Introduction:
The skin is an organ that protects the body against the harmful effects of sunlight, infection, and injury and helps regulate body temperature and moisture. Skin cancer is the uncontrolled growth of skin cells, forming a tumorous mass. It can be either benign (where the tumor can grow but not spread to other organs) or malignant (which can spread to other organs). If detected early, it can be treated quickly with less scarring.
Skin cancer is the most common type of cancer in the United States. More than five million cases are diagnosed each year. Anyone can develop skin cancer. Certain factors, such as a family history of skin cancer and exposure to ultraviolet radiation from the sun, can increase the risk of cancer. Prevention is key when it comes to skin cancer. This can be achieved by using sunscreen and avoiding excessive exposure to ultraviolet radiation. Regular skin checks can help in the detection of any skin changes that may indicate skin cancer. The article discusses essential facts about skin cancer, including the different types of skin cancer, its risk factors, causes, symptoms, diagnosis, and prevention.
What Are the Types of Skin Cancer?
Three main types of skin cancer are as follows:
-
Basal Cell Carcinoma: It is the most common type of skin cancer. It appears as a raised, pink, scaly patch on the skin. Basal cell carcinoma grows slowly and rarely spreads to other body parts.
-
Squamous Cell Carcinoma: It is the second most common type of skin cancer that appears as a raised, red, scaly patch on the skin. If left untreated, it can spread to other body parts.
-
Melanoma: It is the least common and deadliest type of skin cancer. Melanoma appears as a dark brown or black mole with irregular borders. It can spread quickly to other body parts.
What Are the General Facts About Skin Cancer?
Skin cancer is the most common cancer worldwide, with millions of cases diagnosed each year. The three common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. In these, melanoma is a less common and more aggressive form. Exposure to ultraviolet radiation from the sun or tanning beds is a major risk factor for developing skin cancer. Protecting the skin from UV exposure is crucial for prevention. If skin cancer is detected and treated early, the prognosis is good. However, advanced or metastatic skin cancer is more challenging to treat and may have a poor prognosis. Many individuals diagnosed with skin cancer go on to lead healthy and fulfilling lives after treatment. Regular follow-up care and sun protection practices are important for long-term survivorship.
What Are the Skin Cancer Survival Rates and Mortality Rates?
The survival rate of skin cancer is more than 95 percent. The survival rate of melanoma is around 99 percent if an individual gets proper treatment before it spreads to surrounding lymph nodes. The survival rate is 65 percent if melanoma is treated and spread to adjacent lymph nodes. The survival rate is 30 percent if melanoma affects lymph nodes and organs.
The mortality or death rate of persons affected with melanoma is higher compared to basal cell carcinoma and squamous cell carcinoma. The mortality rate is high among older adults and men. Older adults may have a high risk of developing an aggressive form of melanoma. Men are more likely to be diagnosed with advanced-stage melanoma as compared to women.
What Are the Causes of Skin Cancer?
The causes of skin cancer are as follows:
-
Long-term sun exposure.
-
Episodes of severe sunburn at a very early age.
-
Repeated exposure to radiation.
-
Unusual scars on the skin.
-
Weakened immune system.
-
Frequent exposure to certain chemicals.
-
Tanning beds.
What Are the Risk Factors of Skin Cancer?
Several factors can increase an individual risk of developing skin cancer, including:
-
Exposure to UV (ultraviolet) radiation.
-
Being fair-skinned.
-
Certain skin conditions.
-
A family history of skin cancer.
-
Elderly population.
-
Having many moles in the body, especially dysplastic nevi.
-
History of sunburns.
What Are the Signs and Symptoms of Skin Cancer?
Depending on the type of skin cancer, the appearance can vary greatly. Look out for the following warning signs.
-
A non-healing sore that started as a patch or rash.
-
A growth that itches, bleeds easily, and crusts over.
-
Change in shape and size of existing marks or discolorations.
-
Formation of ulcers, rough and scaly areas that may bleed or ooze.
-
Lesions that are painful, tender, or itchy.
-
Red, translucent bumps that are shiny and pearly.
-
A raised area with a central lump.
How Can Skin Cancer Be Diagnosed?
In case a physician spots a suspicious-looking sore on the skin, then a dermatologist can make a diagnosis based on its characteristic appearance alone. Skin cancer diagnosis involves a combination of a physical examination and various tests. The diagnostic tests are as follows:
-
Skin Examination: A healthcare professional will examine the skin and look for any suspicious moles or other skin growths.
-
Imaging Tests: The tests include magnetic resonance imaging (MRI), computed tomography (CT) scans, and X-rays are used to determine if cancer has spread beyond the skin.
-
Blood Tests: The doctor may prescribe a blood test to check for markers that indicate the presence of basal cell carcinoma, squamous cell carcinoma, and melanoma.
-
Biopsy: The doctor may prescribe a biopsy in case of any suspicious mole or growth. The biopsy procedure involves removing a small skin sample for laboratory testing. If cancer has spread to nearby lymph nodes, the doctor may suggest a sentinel lymph node biopsy to diagnose the condition.
How Can Skin Cancer Be Treated?
The treatment of skin cancer depends on various factors such as size, stage, location, and a person's overall health. The treatment measures are as follows:
-
Surgery: The most common method of treating skin cancer is surgery. Surgery involves removing the cancerous cells from the skin by techniques such as excisional biopsy and curettage.
-
Radiation Therapy: It involves using high-energy X-rays or other types of radiation to destroy cancer cells. The healthcare provider may recommend it for people who cannot have surgery or who have a high risk of recurrence.
-
Medications: The healthcare provider may prescribe topical medications such as Imiquimod and Fluorouracil to treat certain types of cancer. Other medications include chemotherapy and immunotherapy drugs to treat advanced cases of cancer.
How Can Skin Cancer Be Prevented?
There are several ways to prevent skin cancer are as follows:
-
Protecting Skin From the Sun: The most important way to prevent skin cancer is to protect the skin from harmful UV radiation. This can be done by wearing protective clothing and using sunscreen lotion with an SPF (sun protection factor).
-
Avoiding Tanning Beds: These emit UV radiation, which can increase the risk of developing cancer.
-
Checking Skin Regularly: Regularly checking the skin for any changes in existing moles can help detect early skin cancer.
-
Avoiding Exposure to UV Radiation: Avoid unnecessary exposure to UV radiation, such as from sun lamps.
Conclusion
Skin cancer is the most common type of cancer in the world. It is caused due to abnormal growth of skin cells or exposure to ultraviolet radiation from the sun or other sources. The three main types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Prevention is the main key to reducing skin cancer. It can be done by protecting the skin from harmful radiations from the sun, avoiding tanning beds, quitting smoking, and checking the skin regularly. Early detection and treatment may prevent the further spread of skin cancer. Wearing protective clothing such as full-sleeved clothes helps in reducing the risk of skin cancer.
