Melanoma Skin

Melanoma Skin



Melanoma skin


     Melanoma skin is the most common type of cancer.

     People with lighter skin, who burn easily, presents an increased risk for developing skin cancer.

     Other less important factors involved in the occurrence of this cancer are the medical or industrial exposure to X-rays, scars from burns or released various diseases and occupational exposure to coal and arsenic compounds and finally a family history.

     Actinic keratosis - the early stage of melanoma skin

     Actinic or solar keratoses are considered the early stage in skin cancer. They are small spots with scales, often located on face, ears, neck, forearms and back of hands from those with light skin and long photo exposure. Actinic keratoses can be treated by cryotherapy (freezing), topical chemotherapy (application of medicines under form of creams, lotions), chemical peeling, dermabrasion, laser surgery, curettage, photodynamic therapy (a compound chemical is applied to the skin before photo exposure) or other surgical skin procedures. Some actinic keratoses can progress to more advanced stages that require extensive treatment. The use of sunscreens can help prevent keratoses even after extensive actinic sunburn.


Basal cell carcinoma (BCC)


     Basal cell carcinoma is the most common type of melanoma skin and appears frequently on the head, neck and hands as a small nodule, red, or as a red stain; other body parts can also be affected. Basal cell carcinoma meets frequently in those with openly photo type and frequently in those with dark skin. It does not extend quickly. It takes months or years for a lesion to grow a half inch in diameter. Untreated, the basal cell carcinoma will start to bleed, to make crusts, to heal, and then the cycle repeats. Although this type of cancer rarely metastasizes (not spreading in the body) it can expand under the skin to bones and nerves, causing local destruction.




Squamous cell carcinoma (SCC)


     Squamous cell carcinoma is the second as incidence and is frequently met in people with light skin and rarely in those with dark skin. Typically located at face level, lips and mouth, this type of melanoma skin may appear as a bulge or stain red. Squamous cell carcinoma can develop into a solid formation and become invasive. Unlike of basal cell carcinoma, this cancer can metastasize (can stretch to other body parts); as a result it requires early treatment.

     When detected early and treated properly, the cure rate for basal cell carcinoma, but also for the squamous cell is over 95%.


The evolution of melanoma skin:


     Melanoma skin usually develops slowly, invading and destroying adjacent tissue. It may take months or even more than a year until the appearance of the first signs. Basal cell carcinoma can invade normal skin and can change its appearance, can destroy deep tissues, as muscles and bones. This type of skin cancer very rarely metastasizes. More dangerous is, however, squamous cell carcinoma, which develops slowly and frequently metastasize. The disease can even lead to disfigurement of the patient. It is more invasive than basal cell and can affect the scalp, ears, eyelids, nose, lips or other body parts. Of cancer cells, 2-6% invades other organs of the body.


Symptoms of melanoma skin:


     Basal cell cancer symptoms can be varied and may include changes in appearance such as skin lesions pearl farms in appearance, with blood vessels that have an appearance of cloth spider, sensitive and red spots that easily bleeds, small, shiny lesions which may resemble warts or moles, scars similar spots, especially on the face, bleeding lesions, forming scabs and bleeding and that does not heal within three weeks. Moles are suspicious when they change their shape, size or color. Signs of squamous cell carcinoma occurred on the face, neck or your head.

     Another signs of this disease include persistent lesions, firm, red skin on areas exposed to sun, skin areas that have a strong point (scaled), bleeding or develop a crust. These wounds may increase in size over a period of several months. In this type of melanoma skin, skin growths appearing as a wart and wounds which does not heal, but also thin skin areas at the lower lip, especially in smokers or individuals who exhibit frequently towards the sun or wind.
