Information About Skin Cancer

Cancer that is formed in the tissues of the skin is known as Skin Cancer. It is one of the most common kinds of cancer that affects men and women. This cancer affects about a million people every year and there are many factors that cause this including excessive sun exposure, tanning, weak immune systems, etc. Read on to get a complete awareness of this most common form of cancer and on steps to prevent it.

How is skin cancer caused?

When the skin cells modify and multiply in an abnormal fashion, the uncontrollable growth causes the development of a mass known as a tumor. This tumor that occurs in the skin is also known as a lesion and these cancerous growths are malignant in nature which causes the destruction of adjacent cells leading to random growth. These tumors flow through the blood stream and affect other remote organs also during the advanced stages of skin cancer.

Types of skin cancer

Skin cancer is divided into two kinds depending on their ability to spread around. The two types of skin cancer are non-melanoma and melanoma. Non-melanoma includes the type basal cell carcinoma and squamous cell carcinoma in it.

1. Melanoma - The cancer that affects the melanocytes or the skin cells that create the pigments.
2. Basal cell carcinoma - The cancer that affects the lower part of the epidermis or the outer layer of the skin.
3. Squamous cell carcinoma - The cancer that affects the squamous cells or the flat cells that form the skin surface.

Basal cell carcinoma and squamous cell carcinoma normally do not spread to other parts of the body whereas melanoma is a dangerous form of skin cancer which spreads to other parts of the body. The major ratio and the most common type of skin cancer are the carcinoma types with the aggressive melanoma forming the least portion.

Symptoms of Skin Cancer

The symptoms of skin cancer are skin changes which take time to heal along with ulcers. Sometimes skin discoloration and changes to moles on the skin can also been seen. The most common symptom is a small lump that is shiny and pale in color or a firm red lump. Some types of cancer also are associated with rough and scaly patches or flat scaly patches of red or brown color. Also beware of any new suspicious growth and consult a physician in such cases. Though these growths are most of the times painless, they can also be painful at times.

A smooth round bump is normally developed on the head, shoulder or neck with signs of crusting and bleeding with development of the tumor in cases of basal cell carcinoma. In squamous cell carcinoma, a thick red color patch along with ulcer and bleeding can be developed. Brown or blackish lesions are formed in cases of melanomas. The lesion exhibits change in size, color or shape as a symptom of the melanoma becoming malignant.

Diagnosis of Skin Cancer

This cancer is diagnosed by the physician in two main methods. The first and the most common method is the skin examination. In this method the doctor looks out for any abnormal growth or irregularity in the skin. This can be followed by a biopsy in case of finding any abnormal growth. In case of biopsy, the affected area or abnormal growth is well studied under a microscope to check for the presence of cancerous cells.

Treatment of Skin Cancer

Surgery is one effective method for the treatment of non-melanoma cancer types. The complete procedure of surgical treatment begins with surgery and includes follow-up methods of radiation therapy and chemotherapy. In the surgical methods, the lesion and a calculated amount of tissues around it is removed so as to make the body tumor free. The Moh's micrographic surgery is one effective technique that is used for this process.

Prevention of Skin cancer

Early diagnosis and detection can help treat skin cancer before it turns dangerous and hence self evaluation of your skin on a regular basis is a must on a frequent basis. Look for any kind of abnormal changes, discoloration or growth in your skin. You can also undertake a doctor visit once a year to detect any signs or symptoms of cancer. In certain cases of high-risk situations, you can consult a skin specialist on a regular basis to screen for this cancer.

Skin cancer can be prevented by adopting a few basic tips which can be very useful in your daily life.

1. Use Sunscreens - 90% of the skin cancers are known to be caused by harmful UV radiations and sunscreens are the best protector when you are someone who spends a lot of time outdoors. UV rays damage our cell DNA structure and modify them making them cancerous. Minimize outings during the time when the sun is at its brightest. Also try to maintain your presence within the shade where ever possible. But even if you are in a shade, remember to wear your sunscreen,
2. Avoid excessive tanning - Artificial lights as in tanning beds, lamps and booths, all contain UV rays and increase the chances of melanoma.
3. Wear protective dressings - Though sunscreens do protect, you can consider wearing protective dressings like a hat or sunglasses, which can protect your eyes and facial skin from the sun.
4. Avoid childhood sunburns - Most of the times, a burn during your childhood can increase your risk of being affected with skin cancer along the years as you grow. Thus it is required that you monitor kids when they are in the sun reducing their exposure.
5. Eat healthy - A weak immune system is a ready agent for skin cancer. Make sure that you include lots of fresh fruits and vegetables so as to improve your body's immunity power.

People who run a higher risk of Skin cancer

Though many people are equally exposed to the chances of this cancer, there are a few who run a higher risk. Individuals with a family medical history of skin cancer or those who possess fair skin tone and freckles run a higher risk. Also people who are addictive to tanning and spend a lot of hours outdoors in the sun along with a weak immune system also possess equal risks of getting this cancer.

Skin Cancer - Basal Cell Carcinoma (BCC)

In the United States, Basal Cell Carcinoma (BCC) accounts for 90 percent of all skin cancers in the southern states, and 47 percent in the northern states. Basal Cell Carcinoma is the most common form of skin cancer in Australia and New Zealand, representing 70-80% of diagnosed skin cancers. Occurrence of Basal Cell Carcinoma mainly occurs on the head and neck. It occurs less often in Asians and rarely among darker skinned races. As with all skin cancers the risk is considered to be related to sun exposure. The positive about Basal Cell Carcinoma is that it is slow-growing and rarely metastasizes throughout the body. However, it is locally destructive and can invade neighboring bone and nerve tissue.

Description - BCC is a malignant epithelial cell tumor that begins as a papule (a small, circumscribed, solid elevation of the skin) and enlarges peripherally, developing into a crater that erodes, crusts and bleeds. BCC originates in the basal layer of the epidermis, the lowest layer of skin.

Signs and Symptoms of Basal Cell Carcinoma - There are five typical characteristics of basal cell carcinoma that are quite different from each other. Two or more features are frequently present in one tumor. BCC sometimes resembles non-cancerous skin conditions such as psoriasis or eczema and requires diagnosis by a trained person. The five warning signs of basal cell carcinoma are:

1. An open sore that bleeds, oozes or crusts, and remains open for three or more weeks. A persistent, non-healing sore is a very common early manifestation.
2. A reddish patch or an irritated area, frequently occurring on the chest, shoulders, arms or legs. Sometimes the patch crusts. It may also itch or hurt. At other times, it persists with no noticeable discomfort.
3. A smooth growth with an elevated, rolled border and an indentation in the centre. As the growth slowly enlarges, tiny blood vessels may develop on the surface (telangiectases).
4. A shiny bump (nodule) that is pearly or translucent and is often pink, red or white. The nodule can also be tan, black or brown, especially in dark-haired people, and can be confused with a mole or melanoma.
5. A scar-like area (white, yellow, or waxy in appearance) which often has poorly defined borders. The skin itself appears shiny or taut. Although a less frequent sign, it can indicate the presence of a more aggressive tumor.

Diagnosis of Basal Cell Carcinoma - Diagnosis is almost always by biopsy. Tissue is cut away from the site and examined under a microscope.

Medical Treatment of Basal Cell Carcinoma - Allopathic treatment depends on the size and type of tumor. There are various types of surgery or non-surgical treatments chosen from.

Non-surgical treatment of BCC - Allopathic non-surgical treatments have low success rates.

• Topical application of 5-fluorouracil for 2 to 12 weeks is only beneficial for superficial BCC. Fluorouracil is used to prevent excess cell proliferation as found in skin cancer and psoriasis. It prevents the formation of RNA which in turn prevents the formation of DNA.
• Imiquinoid cream -currently the use of Imiquinoid cream is considered experimental. It is an immune response modifier that stimulates the immune system to release cytokines that destroy cancer cells. Treatment causes significant skin irritation. Not all types of BCC are affected.
• Ionizing radiation: Superficial x-ray. It results in radiation damage, therefore it is used more with older patients. Impaired immune function and general malaise also usually results. Used for facial BCC and appears less effective for BCC occurring elsewhere.

Surgical Removal of BCC - Surgery is the most studied, and most used treatment for removal of a BCC in allopathic medicine. The effectiveness of surgery depends very much on the skill of the surgeon. Various surgical methods:

• Electrodessication and Curettage - the BCC is burned and removed with a scalpel. The main disadvantage of this method is that the tumor often tracks down hair follicles. (9)
• Cryosurgery - liquid nitrogen to freeze burn the BCC.
• Excision surgery- the BCC is cut from the skin with a scalpel. To increase the likelihood of complete removal of the tumor, a portion of normal-appearing skin surrounding the BCC is removed.
• Microscopic or MOHS surgery - the BCC is cut from the skin, along with some of the healthy surrounding tissue. This is examined under a microscope to check for any remaining cancer cells. Tissue is then taken in increments of thin layers of skin, until no more cancer cells are detected. Mohs is the most effective allopathic medical treatment (99% cure rate for primary BCC, 90-95% for recurrent BCC).
• Laser surgery. Lasers are also used as a secondary therapy when topical medications or other techniques are unsuccessful.

Recurrence of BCC - Once a basal cell carcinoma has been removed, another growth can develop in the same place or nearby area. It has been found that 36% of people who develop a basal cell carcinoma will develop a secondary primary BCC within the next 5 years. Radiotherapy can result in more aggressive and invasive cells in a recurrent BCC.

Effective Alternative Treatments - Allopathic medicine is often successful in completely removing BCC's but obviously also often fails, given the high number of recurrences suffered by many people with repeat visits to the doctor and then specialist. These treatments don't always work as well as expected or hoped.

Skin Cancer Statistics

Skin cancer is the most common form of cancer in the United States. Skin Cancer Prevention Ultraviolet (UV) rays can reach you on cloudy and hazy days, as well as bright and sunny days. Skin cancers account for about 80% of all new cancers diagnosed each year in Australia. Skin cancer costs the health system around $300 million annually, the highest cost of all cancers. The two most common types of skin cancer—basal cell and squamous cell carcinomas—are highly curable. However, melanoma, the third most common skin cancer, is more dangerous, especially among young people. In 2006,*2 53,919 people in the United States were diagnosed with melanomas of the skin, 30,560 of them men and 23,359 of them women. That same year,2 8,441 people in the United States died of melanomas of the skin, 5,477 of them men and 2,964 of them women.

What is Basal Cell Carcinoma skin cancer?

What is Basal Cell Carcinoma skin cancer?  The most common of skin cancer, Basal Cell Carcinoma skin cancer,is not as dangerous as other skin cancers, but it can still be extremely harmful, and is still considered by medical science as a malignant skin cancer.  This is because of the disfigurement and destruction the basal carcinoma skin cancer can cause. This form of skin cancer is the least deadly and with proper treatment can be completely eliminated, often without scarring. Basal Cell Carcinoma skin cancer symptoms
Basal cell carcinoma skin cancer symptoms are quite different than others. In one tumor, there may two or more symptoms may occur. Plus, basal cell carcinoma skin cancer symptoms sometimes resemble other non-cancerous skin conditions, such as psoriasis or eczema.
BCC skin cancer symptoms

It suggested to learn basal cell carcinoma skin cancer signs and examine your body regularly for at least one time in a month, also make sure you use full-body mirror and a hand-held mirror.
Skin cancer symptoms

These are basal cell carcinoma skin cancer symptoms and signs that often occur:

1. 80% basal cell carcinoma shows on the head and neck.
2. An early basal cell carcinoma skin cancer symptom is an open sore that bleeds, oozes or crusts, and remains open for three or more weeks.
3. The tumor looks like a raised, smooth, pearly bump. This tumor color is often pink, red or white. The bump can also be tan, black or brown, especially in dark-haired people, and can be confused with a mole. These skin cancer symptoms often occurs on the part of the body that exposed to the sun, such as: neck, head and shoulder. As the tumor grows, you may see small blood vessels within the tumor.
4. The tumor area fells irritated and reddish colored. This symptoms frequently occurring on the chest, shoulders, arms or legs. Crusting and bleeding in the center of the tumor frequently develops. It may also itch or hurt. At other times, this basal cell skin cancer symptom persists with no noticeable discomfort.
5. A scar-like area (white, yellow, or waxy in appearance) which often has poorly defined borders. The skin itself appears shiny or taut.

However, even if basal cell carcinoma symptoms show a less frequent signs, it can indicate the presence of an aggressive tumor.
