Skin Cancer: The Most Common Cancer Worldwide

Skin cancer is the most common type of cancer globally. According to the Skin Cancer Foundation, 1 in 5 Americans will develop a form of skin cancer by age 70.


This condition arises when abnormal cells grow uncontrollably in the skin, often beginning with changes in existing moles or the appearance of new growths. The three primary types of skin cancer are melanoma, basal cell carcinoma, and squamous cell carcinoma.


Early detection is vital for effective treatment and optimal outcomes. It’s crucial to schedule an annual total body skin examination with a dermatologist.

Skin cancer is categorized into two primary groups: non-melanoma and melanoma.

  • Non-Melanoma Skin Cancers:
  • Basal Cell Carcinoma: The most common type, often appearing as a pearly bump or a sore that doesn’t heal.
  • Squamous Cell Carcinoma: Typically manifests as a firm, red nodule or a flat lesion that may crust or bleed.
  • Melanoma: A more aggressive form of skin cancer that can develop from existing moles or appear as new, unusual growths.

Who Is at Risk for Skin Cancer?

Certain factors can increase the likelihood of developing skin cancer:

  • Individuals with lighter skin tones, especially those who:
  • Have red hair
  • Are blonde with blue eyes
  • Have pigment disorders
  • Have numerous freckles or moles
  • Reside in areas with intense sunlight
  • While skin cancer is more common in lighter-skinned individuals, those with darker skin can also be affected.
  • Demographics:
  • Before age 49, white women are more likely to develop melanoma.
  • After age 50, men are more likely to be diagnosed with the disease.


Skin cancer occurs when abnormal cells grow uncontrollably in the skin. While it most commonly develops in sun-exposed areas, it can also appear in parts of the skin that don’t receive sunlight. The three primary types are:


  • Basal Cell Carcinoma: The most common and least aggressive form, with a high cure rate.
  • Squamous Cell Carcinoma: Also common and generally well-treated.
  • Melanoma: Less common but more aggressive, requiring prompt attention.


The main risk factor is exposure to ultraviolet (UV) radiation from the sun or tanning beds. Additional risk factors include:


  • Fair skin or light hair
  • History of sunburns
  • Family history of skin cancer
  • Weakened immune system
  • Exposure to certain environmental toxins, like arsenic

Signs can vary by type, but common indicators include:


  • Changes in size, shape, color, or texture of moles or spots
  • Itching, tenderness, or bleeding in affected areas

If you notice any unusual changes, it's important to seek medical attention promptly.



Treatment options depend on the cancer type, size, and location, as well as the patient's overall health. Common approaches include:


  • Surgical removal of cancerous tissue
  • Radiation therapy
  • Chemotherapy or immunotherapy, in some cases

Early detection significantly improves treatment success, making regular skin checks essential.

Sunscreen should be applied daily, regardless of weather conditions. UV rays can penetrate clouds, causing skin damage. It's recommended to apply sunscreen at least 15-30 minutes before sun exposure and reapply every two hours.

A total body skin exam by a dermatologist is vital for several reasons:


  • Early Detection: It helps identify skin cancers early, particularly melanoma, which is more treatable in its initial stages.
  • Diagnosis of Other Conditions: Dermatologists can diagnose various skin issues, such as dermatitis or psoriasis, allowing for timely treatment.
  • Skin Health Guidance: These exams provide a chance to discuss skin health, sun protection strategies, and skincare routines.

Regular exams are especially important for those with risk factors, such as a family history of skin cancer or fair skin. Overall, a total body skin exam is a proactive step in maintaining skin health and preventing skin-related issues.
