Skin Cancer
Skin cancer is a condition characterized by the abnormal growth of skin cells. It usually develops on skin exposed to the sun but can also occur in areas that are not typically exposed, such as the palms of the hands, soles of the feet, or genitals. There are three main types of skin cancer:
- Basal Cell Carcinoma (BCC): This is the most common type of skin cancer. It usually appears as a small, shiny bump or a red, scaly patch on the skin. BCC rarely spreads beyond the original tumor site but can cause significant damage if not treated promptly.
- Squamous Cell Carcinoma (SCC): SCC is the second most common type of skin cancer. It often looks like a firm, red nodule or a scaly, crusty sore. SCC can metastasize (spread) to other parts of the body if left untreated, although this is less common than with melanoma.
- Melanoma: Melanoma is less common than basal cell carcinoma and squamous cell carcinoma, but it is more dangerous because of its ability to spread rapidly to other parts of the body. Melanoma usually appears as a new mole or a change in an existing mole. It can vary greatly in appearance but is often characterized by irregular borders, uneven coloration, and a larger diameter than typical moles.
Risk factors for developing skin cancer include prolonged exposure to ultraviolet (UV) radiation from the sun or tanning beds, a history of sunburns, fair skin, a weakened immune system, and a family history of skin cancer.
Early detection and treatment are crucial for successful outcomes in skin cancer. Treatment options depend on the type and stage of the cancer but may include surgery, radiation therapy, chemotherapy, immunotherapy, or targeted therapy. Additionally, practicing sun safety measures such as wearing sunscreen, protective clothing, and avoiding excessive sun exposure can help reduce the risk of developing skin cancer. Regular skin examinations by a healthcare professional are also recommended, especially for individuals with a higher risk of skin cancer.

Understanding Skin Cancer
Skin cancer is a common type of cancer that develops in the skin cells. It often results from ultraviolet (UV) light exposure, such as sunlight. There are different types of skin cancer, including melanoma, basal cell carcinoma, and squamous cell carcinoma. Early detection is crucial for better treatment outcomes.
The ABCDE Checklist for Moles
The NHS recommends using the ABCDE checklist to help identify moles that could be cancerous. Each letter represents a specific characteristic to look out for:
- A - Asymmetry: One half of the mole does not match the other half in shape.
- B - Border: The edges of the mole are irregular, blurred, or jagged.
- C - Colour: The mole has varied shades of brown, black, tan, red, white, or blue.
- D - Diameter: The mole is larger than 6mm across (about the size of a pencil eraser).
- E - Evolving: The mole changes in size, shape, or colour over time.
Other Warning Signs
In addition to the ABCDE checklist, there are other warning signs that could indicate skin cancer:
- Itching or pain in a mole or the surrounding skin.
- A mole that bleeds, oozes, or forms a crust.
- An open sore that does not heal within a few weeks.
- A mole that looks significantly different from your other moles (also known as the "ugly duckling" sign).
When to See a GP
If you notice any of the above changes or have any concerns about a mole, it is important to see a GP as soon as possible. Early consultation can lead to better diagnosis and treatment. The GP may examine your skin and refer you to a specialist if necessary.
Prevention Tips
Prevention is key to reducing the risk of skin cancer. The NHS recommends the following tips:
- Use a broad-spectrum sunscreen with SPF 30 or higher.
- Wear protective clothing, including hats and sunglasses.
- Avoid tanning beds and excessive sun exposure.
- Regularly check your skin for any changes and follow the ABCDE checklist.
By staying vigilant and conducting regular skin checks, you can help detect skin cancer early and improve your chances of successful treatment.
Frequently Asked Questions
What are the signs that my mole might be skin cancer?
Signs of potential skin cancer in a mole include changes in size, shape, or color, irregular borders, multiple colors, itching or bleeding. Consult your GP if you notice any of these changes.
How can I tell if a mole is unusual?
Unusual moles, often referred to as dysplastic nevi, can be asymmetrical, have irregular borders, vary in color, be larger than 6mm, or change in appearance. Have any unusual moles checked by a doctor.
How often should I check my moles?
It is advisable to check your moles once a month. This helps to identify any changes early, which is crucial for the successful treatment of skin cancer.
What should I do if I notice a new mole?
If you notice a new mole and it appears unusual or different from your other moles, schedule an appointment with your GP for a professional evaluation.
What does the ABCDE rule stand for?
The ABCDE rule helps identify potential skin cancer: Asymmetry, Border irregularity, Color variation, Diameter greater than 6mm, Evolving in size, shape, or color.
Can skin cancer moles be flat?
Yes, skin cancer moles can be flat or raised. Both types require attention if they show signs of change or other unusual characteristics.
Are all dark moles cancerous?
Not all dark moles are cancerous. However, any mole that changes in color, shape, or size should be examined by a healthcare professional.
Is itching a sign of a cancerous mole?
Itching can be a sign of skin cancer but isn't always definitive. Any mole that becomes itchy, tender, or starts to bleed should be checked by a doctor.
What does a normal mole look like?
Normal moles are usually small (less than 6mm), round or oval, with smooth, well-defined borders and even color. They typically do not change over time.
What is the risk of moles developing into skin cancer?
The risk is generally low but can increase with factors such as excessive sun exposure, a large number of moles, family history of skin cancer, or having atypical moles.
Should I worry about a mole that has been there for years?
Moles that have been there for many years and have not changed in appearance are usually not a cause for concern. However, any changes should prompt a visit to the GP.
How can I protect my moles from becoming cancerous?
To protect your moles, avoid excessive sun exposure, wear sunscreen with high SPF, cover up with clothing, and avoid tanning beds.
When should I see a GP about a mole?
You should see a GP if a mole changes in size, shape, or color, itches, bleeds, or looks different from other moles.
Can a skin cancer mole heal on its own?
Skin cancer moles do not heal on their own. If you suspect a mole is cancerous, seek medical advice as early treatment is crucial.
How is skin cancer diagnosed if a mole is suspected?
If skin cancer is suspected, a GP may refer you to a dermatologist who may perform a biopsy to examine the suspicious mole.
