Information about Skin Cancer

There are several types of skin cancer that involve the growth of new moles or changes in moles, so moles and skin cancer are actually linked together. Skin cancer is one of the most common of all forms of cancers that humans can develop, and more than a million people are diagnosed with certain types of skin cancers every year. What cancer involves is a transformation by normal cells where they multiply and grow beyond their normal controls, forming a mass known as a tumor which is most commonly known as a lesion when it relates to skin cancer tumors.

The relationship between moles and skin cancer most commonly exists in bodies that have malignant melanoma, which is an extremely invasive and aggressive form of cancer. Malignant tumors are tumors that invade and encroach upon neighboring tissues as they grow uncontrollably throughout the body. The process that cancer takes when invading the body is known as metastasis. Benign cancers do not metastasize, but malignant cancers tend to grow uncontrollably, slowly taking over the entire body to cause long term harm.

Malignant melanoma is an extremely aggressive form of cancer that spreads from one part of the body to another. If not treated early and aggressively, cancers like this can be extremely fatal. Some cancers start as precancerous lesions, while others form in new moles or already existing moles in the body. These are most commonly changes in the skin that do not begin as cancer, but rather become cancer over time. For example, nevus is a word for mole, and dysplastic nevi are moles that are abnormal. These abnormal moles can develop into melanoma over time if not treated early.

Moles or nevi are simply growths that exist on the skin, and they are actually rather common. Very few moles actually ever develop into cancer, but that does not mean that they will be normal moles forever. The average person has between ten and forty moles all over their body, and while some moles are flat, others are raised. Some moles may begin flat but may become raised over time. Moles that are round or oval and smooth, but that eventually change in color, shape, size or orientation should be checked out. While many moles are completely benign in nature, moles and skin cancer are still related and it is important to monitor the moles on your body to make sure that none of them are changing over time.

Dysplastic nevi, which are moles that are abnormal in nature, are not naturally cancerous by any means. However, there is still an ever present chance that these abnormal moles can turn into cancer in time. People who have dysplastic nevi often have a large number of them, and people who have many of these abnormal moles are more likely to develop melanomas. Melanomas can be developed in already existing moles, or in an area of normal skin that will develop into an abnormal mole. For this reason, it is important to understand the correlation between moles and skin cancer, because if you have a lot of moles, especially dysplastic nevi, there is a chance that skin cancer will eventually develop.

One of the most common forms of cancer in existence is basal cell carcinoma, which is a form of chance.

skin cancer. It can be an extremely destructive and mildly disfiguring form of skin cancer and the risk of developing this particular form of skin cancer increases greatly for individuals who have a history of the disease in their families. The risk of developing it also increases with increased exposure to sunlight, as sunlight causes exposure to damaging UV light. Carcinogenic chemical exposure such as exposure to arsenic also increases the

Treatment options for Basal cell skin cancer include surgery, mohs surgery, X-ray, cryosurgery, topical chemotherapy and photodynamic therapy. It is very rarely a life threatening form of cancer, but if you do not treat it in time it can become disfiguring. Basal cell skin cancer can also cause bleeding, and can produce destruction on a local level. Local destruction that it can cause includes eye, nose, ear and lip damage, though this damage very rarely spreads further than the origin point of the tumor. However, long standing tumors that are not treated may be able to metastasize into lymph nodes and other surrounding areas, which can cause significant internal damage to bone and nearby tissues in the area where the tumor is growing.

There are numerous different forms of Basal cell skin cancer that are recognized, including Nodular Basal, Cystic Basal, Pigmented Basal, Superficial Basal and finally Sclerosing or Cicatrizing Basal. Nodular forms include flesh colored papules that are known as rodent ulcers when they ulcerate. Cystic forms are rarer and tend to be harder to distinguish in comparison to nodular skin cancers. Pigmented forms are often confused with melanoma cancers. Sclerosis forms present scar like lesions, and superficial forms present with red scaling patches.

Two thirds of all Basal cell skin cancer instances occur on areas of the body that are regularly exposed to the sun. One third of all instances of it on the other hand exist on areas of the body that are not regularly exposed to sunlight, and this fact emphasizes the idea that genetics may also cause it in some patients even if they are not regularly exposing their bodies to the harmful UV light provided by the sun. It tends to present as a firm nodule which clearly grows within the skin that exists above and below it. Basal cell skin cancer does not normally do much growing on the surface of the skin. The colors associated with it vary from normal skin color to black or dark brown, though there is always a pearly or translucent quality to the skin which is a telltale sign that a tumor is forming.

Basal cell skin cancer is not normally a deadly form of skin cancer, though it is still vital that the cancer be treated early to prevent it from becoming disfiguring. When it metastasizes, it can cause quite a bit of damage both above and below the skin, so that even after the cancer is treated, there will still be something left behind even once the it is gone.

There will be nearly 11,000 deaths from skin cancer in 2006 — about 8,000 from melanoma and 3,000 from other skin cancers, says the American Cancer Society.

Skin cancer is the most common of all cancers and accounts for almost half of all cancers in the United States. There are two types of skin cancer, nonmelanoma and melanoma.

U.S. doctors find more than 1 million cases of nonmelanoma skin cancer, usually in a patient´s basal cells or squamous cells. Exposing skin — the face, ear, neck, lips, and the backs of the hands — to the sun causes most nonmelanoma skin cancer. While they can grow fast or slow, they rarely spread to other parts of the body.

The second kind, melanoma does spread to other areas of the body making it more dangerous. It accounts for just a small percentage of skin cancer, but it causes most skin cancer deaths. Melanoma is a cancer that begins in the pigment cells that produce the skin coloring (melanin) which helps protect deeper layers of the skin from the sun´s harmful rays. Detected early, melanoma is almost always curable.

Photodynamic therapy

Both nonmelanoma and melanoma skin cancers respond to photodynamic therapy (PDT). PDT is a Food and Drug Administration (FDA) approved treatment for skin cancer that combines a light source and a photosensitizing agent (a drug that is activated by light) to destroy cancer cells. It´s sometimes called photoradiation therapy, phototherapy or photochemotherapy and is useful when there are several lesions on the skin or scalp.

A photosensitizing agent, for example fluorouracil, spread on the skin makes PDT work, because the agent collects more readily in cancer cells than in normal cells. Exposing the agent to light makes it react with oxygen to create chemicals that can kill a skin cancer cell. However, the approved light sources can only penetrate a limited depth of tissue; therefore doctors mainly use PDT to treat areas on or just under the skin. It´s less effective for treating large tumors, because the light cannot pass deep into the tumors. Because it´s a localized treatment, doctors don´t use PDT to treat skin cancer that has metastasized.

Doctors sometimes use PDT in precancerous treatments. It usually needs pre-approval by a healthcare provider. Just because the treatment is in the facial area, case managers shouldn´t assume it´s a cosmetic treatment. Check to see the patient´s age, if the patient is over 60 years old, the case is probably not cosmetic. Also, look at the chart to see if there are multiple lesions on the skin or scalp, usually three or more.
