Skin cancer is the uncontrolled development of cancer cells in the skin. If left untreated, certain forms of skin cancer cells can migrate to other organs and tissues, including lymph nodes and bone. Skin cancer is the most common cancer in the United States, affecting one out of every five people at some time in their life, according to the Skin Cancer Foundation.
What is the role of your skin?
Your skin protects your body from things like water loss, bacteria, and other poisons by acting as a barrier. The two basic layers of the skin are the dermis (the deeper, thicker layer) and the epidermis (the outer layer) (the epidermis). Three types of cells make up the epidermis. The outermost layer is made up of squamous cells, which shed and turn over on a regular basis. The deepest layer is the basal layer, which is made up of basal cells. Finally, melanocytes are cells that make melanin, the pigment that gives your skin its color. More sun exposure causes these cells to produce more melanin, resulting in a tan. This is your body’s attempt to protect you from the sun, and it’s a sign that you’re being sunburned.
The epidermis is exposed to the elements all of the time. It can be harmed by the sun, disease, or cuts and scrapes, despite the fact that it loses skin cells on a regular basis. The remaining skin cells are constantly replicating and multiplying to replace the sloughed skin, and they can sometimes become unduly reproduced or multiplied, resulting in a benign or malignant skin tumor.
Some instances of common skin lumps are as follows:
Actinic keratosis (AK)
Actinic keratosis, also known as solar keratosis, appears as a red or pink rough patch of skin on sun-exposed areas of the body. Exposure to UV light in the sun causes them to develop. This is the most common type of precancer, and it can proceed to squamous cell carcinoma if left untreated.
Basal cell carcinoma (BCC)
The most common type of skin cancer is basal cell carcinoma, which accounts for over 90% of all skin cancer cases. Basal cell carcinoma is a slow-growing cancer that seldom spreads to other parts of the body. It is most common in the head and neck. A elevated, pearly or waxy pink hump with a dimple in the center emerges on the skin. Translucent skin can also be caused by blood vessels near the surface.
Squamous cell carcinoma (SCC)
Skin cancer that affects cells in the epidermis’ outer layer is known as squamous cell carcinoma. It is frequently more aggressive than basal cell carcinoma and can spread to other parts of the body if left untreated. On sun-exposed areas like the hands, head, neck, lips, and ears, it commonly appears as red, scaly, and rough skin lesions. Similar red spots could be caused by squamous cell carcinoma in situ (Bowen’s disease), the earliest form of squamous cell cancer.
Melanoma is far more dangerous than basal and squamous cell carcinomas, accounting for about three-quarters of all skin cancer-related deaths. Melanocytes, or pigment-producing skin cells, are affected. While most people have a mole, which is a benign collection of melanocytes, a melanoma can be suspected if the mole exhibits the following characteristics:
-The design is asymmetrical.
-unprecedented irregularities at the border
-a color that does not always match
-diameter greater than 6 millimeters
-modifications in size or form
There are four types of melanoma:
Superficial spreading melanoma: The most common type of melanoma, having lesions that are often flat, uneven in shape, and contain a variety of black and brown tints; it can appear at any age.
Melanoma lentigo maligna is a kind of melanoma that primarily affects the elderly and causes large, flat, brownish lesions.
Nodular melanoma is a kind of melanoma that appears as a raised patch and can be dark blue, black, or reddish-blue in color, although it can also be colorless.
The rarest type of lentiginous melanoma, it affects the palms, soles of the feet, or under the finger and toenail.
Kaposi sarcoma (Kaposi’s sarcoma)
Kaposi sarcoma is another type of cancer that causes brownish-red to blue skin lesions on the legs and feet, although it is not considered a skin cancer. It affects the cells that line the blood vessels that run close to the skin’s surface. This cancer is caused by a type of herpes virus, and it is particularly common in patients with weakened immune systems, such as those with AIDS.
Risk factors of skin cancer:
Skin cancers appear in a variety of shapes and sizes, but they all share the same risk factors:
-prolonged exposure to the sun’s ultraviolet (UV) radiation
-having turned 40 years old
-if your family has a history of skin cancer
-having a light skin
-having received an organ transplant
-Skin cancer can still strike young people and people with dark skin.
The earlier skin cancer is detected, the better the long-term prognosis. Make it a habit to check your skin on a frequent basis. Make an appointment with a dermatologist for a thorough check if you notice any anomalies. Discover how to conduct a skin self-examination. The best ways to protect yourself from all types of skin cancer are to use sunscreen and restrict your time in the sun.
Prevention of skin cancer:
The majority of skin cancers can be avoided. Follow these skin cancer prevention tips to stay safe:
In the middle of the day, stay out of the sun. The sun’s rays are greatest for many people in North America between 10 a.m. and 4 p.m. Even in the winter or when the sky is hazy, schedule outside activities for other times of the day.
UV radiation is absorbed all year, and clouds provide little protection from harmful rays. Sunburns and suntans cause skin damage and raise your chance of developing skin cancer, therefore avoiding the sun at its brightest helps you avoid them. Skin cancer can also be caused by long-term exposure to the sun.
Wear sunblock all year. Sunscreens do not block all dangerous UV light, particularly the UV that can cause melanoma. They do, however, play an important part in a comprehensive sun protection program.
Even on cloudy days, use a broad-spectrum sunscreen with an SPF of at least 30. Apply sunscreen liberally and reapply every two hours — or more frequently if you’re swimming or sweating heavily. Apply sunscreen liberally to all exposed skin, including your lips, the tips of your ears, the backs of your hands, and the backs of your neck.
