Examine your nails for signs of melanoma.

The American Academy of Dermatology (AAD) is urging people to check their skin and nails for cancer signs. Under and around the fingernails and toenails, melanoma can develop. According to the AAD, it frequently manifests itself on the thumb or big toe of your dominant hand or foot.

A brown or black streak beneath the nail, a bump or nodule beneath the nail, the darker skin around the nail, a nail that is lifting and pulling away from the nail bed, or a split down the middle of the nail are all signs of melanoma in and around the nails. Melanoma becomes more prevalent as people age, but it is highly treatable if detected early.

This research is still being watched.
