3 new scars... Update - Big Relief.

Regular dermatological checkups are a must, especially if you've spent a good deal in the sun. If they catch a melanoma early then it's generally not a problem, they may also determine that something is "pre-cancerous" which means it's fine now but you're advised to have it removed before it turns bad.
 
I had one 7 or 8 years ago, a dark black mole on my upper arm which was irregular shaped. People kept asking me if it was a bug. I put off having it checked out for ages but it's a good job I eventually did because it turned out to be malignant and the specialist said that if I'd left it another 6 weeks it could have gotten into my lymph system. I think it was stage 6 or something like that. The worst of it was I was uninsured so it ended up costing me thousands of dollars, although when you're paying upfront in cash it's usually possible to negotiate the surgeon's fee right down, which I successfully did. Anyway they took a big chunk of flesh out of my arm and sewed it up perfectly so you'd never know apart from a very feint scar.
 
I think the first 2 years I had to have dermatological checkup every 3 months, and then even since it's been every 6 months. You'll be fine as long as you get them checked out regularly and go forward with any necessary treatment as soon as possible. They don't sound like melanomas to me although to be honest I'm no expert apart from my own narrow experience.

I hope you're OK.
