Skin Cancer Symptoms, Signs, Types, and Treatment. What is skin cancer Skin cancer is a common and locally destructive cancerous malignant growth of the skin.

It will be expensive. It originates from the cells that line up along the membrane that separates the superficial layer of skin from the deeper layers. Unlike cutaneous malignant melanoma, the vast majority of these sorts of skin cancers have a limited potential to spread to other parts of the body metastasize and become life threatening. There are three major types of skin cancer 1 basal cell carcinoma the most common and 2 squamous cell carcinoma the second most common, which originate from skin cells, and 3 melanoma, which originates from the pigment producing skin cells melanocytes but is less common, though more dangerous, than the first two varieties. What are the risk factors for skin cancerThe most common risk factors for skin cancer are as follows. Ultraviolet light exposure, either from the sun or from tanning beds. Fair skinned individuals, with hazel or blue eyes, and people with blond or red hair are particularly vulnerable. The problem is worse in areas of high elevation or near the equator where sunlight exposure is more intense. A chronically suppressed immune system immunosuppression from underlying diseases such as HIVAIDS infection or cancer, or from some medications such as prednisone or chemotherapy. Exposure to ionizing radiation X rays or chemicals known to predispose to cancer such as arsenic. Certain types of sexually acquired wart virus infections.

Skin Cancer Symptoms and Signs. Basal Cell Carcinoma BCCBCC is the most common type of skin cancer and has a predilection for sun exposed skin. Tumors may appear as a pearly or waxy bumps usually with visible blood vessels nodular BCC, or as a flat scaly reddish patch superficial BCC with a brown border, or as a hard or scar like lesion sclerosing BCC. Frequently BCCs can be itchy, often bleed, or in more advanced cases, ulcerate. Is skin cancer hereditary Since most skin cancers are caused by ultraviolet light exposure, skin cancers are generally not considered to be inherited. But the fact that skin cancer is much more common among poorly pigmented individuals and that skin color is inherited does support the proposition that genetics are very important. There are some very rare genetic syndromes that result in an increased number of skin cancers in those affected. What causes skin cancer It appears basal cell skin cancers arise from DNA mutations in the basaloid cells in the upper layer of the skin. Many of these early cancers seem to be controlled by natural immune surveillance, which when compromised may permit the development of masses of malignant cells that begin to grow into tumors. In squamous cell cancers, the tumors arise from normal squamous cells in the higher layers of the skin of the epidermis. As with basal cell cancers, these cells are prevented from growing wildly by natural mutational repair mechanisms. When there is an alteration in these genes or the immune surveillance system that controls it, these skin cancers start to grow. In most instances, the genes are altered by ultraviolet exposure. What are the different types of skin cancer There are several different types of skin cancers Basal cell carcinoma is the most common cancer in humans. Over 1 million new cases of basal cell carcinoma are diagnosed in the U. S. each year. There are several different types of basal cell carcinoma, including the superficial type, the least worrisome variety the nodular type, the most common and the morpheaform, the most challenging to treat because the tumors often grow into the surrounding tissue infiltrate without a well defined border. Squamous cell carcinoma accounts for about 2. In most instances, its biologic behavior is much like basal cell carcinoma with a small but significant chance of distant spread. Less common skin cancers include melanoma, Merkel cell carcinoma, atypical fibroxanthoma, cutaneous lymphoma, and dermatofibrosarcoma. What are the signs and symptoms of skin cancer Most basal cell carcinomas have few if any symptoms. Squamous cell carcinomas may be painful. Both forms of skin cancer may appear as a sore that bleeds, oozes, crusts, or otherwise will not heal. They begin as a slowly growing bump on the skin that may bleed after minor trauma. Both kinds of skin cancers may have raised edges and a central ulceration. Signs and symptoms of basal cell carcinomas include Appearance of a shiny pink, red, pearly, or translucent bump. Pink skin growths or lesions with raised borders that are crusted in the center. Raised reddish patch of skin that may crust or itch, but is usually not painful. A white, yellow, or waxy area with a poorly defined border that may resemble a scar. Excel File Format Invalid more. Signs and symptoms of squamous cell carcinomas include Persistent, scaly red patches with irregular borders that may bleed easily. Open sore that does not go away for weeks. A raised growth with a rough surface that is indented in the middle. A wart like growth. Actinic keratoses AK, also called solar keratoses, are scaly, crusty lesions caused by damage from ultraviolet light, often in the facial area, scalp, and backs of the hands. These are considered precancers because if untreated, up to 1. When is a mole dangerous or high risk for becoming a skin cancerMoles are almost always harmless and only very rarely turn into skin cancer. If a mole becomes cancerous, it would be a melanoma. There is a precancerous stage, called a dysplastic nevus, which is somewhat more irregular than a normal mole. An early sign of melanoma is noticing a difference in a mole asymmetry, irregular border, color changes, increasing diameter, or other evolving changes may signify a mole is melanoma. Moles never become squamous cell carcinomas or basal cell carcinomas. What are the most common sites where skin cancer develops Skin cancers typically arise in areas of the skin exposed to the sun repeatedly over many years such as on the face and nose, ears, back of the neck, and the bald area of the scalp. Less commonly, these tumors may appear at sites with only limited sun exposure such as the back, chest, or the extremities. However, skin cancer may occur anywhere on the skin. How do physicians diagnose skin cancer A skin examination by a dermatologist is the way to get a definitive diagnosis of skin cancer. In many cases, the appearance alone is sufficient to make the diagnosis. A skin biopsy is usually used to confirm a suspicion of skin cancer. This is performed by numbing the area under the tumor with a local anesthetic such as lidocaine. A small portion of the tumor is sliced away and sent for examination by a pathologist, who looks at the tissue under a microscope and renders a diagnosis based on the characteristics of the tumor. What is the staging for skin cancer There is no specific staging system for basal cell carcinoma. If the tumor is wider than 2 cm about inch diameter, it is probably a more serious tumor.

There is a staging system for squamous cell carcinoma. Large tumors that are thicker than 2 mm, invade the nerve structures of the skin, occur on the ear, and have certain worrisome characteristics under the microscope are of more concern.
