Is peanut butter linked to cancer?

Dry shampoo can be a lifesaver - a quick spray on busy mornings, after the gym, or when there’s just no time to wash your hair. But recent concerns about safety have left many people wondering: is it actually safe to use?

Is dry shampoo bad for your health?

Dry shampoo, in itself, isn’t known to be harmful. The worry started when small amounts of benzene - a chemical linked to cancer - were found in a few aerosol products. Benzene is classed as a known carcinogen, but the risk comes from high levels over long periods, often in industrial settings. That’s very different from occasional use at home.

In 2022, independent testing picked up very low levels of benzene in some batches of aerosol personal care products - including a few dry shampoos. As a precaution, those products were recalled. These recalls weren’t triggered by anyone developing cancer - they were a safety-first move. And it was only certain batches, not all dry shampoos.

What is the cancer risk from using dry shampoo?

The evidence so far suggests the cancer risk from using dry shampoo is extremely low for most people. Most of what we know about benzene and cancer comes from:

• Long-term, high-level exposure
• Daily contact in certain jobs
• Years of repeated exposure
  

That’s not the kind of contact people usually have with dry shampoo.

Is there a link between dry shampoo and cancer?

There’s no need to worry if you’ve been using dry shampoo - but here’s what you can do if you’re still concerned:

• Check your product to see if it was part of a recall
• Use sprays in a well-ventilated space to reduce any potential exposure
• Choose non-aerosol alternatives if you’d prefer to avoid sprays
  

If your product wasn’t recalled, there’s no evidence that it’s unsafe.

The current research does not show a clear link between dry shampoo use and cancer. The concerns relate specifically to trace benzene in certain spray products - and even then, the risk is thought to be very low. It’s always okay to ask questions about your health. And it’s also okay to want reassurance about everyday products.

On International Hot and Spicy Food Day, many of us will enjoy a meal that brings a familiar kind of heat. The sort that once felt overwhelming, but now barely registers. Over time, our tolerance builds, and what used to feel intense becomes manageable, sometimes even enjoyable. It’s a great example of how adaptable the human body is. But it also highlights something important about health, and about cancer in particular.

Why spicy food causes pain

The burning sensation from spicy food isn’t actually a flavour. It’s a pain response. Chilli peppers contain a compound called capsaicin, which activates pain receptors in the body that are usually triggered by heat or injury. These receptors send signals to the brain that something potentially harmful is happening, even though no real damage is being done. That’s why spicy food can feel so intense, especially at first.

Interestingly, research shows that with repeated exposure, the nervous system begins to respond differently. Studies using both behavioural testing and brain imaging have found that people who eat spicy food regularly often report lower everyday pain sensitivity, and show reduced neural responses to certain pain stimuli. In simple terms, the signal is still there, but the brain reacts less strongly to it.

This process is known as desensitisation. The body doesn’t stop detecting the stimulus, it just learns to live with it. Over time, spicy food feels less painful not because the heat has gone away, but because the nervous system has adapted. Some studies even show that people who enjoy spicy food begin to experience the sensation as more pleasant than unpleasant, highlighting just how much perception can change with familiarity and expectation - and this ability to adapt isn’t limited to food. People can also get used to physical symptoms.

A mild but persistent ache. A change in bowel habits. Ongoing fatigue. A feeling of being “off” that never quite settles. At first, these changes stand out. Over time, they become familiar, and familiarity has a way of quietening concern. Research into pain perception shows that how we experience sensations is shaped not just by what’s happening in the body, but by context, emotion and repetition. That means two people can experience the same symptom very differently, and it also means that symptoms which become part of everyday life can be easier to ignore, even when they’re still important.

Understanding persistent symptoms

Pain and discomfort aren’t just annoyances. They’re signals.

In cancer care, pain is one of the most commonly reported symptoms and remains an active area of research, both because of how often it brings people to medical attention and because of its impact on quality of life. Scientists are increasingly studying how the nervous system detects and communicates changes in the body, including those caused by cancer itself or by its treatments.

Many cancers are more treatable when they’re diagnosed earlier. But when someone becomes used to a symptom, they may delay mentioning it, sometimes without realising they’re doing so. The signal hasn’t disappeared, it’s just become easier to live with.

Recognising symptoms early

Early cancer detection doesn’t start with scans or tests. It starts much earlier, with noticing when something isn’t right for you. Noticing when a change doesn’t settle, when a symptom keeps coming back, or when “this is probably nothing” starts to feel like a familiar thought. Talking to a healthcare professional sooner rather than later can lead to reassurance, further investigation, or earlier diagnosis - all of which can make a real difference. Even when it turns out to be nothing serious, that conversation can provide clarity and peace of mind

So, on this International Hot and Spicy Food Day, we are asking you to remember that just like getting used to your favourite spicy food, it’s human to adapt, and it's normal to tolerate discomfort. But when it comes to health, especially when it comes to cancer, getting used to a symptom isn’t the same as it being normal. If something has changed, it’s worth noticing, and it’s worth discussing with a healthcare professional.

We’re proud to share that C the Signs’ partnership with NHS Suffolk & North East Essex Integrated Care Board (ICB) has been shortlisted for Best Technology Partnership with the NHS at the 2026 HSJ Partnership Awards.

The shortlisted entry recognises a collaborative programme across primary care that has helped clinicians identify patients at risk of cancer earlier - improving detection rates while delivering clear value for the health system.

Delivering meaningful impact at system level

Working closely with Suffolk & North East Essex ICB, the programme focused on supporting primary care teams to spot risk earlier, reduce unwarranted variation, and improve referral quality across the system. The results demonstrate what’s possible when technology is implemented thoughtfully and led by clinical need:

• An 800% return on investment, reflecting strong value for the wider health system
• A 12% increase in cancer detection rates, supporting earlier diagnosis and improved patient outcomes
  

Behind each of these figures are patients whose cancers were identified sooner, when there are more options and clearer next steps.

‍Dr Peter Holloway, GP Partner at Mendlesham Practice, Cancer Lead for Suffolk and North East Essex ICB, Chair of the Primary Care Group for the East of England Cancer Alliance, and Cancer Research UK GP for the East of England said:

“We must strengthen primary care’s ability to recognise early symptoms of cancer and ensure timely investigation and referral. C the Signs – a clinical decision support system integrated seamlessly within GP IT systems – helps deliver on these objectives.

What does “best technology” mean to us?

For us, being recognised as a leading technology partnership isn’t about software alone. It’s about patient safety, real patient impact, and clinical excellence. It means technology that clinicians can trust, that supports careful decision-making, and that fits naturally into everyday care. Above all, it means helping identify patients at risk of cancer earlier - when there is more time, more clarity, and more opportunity to act.

The HSJ shortlisting recognises not only what was achieved, but how it was delivered. The partnership focused on embedding the C the Signs platform into everyday clinical workflows - supporting clinicians with real-time decision support and using population-level insight to guide system-wide improvement. By working closely with GP practices, cancer alliances and ICB leadership, the programme aligned digital innovation with frontline realities. That collaboration helped ensure strong adoption, clinical confidence, and long-term sustainability.

It’s a reminder that earlier diagnosis doesn’t come from technology alone - it comes from people, partnership, and trust.

Recognised by healthcare leaders

The HSJ Partnership Awards are widely regarded as one of the most respected benchmarks for collaboration between the NHS and its partners. Following a rigorous judging process, C the Signs and NHS Suffolk & North East Essex ICB were named among more than 160 finalists, selected from over 240 entries across the 2026 awards programme. Entries were reviewed by a panel of senior healthcare leaders, including NHS trust chief executives, clinical leaders and public health directors.

Luke Wyatt, PatnershipsDirector at C the Signs said:

“This shortlisting reflects what’s possible when the NHS and technology partners work together with a shared purpose. We’re incredibly proud of the partnership with NHS Suffolk & North East Essex ICB, and of the clinicians and teams whose commitment has driven these outcomes for patients.”

The winners will be announced at the HSJ Partnership Awards ceremony on 19 March 2026, held at Evolution London.

Being named a finalist is an important milestone - not just for C the Signs, but for the NHS teams who continue to show what can be achieved through evidence-led, collaborative approaches to earlier cancer diagnosis.

When cancer is found earlier, people are given something invaluable back: more time, more clarity, and more chance to plan their future.

Northamptonshire ICB, in partnership with East Midlands Cancer Alliance, have taken an important step towards earlier, more equitable cancer diagnosis - bringing C the Signs to every GP practice across the county.

This move follows strong demand from clinicians across Primary Care, many of whom asked for extra support in spotting cancer earlier and gaining clearer guidance when symptoms are hard to interpret. It reflects a shared commitment across the county: to give patients the best chance of being seen, understood, and referred in time.

Listening to clinicians, supporting patients

In busy GP practices, symptoms can be subtle, overlap with everyday conditions, or appear gradually over time. It’s easy for patients - and even experienced clinicians - to feel uncertain.

Northamptonshire ICB heard repeated calls for a system that could bring together complex information, reduce the burden of manual processes, and offer an extra layer of safety and clarity. With C the Signs now in place, clinicians have consistent, integrated support to help identify risk earlier across more than 100 cancer types.

Championing early diagnosis across the county

This rollout has been shaped by local clinical leaders who have long advocated for reducing variation in early cancer detection.

Dr Azhar Ali, Clinical Lead for Cancer at Northamptonshire ICB, shared his hope for what this will mean for patients and families across the region:

“With C the Signs in place, we can reduce any variation of early cancer detection irrespective of where they live within Northamptonshire. As an ICB, we are committed to a stage shift to more cancers being detected at stages 1 & 2 and therefore reaching better outcomes for patients.”

Dr Catherine Massey, Clinical Director at Grand Union PCN, highlighted how additional safety and clarity can support busy primary care teams:

“We’ve had some significant events in the past where two-week-waits were missed. C the Signs is a safe system that stops these near misses, and makes decision-making as a GP easier and safer.”

Their leadership has helped shape an implementation that meets the needs of both clinicians and patients.

A shared commitment to earlier diagnosis

The Northamptonshire rollout marks a significant moment for the region and for the national movement towards earlier cancer detection.

It shows what is possible when clinicians speak up for what they need, and when systems listen. It shows the value of giving every patient - in every community - the same chance of being seen early, and it shows the power of combining clinical expertise with technology designed to support, not replace, the human judgement at the heart of Primary Care.

A new study presented at the ASCO Care Quality Symposium 2025 and published in the Journal of Clinical Oncology (JCO Oncology Practice) has shown that C the Signs, an artificial intelligence (AI) platform supporting earlier cancer diagnosis, has delivered an 808% return on investment (ROI) for the NHS.

Commissioned by Health Innovation East, the independent evaluation found that implementation of C the Signs across Suffolk and North East Essex Integrated Care Board (ICB) was associated with 272 patients being diagnosed earlier and £1.5 million in annual cost savings - demonstrating how AI can help improve patient outcomes and optimise NHS resources.

By helping GPs identify patients at risk of cancer sooner and reduce unnecessary urgent suspected cancer (USC) referrals, the platform has also eased system pressures and released valuable clinical capacity across the region.

“This study provides clear evidence that AI can make a measurable impact on cancer care,” saidDr Miles Payling, Chief Scientific Officer at C the Signs. He went on to say:

"An 800% return on investment means we’re improving early diagnosis and helping the NHS use its resources more efficiently. It’s a practical example of innovation making care better for both patients and clinicians.”

The study builds on earlier research, also published in JCO Oncology Practice and presented at ASCO, which found that GP practices using C the Signs achieved a 12% increase in cancer detection rates - from 58.7% to 66.0% - without increasing referral activity.

Together, these studies show that C the Signs helps detect more cancers at an earlier stage while maintaining stable referral volumes - supporting NHS priorities around early diagnosis, productivity, and elective recovery.

“Early diagnosis gives patients the best chance of successful treatment,” said Dr Seema Dadhania, Clinical Oncologist at Imperial College London and author of the study. Dr Dadhania further stated:

“C the Signs is helping primary care clinicians identify those subtle cancer presentations that can otherwise be missed - improving detection while reducing unnecessary referrals. It’s a model for sustainable early diagnosis.”

Scaling Across the East of England

Following the success in Suffolk and North East Essex, Health Innovation East has supported the expansion of C the Signs across Norfolk and Waveney ICB, with further rollouts planned across the East of England.

Piers Ricketts, Chief Executive at Health Innovation East said:‍

“This work is a strong example of technology delivering measurable benefit. C the Signs has shown that AI can help clinicians find cancer earlier.

He continued: "This is of obvious benefits to patients whilst also easing the pressure on NHS services, in particular on primary care. The results from Suffolk and North East Essex are a real success story for innovation in the NHS and show how the service can progress towards its goal of increasing early detection rates from 50% to 75% by 2028.”

‍Dr Peter Holloway, GP Partner at Mendlesham Practice, Cancer Lead for Suffolk and North East Essex ICB, Chair of the Primary Care Group for the East of England Cancer Alliance, and Cancer Research UK GP for the East of England said:

“The NHS has set an ambitious target to achieve 75 percent early stage cancer diagnoses by 2028. To reach this, we must strengthen primary care’s ability to recognise early symptoms of cancer and ensure timely investigation and referral. C the Signs – a clinical decision support system integrated seamlessly within GP IT systems – helps deliver on these objectives.

Shedding further light on the impact, Dr Holloway said: "Research has shown a 12 percent increase in cancer detection rates in Ipswich and East Suffolk following its implementation. Moreover, it demonstrates a strong return on investment: by ensuring patients are quickly directed to the right pathway, the system effectively pays for itself and reinforces the value of a digital first approach.”

Actor James Pickens Jr., known to millions for his role as Dr Richard Webber on Grey’s Anatomy, has shared his personal experience with prostate cancer - a decision he hopes will encourage more men, especially Black men, to understand their risk and speak to a health professional sooner.

Pickens, now 73, was diagnosed after his annual physical in 2024. For him, the news was not entirely unexpected. Prostate cancer has affected many men in his family across generations. That family history meant he was diligent about monitoring his health - something that ultimately made all the difference.

“My urologist said it worked in my favour,” he shared.

“Because I was so consistent with my testing, they were able to catch it early.”

During his check-up, elevated PSA levels led to a referral to a urologist. A biopsy confirmed a tumour, and a PET scan showed it hadn’t spread. Given his early diagnosis, Pickens was able to choose between radiation or surgery. He opted for a robotic prostatectomy, supported by a team who kept a close eye on a rare cancer variant found during testing.

“They told me they hadn’t seen one detected as early as mine,” he said - a powerful reminder of what’s possible when cancer is identified in time.

Pickens has spoken openly about the stigma that often surrounds men’s health, especially conversations about prostate cancer. Many men delay seeking help, feel uncertain about what’s normal, or worry about “making a fuss”. These barriers are even more pronounced for Black men, who face a higher risk due to genetic and structural factors.

“One in eight men will be diagnosed with prostate cancer,” he said in a recent public message. “For Black men, the risk is even higher. His story reinforces a truth we hear across healthcare: the earlier prostate cancer is detected, the more options men have - and the better their outcomes can be.

"Early detection is key, and sometimes there are no noticeable symptoms.”

How do you know if you have prostate cancer?

Prostate cancer can be difficult to recognise in its early stages - not because people aren’t paying attention, but because the body often gives very few clues at the beginning. That’s why understanding your own baseline, your personal risk, and what feels normal for you is so important.

There isn’t one single sign to look out for. Instead, there are moments worth pausing on - small changes, shifts in how your body behaves, or a sense that something simply feels different.

You don’t need to be certain something is wrong before speaking to a doctor. You just need to notice a change.

For many men, that might look like:

• A change in the way you urinate - starting, stopping, or feeling different
• Going more often, especially at night
• A stream that feels weaker or slower than usual
• A lingering sense that your bladder hasn’t fully emptied
• Or simply a feeling that something isn’t quite your normal

These changes don’t automatically mean prostate cancer. They’re far more often caused by benign prostate enlargement - a common part of ageing. But they are still worth a conversation, because the earlier any prostate issue is understood, the more options you have.

Your risk also changes over time. Growing older, having Black heritage, or having a family history of prostate, breast or ovarian cancer can increase the chance of developing prostate cancer - which is why some people choose to check in sooner.

A doctor may talk to you about a PSA blood test - a simple blood test that measures the level of prostate-specific antigen - a protein made by the prostate. It isn’t a diagnosis, and it doesn’t give all the answers - but it can offer a helpful starting point if you want to understand your risk more clearly.

What matters most is listening to your body. You know when something feels different. And you deserve to be taken seriously, to ask questions freely, and to have the right support at the right time.
