You notice a spot while getting dressed. Perhaps it seems darker than you remember, catches on clothing or looks different from the moles around it. The next question is often whether to book an appointment, take a photograph or wait to see what happens.
A spot that is changing, looks unlike your other spots, repeatedly bleeds or does not heal should be assessed by a healthcare professional. You do not need to decide whether it is cancer before asking for help. Many skin changes have non-cancerous explanations; an examination is how that distinction is investigated. The AAD’s skin self-examination guidance explains which changes deserve attention.
At Elevate Dermatology in Pickering, changing moles and other concerning lesions belong with our medical dermatology team. Our board-certified dermatologists assess skin concerns, including possible skin cancer. This guide explains what changes to look for, when to seek medical assessment and how to prepare for your appointment.
What is a mole, and why can it change?
Moles are growths formed by clusters of pigment-producing cells. Their appearance varies, and some changes can occur over a person’s lifetime. A raised mole is not automatically dangerous, and a flat spot is not automatically harmless. Context and examination matter. The AAD’s information on moles describes their usual features.
Patients also use “mole” to describe freckles, sun spots, skin tags and other growths. Those are not all the same thing. If you are unsure what a spot is, describing its location, timing and behaviour is more helpful than trying to label it accurately before your appointment.
A useful starting point is your own pattern. If most of your moles resemble one another but one looks markedly different, mention that. The comparison can be relevant even if the unusual spot is small or painless.
The ABCDE signs of melanoma
The ABCDE guide is a memory aid for changes that warrant attention. It cannot diagnose melanoma or rule it out.
| Letter | What to look for |
|---|---|
| A: Asymmetry | One half does not resemble the other |
| B: Border | Edges are uneven, poorly defined or irregular |
| C: Colour | Different colours appear within the same spot, or its colour changes |
| D: Diameter | A larger spot can be concerning, but melanoma can also be smaller than 6 mm |
| E: Evolving | A change in size, shape, colour or behaviour over time |
Do not wait for every feature to appear. A small lesion can deserve evaluation, and a concerning change may be more informative than any single measurement. The AAD’s ABCDE guide includes illustrations and explains the limits of the diameter rule.
When telling us about a change, be specific: “This spot has enlarged since March” is clearer than “I have an odd mole.” Explain if it has begun bleeding, feels different or has become noticeably raised.
Warning signs beyond the ABCDE checklist
Not every skin cancer resembles a dark, irregular mole. A persistent scaly area, a repeatedly crusting or bleeding growth, or a sore that does not heal can also need assessment. Skin cancer can occur on areas that are not routinely exposed to the sun. The Canadian Cancer Society describes signs of non-melanoma skin cancer.
This is why a home check should not focus only on familiar brown spots. Pay attention to what is new or persistently different. A lesion that seems to heal and then breaks down again is worth mentioning rather than restarting the waiting period each time.
Pain is not a reliable way to decide whether a spot matters. A concerning lesion may be painless. Equally, irritation from clothing can make a benign growth uncomfortable. The appropriate next step is assessment, not a conclusion based on one symptom.
How to check your skin without becoming overwhelmed
Choose good light and use a full-length mirror plus a hand mirror, or ask someone you trust to help with areas you cannot see. Include the scalp, back, palms, soles, nails and spaces between the toes. The aim is familiarity with your skin, not repeated inspection of the same spot throughout the day.
A simple body map or dated photographs can help you remember locations. Note the date you first noticed a change and whether symptoms have been continuous or intermittent. Avoid spending hours comparing your skin with image search results: photographs online cannot account for your history or reliably provide a diagnosis.
If you take a picture, include enough surrounding skin to locate the lesion and a closer view that is in focus. Use consistent lighting where possible. A photograph can support the clinical history; it should not delay an appointment for a concerning change.
Ask your clinician how often self-checks and professional examinations make sense for your risk profile. There is no single examination schedule appropriate for everyone.
Who may need closer surveillance?
A personal history of skin cancer, a family history of melanoma, many or atypical moles, significant UV exposure and previous severe sunburns can affect risk assessment. Certain medical conditions or treatments may also influence the follow-up plan. The Canadian Cancer Society outlines melanoma risk factors.
When preparing for your appointment, include this history even if your main concern is one small spot. Tell our team about previous skin cancer or biopsies and relevant family history. If you do not know the exact diagnosis, say so; you do not need to reconstruct the history perfectly before seeking advice.
Having darker skin does not remove the need to assess a changing lesion. Nor does having very few moles guarantee that a new growth is unimportant. Risk factors guide the conversation; a specific concerning change still deserves attention on its own merits.
What happens at a skin examination?
An appointment usually begins with the reason for the visit and relevant history. You may be asked when a lesion appeared, how it has changed, whether it bleeds or itches, and whether you have had previous biopsies or skin cancer.
The clinician examines the area and may recommend a broader skin examination. A dermoscope, a handheld instrument with light and magnification, can help reveal structures that are difficult to see with the naked eye. It is an examination tool, not a guarantee that every diagnosis can be made without further testing. The Canadian Cancer Society explains examination and dermoscopy.
You can ask what areas will be examined, how privacy will be maintained and whether a chaperone is available. Mention any area you want specifically checked; do not assume a lesion concealed by hair, clothing or a nail product will be obvious.
An examination may lead to reassurance, monitoring, further assessment or a recommendation for biopsy. The reason for that recommendation should be explained in terms you understand.
Does a biopsy mean the clinician thinks I have cancer?
A biopsy is a way to obtain tissue for laboratory examination when more information is needed. It does not itself establish a cancer diagnosis. The type of sample depends on the lesion and clinical question. The Canadian Cancer Society’s diagnostic guide describes this process.
If a biopsy is recommended, ask about local anaesthetic, wound care, activity restrictions and the expected result process. Before leaving, know who will communicate the result and when to contact the clinic if you have not heard back.
Avoid interpreting silence as a result. A clear follow-up arrangement is part of the care plan. If another procedure is needed after the report, the next step should be based on the findings rather than assumed in advance.
Preparing for a mole check in Pickering
A short list makes it easier to cover your concerns:
- The location of each spot you want assessed.
- When you noticed it and the changes you have observed.
- Dated photographs, if available.
- Previous biopsy reports or the name of the clinic that performed them.
- Your medication list and relevant personal or family history.
When contacting Elevate Dermatology, say clearly if you have a changing, bleeding or nonhealing lesion. Our clinic offers cosmetic care as well, so identifying this as a medical concern helps our team explain the relevant booking requirements. If you are coming from Ajax, Whitby or Oshawa, confirm the referral and appointment details before travelling.
If you are waiting for an appointment and the lesion changes further, update the referring clinician or clinic. They can reassess the information and advise on the appropriate pathway. Do not wait for a seasonal “annual check” simply because it is already in the calendar.
Medical assessment and cosmetic removal are different decisions
A growth can bother you cosmetically even when it is benign. However, identifying it comes before choosing how to remove it. Do not apply home removal products, burn it off or arrange cosmetic laser treatment for an unexplained pigmented lesion.
At Elevate Dermatology, our dermatologists can assess an unexplained growth before you explore cosmetic removal. This is an important distinction within our team approach: an aesthetic concern about a spot does not replace the medical question of what it is. Ask about the diagnosis and any recommended testing before considering how you would like the area to look.
Learn more about our medical dermatology services or contact our team to clarify the appropriate booking pathway for your concern.
Frequently asked questions
Should every adult have a yearly mole check?
A regular schedule should reflect personal risk and clinical advice. A person with previous melanoma may need a different follow-up plan from someone without that history. Regardless of schedule, report a new concerning change when it appears.
Can a small mole be melanoma?
Yes. The 6-mm point in the ABCDE guide is not a safe cutoff. Changes and the overall appearance matter, so do not dismiss a lesion because it is smaller than a pencil eraser.
What if a mole has been there for years?
Longstanding lesions can still deserve assessment if they change. Tell the clinician both how long it has been present and what is different now. A dated earlier photograph may help document that change.
Can I send a photograph instead of being examined?
Ask our team whether photographs may be useful for triage. They may help communicate a concern, but lighting, focus and the limits of an image can prevent a reliable assessment. An in-person examination or biopsy may still be necessary.
Should I worry if a mole catches on clothing?
Friction can irritate a growth, but recurrent bleeding or a change should still be discussed. Explain whether the bleeding follows a clear injury or happens without one. Avoid repeatedly picking or manipulating it while waiting for advice.
Does a skin check hurt?
Looking at the skin and using a dermoscope is generally straightforward. If a procedure is recommended, the clinician should explain it separately, including comfort measures. You can ask questions before deciding how to proceed.
What if the spot looks normal on the day of the visit?
Keep the appointment if there has been a concerning pattern. Bring photographs and describe what happened between visits. An intermittent symptom is still part of the history even when it is not visible that day.
A clear next step for a changing spot
For a changing mole or persistent lesion, start with medical assessment. You can speak with your primary care clinician or contact our team at Elevate Dermatology to clarify the appointment pathway. Let us know what changed and when; do not book an aesthetic treatment in place of assessment of a concerning spot.
Being prepared does not mean arriving with an answer. It means knowing what changed, sharing the relevant history and leaving with a clear understanding of any monitoring, testing or follow-up that is needed.
