Here's my story, for anyone interested. I have had 30+ non malignant moles removed from my body, including 10 on my face. This is because when pregnant, they grew quickly and became a huge problem, catching on clothes then bleeding. After pregnancy, the remain much bigger and would grow again at the next.
I am old enough that sunscreen wasn't around when I was a child, and every year I suffered horrendous sunburn because I have very fair skin and blue eyes. It used to irritate my parents because they had far better sun tolerance and thought that I was "too pale". I was always being sent to play in the sun.
As I had medical insurance at the time, removal was all done privately (in batches of 10 with local anaesthetics and stitches), but my initial appointment was a lengthy consultation with a consultant dermatologist. He identified correctly, that as a child I wore a seersucker swimming costume - we all did in those days. Every one of the moles was in an area exposed by the costume.
He told me that moles are hereditary and develop when a baby is in utero. Most of us have them. It is only sun exposure that makes them grow and become visible, although pregnancy and the associated increased blood supply can make existing moles grow too. (My children are now in their 30s. I always used factor 50 on them and covered them up in the sun too. Tshirts/wetsuits when swimming. They do not have moles and have few freckles.
Freckles, as most of us know, are a sign of sun damage which can be observed on children. When I saw the Dr, I was plastered in them, particularly my face. You could hardly put a pin between them. Since I became diligent about factor 50 suncream on my face, they have faded considerably. They are hardly noticeable but are still there.
Sun damage is far more than skin cancer. UVA rays don't burn the skin, but damage the skin as badly as the burning UVB rays. Sun related aging skin is real, as are sun related cataracts.
Please everyone, protect your children's delicate skin from the sun. Normalise covering up and playing in the shade. Use high factor sunscreen on them, particularly in the summer months and before they go to school in the morning. Yes, they hate it, but they will thank you when they are older.
