Photodynamic Therapy for Skin Cancer

There will be nearly 11,000 deaths from skin cancer in 2006 — about 8,000 from melanoma and 3,000 from other skin cancers, says the American Cancer Society.
Skin cancer is the most common of all cancers and accounts for almost half of all cancers in the United States. There are two types of skin cancer, nonmelanoma and melanoma.
U.S. doctors find more than 1 million cases of nonmelanoma skin cancer, usually in a patient´s basal cells or squamous cells. Exposing skin — the face, ear, neck, lips, and the backs of the hands — to the sun causes most nonmelanoma skin cancer. While they can grow fast or slow, they rarely spread to other parts of the body.
The second kind, melanoma does spread to other areas of the body making it more dangerous. It accounts for just a small percentage of skin cancer, but it causes most skin cancer deaths. Melanoma is a cancer that begins in the pigment cells that produce the skin coloring (melanin) which helps protect deeper layers of the skin from the sun´s harmful rays. Detected early, melanoma is almost always curable.
Photodynamic therapy
Both nonmelanoma and melanoma skin cancers respond to photodynamic therapy (PDT). PDT is a Food and Drug Administration (FDA) approved treatment for skin cancer that combines a light source and a photosensitizing agent (a drug that is activated by light) to destroy cancer cells. It´s sometimes called photoradiation therapy, phototherapy or photochemotherapy and is useful when there are several lesions on the skin or scalp.

A photosensitizing agent, for example fluorouracil, spread on the skin makes PDT work, because the agent collects more readily in cancer cells than in normal cells. Exposing the agent to light makes it react with oxygen to create chemicals that can kill a skin cancer cell. However, the approved light sources can only penetrate a limited depth of tissue; therefore doctors mainly use PDT to treat areas on or just under the skin. It´s less effective for treating large tumors, because the light cannot pass deep into the tumors. Because it´s a localized treatment, doctors don´t use PDT to treat skin cancer that has metastasized.
Doctors sometimes use PDT in precancerous treatments. It usually needs pre-approval by a healthcare provider. Just because the treatment is in the facial area, case managers shouldn´t assume it´s a cosmetic treatment. Check to see the patient´s age, if the patient is over 60 years old, the case is probably not cosmetic. Also, look at the chart to see if there are multiple lesions on the skin or scalp, usually three or more.

Skin Cancer - A Reminder

We need to get alerted: skin cancer is the most popular cancer. Every year, more than 1,000,000 skin cancer cases are diagnosed and tens of thousands of skin cancer patients die in the U.S. alone. The number of skin cancer exceeds that of all other cancers combined. Among more than 1 million of skin cancer cases, 100,000 are melanoma, the deadliest skin cancer and there is no cure for it.
The skin cancer risk is more serious to the children because they are young and more susceptible, and they expose to more sunlight than adults due to their extensive outdoor activities. Half of the total life time exposure for an individual is received during his childhood. So special care is needed for the children.
Usually, skin cancers come years later after the subjects get exposed to too much sunlight. So just because you do not see a skin cancer right away does not mean you are free of skin cancer risk. So careful protection is the key.

Sun Exposure & UV Rays: The Basic Facts

The human body benefits from sun exposure. And a little bit of tan protects you from the sun. Right? Wrong!
The body does indeed benefit from sun exposure. But a little bit of tan does not necessarily protect you from the sun. Let’s see why.
The sun’s rays are a major source of vitamin D and help the body’s systems acquire much needed calcium for building healthy bones. However, most people don’t need to spend large amounts of time exposed to the sun in order to get their required amount of vitamin D.
In fact, the body’s health can actually suffer negative effects when it’s exposed too long to the sun’s rays, especially if it’s unprotected. Results can vary from skin and eye damage to immune system suppression and ultimately cancer, even for the young.
So let’s look at the basic facts about sun exposure.
There are three kinds of invisible ultraviolet (UV) rays in the sun that reaches earth: UVA, UVB, and UVC. When these rays come in contact with our skin, affects of UVA and UVB can be - tans, burns and other reactions (e.g. like acne and cancer).
It’s also notable that the effects of all UV rays are not the same. Depending upon the season, time of day and place on the planet in relation to the sun - (i.e. your altitude and latitude), the rays’ intensities vary. For example, during summertime, UV rays are at their strongest. Between 10 a.m. and 4 p.m., the rays are strongest. And close to the equator and at high altitudes (where air and cloud cover are less, resulting in increased harmful penetration of UV rays into the environment), the rays are also strongest.
In order to protect ourselves from the harmful UV rays, let’s look at the skin’s first defense - melanin.

Melanin is a chemical present in a variety of colors and concentrations in most people's skin that helps with defense from the sun. Melanin reacts with UV rays and absorbs them. Or rather, to be more specific, the rays act upon melanin, causing the melanin to spread out or grow, increasing its presence in response to the sun’s exposure. The result? A ‘sun tan’. The darker the skin color, the more melanin the skin has for protection. And ‘tanning’ for darker color is included here; ‘color’ does not have to refer to just the original skin color.
A word of caution…
Tanning may look great on the surface, - but the amount and length of time a person is exposed to the sun, determines the amount of possible damage. It also determines the future risk of damage that’s likely.
For example, people who are exposed to the sun in huge doses like ship crews, field workers and beach surfers, are at higher risks for skin damage than indoor workers. What happens is that when the amount of UV exposure is greater than what the skin's melanin can handle, sunburn can result. And those with lighter, fairer skin, who have less melanin, absorb less UV, suffering less protection.
Since research has shown that UV damage from the sun is the main cause of skin cancer, (with as high as 20% of some populations developing skin cancer during their lifetime), we need to take a proactive approach in relation to sun exposure to avoid harmful skin damage.
As we say colloquially here in Australia - “Slip, Slop, Slap”. (I.e. ‘Slip’ on a shirt, ‘Slop’ on a hat, ‘Slap’ on a sunscreen). Look after the skin you’ve got, because you’re the one who will be living with it!

Modifying Cells to Fight Skin Cancer?

Some scientists are making headway in the fight against skin cancer in Germany where they modified blood cells to use to attack tumor cells and wiped out the cancer in two male patients with advanced melanoma. Come again you did what? That is what they are saying, could it be true? Well, no one knows for sure yet, but if they figure out a way to make it work in all patients this could be a massive break thru indeed. Could this be the break thru that gene therapists have been longing for to fight cancer? Maybe some say.
Nevertheless this is good news, unfortunately there were 15 patients and only two were cured, but the two who were cured were Totally cured, completely as in 100% cured. Wow. Perhaps they will figure out why it works how it works and it what ratio it works so they can help everyone with advanced Melanoma?
If they can perfect this it might be used to fight advanced breast cancer, colon cancer and other common cancers, which put patients in terminal situations? Of course this also has application in life longevity efforts and other diseases like heart disease too. Melanoma does kill almost 10,000 people a year in the United States so this is a wonderful break thru and scientists are working to figure it all out. Consider this in 2006.

Skin Cancer - Do You Visit Tanning Salons?: "One of the main causes of skin cancer is exposure to harmful sun rays. If you thought that getting tanned at tanning salons was safer than the sun, please think again before visiting any salon again. Tanning beds and sunlamps are as dangerous as the sun rays.
Most of the bulbs used in the salons emit both UVA and UVB radiations that are also found in the sunlight and are responsible for both Melanoma and Nonmelonoma types of cancers. Exposure to tanning bulbs also reduces our body's ability to repair the damaged DNA, which is caused by UV radiation.
Tanning not only may cause cancers as the last damage but also prematurely ages the skin. How many of us realize that tanning is body's response to damage to the skin. every time, you get tanned , you accumulate skin damage. There is no such thing as safe tanning.
Unfortunately the cosmetic trends are pushing more women to tanning salons. More people are inviting cancer for the sake of the tanned look. Melanoma can kill if not diagnosed earlier. Unfortunately the young population is not changing its behavior about getting tanned. as they accumulate skin damage over the years, their getting affected by skin cancer at later stage of their life is increasing.
If you are one of those who believe that a tan is good and that tanning beds or sun lamps are safe, please stop using them. You are putting your life to a very painful death.

Skin Cancer and Your Responsibility: "Early treatment of skin cancer is the way to prevent death and generally most all skin cancers can be treated and or cured. Malignant Melanoma is the big killer, but if it is caught early it too is usually curable. There are three major types of skin cancer as per the Center for Disease and Control (CDC); �The three major types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma.�
If you have light skin and light features such as blond hair, red hair, blue or green eyes, or light skin you are much more susceptible to skin cancer than other folks. But also consider if you work outside all your life, then you will be at risk too. For Melanoma the most deadly type of skin cancer if not treated can be rather obvious to doctors as it will be non-symmetrical and have multiple shades of dark spots;
http://www.melanoma.com/melanoma/diagnosing/look/"
Skin Cancer; Early Treatment Wins the Game: "Skin cancer can happen to anyone and those at risk need to be smart and seek professional advice and/or early treatment. This makes sense of course but how do you know if you are at risk? Well if you work in an industry were you are exposed a lot to the sun you could be at risk.
If you get sunburns quite easily or have very light skin you would be more susceptible. Also if you have blue or green eyes or have blond or red hair you will be slightly more at risk. One of the most obvious things to think about is if you have skin cancer, which runs in your family. If you have a lot of moles you may wish to have a doctor look at them to see if they are the type that can become cancerous. Children who have had very bad skin burns in their past could be at risk as adults.
All doctors agree on one thing and that is of all the major types of skin cancer, early detection and treatment is your best chances for winning the game. So if you see spots on your skin, which are not symmetrical and growing these need to be checked out. The CDC says that;
�The three major types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Malignant melanoma causes more than 75% of all deaths from skin cancer. This disease can spread to other organs, most commonly the lungs and liver. Malignant melanoma diagnosed at an early stage usually can be cured, but melanoma diagnosed at a late stage is more likely to spread and cause death.�
For Skin Cancer; Early Treatment Wins the Game and thus ask your doctor to look at the spots on your skin to make sure they are not cancerous and keep an eye on them, be smart. Please consider all this in 2006.

Dark Green Leafy Vegetables And Dark Red Fruits Help Prevent Skin Cancer: "According to recent statistics the rising incidence of skin cancer is one of the main problems in United States. Considering that this condition appears to be becoming an epidemic, very critical is to develop new approaches to primary and secondary prevention. As consequences we can see many studies exploring the therapeutic value of natural ingredients and researches suggest that common fruit and vegetables extracts may have an important clinical benefits in lowering risk for skin cancer.

It is well-known that fruits and vegetables contain a variety of minerals and vitamins and other bioactive substances that include lutein, flavonoids, folic acid, vitamins C and E, and fiber. The folic acid has a key role in repair and synthesis of DNA, and all dark green leafy vegetables are very rich in it. So, new findings show with no doubt that higher intakes of green leafy vegetables may help prevent Squamous cell carcinoma (SCC) tumors among patients who have prior skin cancers.

Another new finding is that pigment that gives certain fruits their dark red colors has an antioxidant activity higher than that of green tea and red wine. Researchers evaluated that pomegranate fruit extract (PFE) is capable of inhibiting conventional as well as new biomarkers of TPA-induced tumors and they may have chemopreventive action in a wide category of tumor models.

Melanoma Cancer: "Melanoma is a skin disease where cancerous cells grow in the melanocytes, the cells that generate skin color. Melanoma is either known as malignant melanoma or cutaneous melanoma.
Of all types of skin cancer plaguing mankind, melanoma is considered the most serious. The epidermis, or the topmost layer of the skin, contains three types of cells liable to become cancerous. Those are squamous cells, basal cells and melanocytes. Squamous cell cancer and basal cell cancer are known as non-melanoma skin cancers. They are more widespread than melanoma. Melanoma, which is relatively less common than the other two, is indubitably more serious and complicated to treat than either squamous cell cancer or basal cell cancer.
Though it is normally found in adults, melanoma can be sporadically spotted in children and young people. The cancer generally grows in an already existing mole or a new mole that appears on the skin. Men commonly get melanomas on the area between the hips and the shoulders, the neck or the head. Women, on the other hand, contract the disease mostly on the arms of the legs. In exceptional cases, it can grow in body parts that are not covered by the skin, such as mouth, eyes, large intestines or vagina.
Melanoma can be cured if diagnosed early. Unlike other types of skin cancer, however, it can rapidly reach other parts of the body through the lymph system or the blood. Melanoma is responsible for about 80% of deaths occurring from skin cancer, although it constitutes less than 5% of all skin cancer cases. In the United States, the reported number of melanoma cases is growing alarmingly.
Melanoma provides detailed information on Melanoma, Malignant Melanoma, Melanoma Cancer, Nodular Melanoma and more. Melanoma is affiliated with Ozone Generator.
