Progress Educational Trust are hosting a series of events relating specifically to breast cancer. The variety of the talks cover genetics, gene testing, prediction, screening and risk.
Tonight’s free talk is being hosted at UCLH in North London and supported by Wellcome Trust. I was told about this event by a couple of people, one of whom had heard of it from the US and suggested I attend.
I was particularly pleased with the variety of speakers for tonight’s event. A spectrum of experiences and also of opinion.
Event Title: Risk Assessment: Breast Cancer, Prediction and Screening
Introductions from the organisers (Sarah Norcross – Director of Progress Educational Trust) and the Chair (Dr Ann Robinson – North London GP and Health columnist for the Guardian)
Wendy Watson (Founder and Director of the National Hereditary Breast Cancer Helpline)
Paul Serhal (Founder and medical Director of the Centre for Reproductive and Genetic Health)
Professor Stephen Duffy (Professor of Cancer Screening at Queen Mary University of London’s Centre for Cancer Prevention, and Director of the Policy Research Unit in Cancer Awareness, Screening and Early Diagnosis)
Professor Klim McPherson (Professor of Public Health Epidemiology at the University of Oxford’s Nuffield Department of Obstetrics and Gynaecology)
Each speaker only spoke for 10 minutes and this was then followed by an extensive question and answer session.
Wendy Watson spoke about her own journey. She was one of the first women in the UK to undergo a risk-reducing double mastectomy. Her own research led her to make and insist up on this surgical decision. She then sought to set up an advice line and raise awareness for others facing a similar decision. She has published her book “I’m still standing: My Fight Against Hereditary Breast Cancer”.
Wendy told us that 1 in 200 have genetic damage which may imply a higher risk of breast cancer. Wendy believes that more should be done and available on the NHS for women AND men to discover more about their genes and if any mutations have occurred. If you are concerned about a hereditary risk of breast cancer, her organisation, National Hereditary Breast Cancer Helpline offer support, advice and in some instances, funding for screening.
Our next speaker Paul Serhal. Paul spoke passionately about his field. He was responsible for the UK’s first baby born following pre-implantation genetic diagnosis for BRCA1 mutations.
Pre-implantation genetic diagnosis (PGD) is a technique that enables people with a specific inherited condition in their family to avoid passing it on to their children. It involves checking the genes of embryos created through IVF for this genetic condition. More information can be found at Human Fertilisation Embryology Authority.
Paul was passionate about the importance of his work and what it means to the people he assists. I was so pleased to hear also that they currently have no waiting time, have some funding arranged for suitable patients and can offer 3 cycles to each couple. I know of people who have the BRCA mutation and have considered NOT having children because of it. This work would assist many.
The third speaker was Professor Stephen Duffy. Prof Duffy was part of the original team who adapted the Swedish two-country trial of breast cancer screening on which the UK’s national breast screening programme was based. He remains an advocate of our screening programme and is often quoted at times when people say that the screening has led to over diagnosis of breast cancer in the UK. One such quote “In particular, it is good news that lives saved by screening outweigh over-diagnosed cases by a factor of two to one“.
He spoke about the difficulties of screening for women with dense breast tissue. This is often raised when discussing reducing the screening age as younger women tend to have denser breast tissue. Prof Duffy said that often there is less lead time to diagnose breast cancer due to the difficulties reading mammogram results of dense breast tissue.
I was delighted to see that he has also just been appointed as Senior Investigator by the National Institute for Health Research
Our final speaker was Klim McPherson. Klim focusses his research on epidemiological methods and women’s health. He spoke about the factors that contribute to breast cancer. To give you some idea, I found this quote from the BMJ “Klim McPherson is the man least likely to accept an invitation to lunch at McDonald’s”
His research has led him to look at and compare the US to the UK. He identified that the US certainly were far more radical with their surgery and treatments – however it wasn’t clear how much of this may be due to ‘insurance’ factors but felt not always necessary.
He was pleased to note that although breast cancer may be on the rise for being identified and diagnosed it was now much rarer to die FROM breast cancer.
So how can we avoid getting it?
- We are getting periods at a younger age and having children at an older age.
- He found that if you had your first period at the age of 11, you were 3 times more likely to get breast cancer than a girl who started their period of age 14.
- There is a higher risk of breast cancer in women who have taken the pill or HRT.
- 5 years of HRT doubles the risk of breast cancer.
- Obesity post-menopausal makes you at much higher risk of breast cancer.
There’s a 20% reduction in breast cancer when in the breast screening programme i.e. every three years. It is imperative that people attend their screening when invited.
There was then a long period for questions from the audience to the panel. As this was a free to attend event open to all, I was pleased to see a good variety of attendees and hence with the questions raised, I’ve stated who the questioner was.
Q1 Scientist – What’s the extent of genetics, epidemiology & screening connection?
KM – Yes they are connected. There is an Integrated Pathway (which is new) that is assisting with the integration of these three areas in determining healthcare.
Q2 Dr – If money was NOT a factor, what would a perfect screening programme look like for breast cancer?
SD – About right with the current screening programme i.e. 3 yearly mammograms. There is often talk of MRIs being better however patients don’t like MRIs and although they may be marginally more effective experience tells them that they produce more false positives so may lead to unnecessary surgery or treatment. Angular mammograms where using architectural distortion produces measurements of angular distribution i.e. slices of the breast may be more accurate but are complicated to read and produce.
Q3 Patient advocate – Spoke about the importance of trials, clinical and surgical. Asked what could be done to ensure more patient involvement and also of the recent DCIS trial.
Q4 Patient – What is offered to ladies under the age of 30 who have been tested positive for BRCA mutations by way of screening? Mammograms are not offered nor the option of going onto the normal breast screening programme.
SD – He reiterated that most screening is ‘pointless’ for people under the age of 30 due to the denseness of breast tissue.
Q5 Journalist from Pink Ribbon Magazine – To Paul asking more about the PGD programme and requesting information.
Q6(1) Clinical Geneticist – If we delayed puberty then this might/would reduce cancer… why can’t we?
There was much discussion about the ethics around this and although there was a consensus that it may reduce cancer, would it be ethical to do so?
Q6(2) – If each child was tested for BRCA at birth or perhaps a mutated bowel gene and found positive… could we delay their puberty knowing this may reduce their long term risk of cancer?
Again much the same discussion. Yes it may help but would it be ethical? What other implications may this have upon the person emotionally and psychologically?
Q7 Genetic counsellor – How many genetic counsellors are there in the UK and where are they? It was felt that many genetic scientists went on to become genetic counsellors and nurses in this field. However nobody was sure if there was a directory of genetic counsellors in the UK.
Q8 Patient – Why is breast cancer in younger women rising? What are the risk factors and how can people avoid them?
KM – He reiterated earlier periods and later pregnancy. He also discussed the increase in our use of plastic based products from an early life. Makeup, deodorant etc etc often contain oestrogen like products in the plastic and we’re putting this daily onto our skins from an early age.
There are two final events in the series. Sadly I’m unable to attend but please do go along ‘Risk Management: Breast Cancer, Business and Patents‘ on Thursday 5 June, and a concluding event on Thursday 3 July.
Thank you to the Wellcome Trust for supporting this series of events and UCLH for hosting these events by the Progress Educational Trust.
