(HealthDay News) -- Women tend to miss almost half their menopause-related hot flashes, which are associated with memory problems, according to a University of Illinois at Chicago study that included 29 women with moderate to severe hot flashes.

The women wore monitors that measured skin changes during a hot flash. Both subjective (self-reported) and objective (detected by the monitor) hot flashes were recorded over 24 hours. The average number of objective hot flashes was 19.5 per day, about 40 percent more than were reported by the women.

As the days get longer and the weather heats up, many people's minds turn to skin -- perhaps because they plan to show more of it in the coming months.

With that in mind, we approached a number of myths about how to help your skin look its best. Some of these are warnings you heard from your mother, while others are the type you might have heard from your friend who subscribes to 20 magazines. Some are proverbial old wives' tales, others have solid medical evidence behind them, and a few are true -- but misleading.

Hi

We just noticed a small blackish brown mole on our toddlers thigh that has appeared out of nowhere. It is dark brown in color and is quite small but noticeable. It has not changed in size or color or consistency since it sprouted but it hasn't been that long. It wasn't there a few weeks ago - this is brand new.

Does anyone know why this would happen? Is it something that needs to be seen by a doctor or is this common?

She has very fair skin and wears a factor 50 sunblock at all times and has no other moles or freckles.

Thanks
