Skin cancer cases

Skin cancer is the most common type of cancer in the world. Over 2 million cases of this disease are diagnosed each year and if not detected early it can lead to surgery and even death. Every year between 40 and 50% of all cancer cases are diagnosed as skin cancer. There are two main types of skin cancer; malignant melanoma and non-melanoma. The most common types of non-melanoma cancer are Basal cell carcinoma and Squamous cell carcinoma, and approximately 79% of Malignant Melanoma cases relate to deaths. These cancers account for only 4% of all skin cancer cases but are by far the most dangerous. Melanoma is more likely than non-melanoma to spread to lymph nodes and other parts of the body. It is estimated that over 12 thousand people with some type of skin cancer will die this year.

The skin is the largest organ of the human body, measuring approximately twenty square feet for the average adult. It can be considered as the most resilient organ in the human body. The skin is divided into layers; the Epidermis (upper most), the Basement Membrane, the Dermis, and the Hypodermis/Subcutis. It covers the internal organs and bones and protects them from injury and germs, and prevents the loss of too much fluid. The skin is vital in the control of body temperature and it gets rid of some wastes through perspiration. Certain cells in the skin communicate with the brain to allow temperature, touch, and pain sensations.

Skin cancer is the uncontrolled growth of abnormal skin cells that when left unchecked, spread from the skin to other tissues and organs of the body. More cases of skin cancer are being diagnosed as time goes on. Studies have shown that heavy exposure to the sun's ultraviolet radiation (UVR) lead to skin cancer and other skin problems. These studies have shown that 65 to 90% of melanomas are caused by over exposure to ultraviolet light (sunshine, tanning beds and tanning lights), but it has also been shown to run in families and may also be genetic.

The second most common form of skin cancer is Squamous cell carcinoma (SCC), and approximately 700,000 cases are diagnosed each year with approximately 2,500 deaths. It is one of the less aggressive skin cancers in that when detected early it may be easily controlled or removed through minor surgery. This cancer is an uncontrolled growth of abnormal cells arising in the Squamous cells, which compose most of the skin's epidermis (upper layers).

This type of cancer is mainly caused by cumulative UVR exposure over the course of a lifetime and may not occur until many years after receiving the original damage to the skin, which makes it necessary to see a dermatologist at its first signs. The most common areas for this cancer are those that are frequently exposed to the sun, such as the rim of the ear, lower lip, face, bald scalp, neck, hands, arms and legs. Skin damage can appear as wrinkling, changes in pigmentation, and loss of elasticity in the skin.

Exposure to UVR s the cause for most cases of Squamous cell cancer. The condition develops due to the fact that UV radiation damages the DNA in an individual's skin cells. The more damage to the DNA, the more likely the skin cells will grow out of control and develop a Squamous cell carcinoma. Most cases of Squamous cell cancer may be prevented, and there are several ways to do this; by applying sunscreen, wearing protective clothing, avoiding midday sun, limiting your time in direct sunshine, don't use tanning beds or lamps, and checking your skin regularly.

Squamous cell cancer is a easily treatable and preventable type of skin cancer. However, it can still be deadly and needs to be detected and treated early. Squamous cell cancer very rarely causes further problems when identified and treated early. Untreated, it can grow large or spread to other parts of your body, causing serious complications. Call for an appointment with your health care professional if you observe a sore or spot on your skin that changes in: appearance, color, size, texture, or if an existing spot becomes painful or swollen, or if it starts to bleed or itch.

Skin cancer protection

Skin cancer is another common type of cancer. As the name suggests, skin cancer is a cancerous condition of skin.

Types of skin cancer

There are three types of skin cancers: basal cell skin cancer, squamous cell skin cancer and the dangerous malignant melanoma. Since skin cancer is very closely associated to skin pigmentation, the fair skinned people are more at risk of developing skin cancer as compared to the dark skinned ones.

The cause of skin cancer

Prolonged contact with direct sunlight is what causes skin cancer. The main culprit in the direct rays of sunlight is the UV radiation (i.e. Ultra violet rays). Thus most of the preventive action against skin cancer is concentrated on avoidance of UV rays.

Protection against skin cancer

Protection against skin cancer is probably easier than the protection against other types of skin cancer. Still, a number of people ignore it and become target of this dreaded disease. Here is a list of things that can protect you from skin cancer:

1. Clothing: Since skin cancer is caused by prolonged contact of UV rays with your skin, the more you cover your skin with clothing, the lesser is your risk of developing skin cancer. Full sleeved clothes, long skirts and trousers, big hats/caps, high necks etc are all helpful in preventing skin cancer.

2. Sun screen lotion: There are a number of skin care products available in markets that offer effective protection against skin cancer. Sun screen lotions and creams that have a SPF (Sun Protection Factor) of 15 or more are much recommended for use.

3. Avoid exposure to UV rays: This is the best protection against skin cancer. If you can time your outdoor activity during those periods when the UV rays are less intense, you are automatically protected against UV rays. Thus getting out either early in the mornings of later in the evenings is the best.

4. Diet: Carotenoid fruits and vegetables are also known to help prevent skin cancer.

Detection of skin cancer

The various techniques for protection against skin cancer can only reduce your risk of contacting skin cancer. If you are really unlucky (or if you have not taken the protective measures against skin cancer), you might still get affected by skin cancer. In such a case, early detection can make the difference between curability and non-curability. Timely consultation with a qualified doctor, regular check-ups and accurate diagnosis can prevent skin cancer from becoming really dangerous for you.

Deadly Skin Cancer Types

An important warning for us all with regard to skin cancer types. Today more patients than ever survive dangerous melanoma than in past generations, but the rate of death for one form of this disease hasn't budged in 30 years.

Nodular melanoma accounts for 14% of melanomas that are diagnosed, but makes up a startling 37% of untimely deaths from the disease according to a recent study.

The reason this form of cancer contributes to so many deaths is that it doesn't always look like what we expect to see. It can appear without warning on the surface of the skin and can be hard to spot because it's often light or nearly colorless, and doesn't adhere to the ABCD characteristics we've all been taught to look for.

Just like the more well known radial melanoma, nodular melanomas start out in skin cells that are called melanocytes that product melanin. Most melanomas stay in the skin's top layer, going down no more than one tenth of a millimeter. Radial melanomas are easier to see as the diameter goes up.

For nodular melanoma the cancerous cells reach a point where they start to grow vertically, sending roots into the fat and other tissues of the body. The depth of the cancer determines how likely you are to survive. For a cancerous growth that goes 3.5 to 4 millimeters deep, only 60% of patients will live for five years.

This latest study examined over 100,000 cases of melanoma diagnosed between the years 1978 and 2007.

They saw that at least 20% of nodular melanomas were fatal. You should understand that there's an acknowledged limitation of the work - not all physicians report the type of melanoma and the team was unable to double check the reports during the study.

While public health officials and others have done a great job of getting the word out about ABCD characteristics when it comes to identifying skin cancer, experts now believe other letters should be added to the mix to help identify the nodular types of these cancers. We've been taught to watch for any of these...

- Asymmetry, one side doesn't match the other

- Borders, where moles have irregular edges

- Color, color changes or a variety of colors

- Diameter, anything over 6 millimeters wide

But we should also be watching our skin surface for E, F and G as well. Any mole or other growth that has all of these characteristics should be checked by a dermatologist at once. They are...

- Evolving, where the mole or nodule is changing quickly over a short period of time

- Firm to the touch

- Growing for more than two to three weeks

Also good to know, nodular melanoma can happen in a mole, but are more likely to develop without warning on normal skin

In most cases the various skin cancer types, including melanomas are easy to detect, treat and cure. Dermatologists suggest that you get to know your own skin by doing full body self-exams once each month. If you're worried about something you see... get to the doctor right away. Often patients realize something is wrong. Don't give up if the first physician you see doesn't respond as you like... keep looking until you find one who will take action.
