Skin cancer can go untreated for a long period of time depending on the type and severity of the cancer. Melanoma, the most serious type of skin cancer, can grow and spread quickly if left untreated. Other types of skin cancer, such as basal cell carcinoma and squamous cell carcinoma, can also progress if not treated.
Types of Skin Cancer
There are three main types of skin cancer: melanoma, basal cell carcinoma, and squamous cell carcinoma.
Melanoma is the most serious type of skin cancer, and it develops from the cells that produce melanin, which is the pigment that gives skin its color. Melanoma can spread quickly and become hard to treat if left untreated.
Basal cell carcinoma is the most common type of skin cancer. This type of cancer usually develops in areas of the skin exposed to the sun, such as the head, neck, and hands. Basal cell carcinoma usually grows slowly, but it can cause disfigurement if not treated.
Squamous cell carcinoma is another type of skin cancer. It often develops in areas of the skin exposed to the sun, such as the face, ears, and neck. Squamous cell carcinoma can also spread to other parts of the body if left untreated.
Signs and Symptoms of Skin Cancer
The signs and symptoms of skin cancer can vary depending on the type. Common signs and symptoms include changes in the size, shape, or color of a mole, an open sore that doesn't heal, a scaly patch of skin, or an area of the skin that is swollen or tender.
Diagnosis of Skin Cancer
If you have any of the signs or symptoms of skin cancer, it's important to see a doctor for a diagnosis. The doctor will likely perform a physical exam and may take a biopsy of the suspicious area. The biopsy will be examined under a microscope to determine if it is cancerous.
Treatment of Skin Cancer
Treatment for skin cancer depends on the type and stage of the cancer. Treatment options may include surgery, radiation, chemotherapy, or a combination of treatments. It is important to get treatment as soon as possible to prevent the cancer from spreading.
