What is skin cancer screening?
Skin cancer screening is a visual examination of the skin before a person has noticed definite cancer symptoms.
During a clinical skin examination, a dermatologist looks for spots or growths that may require:
- Monitoring
- Dermoscopic or magnified assessment
- Clinical photography
- Biopsy
- Removal
- Referral for specialist cancer care
Visual examination by a healthcare professional and skin self-examination are the main proposed methods of screening for skin cancer.
What is the “ugly duckling” sign?
The ugly-duckling sign refers to a mole or spot that looks noticeably different from the patient’s other lesions.
It may be:
- Darker
- Lighter
- Larger
- More irregular
- Raised when others are flat
The only spot changing
The only lesion itching or bleeding
A lesion does not need to satisfy every ABCDE criterion to deserve assessment. A spot that looks different from the rest or changes over time is an important warning sign.
Types, options and detailed guidance
Is screening different from checking a suspicious mole?
Yes.
Screening generally means examining someone who has no specific suspicious symptom.
Diagnostic assessment means examining a particular lesion because it is:
- New
- Changing
- Bleeding
- Itching
- Painful
- Crusted
- Growing
- Failing to heal
A changing or symptomatic lesion should not wait for a routine screening programme. It requires timely clinical assessment.
Does routine screening prevent death from skin cancer?
The evidence is not conclusive for universal population-wide screening of every asymptomatic adult.
The US Preventive Services Task Force and the National Cancer Institute state that evidence remains insufficient to determine whether routine visual screening of the general asymptomatic population reduces skin-cancer mortality. This does not mean suspicious lesions should be ignored, and it does not apply in the same way to people with symptoms, previous skin cancer or other important risk factors.
Routine annual screening is not required for every adult, and screening cannot guarantee prevention.
What are the main types of skin cancer?
Basal cell carcinoma, or BCC, commonly grows slowly and rarely spreads to distant parts of the body. Untreated lesions can nevertheless invade surrounding skin and tissue.
Squamous cell carcinoma, or SCC, may appear as a rough patch, firm growth, crusted bump or non-healing sore. Some SCCs can grow deeply or spread, particularly in patients with reduced immunity.
Melanoma is less common than BCC and SCC but has a greater tendency to spread. Outcomes are generally better when it is identified before it grows deeply or spreads elsewhere.
What can basal cell carcinoma look like?
Possible BCC appearances include:
- A shiny or pearly bump
- A firm round growth
- A brown, black, blue-grey or skin-coloured bump
- A sore that does not heal
- A sore that heals and returns
- A scaly patch
- A scar-like mark without previous injury
- A lesion with fine visible blood vessels
- A growth that bleeds or crusts repeatedly
BCC can be pink or red on lighter skin and may appear brown, black, blue-grey or skin-coloured on deeper skin tones.
What can squamous cell carcinoma look like?
Possible SCC appearances include:
- A rough or scaly patch
- A firm dome-shaped growth
- A crusted lump
- A wart-like growth
- A horn-like projection
- A sore with raised borders
- A wound that fails to heal
- A lesion that heals and returns
- A changing area within an old scar
- A growth that bleeds or becomes tender
SCC can occur on sun-exposed skin, but it may also arise inside long-standing wounds, burns or scars.
What can melanoma look like?
Melanoma may appear as:
- A new mole-like spot
- A changing existing mole
- A freckle or age spot that looks different from the others
- A lesion with irregular borders
- A spot containing several colours
- A rapidly growing firm bump
- A pink or red lesion with little visible pigment
- A dark streak beneath a nail
- Pigmentation spreading onto skin around a nail
- A sore that does not heal
Melanoma is not always dark brown or black and may occasionally appear pink, red or skin-coloured.
What are the ABCDE warning signs?
A — Asymmetry
One half of the lesion looks different from the other.
B — Border
The border is irregular, scalloped, blurred or poorly defined.
C — Colour
Different areas contain varying shades of brown, black, tan, red, blue, grey or white.
D — Diameter
Many melanomas are larger than 6 mm when diagnosed, but melanoma can be smaller.
E — Evolving
The spot changes in size, shape, colour, elevation or symptoms.
A lesion showing an ABCDE feature should be examined by a dermatologist.
Does a suspicious mole always hurt?
No.
Early skin cancer may cause no pain, itching or discomfort. The only sign may be a visible change.
Some lesions later become:
- Painful
- Tender
- Itchy
- Numb
- Sensitive
- Crusted
- Bleeding
The absence of pain does not confirm that a growth is harmless.
Does every changing mole mean cancer?
No.
- Normal growth
- Hormonal change
- Pregnancy
- Friction
- Inflammation
- Injury
- Ageing
- Benign seborrhoeic keratosis
- Another non-cancerous skin condition
A changing mole still deserves examination because appearance alone cannot always distinguish benign change from melanoma.
Can a non-healing sore be skin cancer?
Yes.
A sore that:
- Does not heal
- Repeatedly crusts
- Bleeds with minor contact
- Heals and returns
- Becomes gradually larger
- Develops a raised border
may represent BCC, SCC or another condition requiring biopsy.
A non-healing wound may also result from infection, diabetes, poor circulation or repeated injury, so diagnosis should not be assumed from appearance alone.
Can a rough patch be precancerous?
Yes.
Actinic keratosis is a sun-damaged rough or scaly growth that can occasionally progress to squamous cell carcinoma. Persistent rough patches on the face, scalp, ears, lips, forearms or hands should be examined, particularly when they become thick, tender, crusted or enlarged.
Additional care and practical advice
Can skin cancer occur in Indian or brown skin?
Yes.
People with brown or deeply pigmented skin have a lower overall risk of some UV-related skin cancers than people with very fair skin, but they can still develop BCC, SCC and melanoma. Skin cancer in darker skin may also arise on areas that receive little sunlight.
Important areas to inspect include:
- Palms
- Soles
- Between toes
- Fingernails and toenails
- Skin around the nails
- Mouth and lips
- Scalp
- Buttocks
- Genital skin
- Long-standing scars and wounds
Diagnosis before cosmetic removal
A changing mole is not automatically frozen, lasered or cauterised before cancer has been considered.
Indian-skin considerations
The examination includes areas such as the palms, soles, nails and chronic scars, which can be important in brown skin.
Biopsy when clinically required
Skin biopsy is available at both Karan Nagar and Paloura.
Referral when specialist cancer care is needed
Patients can be directed to an appropriate surgical, oncology or hospital pathway when a lesion requires care beyond the clinic’s verified scope.
Realistic communication
A clinical skin check does not guarantee that every cancer will be detected or that every lesion requires removal.
A changing mole or non-healing sore should be examined before it is removed cosmetically
Book a skin cancer screening or suspicious-lesion consultation with Dr. Cheena Langer at Aastha Skin & Dermato-Cosmetic Centre, Jammu.
Additional cost depends on:
- Whether one lesion or several areas need assessment
- Clinical photography
- Biopsy technique
- Histopathology charges
- Wound dressings
- Complete lesion removal
- Repeat or wider excision
- External surgical or oncology referral
- Follow-up after the included 10-day period
A biopsy is not automatically required for every mole. The need and cost are explained after examination.
How care is planned
- Assessment comes before treatment selection.
- Options, limitations, aftercare and expected timelines are explained.
- The plan is adapted to diagnosis, skin type and medical history.

Frequently asked questions
What nail changes should be checked?
Arrange assessment for:
- A new brown or black streak
- A streak that becomes wider
- Irregular colour within a nail band
- Pigment spreading onto nearby skin
- A nail that splits without explanation
- Nail lifting
- A persistent lump beneath a nail
- A wound around a nail that does not heal
- Repeated bleeding beneath a nail
Many nail streaks are benign, particularly in darker skin, but melanoma can develop beneath or around a nail and may initially resemble a bruise.
What changes on the palms or soles need assessment?
Seek evaluation for:
- A new irregular dark patch
- A spot with several colours
- A lesion that grows
- A non-healing sore
- A wound mistaken for a corn
- A dark area beneath thick callused skin
- Repeated bleeding
- A lesion that does not respond as expected to wart treatment
Acral melanoma may develop on the palms, soles, fingers, toes or nail beds, including in people with darker skin.
Who has a higher risk of skin cancer?
Risk may be increased by:
- Previous skin cancer
- Family history of melanoma
- Numerous moles
- Atypical moles
- Fair skin that burns easily
- Red or blond hair
- Repeated sunburns
- Long-term ultraviolet exposure
- Outdoor occupation
- Indoor tanning
- Reduced immunity
- Organ transplantation
- Photosensitising medicines
- Certain inherited conditions
- Long-standing wounds or burn scars
Ultraviolet exposure is a major cause of BCC, SCC and melanoma, although not every skin cancer—particularly acral melanoma—is linked to UV exposure.
Who may benefit from an individualised skin-check plan?
A risk-based discussion may be particularly useful for someone who:
- Has previously had melanoma, BCC or SCC
- Has had an atypical mole removed
- Has many moles
- Has a strong family history
- Takes long-term immune-suppressing medicine
- Has received an organ transplant
- Has extensive sun damage
- Works outdoors
- Has a suspicious lesion
- Has a wound or scar that is changing
- Has difficulty checking their own skin
The frequency of professional examination should be based on personal risk and previous findings rather than one identical timetable for everyone.
How often should skin cancer screening be done?
There is no single evidence-based interval suitable for every asymptomatic adult.
The appropriate schedule may depend on:
- Previous skin-cancer history
- Number and type of moles
- Family history
- Immune status
- Previous biopsy findings
- Amount of sun damage
- Age
- Ability to perform self-examination
Patients with previous melanoma or another important risk factor may require a structured follow-up schedule from their treating specialist.
What happens during a skin cancer screening examination?
A consultation may include:
- Reviewing the patient’s concern and risk factors
- Asking about previous skin cancer or biopsies
- Reviewing family history
- Examining the suspicious lesion
- Comparing it with surrounding moles or spots
- Checking for ABCDE changes
- Looking for BCC and SCC warning signs
- Examining nails, palms or soles when relevant
- Assessing scars and non-healing wounds
- Using magnification or dermoscopy where available
- Taking clinical photographs with consent
- Recommending monitoring, biopsy or referral
The extent of the examination depends on the patient’s concern, consent, medical history and individual risk.
Does a full-body examination include private areas?
Skin cancer can occur anywhere, but examination must remain clinically appropriate and consent-led.
Before examining a sensitive area, the clinician should explain:
- Why it may need examination
- What the examination involves
- Whether a chaperone is available
- Which clothing needs to be moved or removed
- That the patient may decline or pause the examination
Only areas relevant to the consultation and agreed to by the patient should be examined.
