Skin cancer health precautions?

I tan really easily, and skin cancer is common on my mother's side of the family. i put on sunscreen alot when im outside like at the pool or something. And it seems whenever i go swimming, these little moles randomly pop up on my chest. Is it anything dangerous? i've heard that anyone who has over 30 moles is at risk for skin cancer or something... Is it something I should be worried about?

Any mole can be cancerous, if a mole appears or changes in any way go straight to a dermatologist.

My personal experience and knowledge of skin cancer, if the mole is the same isometrically not a concern. Irregular shape, forms a scab then appears to heal then returns get it checked out, if also doesn't hurt to map out the moles on your body, keep track of location, any changes and measure the size.

I use 30 spf sunscreen which is on the weaker side of protection, there are so many available today there is really not excuse to not use them all the time, not just when you know you will be out in the sun.

Generally cancer itself is a precaution. Definitely keep an eye on it and make consistent visits for screenings because it is in your genes.

However, moles are common amongst everyone. The average person can have up to 20-100 moles and as they get closer to the age of 20, they will have about all of the moles that will appear throughout their lifetime. Keep in mind that any irregularity in shape, size, color, texture, or anything that seems at all suspicious, should be looked at; especially in your case. On the other hand, if you're below 20 years old, I wouldn't be as worried about it because your skin is still developing.

Either way, I would still do screenings and check ups every now and then. Good luck. =]
