red spot on leg, biopsy

I am terrified to even ask this question.  I am a nervous wreck.  I am 52, female, fair skin, freckles. I had several bad sunburns when I was young but careful ever since.  I have had this red, flat spot on my lower leg for I am guessing about 10 months.  It did not change color or size (as far as I can tell), approximately a pencil eraser, and did not bother me at all.  I thought it was a blood vessel or just sun damage on my fair skin, which looks reddish at times, not a mole.  I can't believe I ignored it, but it just did not look scary to me since it wasn't dark or bleeding.

I have (new) sunspots and have had skin tags, which also brought me to the dermatologist (way too young) a few days ago and also to check the red spot.  She froze two spots on my chest, not too big a deal.  She seemed alarmed at the red spot and did a shave biopsy. When I asked why she didn't do a punch biopsy or excision, she said that it was a bit scaly but not a dark color.  I thought that if a spot seemed dangerous, a doctor would just take it out right away and not do a shave.

I have since read that it is unwise to do a shave biopsy on suspected melanoma because of the depth or stage. I called the next day to ask that, and she said they could find cancer cells with a shave only, and she is not overly concerned, but she sounded concerned.  She is also very young.  Anyway, the biopsy seems to be healing, am following instructions - it went from pinkish red, now back to all red like it looked before the shave. Is that bad??  I know lower leg is not a good spot, either.  Anyone have a comment?  I have to wait a week and am going away to a wedding next Thursday, and don't want to be a damper.  Thank you!!
