What skin cancer looks like? Who are at higher risk?

We all know that wearing sunscreen and protecting our skin from the sun is crucial, but do we really know what to look for when it comes to skin cancer? It can be easy to dismiss a new mole or a changing freckle, but early detection is key when it comes to treating skin cancer effectively. So, what exactly should we be looking for?

Skin cancer is the abnormal growth of skin cells, often triggered by excessive exposure to ultraviolet (UV) radiation from the sun or tanning beds. It's important to remember that skin cancer can affect anyone, regardless of skin tone. While those with fairer skin are statistically more susceptible, people of all ethnicities and backgrounds can develop this condition.

Knowing what to look for is the first step in taking control of your skin health. While this guide provides valuable information, it is not a substitute for professional medical advice. If you notice anything unusual on your skin, consult a dermatologist immediately. Early detection is key in successfully treating skin cancer.

There are several types of skin cancer, and they can appear in various forms. Let's break down some of the most common types and their visual cues:

Basal Cell Carcinoma: This is the most common type of skin cancer and often appears on areas frequently exposed to the sun, such as the face, ears, and neck. Keep an eye out for:

A pearly or waxy bump
A flat, flesh-colored or brown scar-like lesion
A bleeding or scabbing sore that heals and returns

Squamous Cell Carcinoma: This type of skin cancer also typically appears on sun-exposed areas, but it can develop anywhere on the body. Look for:

A firm, red nodule
A flat lesion with a scaly and crusted surface
A sore that doesn't heal or heals and returns
A raised growth with a central depression

Melanoma: This is the most serious type of skin cancer. While less common, it's crucial to catch it early. Melanoma can develop within existing moles or appear as a new, dark spot. Remember the "ABCDE" rule when checking moles:

Asymmetry: One half of the mole doesn't match the other
Border: The edges of the mole are irregular, blurred, or notched
Color: The mole has different shades of color, such as black, brown, tan, blue, red, or white
Diameter: The mole is larger than 6 millimeters across (about the size of a pencil eraser), though it can be smaller
Evolving: The mole is changing in size, shape, or color

Remember, this is just a starting point for understanding what skin cancer can look like. The best way to protect yourself is through regular self-exams, annual skin checks with a dermatologist, and consistent sun protection. Knowing your own skin and being aware of any changes is empowering and could ultimately save your life.
