Quick Summary

Doctors at the University of California, Irvine have identified a condition in long-time surfers characterized by fatty growths on their chests, dubbed “liposurfomas.” These growths develop from years of repeatedly pressing the chest against hard surfboards while paddling. The study involved seven surfers and found that although the lumps can resemble tumors, they are generally benign but may grow with continued surfing activity.

Story summary

Doctors in California have identified "liposurfomas," strange fatty growths on the chests of long-time surfers. These benign but alarming lumps, often mistaken for tumors due to their appearance, form after years of repeated friction between a surfer’s torso and hard surfboards during paddling. Researchers at University of California, Irvine, studying seven affected surfers, found that these growths can grow larger with continued surfing and may lead healthy surfers through unnecessary cancer tests and treatments. Dr. Jeffrey Klein, a dermatology professor at UC Irvine involved in the research, noted that such lesions are common among surfers in Southern California.
