Writing Award 2019 for the following article on her PhD research on predicting the impact of treatment for hepatitis B infection on preventing liver cancer in The Gambia.

What’s the first thing that comes to your mind when you think of cancer prevention? Maybe you’re thinking of not smoking or maintaining a healthy weight – great strategies to reduce your chance of getting cancer.

But did you know that the hepatitis B vaccine, introduced in the 1980s, has long protected children in many parts of the world from developing one of the most common and deadliest cancers later in life?

Although most people have no symptoms when they first become infected, the hepatitis B virus is the leading cause of liver cancer worldwide. Large-scale efforts to tackle the virus using vaccination have been hugely successful in preventing infections in children. Despite this remarkable achievement, hepatitis B infections are still very common and nearly a million people die from its consequences every year. With around 6% of all people living in Africa currently infected, the death toll there is expected to rise even further.

But while a liver cancer diagnosis is nearly always fatal, treating the infection is possible with the same drugs that work against HIV. So why do so few people receive these drugs, when over half of all liver cancer deaths globally are preventable? (more…)

Breastfeeding and Breast Cancer: Exploring the potential link

PhD Sophia D'AlessandroOctober is Breast Cancer Awareness Month. This is a crucial time to raise awareness about screening, treatment, and prevention of breast cancer. PhD student, Sophia D’Alessandro from the Department of Surgery and Cancer examines her research looking at the link between breastfeeding and the reduced risk of breast cancer in our latest blog.

Breast cancer is one of the most prevalent cancers in the world, alongside prostate, lung and colorectal cancer. It is estimated that there are more than 150 new cases diagnosed every day. But why does breast cancer occur? We know cancer is a multifactorial disease caused by a variety of different factors, which can include mutations in key cancer-causing genes, and lifestyle-related risk factors such as age, being overweight, smoking, family history of breast cancer and hormone therapies. However, there are also factors that can reduce a person’s risk of breast cancer risk, such as breastfeeding. 

Current research suggests that the risk of developing breast cancer decreases by 4% for every 12 months of breastfeeding. But it’s not yet clear why. The primary function of the human breast is to produce nutrient rich milk for babies. Therefore, the complex structure of the breast is designed for this function. It is comprised of fatty adipose tissue, surrounding lobules and ducts. The lobules produce milk, and the ducts transport it to the nipple, where it can be expelled and fed to a baby. In addition to this, the ducts of the breast are lined by a layer of specialised cells known as epithelial cells. It has been shown previously that breast milk may contain some of these breast epithelial cells, which are then digested in the babies’ stomach and cause them no harm. However, around 85% of breast cancer cases arise from the epithelium, so it is thought that the loss of mutated breast epithelial cells through breastfeeding may play a role in reducing breast cancer risk.

The iKnife – the cutting-edge of cancer diagnosis?

The iKnife analysing a liver tissue sample

For all the advancements medicine has seen in recent decades, there remains a major public health challenge: cancer. However, a new surgical tool called the iKnife has shown significant promise in improving the diagnosis of endometrial (womb) cancer. Professor Sadaf Ghaem-Maghami discusses how this new tool could transform the clinical care of thousands of patients.

Endometrial (womb) cancer is the most common gynaecological cancer in the UK, and the fourth most common cancer in women. It affects 9,300 women and people with gynae organs every year in the UK alone. It generally occurs in postmenopausal women, but up to 25% of cases are diagnosed in the pre-menopause. Its main symptom is one of abnormal bleeding. These women are usually referred to the two-week wait clinics for diagnosis or exclusion of cancer.

Blood Cancer Awareness Month: all roads lead to EVI1

PhD student Philippa May reflects on being a scientist in the field blood cancer, from working in a leukaemia diagnostic laboratory to a research laboratory. 

For the last 10 years I have been a clinical scientist in genetics working across various London NHS Trusts. Whilst I loved diagnostics, last year I left my job to complete my PhD. I worked in a part of life sciences called cytogenetics. This meant when a patient was diagnosed with blood cancer, I would analyse their chromosomes – the structures into which DNA is organised – from their blood or bone marrow to look for specific abnormalities. For some patients, this can lead to a definitive diagnosis. For others a refined prognosis, and in some, it’s simply a way of monitoring how well the patient’s leukaemia is responding to their treatment. (more…)

Eliminating hepatitis B: Bridging research, policy, and practice

Clinical Associate Professor, Shevanthi Nayagam

On World Hepatitis Day, Clinical Associate Professor, Dr Shevanthi Nayagam, working across the School of Public Health and Department of Metabolism, Digestion, and Reproduction, shares how her research is helping shape global and national strategies to eliminate hepatitis B (HBV). From modelling vaccine impact to supporting birth dose policies in Africa, she highlights the power of evidence, collaboration, and local action in tackling this silent epidemic. 

Hepatitis B is a virus that attacks the liver and, over time, can cause serious complications such as cirrhosis and liver cancer. What makes it particularly dangerous is that many people don’t realise that they are infected – it can silently damage the liver for years without causing symptoms.  

One of the things that motivated me to start research in hepatitis B over a decade ago, was just how little attention this virus received, despite affecting 254 million people. In 2022 it was estimated to have caused 1.1 million deaths. I’ve seen how hepatitis B continues to affect the lives of those living with the infection and their families – particularly in low- and middle-income countries where prevention, diagnosis and treatment are often out of reach.  

My translational research sits at the intersection of clinical epidemiology, modelling, and health economics – all aimed at an overarching goal: supporting countries to eliminate viral hepatitis through evidence-based decision making. 

A big part of my work involves connecting the global with the local. This dual approach helps ensure that international recommendations are grounded in real-world data . Of course, this kind of work isn’t done in isolation. Everything we do depends on strong collaboration with a wide range of partners – including clinicians, scientists, ministries of health, policy makers and funding agencies.

On the national day of France—known as ‘Bastille Day’ in English—we hear from Prof Maud Lemoine, Professor and Honorary Consultant in Hepatology at Imperial’s Department of Metabolism, Digestion and Reproduction. She completed her medical degree and PhD in Paris, France, before working in The Gambia, and then the UK  

What brought you to London, and Imperial?

Initially I came a bit by chance. I was working in a teaching hospital in Paris as a full-time clinical consultant, having completed a PhD in physiopathology of non-alcoholic fatty liver disease. I wanted to work abroad and was very interested in working on viral hepatitis and liver cancer in sub-Saharan Africa. I wanted to work in a non-French speaking environment and meet other cultures. In 2011, by chance, I met Prof Mark Thursz who gave me the opportunity to join his team. I spent about 2 years and a half in The Gambia where I implemented a very ambitious research programme on liver diseases in West Africa. Then, in 2014, I moved to London. I hadn’t planned to move to London, but then I discovered a different culture—where I was given so many more opportunities than I’d have in the French system. I was extremely motivated but more importantly I felt really supported by Imperial and my department to develop my ambitions and create my own research group. I do still miss the French system from which I have learnt a lot.

I was initially going to spend a year or two as a lecturer at Imperial, but then I secured more funding to expand my research activities and really enjoyed the work environment and its management based on trust and creativity—especially as it’s much more diverse here. There are so many different nationalities represented in our department, it’s really nice.

Hope for a hepatitis B cure: the cunning virus that is outsmarting scientists

For World Hepatitis Day, Dr Ana Ortega-Prieto explains why she switched her research focus from hepatitis C to hepatitis B – a virus that continues its global spread despite an available vaccine. 

When I first started to work on hepatitis C virus (HCV) for my PhD, the general conviction was that it was a dangerous pathogen with very unsuccessful treatments. In the past years, this has completely changed; patients used to endure one year of treatment with severe side effects, but can now expect just three months of treatment, which is generally well tolerated. The truly impressive part here is that treatment success went up from below 50% to well over 90%. This has triggered the World Health Organisation (WHO) to aim for the eradication of all viral hepatitis by 2030 – a very ambitious goal. (more…)

How machine learning will transform the way we look at medical images

Machine learning

Dr Tim Hoogenboom, a Research Sonographer, looks at the promise and perils of machine learning in medical imaging.

Medical imaging is key in today’s delivery of modern healthcare, with an immense 41 million imaging tests taking place in England in every year. Thousands upon thousands of patients safely undergo imaging procedures such as X-ray, ultrasound, and MRI every day, and the product of these tests – the images – play an essential role in informing the decisions of medical professionals and patients in nearly every area of disease.

Imperial College medical student receives The Diana Award

Haroop BolaFinal year medical student, Harroop Bola, and Founding Chair of the British Indian Medical Association, which received the Diana Award last year, shares how the association fosters mentorship, education, and leadership for medical professionals from Widening Participation backgrounds. He highlights BIMA’s impactful initiatives, from academic workshops to community support, inspiring the next generation of changemakers in the NHS and global healthcare. 

I am delighted to share that my work with the British Indian Medical Association has been honoured with the Diana Award 2024- the highest accolade a young person can achieve for social action or humanitarian efforts. Established in memory of Diana, Princess of Wales, the award is given out by the charity of the same name and has the support of both her sons, HRH The Prince of Wales and Prince Harry, The Duke of Sussex. 

Joining Imperial College London’s School of Medicine as a first-generation university student without established connections in medicine was an intimidating journey. While access to medical school has improved through widening participation initiatives, the systemic challenges remain; opportunities within medicine often favour those with access to high-quality mentorship. With approximately one-third of medical students coming from medical families and competition for training posts increasing annually, mentorship has become an invaluable asset. For individuals like me, navigating the complexities of a medical career and building a competitive portfolio without prior insight into the profession can feel overwhelming.

During the height of the COVID-19 pandemic, as I transitioned from my first to second year of medical school, I joined forces with Dr Amar Rai and Virensinh Rathod to establish the British Indian Medical Association (BIMA). Our vision was simple yet powerful: to foster a sense of community within the medical field and leverage collective support to address gaps in education, mentorship, and cultural identity.

Guide to Sober October: what’s in it for you?

David Nutt

This month, people worldwide will take on the 31-day ‘Sober October’ challenge, a movement that began in the UK to raise funds for Macmillan Cancer Support, benefiting those with cancer. Even if you’re not officially participating, Sober October offers a chance to reset your body and rethink your relationship with alcohol. In our latest blog, Professor David Nutt from the Department of Brain Sciences shares expert tips on how to make the most of this healthy, alcohol-free month.

Sober October is here, and it’s the perfect opportunity to hit reset on your relationship with alcohol – whether you’re looking to completely abstain or simply cut down. Much like Dry January or Dry July, this month-long challenge is about taking a break from alcohol and reassessing its place in your life.

With alcohol consumption on the decline among Gen Z and Millennials, it’s clear that more and more people are recognising the benefits of taking a break from booze and now is the perfect time to jump on board.

Sober October is a global movement encouraging people to stop drinking for the month of October. For many, it’s a time to take a break and rest after summer’s social gatherings and prepare for the end of year holiday season with a clearer mind. It’s not just about abstinence; it’s also about fostering better health, improving mental clarity, and building positive habits for the future.

Progress not perfection

Stopping alcohol intake for a whole month can have major health benefits.  People who participated in previous abstinence challenges like Dry January have reported improved sleep (56%), weight loss (38%), and better mental health. Even those who didn’t make it through the full month still saw long-term reductions in alcohol intake and enhanced well-being, showing that it’s about progress, not perfection.  There are also likely to be measurable physiological improvements such as lowering your blood pressure if you are hypertensive, losing weight (as alcohol has more calories than most people imagine) and putting more money in your pocket – perfect for upcoming holiday shopping.
