Laser treatment for fair skin
Abnormal cells are shown in the epidermis (outer layer of the skin). In stage haarband 0, abnormal cells are found in the squamous cell or basal cell layer of the epidermis (topmost layer of the skin). These abnormal cells may become cancer and spread into nearby normal tissue. Stage 0 is also called carcinoma in situ. The size of a tumor may be compared to the size of a pea (1 cm peanut (2 cm grape (3 cm walnut (4 cm lime (5 cm egg (6 cm peach (7 cm or grapefruit (10 cm). Stage i enlarge Stage i nonmelanoma skin cancer. In stage i, cancer has formed. The tumor is not larger than 2 centimeters at its widest point and may have one high-risk feature. Stage ii enlarge Stage ii nonmelanoma skin cancer. In stage ii, the tumor is either: larger than 2 centimeters at its widest point; or any size and has two or more high-risk features. Stage iii in stage iii : The tumor has spread to the jaw, eye socket, or side of the skull. Cancer may have spread to one lymph node on the same side of the body as the tumor. The lymph node is not larger than 3 centimeters. Enlarge Stage iii nonmelanoma skin cancer (1).

Many cancer deaths are caused when cancer moves from the original tumor and spreads to other tissues and organs. This is called metastatic cancer. This animation shows how cancer cells travel from the place in the body where they first formed to other parts of the body. Staging for nonmelanoma skin cancer that is on the eyelid is different from staging for nonmelanoma skin cancer that affects other parts of the body. A sharp pencil point is about 1 mm, a new crayon point is about 2 mm, and a new pencil eraser is about. The following are high-risk features for nonmelanoma skin cancer that is not on the eyelid: The tumor is thicker than 2 millimeters. The tumor is described as Clark level zonder iv (has spread into the lower layer of the dermis ) or Clark level V (has spread into the layer of fat below the skin). The tumor has grown and spread along nerve pathways. The tumor began on an ear or on a lip that has hair. The tumor has cells that look very different from normal cells under a microscope. The following stages are used for nonmelanoma skin cancer that is not on the eyelid: Stage 0 (Carcinoma in Situ) Enlarge Stage 0 nonmelanoma skin carcinoma in situ.
spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began (the primary tumor ) and travel through the lymph system or blood. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor ( metastatic tumor) in another part of the body. The cancer gets into the blood, travels through the blood vessels, and forms a tumor (metastatic tumor) in another part of the body. The metastatic tumor is the same type of cancer as the primary tumor. For example, if skin cancer spreads to the lung, the cancer cells in the lung are actually skin cancer cells. The disease is metastatic skin cancer, not lung cancer.

It is important to know the stage in order to plan treatment. The following tests and procedures may be used in the staging process: ct scan (cat scan) : A procedure that makes a series of detailed pictures of areas inside the body, taken from different angles. The pictures are made by a computer linked to an x-ray machine. A dye may be injected into a vein or swallowed to help the organs or tissues show up more clearly. This procedure is also called computed tomography, computerized tomography, or computerized axial tomography. Mri (magnetic resonance imaging) : A procedure that uses a magnet, radio waves, and a computer to make a series of detailed pictures of areas inside the body. This procedure is also called nuclear magnetic resonance imaging (nmri). Lymph node biopsy : For squamous cell carcinoma, the lymph nodes may be removed and checked to see if cancer has spread to them. Cancer can spread through tissue, the lymph system, anti and the blood : Tissue. The cancer spreads from where it began by growing into nearby areas. The cancer spreads from where it began by getting into the lymph system.
There are three ways that cancer spreads in the body. Cancer may spread from where it began to other parts of the body. Staging of nonmelanoma skin cancer depends on whether the tumor has certain "high-risk" features and if the tumor is on the eyelid. The following stages are used for nonmelanoma skin cancer that is not on the eyelid: Stage 0 (Carcinoma in Situ) Stage i stage i nonmelanoma skin cancer. The tumor is no more than 2 centimeters. Stage ii stage ii nonmelanoma skin cancer. The tumor is more than 2 centimeters wide. Stage iii stage iv the following stages are used for nonmelanoma skin cancer on the eyelid: Stage 0 (Carcinoma in Situ) Stage i stage ii stage iii stage iv treatment is based on the type of nonmelanoma skin cancer or other skin condition diagnosed: Basal. The process used to find out if cancer has spread within the skin or to other parts of the body is called staging. The information gathered from the staging process determines the stage of the disease.
A small sample of tissue is removed to be checked under a microscope. Skin thickness is different on different parts of the body. Incisional biopsy : A scalpel is used to remove part of a growth. Excisional biopsy : A scalpel is used to remove the entire growth. The prognosis (chance of recovery ) depends mostly on the stage of the cancer and the type of treatment used to remove the cancer. Treatment options depend on the following: The stage of the cancer (whether it has spread deeper into the skin or to other places in the body). The type of cancer. The size of the tumor and what part of the body it affects. The patients general health. Stages of skin Cancer key points After nonmelanoma skin cancer has been diagnosed, tests are done to find out if cancer cells have spread within the skin or to other parts of the body.
Laser skin Whitening AdvantagesFirm and look like a scar, and may be white, yellow, or waxy. Raised, and red or reddish-brown. Scaly, bleeding or crusty. Signs of actinic keratosis manicure include the following: A rough, red, pink, or brown, raised, scaly patch on the skin that may be flat or raised. Cracking or peeling of the lower lip that is not helped by lip balm or petroleum jelly. The following procedures may be used: skin exam : A doctor or nurse checks the skin for bumps or spots that look abnormal in color, size, shape, or texture. Skin biopsy : All or part of the abnormal-looking growth is cut from the skin and viewed under a microscope by a pathologist to check for signs of cancer. There are four main types of skin biopsies: Shave biopsy : A sterile razor blade is used to shave-off the abnormal-looking growth. Punch biopsy : A special instrument called a punch or a trephine is used to remove a circle of tissue from the abnormal-looking growth. A hollow, circular scalpel is used to cut into a lesion on the skin. The instrument is turned clockwise and counterclockwise to cut down about 4 millimeters (mm) to the layer of fatty tissue below the dermis.
Past treatment with radiation. Having a weakened immune system. Having certain changes in the genes that are linked to skin cancer. Being exposed to arsenic. Risk factors for actinic lubriderm keratosis include the following: being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. Although having a fair complexion is a risk factor for skin cancer and actinic keratosis, botulinum people of all skin colors can get skin cancer and actinic keratosis. Not all changes in the skin are a sign of nonmelanoma skin cancer or actinic keratosis. Check with your doctor if you notice any changes in your skin. Signs of nonmelanoma skin cancer include the following: A sore that does not heal. Areas of the skin that are: raised, smooth, shiny, and look pearly.

It is more likely to invade nearby tissues and spread to other parts of the body. Actinic keratosis is a skin condition that sometimes becomes squamous cell carcinoma. This summary is about nonmelanoma skin cancer and actinic keratosis. See the following pdq summaries for information on melanoma and other kinds of cancer that affect the skin: skin color and being exposed to sunlight can increase the risk of nonmelanoma skin cancer and actinic keratosis. Anything that increases your chance of getting a disease is called a risk factor. Having a risk factor does not mean that you will get cancer; not having risk factors doesnt mean that you will not get cancer. Talk with your doctor if you think you may be at risk. Risk factors for basal cell carcinoma and squamous cell carcinoma include the following: being exposed to natural sunlight or artificial sunlight (such as from tanning beds) over long periods of time. Having a fair complexion, which includes the following: fair skin that freckles and burns easily, does not tan, or tans poorly. Blue or green or other light-colored eyes. Red or blond hair.
The skin has several layers, but the two main layers are the epidermis (upper or outer layer) and reviews the dermis (lower or inner layer). Skin cancer begins in the epidermis, which is made up of three kinds of cells : Squamous cells : Thin, flat cells that form the top layer of the epidermis. Basal cells : round cells under the squamous cells. Melanocytes : Cells that make melanin and are found in the lower part of the epidermis. Melanin is the pigment that gives skin its natural color. When skin is exposed to the sun, melanocytes make more pigment and cause the skin to darken. Enlarge, anatomy of the skin showing the epidermis (including the squamous cell and basal cell layers dermis, subcutaneous tissue, and other parts of the skin. Skin cancer can occur anywhere on the body, but it is most common in skin that is often exposed to sunlight, such as the face, neck, hands, and arms. The most common types are basal cell carcinoma and squamous cell carcinoma, which are nonmelanoma skin cancers. Nonmelanoma skin cancers rarely spread to other parts of the body. Melanoma is a much rarer type of skin cancer.

General Information About skin Cancer, go to health Professional Version, key points. Skin cancer is a disease in which malignant (cancer) cells form in the tissues of the skin. There are different types of cancer that start in the skin. Skin color and being exposed to sunlight can increase the risk of nonmelanoma skin cancer and actinic keratosis. Nonmelanoma skin cancer and actinic keratosis often review appear as a change in the skin. Tests or procedures that examine the skin are used to detect (find) and diagnose nonmelanoma skin cancer and actinic keratosis. Certain factors affect prognosis (chance of recovery) and treatment options. The skin is the bodys largest organ. It protects against heat, sunlight, injury, and infection. Skin also helps control body temperature and stores water, fat, and vitamin.
