Beyond the Surface: 7 Unexpected Areas Where Skin Cancer Can Develop

Skin Cancer on Surprising Sites: A Comprehensive Guide

As we all know, skin cancer is a prevalent and potentially deadly disease that affects millions of people around the world. While it’s commonly associated with sun exposure, skin cancer can actually occur on surprising sites that are often overlooked. In this comprehensive guide, we will explore the lesser-known locations where skin cancer can appear and what you can do to prevent and detect it.

What is Skin Cancer?

Before we delve into the surprising sites where skin cancer can occur, let’s first define what skin cancer is. Skin cancer is a type of cancer that develops in the skin cells, typically as a result of exposure to ultraviolet (UV) radiation from the sun or tanning beds. There are several types of skin cancer, including basal cell carcinoma, squamous cell carcinoma, and melanoma. While all types of skin cancer can be dangerous, melanoma is the most serious and potentially deadly.

Skin Cancer on Surprising Sites

While most people associate skin cancer with sun-exposed areas like the face, arms, and legs, skin cancer can actually occur on surprising sites that are often overlooked. Here are some of the surprising sites where skin cancer can appear:

  1. Scalp: The scalp is a common site for skin cancer, especially in people with thinning hair or balding. It can be challenging to detect skin cancer on the scalp, so it’s essential to have regular check-ups with a dermatologist.
  2. Lips: Skin cancer can occur on the lips, especially the lower lip. It can appear as a persistent sore that doesn’t heal or as a bump that bleeds easily.
  3. Fingernails and toenails: Skin cancer can develop under or around the nails, typically in people with dark skin. It can appear as a dark streak or a spot that doesn’t go away.
  4. Genital area: Skin cancer can occur on the genitals, including the penis, vulva, and anus. It can appear as a lump or sore that doesn’t heal.
  5. Feet: Skin cancer can occur on the soles of the feet, between the toes, and under the toenails. It can appear as a discolored patch or a sore that doesn’t heal.

Prevention and Detection

Now that you know the surprising sites where skin cancer can occur, let’s discuss how you can prevent and detect it. Here are some tips:

  1. Wear protective clothing: To prevent skin cancer, it’s essential to protect your skin from the sun’s harmful rays. Wear protective clothing like long-sleeved shirts, pants, and wide-brimmed hats.
  2. Use sunscreen: Use a broad-spectrum sunscreen with an SPF of at least 30 and reapply it every two hours, especially if you’re swimming or sweating.
  3. Avoid tanning beds: Tanning beds emit UV radiation, which can increase your risk of skin cancer. Avoid using them altogether.
  4. Conduct self-exams: Regularly check your skin for any changes, including new moles, growths, or spots that have changed in size, shape, or color.
  5. Visit a dermatologist: Schedule regular check-ups with a dermatologist, especially if you have a history of skin cancer or any concerning spots on your skin.


Skin cancer can occur on surprising sites that are often overlooked. By being aware of these sites and taking preventative measures, you can decrease your risk of developing skin cancer. Remember to wear protective clothing, use sunscreen, avoid tanning beds, conduct self-exams, and visit a dermatologist regularly. By taking these steps, you can help protect yourself from the potentially deadly effects of skin cancer.
