HACKED BY CYBER-ATTACK - ALPERENBTN

[Big John]

As angler we spend alot of time in the sun, with double exposure from reflections off the sand and water. This proves an interesting read from Reuters.


By Anthony J. Brown, MD
NEW YORK (Reuters Health) - Two new studies suggest that exposure to sunlight might not be as risky for cancer as is generally believed.

Scandinavian researchers show that high UV radiation exposure is associated with a reduced risk of lymphoma, while another team reports that sunlight-related melanoma skin cancers appear to be inherently less aggressive than those that arise in non-exposed areas.

Dr. Karin Elkstrom Smedby, from the Karolinska Institute in Stockholm, and colleagues investigated ultraviolet radiation exposure as a possible cause for the increasing rates of malignant lymphoma seen in recent decades.

Instead, the researchers found that high UV radiation exposure, as measured by frequent sunbathing and sunburns, cut the risk of the non-Hogkins type of lymphoma by up to 40 percent depending on the level of exposure.

The study involved 3740 patients with malignant lymphomas who were compared with 3187 matched "controls" from the general population. High UV radiation exposure also seemed to protect again the Hodgkin's type of lymphoma, but the association was weaker than with non-Hodgkin's disease.

In another study, also reported in the Journal of the National Cancer Institute, researchers note that sun exposure has been linked to better survival in patients with melanoma. The new research suggests that this is due, at least in part, to sunlight-related tumors being inherently less aggressive than those not tied to sun exposure.

"Our findings provide the strongest evidence to date that the better prognosis of (sunlight-related) melanomas is not simply due to earlier detection of these types," Dr. Marianne Berwick told Reuters Health.

Berwick, a researcher from the University of New Mexico in Albuquerque, noted that "further studies are needed to determine how sun exposure might reduce melanoma aggressiveness," but said that it could have something to do with increased production of vitamin D, or involve an enhanced ability of cells to repair DNA damage.

The findings stem from a study of 528 melanoma patients who were entered in the Connecticut Tumor Registry.

Sunburn, high intermittent sun exposure, self-reported skin awareness, and solar elastosis -- a marker of sun damaged-skin -- were all linked to increased survival from melanoma.

Upon analysis, skin awareness was a strong predictor of better survival, consistent with the belief that earlier detection leads to better outcomes. However, solar elastosis, which does not relate to detection, was found to be an even stronger predictor of increased survival.

Berwick emphasized that these findings have no bearing on current recommendations that "avoiding sun exposure reduces the risk of melanoma." Moreover, she added that they also do not suggest that exposing melanomas to sunlight after they've developed will improve survival.

Man, things are really improving. First they said beer is good for your heart and now major sun exposure is good for cancer. I might just be bullet proof!

It has been reported by more than a few eggheads with a PhD, that smokers who have colds remain ill twice as long as non-smokers. I'd like to see a double-blind study concerning the effects of inhaled smoke among chain-smokers, to find if all the carcinogens, additives and other poisons inherent in the smoke ward off such an illness; and the average number of colds and flu(s) effecting both groups over a given period of time, as a direct result of puffing, or not puffing.

A funny site, with supporting "evidences" milk and meat is B-A-D for humans ---> http://www.notmilk.com (It's amusing people are so politically-correct in society, that they won't point out evolutionary differences between separate gene populations. For example, people of Northern European descent are generally not lactose intolerant, whereas much of the rest of the earth's other folk are.)

Milk and meat is good for you! ----> http://www.biblelife.org/beef.htm ( A hard hitting rebuttal to the anti-meat, fur-hugging, "fish have feelings, too" people out there! )

Everyone has "studies" to back up their claims. It takes a cautious, objective and keenly trained eye to separate the quacks from the honest researchers:

http://www.quackwatch.com (Remember the claims of Dr. Bob Barefoot? He touted the benefits of coral calcium on numerous television info-mercials over the past couple years. This site lacerates the claims made by this charlatan. ) Enjoy!

There are also studies that show that there are more cases of diabetes in the north like Canada and northern Europe because they get less sun that we do farther south. I am sure it is like anything else as long as it is done in moderation you are okay.

Actually, according to study, the markers of high sun exposure - ie: sunburn, and wrinkles are what point to a higher survival rate from skin cancer.

"Sunburn, high intermittent sun exposure, self-reported skin awareness, and solar elastosis -- a marker of sun damaged-skin -- were all linked to increased survival from melanoma."

I did a little more digging on this, and on person who constantly were in the sun, those areas that were not exposed, ie. under a shirt or shorts, show more serious melanomas than the exposed areas.

Very interesting.

I am still waiting for them to find that the kitchen sink causes cancer.

Back when I used to be a greek god and ran around shirtless baking in the sun to get that golden brown tan, I thought it looked great! Also being olive skinned I thought I was immune to skin cancer but lo and behold two years ago I got a malignant melanoma on my ear. They reamed it out with sort of a melon baller and got all of it but not before they phoned me and suggested that I get a chest x-ray and blood test the next day to determine if the cancer had spread. Pretty scary stuff. Bottom line is to wear sunscreen and long sleeved shirts if possible. Also protect your eyes as sun exposure has been linked to cataracts.

The alternative heath folks have long taughted the need for full body exposure to the sun. There is a marked increase in prostate cancer in northern areas than there is in southern areas. God made us naked. Maybe he meant it?
