question: My son had a lesion on his scalp biopsied because it was irregular in shape and color, and had grown rapidly to about 6/8" across.  The results came by "atypical melanocytic proliferation of uncertain malignant potential" and the pathologist recommended wide-excision of the remainder of the lesion.  The dermatologist wants to be more conservative and monitor it every 6 months for changes.  My son is 22 years old, has had transient increases in his liver enzymes lately, has had some weight loss (about 15 lbs - he is 6'3" and weighs 167 lbs), and has 2 enlarged lymph nodes in his neck.  I'm scared and feel a conservative approach is not the right route at this time.  Am I being too paranoid??  Thanks.
