MOST COMMON SKIN CANCER IN THE WORLD – 2022
What is skin cancer?
Skin cancer, which is an abnormal growth of skin cells, occurs most often in sun-exposed skin. However, this extremely common type of cancer can also occur in areas of the skin that are not normally exposed to sunlight.
There are three main types of skin cancer: basal cell carcinoma, squamous cell carcinoma, and melanoma.
You can reduce your risk of skin cancer by limiting or avoiding exposure to ultraviolet light (UV-infrared). Examining your skin for suspicious changes can help detect cancer at an early stage. Early detection of cancer gives you the highest chance of successful treatment.
What are the areas where skin cancer develops?
Skin cancer first occurs in areas of the skin exposed to the sun, including the scalp, face, lips, ears, neck, chest, arms and hands, and in women, the feet. However, it can also occur in areas that rarely see sunlight, such as the underside of the palms, fingernails and toenails, and the genital area.
Skin cancer can affect all people, regardless of skin color, including people with dark skin. While melanoma occurs in people with dark skin, it is more likely to be seen in areas that are not normally exposed to the sun, such as the inside of the hand and the sole of the foot.
What are the types of skin cancer?
Symptoms and signs of basal cell carcinoma:
Basal cell carcinoma usually occurs in areas of the body that are not exposed to the sun, such as the neck or face.
Basal cell carcinoma can be seen as follows:
- Pearl-like, pearl-like or candle-like watermelons
- Injury similar to a flat, flesh-colored or brown wound
Symptoms and signs of squamous cell carcinoma:
Squamous cell carcinoma most often occurs in sun-exposed areas of the body, such as the face, ears, and hands. In people with dark skin, squamous cell carcinoma is more likely to develop in areas of the skin that are less exposed to the sun.
Squamous cell carcinoma can be seen as follows:
- Solid, red nodule
- A flat spot with a crusty or patterned surface
Symptoms and signs of melanoma:
Melanoma can occur anywhere on your body, on the skin where no other symptoms are observed, or on a skin spot that has turned into cancer. Melanoma is most commonly seen on the face or body of men. In women, this type of cancer most often occurs in the legs. Melanoma can occur in both men and women on skin that has not been exposed to the sun.
Melanoma can be seen in all people, regardless of skin color. In people with dark skin, melanoma is more likely to occur on the inside of the hand or on the heel or under the fingernails and toenails.
Symptoms of melanoma include:
- A large brown spot with dark spots
- A skin spot that shows a change in color, size, or feel, or where bleeding is observed
- A small spot with irregular boundaries and visible areas of red, white, blue, or blue-black
- Dark spots on the inside of the hand, heel, fingertips, or toes, or on the mucous membranes surrounding the mouth, nose, vagina, or anus
Symptoms and signs of skin cancer with less frequent intervals:
Other types of skin cancers that are less common include:
Kaposi’s sarcoma. This rare type of skin cancer occurs in the blood vessels of the skin and causes red or purple patches on the skin or membranes of the bone tissue.
Kaposi’s sarcoma mainly occurs in people with weakened immune systems, such as those who take AIDS and organ transplants, as well as those who take drugs that suppress their immune system.
Other people at increased risk of Kaposi’s sarcoma include young men living in Africa or older men with Italian or Eastern European Jewish genes.
Merkel cell carcinoma. Merkel cell carcinoma causes hard, shiny nodules that form on the skin or just under the skin and at the hair follicles. Merkel cell carcinoma is most common in the head, neck and body.
Sebaceous gland carcinoma. This rare and aggressive cancer is caused by sebaceous glands in the skin. Carcinoma of the sebaceous gland, which usually appears as a solid, painless nodule, can occur anywhere, but most often occurs on the eyelid and is often confused with other eyelid problems.
