Moles: Histological Testing

Caroline Johnson Excerpts

Thursday 30th October 2025 Westminster Hall

[Dr Caroline Johnson (Sleaford and North Hykeham) (Con)]

It is a pleasure to serve under your chairmanship, Ms Jardine. I congratulate the hon. Members for Isle of Wight West (Mr Quigley) and for South Norfolk (Ben Goldsborough) on securing this debate and on their very emotional speeches. I thank the hon. Member for South Norfolk for his bravery in talking about his own care. I commend Zoe’s family for their bravery and for their work to turn a family tragedy into something positive for other people, which is fantastic.

Melanoma is the deadliest form of skin cancer and, frighteningly, the fifth most common cancer in the United Kingdom: almost 20,000 people are diagnosed each year. It usually starts in skin or a mole that is over-exposed to ultraviolet radiation, and then it spreads to vital organs such as the lungs or the liver.

One of the challenges is that melanomas can be difficult to identify. I am a paediatrician, not a dermatologist, but I remember looking at pictures of melanomas and moles in medical school, and in lots of cases I struggled to see the difference that the lecturer was pointing out. They can be brown, red or pink; small or large; flat or raised. Unlike other cancers, which tend to progress as they grow larger, melanomas can be lethal even when they are very small, which means that there is no time to lose in having the diagnosis.

All suspicious moles removed by the NHS should be tested, but those judged benign or removed in cosmetic or beauty settings are not necessarily tested, as has been said. There is therefore the risk that, if that judgment was wrong, the cancer can go undetected and it can have tragic consequences. I want to ask the Minister what steps she is taking to strengthen the regulations in the aesthetics and beauty sector, in particular, and in the private medical sector. What will be done about lasering moles in a way that prevents identification of a melanocytic lesion?

We know that AI can help. There are now computer systems that look at moles in photographs and are reasonably reliable at discerning whether something is malignant. That can be done in conjunction with doctors and histology as an additional layer to ensure there are no mistakes. Will the Minister update the House on what she is doing with AI? One of the big shifts that the Government have talked about is digital, and that is one of the options available to them.

The Government have said that improving diagnosis is a key part of their national cancer plan. Will the Minister give us some highlights from the plan? We were expecting it to be published this year, but it is apparently now delayed until next year. There are rumours that that is to have a presentational effect on 4 February. Given that more than 1,000 people are diagnosed every day across the UK, I really hope that there are not presentational reasons for the delay. It would be helpful to know when she intends to publish the plan.

What assessment has the Minister made of the impact that the plan will have on the progress of speeding up cancer diagnosis for patients? How does she plan to expand access to genomic testing, which can also help to identify the most at-risk patients?

The Government have talked a lot about the shift to prevention, which is always better than cure. In about nine out of 10 cases, melanoma can be prevented. Avoiding over-exposure to the intensity of the sun, applying sunscreen and wearing suitable clothing can help to defend our bodies from the risk of developing melanoma. What assessment has the Minister made of the impact of the VAT charged on sun cream to the incidence of skin cancer? Sun cream can be quite expensive and young people may find that a barrier to applying it. With the Budget coming up just next month, the Minister is in a prime position to make that case.

It takes only one blistering sunburn to more than double someone’s chances of developing melanoma later in life. What steps is the Minister taking to ensure that young people are aware of the risks of sunburn? What discussions has she had with the Department for Education about making sure that young people are aware of the risk? Figures show that 65% of 18 to 32-year-olds report annual sunburn. Alarmingly, in May 2024, researchers predicted a record high of 20,800 skin cancer cases for the year. I worry that sunburn is increasingly regarded as one of those things—a sort of hallmark of a foreign holiday. What steps is the Minister taking to raise awareness of the link between sunburn and skin cancer?

It is not always sunny in the UK. That is why over one in four people, and 43% of 18 to 25-year-olds, use sunbeds to top up their tan. However, that comes with significant health risks. Researchers estimate that sunbeds cause 440 cases of melanoma and around 100 deaths every year in the UK alone. I was surprised to discover that only 62% of people know that sunbed use increases the risk of skin cancer. Worryingly, researchers found that 23% of 18 to 25-year-olds thought that using sunbeds instead of the sun would reduce their risk of skin cancer. What steps is the Minister taking to bust those myths? Will she consider using her women’s health strategy to raise awareness of these issues, which put mostly young women at risk?

Banning under-18s from using tanning beds was undoubtedly sensible, but insufficient enforcement mechanisms have been set up. Unfortunately, a 2025 survey by Melanoma Focus of 100 16 and 17-year-olds in the UK found that 34% were still using sunbeds despite the ban. Exposure to indoor tanning before 35 is associated with a 59% increase in the risk of developing skin cancer. Does the Minister have any plans to strengthen the enforcement of regulations that restrict the use of sunbeds by young people?

Frustratingly, not only do the regulations not stop vulnerable people using sunbeds, but they fail to restrict irradiation levels. A report suggested that over half of Tyneside sunbed salons exceeded the irradiation limits, putting users at even greater risk of cancer and melanoma. What steps will the Minister take to put safety first and ensure that sunbed irradiation levels are enforced?

The key measures against a cancer as deadly as melanoma, and our best defences against fatalities, are prevention, early testing, catching it early and good treatment. Given that such a high proportion of cases are preventable, I am interested to hear more about the Minister’s plans for further prevention and to know how the cancer plan will help. What are her thoughts on the plan for Zoe’s law to ensure that a histology test is always done so that no one slips through the net?
