Weight loss surgery reduces skin cancer risk

According to a recent study, individuals with obesity who undergo weight loss surgery have a reduced risk of developing skin cancer, including melanoma.

Skin cancer is the most common form of cancer in the United States.

Melanoma accounts for just 1% of skin cancer cases, but it causes the majority of deaths from this type of disease.

There are an estimated 96,480 new melanoma diagnoses each year in the United States, and according to the authors of a recent study, the rates of malignant melanoma are rising faster than those of any other cancer.

In the U.S. there were 8,650 deaths due to melanoma in 2009 — and despite improved treatments and better 5-year survival rates, there were around 10,130 deaths from this cause in 2016.

Although scientists have identified risk factors associated with melanoma, such as fair skin, family history, and sun exposure, it is not clear why incidence rates are rising.

Because obesity is a risk factor for certain cancers, some researchers have asked whether it might also raise melanoma risk. However, to date, studies have failed to find a clear-cut association.

Revisiting old data

A Swedish study from 2009 found that women with obesity who undergo bariatric surgery have a reduced risk of cancer. When the results were published, there was not enough data to assess whether weight loss surgery impacted skin cancer risk, specifically.
