What is Skin Cancer? Risk Factors and Detection is a post from: Skin Cancer Information

Our bodies are made of individual cells, which are made to reproduce, and thus for growth and an extended, healthy life. By vocation, reproduce and die, they have new fresh cells and fully functional to continue to participate in bodily functions. After several cycles of reproduction, which fail to natural cellular degeneration over time or outside influences mutations, some cells to reproduce and die in order to start the normal rate, reproduction and can form a lot and growth. These tumors can be benign or malignant, they may be, in this case they are considered cancers. UV radiation can cause skin cells to mutate and create growths, some benign and malignant certain. This is a benign tumor, and what is cancer of the skin is a question you should ask your doctor.

If you have a rash, lumps or injury that seems not heal, it could be a cancerous tumor. Rather than ignore these symptoms, you should consult your doctor about what they are, even if things should be an obvious reason, a doctor, whatever, to say the risk of cancer.

The symptoms listed above may squamous or basal cell carcinoma, the two most common cancer of the skin without the presence of melanoma are reported. squamous cell layer of the skin. They are round and flat, and protect the environment. Below this layer of cells are basal cells, which can also form tumors.

Most people have an average of 10-40 moles, or nevi, are benign, noncancerous tumors. They appear often in the face, back and arms, places that are frequently exposed to sunlight. Nevi are growths composed of melanocytes mutant cells, the pigment of the skin. They are among the dermis, where sweat glands and hair follicles are located and the skin basal cell and squamous. Melanocyte-cancerous growths, which in turn is melanoma.

Examine your skin regularly for any abnormalities, especially if you have dysplastic nevi, which are irregularly shaped moles. If these changes nevus in any way, including size, shape, color or texture, or irritation of surrounding tissue, you should consult a doctor. When a new dysplastic nevi forms to your body, a doctor may want a biopsy to see if it is cancer. This is usually done by removing the entire mole, and they can all the care you need to get rid of cancer. If the cancer has metastasized tumors helps further in other parts of the body by the migration of cancer cells that play elsewhere, early detection is extremely important.

Do not expose yourself to UV radiation, if you can avoid it. When you go in the sun, you should sunscreen or protective clothing. Tan does not have too much and avoid sunburns, and do not use sunbeds. New research shows that tanning beds are an important risk factor for melanoma, which is the most serious form of skin cancer.

Ask a doctor if you think that the irregularities of the skin have, and you do with your skin and moles, so you can even make inquiries. Any irregularities should a doctor who can tell you what the skin cancer and can make a normal growth or another state to be examined.

Skin cancer represents the most commonly diagnosed malignancy, surpassing lung, breast, colorectal and prostate cancer. Tumors develop primarily on areas of sun-exposed skin, including the scalp, face, lips, ears, neck, chest, arms and hands, and on the legs in women. Contrary to popular conception, skin cancer affects people of all skin tones, including those with darker complexions. Most skin cancers appear after age 50, but the sun’s damaging effects begin at an early age, therefore protection should start in childhood in order to prevent skin cancer later in life.

Types of Skin Cancer

The main types of skin tumours are:

1. Melanomas are skin cancers that form in melanocytes (skin cells that make pigment). Even though it is rare, malignant melanoma is responsible for 75 % of all skin cancer related death cases.

2. Basal Cell carcinomas are skin cancers that form in basal cells (small, round cells in the base of the outer layer of skin).

3. Squamous Cell carcinomas are skin cancers that form in squamous cells (flat cells that form the surface of the skin).

Rarer types of skin tumors are:

1. Neuroendocrine carcinomas which form in neuroendocrine cells (cells that release hormones in response to signals from the nervous system. ) carcinoma of the skin.

2. Dermatofibrosarcoma protuberans.

3. Merkel cell carcinoma.

4. Kaposi’s sarcoma.

Risk Factors

Risk factors for non melanoma and melanoma skin cancers include: unprotected and or excessive exposure to ultraviolet (UV) radiation, fair complexion, occupational exposures to; coal tar, pitch, creosote, arsenic compounds, radium, family history, multiple or atypical moles, and severe sunburns as a child. Anyone with a family history of skin cancer also has an increased risk of developing skin cancer.

Signs of Skin Cancer

Signs of melanoma may include: A large brownish spot with darker speckles located anywhere on your body, a simple mole located anywhere on your body that changes in color, size or feel or that bleeds, a small lesion with an irregular border and red, white, blue or blue-black spots on your trunk or limbs, shiny, firm, dome-shaped bumps located anywhere on your body, dark lesions on your palms, soles, fingertips and toes, or on mucous membranes lining your mouth, nose, vagina and anus.

Signs of basal cell carcinoma can vary depending on the type and may include skin changes such as a: Firm, pearly bump with tiny blood vessels in a spider like appearance (telangiectasias). Signs of squamous cell carcinoma include any: persistent, firm, red bump on sun-exposed skin.

Treatment

Depending on the type of skin cancer, dermatologic surgical treatments include: surgical excision; electrodessication and curettage which involves alternately scraping or burning the tumor in combination with low levels of electricity, cryosurgery and laser surgery. Other dermatologic treatments include radiation therapy and photodynamic therapy (a chemical is applied to the skin prior to exposure to a light source). Mohs micrographic surgery is preferred for large basal cell carcinomas, those that recur after previous treatment, or lesions affecting parts of the body where experience shows that recurrence is common after treatment by other methods.

Skin cancer can be deadly, but nearly all skin cancer can be treated if it is detected and diagnosed early, however skin cancer can recur, so it is important that you examine your skin regularly for any changes and see your doctor for a check-up every six to 12 months.

If you have read a newspaper or listened to the news over the last few years, then you will know that there are always constant warnings telling us to protect our skin against skin cancer. Whilst many people do listen to these warnings, there are still a shocking amount of people who still ignore them.

If you are one of those people that do ignore the warnings you are likely to be thinking that there is no chance of you getting the cancer and that there is no harm in missing an application or two of sun tan lotion. After all, skin cancer takes ages to develop doesn’t it?

Skin Cancer and its Various Forms

Skin cancer is not as rare as some people think that it is. Whilst it is true that staying in the sun unprotected for a little amount of time, rarely leads to skin cancer, it still can occur. There are different forms of skin cancer, though some are extremely rare. The three most common types of skin cancer include:

Melanoma

This is less common than the other two types of skin cancer, though it can be a lot more serious. It develops from the melanocytes in the skin and is usually seen as a pigmented lesion with an irregular shape in the skin. This is definitely the most potentially harmful cancer as it can spread to various different areas within the body. If treated early, the good news is that this type of cancer has a very high cure rate, so get to the doctors as soon as possible for your best chance of recovery!

Squamous Cell Carcinoma

This is usually seen within any part of the body which is exposed to excessive sun. Often occurring in the hands, lower lip, and the forehead, this type of cancer appears as a red bump or an ulceration of the skin which does not heal. The cancer if left untreated can spread to lymph nodes within the affected area.

Basal Cell Carcinoma

Basal Cell Carcinoma is by far the most common type of cancer you are likely to get and it usually appears as a small bump which has a pearly colored appearance. Usually the cancer is found on areas of the body which have had excessive sun exposure. This type of skin cancer does not usually spread to other parts of the body, and will only spread to the skin around the actual cancer.

Overall, Basal Cell Carcinoma is the most common skin cancer but it is not the most serious. Usually people with fair skin are more at risk than others of contracting the cancer, especially people with freckles. Obviously, the longer you expose your skin to the sun without sufficient protection, the more at risk you are of developing skin cancer.

How to Prevent Yourself from Getting Skin Cancer and the Treatments Available

It is really easy to protect yourself against skin cancer, so really there is no excuse for not preventing it. Using an adequate amount of sun protection lotion is a must, and unfortunately many people simply do not bother with it. There seems to be some confusion between how much you should use and what protection factor you should go for. Generally, children and people with fair skin need to be using a higher protection factor than other people. People with darker skin do not tend to get skin cancer as often as people with lighter skin so they do not need a high factor sun lotion.

Sunbeds are also a cause of skin cancer, though cases are rare. So if you do use a sunbed, it is important that you limit your use of it, and contact your doctor to see how often they recommend you should use it.

When out in the sun do not forget to protect your face too. Applying lotion to the ears, nose and neck will help to protect those sensitive areas from the sun.

If you do notice any changes in your skin such as moles, lesions or sores which do not heal, it is always better to consult your doctor immediately. If caught early, most skin cancer can be cured. There are various forms of treatment for skin cancer including surgery, radiotherapy and chemotherapy. The treatment which you will receive depends upon your age, health and the size of the cancer. However, surgery is the most common form of treatment and it is usually done as an outpatient procedure.
