What is Skin Cancer?

Skin cancer happens when skin cells start to grow out of control, and this is usually because of DNA damage from ultraviolet (UV) radiation. This damage can cause mutations that make the cells multiply rapidly. It’s a common misconception that only people with fair skin are at risk. In reality, skin cancer can affect anyone, regardless of skin tone. 

Understanding the stages of skin cancer is crucial. These stages range from 0, also known as in situ, where the cancer is just in the outer layer of the skin, to stage IV, where the cancer has spread to other parts of the body. The higher the stage, the more intensive the treatment required. Being aware of these stages helps in recognising the importance of early detection and treatment.

Types of Skin Cancer

There are several types of skin cancer. Here is a quick view of each type with unique characteristics:

1. Basal Cell Carcinoma (BCC): The most common type, usually appearing as a small, shiny bump on sun-exposed areas.
2. Squamous Cell Carcinoma (SCC): Often looks like a red, scaly patch or sore that doesn’t heal.
3. Melanoma: The deadliest form, characterised by dark, irregular moles or spots.

Other Rare Types: Includes Merkel cell carcinoma and dermatological protuberant (DFSP).

How to Spot Skin Cancer

Detecting skin cancer early can make a significant difference in treatment outcomes. But how to spot it? Look for the following signs and symptoms and easily identify the skin cancer at its early stages.:

Early Signs and Symptoms

• Pay attention to any new spots or lumps on your skin, especially those that appear pearly, translucent, tan, brown, black, or multicoloured. 
• If you have a sore or wound that doesn’t heal within a few weeks, it could be a sign of skin cancer. Especially those that bleed, ooze, or become crusty, should be checked by a dermatologist.
• Monitor your moles for any changes in size, shape, colour, or texture. Moles that become itchy, tender, or painful, or those that start to bleed, should be evaluated by a doctor.

ABCDEs of Melanoma

The ABCDE rule is a helpful guide for identifying the warning signs of melanoma, the most serious type of skin cancer. Examine your moles and spots for the following characteristics:

• Asymmetry (A): Non-cancerous moles are usually symmetrical, while melanoma lesions tend to have an irregular shape.
• Border Irregularity (B): Normal moles have smooth, even borders, whereas the borders of melanomas are often uneven.
• Color Variation (C): The colour is not uniform and may include shades of brown, black, tan, red, white, or blue. 
• Diameter Over 6 mm (D): The mole or spot is larger than 6 millimetres across (about the size of a pencil eraser). It’s important to note that melanomas can be smaller when first detected, so any significant change in size should be taken seriously.
• Evolving Shape or Color (E): The mole or spot is changing in size, shape, colour, or elevation, or new symptoms such as bleeding, itching, or crusting develop. 

Diagnosis Process of Skin Cancer

Once you spot signs of skin cancer, don’t wait—visit your dermatologist promptly. They will perform a thorough diagnosis, which typically involves a detailed skin examination and, if necessary, a biopsy to analyse a sample of the suspicious area.

1. Skin Examination

During a skin examination, a dermatologist will conduct a thorough visual inspection of your skin. They will look for any unusual growths, moles, or changes in your skin’s appearance using a dermatology.

2. Biopsy Procedures

If the dermatologist identifies a suspicious area, they will likely recommend a biopsy to confirm whether it is cancerous or not. The types of biopsy procedures include:

• Shave Biopsy: The top layers of the skin are shaved off for examination.
• Punch Biopsy: A circular tool is used to remove a small, deep sample of skin.
• Excision Biopsy: The entire lesion or growth is removed, often with some surrounding tissue.
• Incision Biopsy: Only a portion of the suspicious area is removed for analysis.

The tissue sample is then sent to a laboratory where a pathologist examines it under a microscope to determine if cancer cells are present.

3. Dermatologist’s Role

The dermatologist assesses the biopsy results, determines the type and stage of skin cancer if present, and discusses the most appropriate treatment options with you. 

Ingredients and Chemicals That May Increase the Risk of Skin Cancer

Certain ingredients and chemicals in everyday products can increase the risk of skin cancer. Experts suggest avoiding prolonged exposure to:

Being aware of these substances and reducing exposure can significantly contribute to skin cancer prevention.

How to Prevent Skin Cancer

Finally, we’ve reached the heart of our blog. Here are a few ways to protect yourself from skin cancer. Let’s dive into each prevention method in detail!

1. Seek the Shade

The sun emits two types of harmful rays, UVA and UVB. UVA rays penetrate deeply into the skin, leading to premature aging and DNA damage while UVB rays are responsible for sunburns and also damage the DNA in skin cells. Over time, repeated exposure to these rays can cause uncontrolled growth and the development of cancer. Spending time in the shade, especially between 10 a.m. and 4 p.m. when the sun’s rays are strongest, helps protect your skin from harmful UV radiation. Whether you’re at the beach, park, or just outside for errands, finding shade under umbrellas, trees, or other shelters reduces your overall exposure.

2. Wear Protective Clothing

Choosing the right clothing can significantly shield your skin from UV rays. Opt for tightly woven fabrics that cover as much skin as possible. Long-sleeved shirts, pants, wide-brimmed hats, and sunglasses with UV protection are essential. These not only protect but also keep you comfortable and stylish outdoors.

3. Use Broad-Spectrum Sunscreen

Sunscreen is your frontline defense against skin cancer. Look for broad-spectrum sunscreen with an SPF of 30 or higher. Apply it generously to all exposed skin, even on cloudy days or in winter. Remember to reapply every two hours or immediately after swimming or sweating to maintain effective protection.

4. Avoid Tanning Beds

Tanning beds and sunlamps emit UV rays, often in much higher concentrations than natural sunlight. Using tanning beds before the age of 35 increases the risk of melanoma by 59%. The more frequent the use, the higher the risk. So, Instead of preferring artificial tanning methods, opt for sunless tanning products or bronzes that provide a safer alternative for achieving a tan without risking your skin’s health.

5. Be Extra Cautious Near Water, Snow, and Sand

Reflective surfaces like water, snow, and sand can intensify the sun’s UV rays, leading to increased exposure. Whether you’re swimming, skiing, or enjoying a day at the beach, take extra precautions.

6. Get Vitamin D Safely

Vitamin D is essential for bone health and overall well-being. While sunlight is a natural source of vitamin D, it’s important to obtain it safely without risking skin damage. Balance your sun exposure by getting vitamin D through a healthy diet, supplements, or brief periods of outdoor activity.

7. Check Your Skin Regularly

Performing regular self-examination of your skin helps you detect any changes early. Look for new moles, growths, or changes in existing ones. Use mirrors or ask a family member to check hard-to-see areas like your back or scalp. If you notice anything unusual, consult a dermatologist promptly.

8. Eat a Balanced Diet to Support Skin Health

Your lifestyle choices play a significant role in your overall skin health. Eating a balanced diet rich in antioxidants can help support your skin and boost your immune system. Foods like berries, nuts, and leafy greens are excellent options. Staying hydrated is also vital for maintaining healthy skin, so drink plenty of water throughout the day. Moreover, avoiding smoking and limiting alcohol consumption can further protect your skin from damage and reduce your risk of skin cancer.

9. Spread Awareness

Finally, educating yourself and others about the importance of skin cancer prevention can make a big difference. Spread awareness by sharing information on safe sun practices with your friends and family. By becoming an advocate for skin cancer prevention, you can help create a community that prioritizes skin health and reduces the incidence of this preventable disease.

10. Stay Informed and Updated

Skin cancer research and prevention strategies are continually evolving. Stay informed by keeping up with the latest news and recommendations from reputable health organisations. Regularly check sources like the American Cancer Society or the Skin Cancer Foundation for updates. Knowledge is power, and staying educated helps you make informed decisions about your health and safety.
