Worried About a Mole? Why Early Skin Cancer Detection Saves Lives

With 3.5 million skin cancers diagnosed annually in the US (exceeding breast, colon, lung, and prostate cancers combined), early detection is crucial—particularly for melanoma, the deadliest form that causes 75% of skin cancer deaths yet is most curable when caught early, often appearing as new spots rather than changes to existing moles. Prevention combines genetic awareness with sun protection practices including broad-spectrum sunscreen application, avoiding peak sun hours (10am-2pm), and skipping tanning beds, while detection requires both monthly self-examinations and annual full-body checks by board-certified dermatologists who can identify and treat concerning spots before they become life-threatening.

Worried About a Mole? Why Early Skin Cancer Detection Saves Lives

Why Early Diagnosis of Skin Cancer Matters

Look at your skin. Do you have a mole or a spot that you're worried about? You're not alone. Every day, I see patients who worry they might have skin cancer. While some people seek professional advice right away, others tend to procrastinate. When it comes to skin cancer, early diagnosis is crucial to improving your outcome, so if in doubt, get your spot checked out by a board-certified dermatologist.

May marks Skin Cancer Awareness Month. With approximately 3.5 million skin cancers diagnosed in the U.S. each year, it's important to stay vigilant. Melanoma alone is expected to account for 144,860 diagnoses in 2018. There are more cases of skin cancer than breast, colon, lung, and prostate cancers combined.

Understanding Melanoma and Its Risks

Melanoma is the most serious form of skin cancer, capable of being life-threatening. However, the good news is that early diagnosis often leads to complete cures. Surprisingly, melanoma is the most common cancer for young adults aged 25-29. Around 75% of skin cancer deaths are attributed to melanoma. Of the three most common skin cancers, melanoma is the one most likely to be fatal.

Recent advances in treatment have led to cures even in patients with metastatic melanoma, or melanoma that has spread to other parts of the body. Many melanomas develop de novo (from a new spot), but some may arise from pre-existing moles. This makes regular self-checks essential to identify new or changing spots.

Other Common Types of Skin Cancer

In addition to melanoma, there are two other main types of skin cancer: basal cell carcinoma (BCC) and squamous cell carcinoma (SCC).

Basal Cell Carcinoma (BCC)

BCC often appears as a non-healing sore or crusted bump. It can also look like a red patch, sometimes misdiagnosed as dry skin or eczema. Fortunately, BCC is less likely to spread, and treatment typically involves minor in-office surgical procedures.

Squamous Cell Carcinoma (SCC)

SCC can appear as firm, red nodules or flat lesions with a scaly surface. Like BCC, it usually occurs in areas exposed to the sun, but it carries a higher risk of spreading if left untreated. Early diagnosis and treatment are key to avoiding complications.

Prevention and Early Detection: Key to Skin Cancer Survival

Most skin cancers have a genetic component, but excessive sun and UV exposure—especially from tanning beds—is a major contributing factor. Preventing skin cancer requires:

  • Avoiding peak sun hours (10 AM to 2 PM).
  • Applying and reapplying broad-spectrum sunscreen regularly.
  • Skipping tanning beds (spray tans are a safer option).
  • Getting an annual full-body skin check from a board-certified dermatologist.

Additionally, I recommend checking your skin once a month to monitor any changes in moles or spots.

The Importance of Skin Checks

Regular skin checks are easy, quick, and essential. Compared to other screenings, like colonoscopies, a skin check is much less invasive. Catching skin cancer early is crucial for successful treatment and long-term health.
