Cancer occurs when normal cells undergo a transformation and grow and multiply without normal controls. As the cells multiply, they form a mass called a tumor. Tumors are cancerous only if they are malignant. This means that they encroach on and invade neighboring tissues (especially lymph nodes) because of their uncontrolled growth. Tumors may also travel to remote organs via the bloodstream. This process of invading and spreading to other organs is called metastasis. Tumors overwhelm surrounding tissues by invading their space and taking the oxygen and nutrients they need to survive and function. There are three major types of skin cancers: basal cell carcinoma, squamous cell carcinoma, and melanoma. The first two skin cancers are grouped together as non-melanoma skin cancers. Basal and squamous are cancers that are most often found in areas exposed to the sun, such as the head, neck, and arms, but they also can occur elsewhere. The two cancers are not as dangerous as Melanoma. They look more similar to each other, that people diagnosed themselves wrong. Melanoma is more dark like a mole. Its very dangerous of skin cancer. Might want to quit going into a tanning bed because it is most likely to cause this tumor. Melanomas may not cause symptoms and are frequently found by a doctor during a routine skin examination. Less commonly, melanomas may bleed, itch, or cause pain. All of the skin cancer that is listed all deal with UV lighting. It's just that, Melanoma type is worst. They all have similar causes and treatments. The negative affect is the color and symptoms.
Four main types of basal cell carcinoma are seen: nodulo-ulcerative; pigmented; morpheaform and superficial. Diagnosis is by histological evaluation although many tumours have a characteristic clinical appearance. The differential diagnosis is large. The main treatment modalities are surgery and radiotherapy. Each has advantages and disadvantages. The choice of treatment depends on many factors. Principles of treatment include identification of high-risk patients to enable early detection, complete removal of the lesion, and careful follow-up to detect recurrence or new lesions. Basal cell carcinoma forms in the outer layer of the skin, called the epidermis. Most basal cell carcinomas are a result of long-time, repeated sun-exposure or occasional intense sun-exposure. That’s why the cancer is most common on areas of the skin regularly exposed to the sun, including the face, neck, scalp, shoulders, back and ears. Anyone can develop this type of cancer but it is more common in light-skinned individuals with blonde or red hair and light green or blue eyes. In general, basal cell carcinoma is a slow growing cancer and it is rare for it to metastasize to other areas of the body. It will usually only spread to surrounding tissues in the skin or bone. After a doctor examines the carcinoma, a biopsy is needed to confirm the cancer. If tumor cells are visible, treatment is required. Treatment will vary based on the type, size, depth and location of the carcinoma as well as individual patient concerns. To prevent this cancer, limit the time spent in the sun, wearing sunscreen and protective clothing and checking the skin regularly for new spots or moles is the key to preventing and catching basal cell carcinoma early. Picture shown above, is a microscopic view. In the article there are multiple pictures shown of the cancer. Typically the article describes the risk factors and who is mostly likely affected. Standardizing what age this occurs to and type of skin. Unlike Melanoma it is not as deadly, however cancer is cancer.
Melanoma is in a form of a malignant tumor, found in pigments on the skin. Melanoma is the most dangerous type of skin cancer. Because melanocytes are involved, most melanomas are black or brown in color. However, if the cancerous cells stop producing pigment, a melanoma may be skin-colored, pink, red, or purple. The best way to diagnose someone with melanoma is through biopsy. The weird skin texture that looks like melanoma is removed for a doctor to look at and analyze. Melanoma is treated depending on how far along it is developed or deep it is in the skin, doctors can treat it in different ways. Such as, medical procedure, surgery, radiation therapy and of course chemotherapeutic. To prevent Melanoma is to keep away from the sun. This is the reason why sunscreen was invented. This resource was chosen because it clearly identifies the 4 different stages "A,B,C & D". This article also explains the signs and how they're caused. There are details on what to do in able to treat this cancer and how to prevent this dangerous cancer. This picture was chosen because of the different stages. It's good to observe the differences between A,B,C & D. There also shows a small description of each.
One in five Americans will develop skin cancer in their lifetime. There two main types of carcinoma are basal cell carcinoma (BCC) and squamous cell carcinoma (SCC). Both BCC and SCC are much more common than melanoma and are referred to as non-melanoma skin cancer. Squamous cell carcinoma is less common than basal cell carcinoma but more likely to spread (metastasize). The incidence of SCC has increased by up to 200% in the past three decades in the US. Carcinoma can affect the surface tissue (epithelium) of numerous other organs. Diagnosis is made after a patient presents with signs and symptoms to a clinician, who will then take a history, conduct an examination and arrange a biopsy. Treatments are similar to those for other types of cancer and include surgical removal, drug therapy and other locally applied treatments and radiation therapies. The main preventive measure against carcinoma is to reduce exposure to ultraviolet light, by avoiding peak daylight and wearing protective clothing and effective sunscreen, for example. Some risk factors are unavoidable, such as rare syndromes and a number of conditions and medications that result in immunosuppression. Regular self-examination of the skin is an important tool in detecting the first signs of skin cancer so as to access prompt and effective treatment. Basal cell carcinoma arises in, unsurprisingly, the basal cells found deep in the skin's epidermis, below the squamous cells. These rounder skin cells form the base layer of the epidermis that meets the dermis. The picture was chosen for this article because it shows the different between the basal cell and squamous cell. They look a bit similar and this example helps more to identify which is which. It is important to analyze the two apart. The article clearly gives a brief description of how it is diagnosed, treat and prevented.
