The majority of these are basal cell carcinomas. These are usually localized growths caused by excessive cumulative exposure to the sun and do not tend to spread. ------------------------------------------------- [edit]Classification There are three main types of skin cancer: basal cell carcinoma (BCC), squamous cell carcinoma (SCC) and malignant melanoma. each of which is named after the type of skin cell from which it arises. Basal cell carcinomas are present on sun-exposed areas of the skin, especially the face.
Some other factors that contribute to skin cancer is multiple moles, exposure to coal and arsenic compounds, and scars from disease and burns. One symptom of skin cancer is Basal cell carcinoma that usually occurs in your face, ears, or scalp. Basal cell carcinoma appears as a pearly or wavy bump, or a flat, flesh-colored or brown scar-like lesion. Another symptom is squamos cell carcinoma occurs on sun-exposed areas of your body, face, lips, ears, and hands. It appears as a firm, red nodule, or a flat lesion with a scaly, crusted surface.
Vitiligo Vitiligo is a common, progressive depigmenting skin disorder characterized by annihilation of melanocytes in the epidermis, the mucous membranes, and the eyes and infrequently in some hair bulbs. The word vitiligo comes from the Latin word “vitium” meaning a blemish. This disease happens in all sexes, of all ages and of all races, but mostly African-Americans. The symptoms of vitiligo include white patches, or depigmentation on the skin. Depigmentation can be mostly found on sun-exposed areas of the body such as the hands, feet, arms, face, and lips.
With that being said, in reference to the first paragraphs statement alluding to weather skin cancer is an inherited gene mutation or if it is due to exposure to the UV light. Let’s take a closer look to make it clearer; most fair skin, light hair, freckled, and light eyed people have a higher risk of developing skin cancer. However they HAVE to be exposed to sun light in order for it to happen. On the opposite side of that a darker skinned, darker hair and dark eyed person may not be as susceptible to skin cancer but if they are exposed for long enough and often enough they too can get skin cancer. In addition to them getting skin cancer it is more “likely” that they will get it in an area that isn’t exposed to the sun as often, i.e.
Most bacteria are killed by the effects of UV light and it is routinely used to sterilize surfaces, such as work areas of transfer hoods used for the inoculation of cultures. The primary lethal effects of UV are due to its mutagenic properties. When DNA absorbs UV light; it causes the formation of pyrimidine dimers. These form when a covalent bond forms between two adjacent thymine or cytosine molecules in a strand of DNA (Brown, 2012). These dimers deform the DNA molecule, so that DNA polymerase is unable to replicate the strand of DNA past the site of dimer formation and genes can no longer be transcribed.
In professionals’ eyes tan is considered a skin damage that causes premature aging of the skin, links directly to skin cancer, and puts addicted youth in danger. Tanning beds speed up the aging process of the skin. The studies show that the skin exposed to the UV rays decrease the life of healthy skin. Many people that use tanning beds on a regular basis will notice how quickly their skin loses elasticity and its youthful glow. The skin starts to sag, develops wrinkles, and feels more leathery.
This is called choridal neovascularization. These blood vessels leak blood and fluid into the retina, causing distortion of vision. The dry form of macular can also lead to the wet form. Only about 10% of patients with macular degeneration develop the wet form, they make up the majority who experience serious vision loss from the disease. Macular degeneration can be passed from parent to child, smoking, high blood pressure, high cholesterol, obesity, and being light skinned, female and having light eye color are also risks for macular degeneration (webmd copy write 2005-2014, LLC) Glaucoma is an eye disease characterized by dysfunction of the ocular drainage system.
Furthermore, different stages of cancer will be treated with different methods and therapies. Most and many cancers will develop abnormal tumors. Killing the cancer cells and isolating the tumor will be ideal for preventing the spreading of the disease throughout the body. In Hong Kong, there are two main ways to treat cancer; Radiotherapy and Chemotherapy. Radiotherapy can be done mainly with two machines.
Even with all of the scientific research skin cancer is still extremely hard to diagnose. UV rays that are given off by sunlight are the main danger. Skin cancer comes in a few different forms melanoma, basal cell, and squamous cell. Malignant Melanoma is by far the most deadly form, killing almost 75% of people that are diagnosed. Skin cancer visible symptoms have a lot to do with moles.
Yet the benefits outweigh the risks by far because if the procedure is done correctly all the cancerous cells in that isolated area will be eliminated entirely. Keywords: Targeted Chemotherapy, molecular targeting, isolated infusion, Cisplatin, angiogenesis, alkylating antineoplastic agent Chemotherapy is the therapeutic use of chemical compounds for the treatment of cancerous diseases. Normally chemotherapeutic drugs are given intravenously in low dosages over large periods of time, this is called an antineoplastic drug regimen. Antineoplastic drug regiments do work to terminate the quickly dividing tumorous cells, but unfortunately this method also kills normal, healthy cells found in the many soft tissues in the human body and can cause significant damage to healthy organ systems. Instead medical researchers have developed targeted chemotherapy to better treat cancer without damaging healthy sections of the body.
