Lobular Breast Cancer: Moon Shot Project

Debate between Scott Arthur and Sam Rushworth

Thursday 9th July 2026 Westminster Hall

[Dr Scott Arthur (Edinburgh South West) (Lab)]

It is a pleasure to serve under you in the Chair, Mrs Hobhouse. Like others, I thank the hon. Member for Horsham (John Milne) for introducing the debate and for how he did it.

I want to make a prediction. I think the remaining speakers are going to say that they support this campaign and that they want to see a difference, and they will acknowledge the gap that needs to be filled. Our challenge is making that pledge and those words real. I have been in debates like this before—we all agree that something has to be done, yet we come back and speak about it again and again. Perhaps, if we all carry this campaign forward, this is the time to actually make it happen.

[Sam Rushworth]

My hon. Friend just made an excellent point. We know the research questions that need to be answered. Does he agree that it should not be beyond UKRI to put out a specific call asking people, through a competitive peer review process, to answer those questions?

[Dr Arthur]

Exactly. In a former life, I was an academic. UKRI does at times engage with academics to fine-tune such questions. UKRI provides funding to universities, if needed, to bring the very best people to the UK either temporarily or on longer-term contracts to help to make a difference in the UK. Those things are perhaps all part of the solution. My hon. Friend is absolutely right.

I am grateful for the opportunity to support this vital debate. It shines much-needed light on a disease that is still under-resourced, as has been said, and it honours the legacy of a woman who dedicated her final years to fighting it: the late Susan Michaelis. I was not fortunate enough to meet her but, as a result of the excellent introduction of the hon. Member for Horsham, I feel I know a little bit about her and her character. I am grateful for that introduction.

Lobular breast cancer, despite being the second most common form of breast cancer, has historically received a mere 1% of breast cancer research funding. Susan refused to accept that disparity and the Lobular Moon Shot Project is her legacy—but it has to be more than a project. Hopefully, progress will be her real legacy. The project demands better treatment for every woman who receives a lobular breast cancer diagnosis. That is why all of us are in the Chamber for this debate.

I recently received an incredibly powerful letter from a leading oncologist, Dr Michie. She is based in Edinburgh, treats patients in Scotland and works closely with the community of those with lobular breast cancer. She expressed deep professional frustration on behalf of her patients, explicitly stating that lobular breast cancer has been neglected for too long. People who meet patients day in, day out and week in, week out still have a real frustration about the lack of progress. Dr Michie’s letter also highlighted the fact that lobular breast cancer is different from the more common ductal types of breast cancer, with an entirely unique tumour biology, different responses to drug treatments, and distinct and highly challenging patterns of spread.

The different response to drug treatments is really important because, in the absence of proper treatments, women are often faced with a drug that was not actually designed for the condition that they have. Yet clinical trials rarely even present separate response data for lobular cases: today a grand total of zero lobular-specific clinical trials are actively recruiting patients in the UK. That should shame us, based on what we have discussed already in this debate, and on the scale and breadth of the campaign that has been run.

Additionally, the incidence of lobular breast cancer is rising rapidly, climbing by nearly 3% annually. Because it does not form the typical lump, it is notoriously difficult to detect using classical imaging. That is 3% annual growth in diagnoses of this condition—I know that, as a Government, we are really keen on growth but not that kind. To fix it, we need to improve our pre-clinical understanding of how and why the disease spreads. I believe that the work package plan of the Lobular Moon Shot Project is precisely the kind of ambitious and collaborative plan that can help us to improve patient outcomes across the board. If people do not believe that, let us have a conversation about how it can be improved.

Road Safety Powers: Parish and Town Councils

Debate between Scott Arthur and Sam Rushworth

Monday 30th June 2025 Commons Chamber

[Sam Rushworth]

I welcome that intervention. Parish councillors do sterling work, and all who volunteer and give their time for speed watch schemes are making life that bit better for people in their communities. Nonetheless, people get frustrated when often that data is not taken where they want it to be taken.

In the village of Hamsterley in my constituency, the traffic through to Hamsterley forest on the weekend is often a cause of concern. Villagers there have asked if the village could be made a 20 mph zone, which sounds to me like a reasonable request. In fact, they have often asked me, “Why can’t we be more like Wales?” Welsh villages are allowed to be 20 mph zones, and my constituents get frustrated that they do not have that option.

[Dr Scott Arthur (Edinburgh South West) (Lab)]

On that point, why should they be like Wales, when they could be like Edinburgh? Will my hon. Friend join me in paying tribute to former councillor Lesley Hinds? One could never meet a more humble Labour councillor, but back in 2016, she rolled out Edinburgh’s city-wide 20 mile per hour zone. In 2022, independent peer-reviewed research showed that slight injuries had reduced by 37%, serious injuries had reduced by 33% and fatalities had reduced by 23%. Through the leadership of one person, lives had been saved. Does he agree that we should be using such measures right across the country?

[Sam Rushworth]

That important data gives force to my argument. We are not talking not about killing people’s joy but enhancing joy in their lives so that they feel safe to walk in the roads in their villages.
