Tanning beds still popular despite skin cancer risk

Tanning beds still popular despite skin cancer riskWashington, Dec 21: A new study has revealed that few tanners-male or female-mention avoiding tanning beds when asked about ways to reduce skin cancer risk.

The study also suggested that women are more likely to report use of indoor tanning facilities than men, and some characteristics common to indoor tanners differ by sex.

Skin cancer death toll soars three-fold among pensioners

Skin cancer death toll soars three-fold among pensionersLondon, Nov 30 : Pensioners in Britain are three times more likely to die of skin cancer compared to 30 years ago. The reason - cheap package holidays to countries such as Spain, Portugal and Greece.

The number of over-65s being diagnosed with malignant melanoma has risen by five times in the past 30 years and they are more at risk than any other age group.

Can skin cancer be treated with light?

Can skin cancer be treated with light?Washington, Oct 19 : Researchers at the University of California, Irvine, are exploring new ways to image cancerous lesions using LEDs that might advance a technique for treating cancer called photodynamic therapy (PDT).

In PDT, photosensitizing chemicals that absorb light are injected into a tumor, which is then exposed to light. The chemicals generate oxygen radicals from the light energy, destroying the cancer cells.

Vigilance against skin cancer may lead to vitamin D deficiency

 Vigilance against skin cancer may lead to vitamin D deficiencyWashington, Oct 19 : A new study has suggested that vigilance against skin cancer can cause vitamin D deficiency.

Patients with basal cell nevus syndrome-which might lead to non-melanoma skin cancers-are at a higher risk for vitamin D deficiency if they take steps to protect themselves from sunlight.

''Co-conspirator'' cells may hold key to skin cancer prevention

Skin CancerWashington, Aug 31 : A new research has identified cancer cells called ''co-conspirator'' in the genesis of melanoma - a finding that could be the key to predicting and preventing skin cancer.

Apart from the body''s pigment-producing cells where melanoma takes hold, other skin cells in what''s called the "microenvironment" of the cancer site also play a key role, Oregon State University scientists said.

'Go Greek'' with foods to prevent skin cancer

'Go Greek'' with foods to prevent skin cancerWashington, Aug 17 : Love basking in the sun, but scared of those harmful sunrays? Well, now there’s a safer way to make fun in the sun safer—stick to a Mediterranean diet.

Dr. Niva Shapira of Tel Aviv University''s School of Health Professions has shown that a diet rich in antioxidants and omega-3 fatty acids, like the diet eaten in Mediterranean regions where melanoma rates are extremely low, can help protect us from skin cancer.

Sunscreens containing vitamin A do not cause skin cancer: Study

 Sunscreens containing vitamin A do not cause skin cancer: StudyWashington, Aug 11 : There is no evidence that the inclusion of retinyl palmitate (vitamin A) in sunscreens can cause cancer in humans, according to a new study.

"Earlier this year, the Environmental Working Group issued a health warning that sunscreens containing retinyl palmitate could pose a cancer risk," said dermatologist Henry W. Lim of Henry Ford Hospital.

Teenagers using sunbeds may develop deadly skin cancer

Skin CancerLondon, Aug 2 : A new research has revealed that teenagers who use sunbeds almost double their chances of developing the deadliest form of skin cancer.

Those who recurrently use UV booths are nearly twice as likely to develop a life-threatening melanoma, reports the Daily Express.

And the earlier that sunbed usage begins, the greater the risk of developing a cancerous tumour before 40.

New way to slow growth of deadly skin cancer

 New way to slow growth of deadly skin cancerWashington, July 9 : Scientists at Queen''s University have demonstrated that the growth of melanoma, one of the most deadly forms of skin cancer, can be slowed when a little known gene called MicroRNA
193b is added.

Victor Tron, head of pathology and molecular medicine, focused on miR-193b when he discovered that it was deficient in melanoma tumors and because there were very few studies done about the gene.

HPV infection ‘increases skin cancer risk’

London, July 9 : An international team of researchers has found that HPV infection heightens the risk of developing certain skin cancers and is worsened if people are taking immunosuppression drugs.

During the study, they found that people with several types of human papillomaviruses (HPVs) were more than one and a half times as likely to develop certain skin cancers compared to people with no HPVs.

Combination of chemotherapies not effective for melanoma patients

Combination of chemotherapies not effective for melanoma patientsAccording to a new study, the combination of two different chemotherapies and a previously approved treatment for kidney and liver cancers is not effective against advanced melanoma, a rare form of skin cancer.

People think their skin is darker than it is

People think their skin is darker than it isSydney, May 18 : People tend to overestimate the darkness of their natural, non-tanned skin.

The researchers identifying the pattern have called it "the dark shift" and believe it may have important implications for how well skin cancer risk messages are heeded.

The findings are based on a study involving nearly 300 University of Otago students.

New research could help open ways to shrink skin cancers

Washington, Jan 18 - Most skin cancers are curable, but require surgery that can be painful and scarring, says a new study whose findings could open up ways to newer treatments that would shrink skin cancer tumours.

The drugs would work by turning on a gene that prevents skin cells from becoming cancerous, said senior study author Mitchell Denning, pathology professor at the Loyola University Chicago Stritch School of Medicine (LUCSSM).

The study was done by researchers of the Loyola University Health System (LUHS).

Chronic inflammation may help prevent skin cancer

Washington, Oct 22 : Studying an animal model of chronic inflammation and skin cancer, scientists have now found that inflammation can actually prevent skin cancer.

Inflammation is the frontline defence of the body against infection or disease.

According to researchers at Medical College of Georgia, IDO, an enzyme that works like a firefighter to keep inflammation under control, can be captured to protect early malignant cells

Scientists sniff out the ‘scent’ of skin cancer

Scientists sniff out the ‘scent’ of skin cancerWashington, Aug 21 : Odors from skin can be used to identify basal cell carcinoma, the most common form of skin cancer, according to a new research from the Monell Center.

The findings, presented at the 236th meeting of the American Chemical Society, may open doors to development of new methods to detect basal cell carcinoma and other forms of skin cancer.

Moisturisers can up skin cancer risk

Moisturisers can up skin cancer riskLondon, Aug 14 : Moisturisers may increase the risk of common skin cancers, according to a group of researchers.

Most of the mosturisers have never been tested for their cancer-causing effect on the skin.

But, researchers have found that they increase the carcinogenic effect of sunlight in mice.

New device can tell which moles can trigger skin cancer

London, Aug 4 : Scared if that mole on your face could one day turn out to be skin cancer? Well, then Molemate is sure to allay your fears.

Molemate is a non-invasive, rapid and painless mole-screening device that can enable a medical practitioner to quickly scan one’s moles.

It may make it possible to detect the early stages of skin cancer by allowing doctors to screen and evaluate a mole within seconds.

Based on their observations, the doctors may either reassure patients that their moles are harmless or refer them on to a specialist.

Study gives new insight into protein that keeps skin cancer in check

Washington, July 11 : Researchers at Oregon Health & Science University, Portland, have shed new light on the role of the signaling molecule Smad2 in skin cancer.

Xiao-Jing Wang and colleagues from the university provided the new insights by analysing human skin cancer tissue and a mouse model of skin cancer.

In the study, human squamous cell skin cancer samples were found to frequently lose expression of Smad2.

In particular, Smad2 expression was lost in all samples characterized as ''poorly differentiated'' (which means they had progressed to become aggressive tumours).

Skin cancer patient ‘cured’ using cloned cells

London, June 19 : A team of US researchers claims to have successfully treated a skin cancer patient with cells cloned from his own immune system.

Researchers at the Fred Hutchinson Cancer Research Center in Seattle took cancer-fighting immune cells, made five billion copies, then put them all back.

The 52-year-old patient was free of his advanced melanoma two years after the groundbreaking treatment.

During the treatment, researchers concentrated on a type of white blood cell called a CD4+ T cell.

Pimple that won't heal could be skin cancer

Euskirchen, Germany  - Pimple that won't heal could be skin cancerSomeone with a change in the skin such as a rough patch or pimple that will not heal should see a dermatologist as soon as possible.

Skin cancer leaves no scars when treated on time

Bonn  - Skin cancer leaves no scars when treated on timeSkin cancer is one of the most common forms of the disease and in Germany alone 2,700 people die of it. However, if recognized early enough and treated, it can often be cured.

Ultra violet (UV) rays remain the main risk factor, whether they come from a tanning salon or the sun. But the danger also is influenced by a person's skin type.
