Skin Cancer Essay

     Distinguishing melanoma may seem hard to do, but is not so once a person is informed on what they should be looking for. They may appear similar to moles, and may be blue or black in color. Though they will usually lack the symmetry and border regularity of a common mole, and may have variance in their coloring. Melanomas can either appear suddenly, or develop slowly near a preexisting mole. In rare cases, melanomas may form on top of previously formed moles or birthmarks, but will also come with the effects of pain, itching, or bleeding. These moles may begin to exhibit new and/or strange characteristics such as

Skin cancer is a condition where cancerous cells form in the epidermis. The epidermis is the first layer of your skin. Melanoma can be on any part of the body (Egan 23-24). This form of skin cancer can be treated in the early stages of formation. Basal cell cancer is one of the most common types of skin cancer, this cancer may also happen on the sun exposed skin and on the face (Egan 10).Squamous cells are the second most common form of skin cancer. Squamous cells form on sun exposed skin (Egan 11). For example, it could potentially form on the shoulders, neck, or hands (Egan 10-11). Each stage of skin cancer may vary depending on the person.

Skin cancer is a term used to describe cancer in skin tisssues. The skin is made of several layers. Skin cancer is classified according to the layer it develops in. Skin cancer is classified according to the layer it develops in. The epidermes is the skin’s outer layer and is made up squamous cells, basal cells and melanocytes

The largest organ of the human body is your skin. It is your body’s first line of defense against infections, injuries, heat, and sunlight. It also helps in controlling the temperature of your body and getting rid of the excess water and salt by sweating it out. Skin cancer is also known as cancer of the sun. Excessive amounts of ultra violet lights affect your skin in negative ways, possibly leading to Melanoma skin cancer. Melanoma is the most serious type of skin cancer there is and can often times be fatal (McClay).

Unlike other cancers which we can develop, melanoma can often be detected on the skin which allows doctors to treat it at its early stages resulting in less complications and lower death rates to patients, again if left undetected at its early stages this can easily spread to distant areas and distant organs. Once melanoma has spread to other areas of the body which is classified as stage IV it is diagnosed as

Although there are several types of skin cancer, the most aggressive form is melanoma. This cancer of the skin involves mass replication of the pigment producing melanocyte cells, which are located in the epidermis, below the basal layer. There are several factors involved with the onset of melanoma including, exposure to ultraviolet rays, genetic predisposition, numerous nevi (moles), immunosuppression, and environmental exposure to carcinogens.

Melanoma is a dangerous invasive cancer which starts in melanin producing cells (melanocytes) usually located at the bottom of the skins epidermal layer. Although certain individuals have a genetic propensity for melanoma, it is usually triggered by excessive UV exposure from sunlight or tanning beds (Mayo Clinic, 2016a). At early stages it is relatively easy to treat, however, recurrences are common. At later stages melanoma treatments are less effective since it tends to metastasize and spread easily through the lymphatic system (Mayo Clinic, 2016a).. The root cause of malignant melanoma is due to mutations in the p53 gene protein which invariably leads to further mutations.

Basal Cell Carcinoma – Most common type of skin cancer it accounts for 80% of non-melanoma cancers. If left untreated it can affect skin, bone tissue, and cause death.

The first type of skin cancer is called basal and squamous cell skin cancer. Squamous cells around the outer layer of the epidermis that are flat and shed as new cells form. () The basal cells are on the lower part of the epidermis and constantly divide in order to replaces the squamous cells. () Basal cell cancer is the most common of all the types of skin cancer. This kind of skin cancer is most likely caused by sun damage and is usually developed in the head and neck areas.

I chose my topic because I have a skin condition, and I thought it might be a good idea to research different skin disorders. I have eczema on my foot and it was a very irritable skin disorder to go through. But thanks to the miracle of modern day medicine, all I'm left with is a scar and it is barely noticeable. Since that's my skin disorder I will begin with eczema and work my way down to pressure sores.

C. Melanoma Skin Cancer is the most dangerous form of skin cancer, it kills one person per hour, these cancerous growths are most often caused by ultraviolet radiation from sunshine or tanning beds. These tumors originate in the pigment-producing melanocytes in the basal layer of the epidermis. Melanoma is caused mainly by intense, occasional UV exposure (frequently leading to sunburn), especially in those who are genetically predisposed to the disease. Often the first sign of melanoma is a change in the size, shape, color or feel of a mole.

There are certain time periods throughout the day, where sunlight exposure is most severe. Therefore, avoiding the sun from the hours of ten in the morning to four in the afternoon is one of the ways in which you could avoid receiving a harsh sunburn that could accumulate to potential skin cancer in the future. Also, preventing a sunburn is simply the easiest way to prevent future skin cancer. If one is planning to go outside in the time where the UV rays are most severe, one must apply the correct amount of sunscreen in order to block the rays from penetrating one’s skin. Another way to protect oneself is to cover up any exposed skin that could be sunburned. This includes putting on hats, and wearing specific clothing that hides all of your

Obtaining an accurate pathologic diagnosis can be challenging, however. Many characteristic features on histologic examination of melanomas aid in the diagnosis, but there is currently no single feature that is pathognomic for the disease. Histologic examination of melanoma classically shows cytologic atypia with enlarged cells with aberrant, large, pleomorphic, hyperchromic nuclei and prominent nucleoli in company of increased mitotic activity. A pagetoid growth pattern with upward growth of the melanocytes is considered highly suspicious for melanoma.[4] Immunohistochemical stains are typically used for complementary purposes. S-100 and homatropine methylbromide (HMB45) usually stain positive in these tumors. Due to S-100’s high sensitivity

In recent years, cancer prevalence has been increasing globally. It is now one of the top 10 causes of death among the middle and high income countries worldwide (World Health Organisation, 2008). In Singapore, cancer has surpassed cardiovascular disease and become the top killer over the last 3 years (Ministry of Health, 2007). Breast cancer tops the chart among Singaporean women (Health Promotion Board, 2007). Thousands of women are diagnosed with breast cancer annually and it causes approximately 270 deaths each year (Jara-Lazaro, et al., 2010). The lifetime risk that a woman in Singapore getting breast cancer is now 1 in every 17 which has risen compared to past two decades (National Cancer Centre Singapore, 2006). Hence, breast
