Skin cancer is the most common type of cancer globally, and unfortunately, its incidence is rising steadily. Melanoma, one of the deadliest forms of skin cancer, has seen an estimated 30% increase in the past decade alone.

Timely detection of skin cancer is critical, as it can make a huge difference in the effectiveness of treatment. Unfortunately, not everyone knows what signs to look for when it comes to skin cancer. In this article, we’ll explore the five types of skin cancer and provide a photo guide to help you spot suspicious-looking moles and lesions.

Basal cell carcinoma

Basal cell carcinoma (BCC) is the most common type of skin cancer and accounts for about 80% of all skin cancers. It usually occurs in areas of the skin that are exposed to the sun, such as the head, neck, or face.

BCC starts as a small, waxy bump that may bleed easily after a minor injury. Over time, the bump may get bigger, may ooze, and may develop into an open sore that doesn’t heal.

Squamous cell carcinoma

Squamous cell carcinoma (SCC) is the second most common type of skin cancer, occurring in about 20% of all cases. SCC typically appears as a red, scaly patch or bump on the skin that may bleed or become crusted.

It is also found in areas of the skin that are frequently exposed to the sun, such as the scalp, ears, face, and hands.

Melanoma

Unlike BCC and SCC, melanoma is a more aggressive type of skin cancer that can appear anywhere on the body, including areas that are not exposed to the sun. It usually starts as a mole or a dark spot on the skin that changes in size, shape, or color.

The ABCDE rule can help you remember what to look for when examining your skin for melanoma:.

Asymmetry: one half of the mole doesn’t match the other half
Border: the edges of the mole are irregular or blurred
Color: the color of the mole is not uniform and may include shades of brown, black, or red
Diameter: the mole is larger than 6 mm in diameter
Evolving: the mole changes in shape, size, or color over time

Kaposi sarcoma

Kaposi sarcoma is a rare type of skin cancer that usually affects people with weakened immune systems, such as those living with HIV/AIDS.

It appears as red or purple patches or lesions on the skin, often on the legs or face, and can also affect the internal organs, such as the lungs or digestive tract. Kaposi sarcoma is caused by a virus called human herpesvirus 8 (HHV-8) and is not related to sun exposure.

Merkel cell carcinoma

Merkel cell carcinoma is a rare and aggressive form of skin cancer that typically appears as a firm, painless, and fast-growing nodule on the skin. It is most common in older people and those with weakened immune systems.

Merkel cell carcinoma can spread quickly to other parts of the body, so early detection is essential for effective treatment.

Conclusion

It’s crucial to consult a dermatologist if you notice any changes in your skin, such as suspicious-looking moles, patches, or lesions.

Early detection can help improve the chances of successful treatment and prevent skin cancer from spreading to other parts of the body. Remember to protect your skin from harmful UV rays by wearing sunscreen, protective clothing, and avoiding sun exposure during peak hours.
