When should you get tested for skin cancer?

Skin cancer is on the rise in the UK, but the good news is that early detection significantly improves the chances of successful treatment.

You should get tested for skin cancer if you notice a new, changing, or unusual mole, mark, or patch of skin, or if you are at higher risk, e.g., you have a family history of skin cancer or lots of moles. Dermatologists' guidelines recommend annual skin checks for most adults.

Not every mole, mark or skin change is serious. But knowing what to look for - and when to get checked - can make all the difference. Skin cancer screening is quick, simple and reassuring. And importantly, you don’t need to wait for symptoms to take action.

Is skin cancer in the UK common?

Statistics show that skin cancer is now one of the fastest-rising cancers in the UK. This is often attributed to increasing exposure to UV radiation from the sun (and sunbeds), but greater awareness and earlier diagnoses are also factors in rising numbers.

The reassuring news is that skin cancers can be treated successfully if they are identified and diagnosed early. So it's very important to take changes to your skin seriously and conduct regular checks. This helps you understand your 'normal' so you can seek advice if you notice anything new or different.

TYPES OF SKIN CANCER

What are the main types of skin cancer?

There are two main categories of skin cancer:

• Non-melanoma skin cancer - A common form of cancer that usually affects areas exposed to the sun, such as the face, scalp and hands. It includes:
  • basal cell carcinoma, the most common form, and
  • squamous cell carcinoma (SCC), the second most common type.
• Melanoma skin cancer - A more dangerous form of skin cancer, which can spread to other parts of the body. However, if it's caught early, there are more treatment options, and outcomes can be significantly improved.

What is the difference between melanoma and non-melanoma skin cancer?

Melanoma develops in the pigment-producing cells of the skin and often appears as a new mole or a change to an existing mole. Although less common, it is considered more serious because it can spread to other parts of the body if not identified early.

Non-melanoma skin cancers are more common and usually develop slowly in areas regularly exposed to the sun. They may appear as a sore that does not heal, a scaly patch or a persistent lump rather than a changing mole. While they are often very treatable, early assessment is still important.

SKIN CANCER: RISKS, CAUSES & PREVENTION

Who is at high risk of skin cancer?

Your risk of skin cancer is higher if you:

• Have fair skin that burns easily
• Have a large number of moles
• Have a personal history or family history of cancer
• Spend a lot of time in the sun or use sunbeds
• Have a weakened immune system

Understanding your risk can help you take sensible steps to protect your skin and feel more confident about what to look out for.

What causes melanoma skin cancer?

Studies suggest that around 90% of melanoma cases are linked to exposure to ultraviolet (UV) radiation from the sun or sunbeds.

Repeated sun exposure increases risk and can damage the skin over time, leading to cancer development. Protecting your skin from the sun is one of the most effective ways to reduce your risk.

Practical ways to protect your skin from the ultraviolet (UV) light:

• Use a broad-spectrum sunscreen with at least SPF 30 and reapply regularly
• Spend time in the shade during the hottest part of the day, typically between 11am and 3pm
• Wear long-sleeve clothing, sunglasses and a wide-brimmed hat
• Avoid using sunbeds or tanning lamps
• Take extra care near water, sand and snow, which can reflect UV rays
• Protect children’s skin carefully, as sun damage early in life can increase future risk
• Be aware that UV rays can still damage skin on cloudy days, particularly during spring and summer in the UK

CHECKING FOR SKIN CANCER

What are the seven warning signs of skin cancer?

Recognising the warning signs of skin cancer is key to early detection.

Check your skin regularly for:

1. Asymmetric moles: Where one half of the mole doesn't match the other in colour or shape.
2. Ragged borders: Moles where the edges are blurred or scalloped.
3. Colour changes: Moles that develop multiple shades of tan, brown, black, or even patches of red, white, and blue.
4. Diameter: The spot is larger than 6mm (though some cancers can be smaller).
5. Changing size, colour or shape: A mole that changes over a short period.
6. Non-healing Sores: A crusty or scaly sore that bleeds, oozes, or doesn't heal after a few weeks.
7. Uncomfortable or painful sensations: A spot that suddenly starts itching, tingling, or becoming tender to the touch.

The 'ugly duckling' rule is helpful - if one mole looks different from your other moles, it should be checked.

How to check your skin at home

A thorough self-examination once a month can help you identify skin changes early. It’s simple, convenient and can help you feel more familiar with what is normal for your skin, making it easier to spot anything new, changing or unusual.

Use a full-length mirror in a well-lit room to check all areas of your body, including your back and scalp. Use a hand mirror for more difficult-to-see areas.

Look carefully at your skin texture and look for any abnormal areas or changes in existing moles. Taking some quick photos on your phone can help you track changes over time.

What is the two-week rule for skin cancer?

The two-week rule is a practical guideline: if you notice any unusual skin changes or symptoms that persist for more than two weeks, you should see a doctor.

This includes non-healing sores, a new mole, or an abnormal area of skin that does not improve. Seeking advice early can improve treatment options and outcomes if further investigation is needed.

At what age should you start getting checked for skin cancer?

Many dermatologists recommend becoming familiar with your skin from early adulthood and carrying out regular skin checks, particularly if you are at higher risk (see more on the risks above). If you have a personal history of skin cancer, you may need regular screenings by a dermatologist or skin specialist.

How often should you have skin cancer screening?

For most people, an annual skin exam is recommended. While the NHS does not currently offer routine screening, you can easily book an appointment at a dedicated skin clinic, and many dermatologists can recommend baseline tests to establish what is normal for your skin.

What happens during a skin cancer test?

During a skin cancer assessment, a dermatologist or other skin cancer specialist will carefully examine moles, marks, or other areas of skin that are concerning. They may use a specialist magnifying tool called a dermatoscope to look more closely at the skin’s surface.

If further investigation is needed, they may recommend a skin biopsy, where a small sample is removed and sent to a laboratory for analysis. This helps provide a clearer diagnosis and guides the most appropriate next steps, whether that is reassurance, monitoring or treatment.

Frequently asked questions about getting tested for skin cancer

Do I need anything more than skin cancer screening?

For most people, a professional skin cancer screening combined with regular self-checks is the most effective approach.

A specialist assessment allows any suspicious areas to be identified and, if needed, referred for further investigation quickly. You don’t need to navigate multiple tests yourself; the important step is getting any concerns checked by an expert.

What is mole mapping?

Mole mapping is a specialist skin monitoring technique that uses detailed photographs to track changes in moles over time. It's not necessary for everyone, only those at high-risk, e.g., those with a history of skin cancer, a family tree that includes melanoma, or lots of moles. If you only have a few moles, a simple annual skin check and regular self-screening are usually enough.

What happens if something suspicious is found?

At Check4Cancer, we are here to support you beyond the initial examination. If your specialist identifies an area of concern, they will explain it to you carefully and discuss the next steps. This may include further assessment or referral for diagnostic tests.

Can I get checked for skin cancer even if I don’t have symptoms?

Yes, and many people do. Skin cancer screening is designed for people who don’t necessarily have symptoms but want reassurance or to catch any issues early. You don’t need to wait for something to feel wrong before booking a check.
