Learn about the different types of skin cancer, as well as how you can prevent them. Skin cancers are caused by mutations in skin cells’ DNA, which can lead to uncontrollable growth and the formation of a mass of cancer cells. Although the exact cause of skin cancer is not known, some risk factors are considered to be associated with a greater risk. Exposure to UV rays, excessive exposure to the sun, and certain genetic changes may increase the risk of developing some types of skin cancer.
Treatment for skin cancer depends on the stage, type, and location of the cancer. Surgical excision is the most common form of treatment, but some patients may opt for chemotherapy or radiation therapy. Other treatments include ointments, cryotherapy, curettage, and cautery. The recommended treatment for skin cancers depends on the type and stage of the disease and other risk factors, such as sunlight exposure. To protect yourself from the sun, wear wide-brimmed hats and use sunscreen with an SPF of at least 30.
The second most common type of skin cancer is squamous cell carcinoma. Squamous cells make up most of the epidermis. While melanoma is rare, it can spread and invade other parts of the body. Merkel cell cancer is more common in white people and men. This type of skin cancer is highly treatable if caught in its early stages. In the U.S., there are estimated to be approximately 1,500 cases of Merkel cell skin cancer each year. However, melanoma is the most dangerous type of skin cancer and only accounts for about 1% of all cases.
The two most common types of skin cancer are basal cell and squamous cell. Both types start in the epidermis, and they are commonly related to exposure to the sun. Melanoma, on the other hand, develops in melanocytes, the cells that produce the pigment melanin. If left untreated, melanoma can invade other areas of the body, including bones and tissue.
If you suspect you have a skin condition, make an appointment with your doctor immediately. A doctor can examine the area and refer you to a skin cancer specialist if necessary. He or she will examine the affected area closely for any dry patches, scaling, or bleeding. In some cases, your doctor may suggest a biopsy. This is a simple procedure that involves the removal of a suspicious patch of skin and sending it to a lab for testing.
After the diagnosis of a melanoma, a skin biopsy is performed. A doctor will remove a portion of your skin and any suspicious lymph nodes. A dermatopathologist will review the pathological sample to determine the stage of the cancer. If the cancer spreads to lymph nodes, it is considered to be in the stage IV category.
