Skin cancer is the most common type of cancer that affects millions of people worldwide. It occurs when there is an abnormal growth of skin cells, usually caused by excessive exposure to the harmful ultraviolet (UV) rays of the sun.
Recognizing the early signs of skin cancer is crucial for early detection and successful treatment. In this picture guide, we will discuss the various types of skin cancer and provide visual cues to help you identify the early signs.
1. Basal Cell Carcinoma (BCC)
Basal cell carcinoma is the most common type of skin cancer, accounting for about 80% of cases. It usually appears on sun-exposed areas such as the face and neck. The early signs of BCC include:.
– A pearly or waxy bump.
– Pink or red patches of skin.
– A sore that does not heal.
2. Squamous Cell Carcinoma (SCC)
SCC is the second most common type of skin cancer. It often develops on areas exposed to the sun, including the face, ears, and hands. The early signs of SCC include:.
– A scaly patch of skin with a crust or ulcer.
– A firm red nodule.
– A sore that does not heal.
3. Melanoma
Melanoma is the most deadly form of skin cancer. It can develop anywhere on the body, including areas not exposed to the sun. The early signs of melanoma can be remembered using the ABCDE rule:.
– Asymmetry: One half of the mole or lesion does not match the other half..
– Border: The edges are irregular, scalloped, or poorly defined..
– Color: The color is uneven, with shades of black, brown, tan, white, red, or blue..
– Diameter: The size is larger than 6 millimeters, although melanomas can sometimes be smaller..
– Evolving: The mole or lesion is changing in size, shape, or color..
4. Actinic Keratosis
Actinic keratosis is a precancerous condition that can develop into SCC if left untreated. These rough, scaly patches usually occur on sun-exposed areas such as the face, lips, ears, scalp, and forearms. The early signs of actinic keratosis include:.
– Rough, dry, or scaly patches of skin.
– Red or pink patches.
– Itching or burning sensation.
5. Merkel Cell Carcinoma (MCC)
Merkel cell carcinoma is a rare but aggressive type of skin cancer. It appears as a firm, shiny nodule on the face, neck, or head. The early signs of MCC include:.
– A firm, painless bump.
– Red, purple, or pink patch.
– Swelling or bruising around the lesion.
6. Kaposi Sarcoma (KS)
Kaposi sarcoma is a type of skin cancer that develops from the cells lining the lymph or blood vessels. It often appears as purple or red lesions on the skin or mucous membranes. The early signs of KS include:.
– Discolored patches or plaques.
– Lesions that may be flat or raised.
– Swelling and discomfort in the affected area.
7. Sebaceous Carcinoma
Sebaceous carcinoma is a rare and aggressive skin cancer that usually arises from the oil glands in the skin. It commonly affects the eyelids, but can also occur in other areas. The early signs of sebaceous carcinoma include:.
– A painless, growing nodule.
– A yellow, waxy lump.
– Thickening of the affected skin.
8. Dermatofibrosarcoma Protuberans (DFSP)
DFSP is a rare type of skin cancer that arises in the deep layers of the skin. It often appears as a firm, raised, red or purplish lump. The early signs of DFSP include:.
– A red or bluish lump that does not go away.
– A small, flat area that is reddish or purplish.
– Thickening or puckering of the skin.
9. Angiosarcoma
Angiosarcoma is a rare and aggressive form of skin cancer that develops in the blood vessels or lymphatic vessels. It often appears as a bruise-like lesion that grows rapidly. The early signs of angiosarcoma include:.
– A bruise-like patch of skin that does not heal.
– An enlarging, reddish or purplish lump.
– Bleeding or ulceration.
10. Cutaneous Lymphoma
Cutaneous lymphoma is a type of skin cancer that arises from the white blood cells called lymphocytes. It can appear as various types, including mycosis fungoides and Sézary syndrome. The early signs of cutaneous lymphoma include:.
