Moles and Skin Cancer: The Real Story

This is an excellent article about moles and whether or not that by removing moles you can reduce the risk of melanoma. Most people know that melanoma and moles are related, but the real facts are below

Does Removing Moles Reduce the Risk of Developing Melanoma?
By Stephen Wassall


A common misconception is that removing moles reduces melanoma risk.

There is no doubt that having a lot of moles increases the risk of developing melanoma. However, melanoma experts now believe that it is impossible to predict which moles will turn malignant. In other words, we know which patients are at higher risk, but not necessarily which moles are at greatest risk.


Consider this:-
1. Many people believe that all melanomas come from moles. In fact, only around 40% of melanomas arise from moles - the rest develop in normal skin.
2. The lifetime risk of a benign mole turning into a melanoma is somewhere between 1 in 3000 to 1 in 10 000.

Therefore, the removing of benign moles is unnecessary. It has a negligible impact on reducing your melanoma risk. Even if every mole on your body was removed you would only halve your risk because 60% of melanomas don't come from moles. The lifetime risk of a woman developing breast cancer is about 1 in 14. We wouldn't consider removing breasts to reduce the risk of cancer. Why would we remove a mole that has a risk of 1 in 3000 or less?


Dysplastic Moles
There is a type of mole known as a dysplastic mole which deserves special consideration. Dysplastic moles tend to be larger and more irregular than most moles. About 20% of the population will have one or more of these moles. Traditionally dysplastic moles were considered to be at higher risk of turning into melanoma. However, recent studies have suggested that the lifetime risk of a dysplastic mole becoming a melanoma is less than 1 in 1000.

There is good evidence that people who have more than 5 dysplastic moles are at higher risk of developing melanoma. However, that is not to say that it will necessarily be one of the dysplastic moles which will turn into melanoma. Melanoma experts now believe that people with multiple dysplastic moles have a predisposition to abnormal melanin production in their skin which increases the risk of developing melanoma at any site - not just within the dysplastic moles. Removing the dysplastic moles has a small impact on reducing risk of melanoma.

In reality, melanoma diagnosis is a skill that can only be developed with expertise and experience. Various factors need to be taken into consideration eg. recent change in a mole, previous history of melanoma or a family history. In addition, many people have a particular type of mole pattern - almost like a fingerprint. A particular type of mole may look perfectly benign and normal on one patient and totally out of place on another. Therefore, the decision to remove a mole is based on many variables.

However, the facts still remain. There should be a good clinical reason to remove a mole. Mole removal does have potential complications such as bleeding, infection and significant scarring.


Recommendations


In summary, my recommendations are as follows:
1. People at risk should have an annual skin check.
2. After a thorough examination moles which have diagnostic criteria for melanoma are removed. In skilled hands, 92% of melanomas can be diagnosed on initial examination.
3. Suspicious moles with no definite features of melanoma should be photographed and rechecked in 3 months. If they change they are removed. This includes moles that the patient has noticed change in but look benign clinically.
4. People with multiple dysplastic moles should be checked every 6 months and have long-term photographing and monitoring of their suspicious moles.

Indoor tanning linked to anxiety, substance abuse

Indoor tanning linked to anxiety, substance abuse

A study published by the Archives of Dermatology showed a correlation between indoor tanning and addiction, suggesting that those who frequent tanning beds show tendencies to use alcohol and marijuana.

The popular fashion statement of bronzed skin is a growing trend these days, researchers have found this golden-fried look can lead to a dangerous indoor tanning addiction.

A recent study published in the April edition of Archives of Dermatology suggested that people who frequently use indoor tanning beds also have more tendencies to use alcohol and marijuana than those who do not.

Thirty-nine percent of the students surveyed who have tanned indoors showed signs of having an addiction to tanning. Students who showed addictive tendencies to indoor tanning also showed a greater use of alcohol and marijuana.

More than 400 college students from a university in the northeastern part of the country participated in a month-long study assessing the correlation between addiction and indoor tanning. Each participant filled out a questionnaire that included questions about their demographics, frequency of indoor tanning and how often they use substances like tobacco, alcohol and marijuana. After completing the questionnaire, each participant was screened for alcoholism and substance-related disorders. The participants also participated in a self-evaluation measuring their levels of anxiety and depression.

“I think indoor tanning is dumb, “ said Allyson Lewis, an education freshman. “It’s obviously not real and it’s more dangerous. People fake and bake because it’s faster and easier. I think people can become addicted to tanning just like they can become addicted to shopping.”

When asked how Lewis maintains her luminous glow, she replied, “I don’t go tanning, I lay out. I like saying that it’s all natural. It’s like getting fake boobs, no one wants to admit that it’s not real.”

Drs. Catherine E. Mosher, of Memorial Sloan-Kettering Cancer Center, and Sharon Danoff-Burg of the State University at Albany in New York, administered the study. They used the Cut Down, Annoyed, Guilty, Eye-opener method and the Diagnostic and Statistical Manual of Mental Disorders to create criteria for addiction. These methods are commonly used in the medical and psychological fields to diagnose an individual with anxiety, depression or other substance-related disorders.

Researchers hypothesized that frequent exposure to UV light results in a behavioral pattern related to alcoholism and substance abuse. Other studies on UV light have determined it enables relaxation, improved moods and increased socialization. These effects of tanning can fuel students’ desire for more indoor tanning.

Heather Hiscox, a program development coordinator at the Skin Cancer Institute at the Arizona Cancer Center, said, “People that tan before the age of 30 have a 70 percent increased chance of getting melanoma skin cancer.”

Hiscox did not want to comment on the behavioral issues associated with the study because she did not have the time to fully read the study.

“I’ve worked with people that knew tanning was putting them at risk and they still could not stop,” she said. “The results and data are very interesting.”

Two workers from Hollywood Tans, a tanning salon located on University Boulevard, refused to comment because company policy dictates that workers are not allowed to speak to the press.

Researchers suggest that skin cancer interventions inform these “tanorexic” individuals of the addictive qualities of indoor tanning and the correlation to substance-related disorders.

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. Protect yourself and your family from skin cancer while enjoying the outdoors.

Self Examination for Signs of Skin Cancer

It is very easy to give yourself an examination for signs of skin cancer. Develop a routine to regularly inspect your body for skin growth changes. If any growth, mole, sore or skin discoloration begins to change or suddenly appears, see your dermatologist. Remember, each of the skin cancers are treatable with early detection.
To help you know waht to look for, there is an easy reminder of what to look for in the exam. It is the ABCD’s and recently added E. The letters stand for:

Asymmetry - when one half of the growth has a different shape than the other.

Border irregular - when the growth has uneven edges

Color varied – the growth has more than one color. Melanomas may be black, shades of brown and tan, and even have specks of red, white, blue or/and black.

Diameter - a size, bigger than the diameter of a pencil eraser.

Enlargement - recently doctors haves have recognized the importance of moles that grow larger in predicting high-risk lesions. Thus they have now added E to the criteria.

Remember, with early detection, skin cancer is not only treatable, but also curable. I recently read an excellent ebook. "How I Survived Melanoma Skin Cancer - seven survivors tell their stories" It is written from the vantage point of 7 people diagnosed with Skin Cancer. I was impressed most not with the clinical information that you find on most websites, but with the emotional and mental attitude of these survivors. They share their stories on how they keep positive even at the lowest moments. It really is a good read. I read things that I hadn’t found anywhere else. A recommended read for dark nights.
