Spouses can boost early detection for melanoma patients

‘Artificial mole’ could warn of cancer: study

CHICAGO, April 19, (Agencies): There’s an extra bonus to marriage for melanoma patients: They tend to be diagnosed in earlier more treatable stages than patients who are unmarried, widowed or divorced, a new study says.

Spouses may be apt to notice suspicious moles on their partners that could signal melanoma, the most dangerous type skin cancer. More importantly, they may also be more inclined to nag their partners to get those moles checked out, the researchers said.

The findings suggest that unmarried people should ask relatives or friends to do skin checks or seek frequent skin exams with dermatologists.

Why marriage might a difference in diagnosis isn’t clear since unmarried partners or observant friends might also notice skin changes. But maybe married people have more opportunities to notice or feel more of a responsibility to keep their partners healthy, said study co-authors Cimarron Sharon and Dr Giorgos Karakousis of the University of Pennsylvania.

Researchers analyzed 52,000 melanoma patients in a US government cancer database who were diagnosed from 2010 to 2014. Melanoma is more likely than other skin cancers to spread beyond the initial tumor site to other organs, but all the patients had localized disease.

Among married patients studied, almost 47 percent had the smallest, earliest-stage tumors compared with 43 percent of never-married patients, 39 percent of divorced patients and 32 percent of widowed patients.

Just 3 percent of married participants had the most ominous tumors compared with almost 10 percent of widowed patients. Married patients also were more likely than the others to receive biopsies of nearby lymph nodes, usually recommended to guide treatment.

The study, published Wednesday in JAMA Dermatology, echoes previous research that found advanced melanoma that has spread is less common in married patients.

Swiss scientists have developed an experimental skin implant that darkens like a mole when it detects subtle changes in the body that may be an early warning sign of cancer, a study said Wednesday.

The implant, or “biomedical tattoo,” as researchers call it, has been tested in lab animals, lasts about a year and recognizes the four most common types of cancer: prostate, lung, colon and breast cancer.

It works by reacting to the level of calcium in the blood, which rises when a tumor is developing. About 40 percent of cancers could theoretically be detected this way, researchers said.

“The biomedical tattoo detects all hypercalcemic cancers at a very early, asymptomatic stage,” lead author Martin Fussenegger, Professor at the Department of Biosystems Science and Engineering at ETH Zurich, told AFP by email.

Miami is at risk of a deadly yellow fever outbreak because the disease could thrive there but the city has no checks on travellers arriving from endemic zones, a study to be published by the World Health Organization showed.

Yellow fever is spread by the same mosquito that causes Zika virus, which spread through the Americas after being detected in Brazil in 2015 and has been reported in southern Florida and southern Texas.
