Worried about a lump on my husband"s leg. Its on the outer part of his thigh. Its grown over the past year to the size of a 1/2 dollar. My husband spends long hours on his feet as a chef. He's 52 years old and the lump now seems to cause some numbness in his leg after a few hours of standing. We have the type of insurance which permits us to directly see a specialist, bypassing a gp. Where should he start?
