Spouses boost early melanoma detection

CHICAGO — There’s an extra bonus to marriage for melanoma patients: They tend to be diagnosed in earlier more treatable stages than patients who are single, a new study says.

Spouses may notice suspicious moles on their partners that could signal melanoma, the most dangerous type of skin cancer.

They may also nag their partners to get those moles checked out, researchers said.

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

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 U.S. government cancer database who were diagnosed from 2010 to 2014.

Melanoma is more likely than other skin cancers to spread beyond the initial tumour site to other organs, but all the patients had localized disease.

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

Just three per cent of married participants had the most ominous tumours compared with almost 10 per cent 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.

Melanoma often looks like a misshapen mole, with a diameter larger than a pencil eraser and can be a blend of black, brown, tan or even bluish pigment. It’s linked with too much exposure to sun or tanning beds. It’s also more common in fairskinned people and those with lots of moles.

The American Cancer Society estimates that about 90,000 U.S. cases will be diagnosed this year.
