Mole on the sole of foot

Since I was a child I have had a mole on the bottom of my foot. It wasn't always there, but I'm not sure when exactly it formed because I don't ever feel it. If I were to guess when it formed, I would say I was around the age of 11...maybe.

Anyway, it is a round,flat brown mole and it is located in the center of the arch on the sole of my foot. It has never irritated me, so I chose to leave it (although my family doctor at the time said I should have it removed at some point...just in case). My mother had ovarian cancer, so she is very cautious of these things. She is the one who explained to me that moles on the soles of the feet or palms of the hands were dangerous. Are these types of moles very serious? Should I be concerned about this mole? It has never irritated me and I haven't noticed any distinct changes in it over the years (I am 23 now).

Also, I have a raised mole on my shoulder, which tends to itch and if I scratch it, it stings. The mole is soft and sticks out a bit. It is very dark brown in colour. Should I be more concerned with this mole than the one on my foot? The one on my shoulder tends to become irriated frequently, but that may just be from its location (the collars of my shirts sometimes rub against it).

Thank you for your time.

Please don't be concerned about either mole. Moles itch if they are irritated and it sounds like the one on your shoulder does get irritated. The one on your foot hasn't changed and this is good. It does pay to keep an eye on it though and show it to your doctor every 6 months or so.

Take care.
