Skin Cancer: Early Detection Saves Lives

Understanding Skin Cancer and the Importance of Prevention

Skin cancer is one of the most common types of cancer in the United States. 

It affects millions of people, with new cases being diagnosed each year. 

The alarming part? Skin cancer is often preventable, and early detection can significantly improve outcomes. 

However, many people still overlook the importance of regular skin checks and sun protection.

What Exactly is Skin Cancer?

Skin cancer occurs when abnormal skin cells grow uncontrollably, forming tumors. 

The main types you’ll encounter are:

• Basal Cell Carcinoma (BCC) and Squamous Cell Carcinoma (SCC): These skin cancers are commonly seen in sun-exposed areas and when treated early, have good outcomes.

• Melanoma: The most dangerous form, melanoma has the potential to spread to other parts of the body, making it a serious concern for both patients and practitioners.

Who’s Most at Risk?

While skin cancer can affect anyone, certain groups are more vulnerable:

1. Fair Skin: People with lighter skin tones, particularly those with blonde or red hair and blue or green eyes, are at a higher risk due to the lack of melanin, which provides some protection from harmful UV rays.

2. Sun Exposure History: Those who’ve spent extended periods in the sun or used tanning beds, especially without protection, increase their risk. A history of sunburns—especially blistering ones—also raises the chances of developing skin cancer later in life.

3. Family History: If someone in your family has had skin cancer, you may be more likely to develop it as well.

4. Age and Gender: While skin cancer can occur at any age, the risk increases with age. Additionally, men, particularly older men, tend to develop melanoma more frequently than women.

Skin Cancer Symptoms: What to Watch For

As dermatology students, you’re well aware that skin cancer can present in various forms. The most important thing is identifying abnormal changes in the skin. The American Academy of Dermatology recommends looking for the ABCDEs of melanoma:

• Asymmetry: One half of the mole doesn’t match the other.

• Border: The edges of the mole are irregular or jagged.

• Color: Multiple colors within a single mole.

• Diameter: Larger than 6mm (about the size of a pencil eraser).

• Evolving: Any noticeable changes over time.

Prompt recognition and early intervention are key. Encourage your patients to monitor their skin regularly and seek a dermatological evaluation if they notice any of these signs.

The Importance of Early Detection

Skin cancer diagnosis is time-sensitive. Delays in detection, particularly for melanoma, can lead to worse prognoses. Unfortunately, the rise in dermatology wait times is contributing to longer delays.

• The average wait time for a dermatology appointment is 34.5 days, and in some areas like Portland, it can extend to over 84 days.

• The survival rate for melanomas detected before spreading is 99%. But once melanoma reaches the lymph nodes, survival drops to 68%, and if it spreads further, it can drop to as low as 18%.
