Overview

We often underestimate the importance of the lips as a symbol of expression, as they enable us to connect with other people through speaking, laughing, and smiling. Sadly, lip cancer can develop on the vermilion border (the pink transitional area from the skin), the internal mucosa (lining inside the lips), the external skin above the lips, and the corners of the mouth.¹ Most commonly, a type of squamous cell carcinoma, it typically affects the lower lip visibly and is strongly linked to prolonged sun exposure, affecting certain individuals more than others.² Some risk factors are smoking, chewing tobacco, weakened immune systems from organ transplants, and a history of strain 16 and 18 human papillomavirus (HPV) infections.¹

When someone is diagnosed with lip cancer, the journey is more than just removing the tumour.³ Surviving cancer is one thing, but living well after cancer is just as important. The constant need for check-ups and the challenge of dealing with side effects that linger after recovery can be complex.⁴ With the fear of the disease coming back or even developing a related head and neck cancer, this marks the beginning of a new kind of anxiety: the ‘what ifs’: what if something is not right and I do not know about it? What if the cancer returns? In this next chapter for lip cancer survivors, follow-up care plays a crucial role in terms of clinical monitoring and catching signs of recurrence early, whilst also helping individuals rebuild confidence to manage physical changes and feel supported as they move forward.⁶ 

Importance of follow-up care

Most lip cancer recurrences happen within the first one to three years after treatment, making check-ups during this period the most critical.⁴ Early detection means doctors can make decisions to act quickly before the cancer becomes difficult to treat.⁶ Surveillance is about watching out for cancer, and also a chance to track and manage the long-term effects of treatment.⁴ It also helps to manage any ongoing physical effects of treatment so that even when the cancer is gone, survivors may still deal with dry mouth, scarring, speech difficulties, or numbness, particularly if radiotherapy was involved.⁷ These patients may be referred to specialists like speech therapists, dentists, and even dermatologists as part of a wider care team.⁷ 

Lip cancer can be an isolating, anxiety-riveting experience, especially if their appearance or ability to speak has changed.⁸ This is where follow-up appointments excel in ways to provide patients with a sense of continuity and a safe space to talk about how they are coping mentally.⁵ These moments matter because it is not a one-size-fits-all process; each patient has a unique cancer journey, and their needs will vary after treatment.⁴ The aim is to offer individual care that addresses both the medical and human experience of recovery to ensure no one feels like they are facing it all alone.⁸ 

Risk factors for recurrence

Even though many people go on to recover entirely from lip cancer, there is always a possibility that it can come back.⁵ What makes it tricky is that not everyone has the same level of predisposition, so understanding the risk factors for recurrence can help plan follow-up care and patient awareness.³ The strongest predictor for recurrence is how far the cancer had spread at the stage of diagnosis.⁶ If it were caught early, the chances of returning are usually lower, but if it had already spread to nearby tissues or lymph nodes, the risk becomes understandably higher.³ Similarly, the size and depth of tumour growth and incomplete removal of cancer cells during surgery are all warning signs that recurrence can happen.⁴ Men also face a 3.8 times higher risk of cancer recurrence compared to women, which indicates a discrepancy between gender groups.⁶ There are also lifestyle-related risks such as tobacco usage, drinking, and no protection from ongoing UV exposure, which make a person more vulnerable to developing lip cancer again.¹ Unfortunately, recurrence does not always happen at the same site, as some patients develop a ‘second primary cancer’.⁵ This is more likely in individuals who have a history of multiple risk factors with an underlying genetic susceptibility.⁶ 

Standard surveillance protocols

Once lip cancer treatment is complete, follow-up care becomes a regular part of life.³ Such reviews may feel routine, but they allow healthcare teams to monitor how the body is recovering and intervene early if new symptoms appear.⁴ When the risk of recurrence is highest during the first few years, follow-up visits are frequently scheduled about every 4 weeks for the first 6 months.⁴ Appointments may be spaced out every 2 to 3 months until the two-year mark, and then shift to annual check-ups once the patient is more stable.⁴ Of course, these timeframes may vary depending on the patient’s case, where the original cancer was and the type of treatment they received.³ It is also important to note that recurrence can present differently so knowing what to look out for is crucial: the same spot on the lip (local recurrence within 5 years), spread to lymph nodes in the neck (regional recurrence), or even spread to other parts of the body like the lungs (distant metastasis).⁴ Patients also face a risk of developing a new cancer elsewhere in the head, neck, or aerodigestive tract, so identifying these recurrence distinctions helps tailor the next steps in treatment.⁴ 

At each check-up, doctors carry out thorough physical examinations with observations focusing on the lips, oral cavity, and lymph nodes surrounding the head and neck area, which are common sites where the cancer may return or spread.³ Using a mirror and lights, the clinician will be gloved to feel the inside of the patient’s mouth (tongue, gums, cheeks, floor and roof of the mouth).³ If anything looks abnormal, a biopsy will be conducted by a pathologist to rule out recurrence.³ In some cases if symptoms are concerning or if the cancer becomes advanced, magnetic resonance imaging (MRI), computed tomography (CT), or positron emission tomography (PET) scans will be used to build a complete view of the affected tissues which can pick up even subtle changes that are not obvious from the surface.³ 

Patient education and self-monitoring

Hospital check-ups happen every few months, but the truth is, cancer does not work to a timetable. This makes educating patients on how to look after themselves between appointments just as important as anything that happens within the clinic.³ Education is not just one conversation; it is ongoing and tailored to the individual to feel informed as they adjust to life after lip cancer.⁶ Self-monitoring for unusual changes such as non-healing ulcers, discolouration, or a persistent wound around the lips can be indications of lip cancer recurrence.⁶ Knowing what to look out for, even if they seem minor, can be beneficial in seeking help from healthcare professionals.⁷ Alongside this, patients should also be given clear and non-judgmental advice about the benefits of quitting smoking, reducing alcohol intake, and protecting their lips from sun damage.³ Two simple lifestyle choices that go a long way to protect the lips and stay well are to use SPF lip balms and wear wide-brimmed hats.² 

Psychosocial and quality of life support

Psychosocial support and quality of life (QoL) must be considered an essential part of follow-up and not just an optional extra.⁸ The lips are central to basic motor functions such as speaking clearly, smiling, and eating comfortably, which affect someone’s QoL, as even small alterations can be frustrating after lip cancer.⁷ This is why involvement from speech and language therapists is vital for physical rehabilitation and to help people feel more at ease in their daily interactions.³ 

For some, the emotional aftershocks and body image issues of lip cancer do not end with treatment.⁸ Surgery or radiotherapy to the lips or the surrounding areas can leave visible scars or stiffness that alter how someone looks or moves their mouth, deeply affecting an individual’s self-esteem.² These changes may seem small to others, but the survivor may avoid social gatherings and struggle with personal relationships due to how others may perceive them.⁸ With their emotional pain just as real as the physical, the anxiousness of recurrence or even survivor’s guilt is quite common.⁸ Access to mental health support, such as psychological counselling or peer support groups for cancer survivors, to reassure them that their feelings are valid, can make a meaningful difference.⁷ Lastly, QoL also includes the little things: from the ability to eat their favourite foods to speaking without hesitation and feeling comfortable in their skin. So, however small they seem, helping survivors regain these everyday joys is a powerful part of their healing journey.⁷ 

Summary

Most lip cancer cases have generally positive outcomes, which provides relief to patients. However, recovery after lip cancer does not always mean that the fight is over; life after may be filled with uncertainty. Follow-up care is vital at this stage for early detection of recurrence and emotional recovery. The combination of structured surveillance, recognising risk factors and making mindful lifestyle changes paints a clearer picture of how quitting smoking or using daily sun protection can actively reduce lip cancer recurrence risk or second cancers moving forward. In addition, personalised education empowers survivors to take initiative in their health to pay attention to mental well-being. Follow-up care should be collaborative between both doctors and patients to strive to prevent cancer recurrence. It also helps individuals truly feel alive again, not just cancer-free, but also rediscover confidence and peace of mind.
