Okay, so the other day I was messing around with this idea – could I actually tell the difference between a regular sun spot and something, you know, more serious? I mean, we all get those little brown spots, especially if you’re like me and love spending time outdoors. But skin cancer is a real thing, and I wanted to see if I could get a better handle on spotting the difference myself.
My Little Experiment
First, I grabbed my phone and started snapping pictures of any and all spots I could find on my arms and legs. I’ve got a bunch, thanks to years of playing sports and generally being a sun worshiper. I made sure to get good lighting – no blurry pics allowed! – and I took shots from different angles, just to be thorough.
Then, I jumped onto my computer. I started searching online. I just typed in stuff like “sun spots vs skin cancer images” and “how to tell the difference between sun spots and cancer”. I wanted to see a comparison in image, to be more clear.
After I felt like I had a decent grasp on the visual differences, I went back to my photos. I opened them up on my big monitor, side-by-side with some of the reference images I’d found. I started comparing, really looking closely at each spot.
- I paid attention to the edges. Were they smooth and round, like most of the sun spot examples? Or were they jagged, irregular, or kind of blurry?
- I looked at the color. Was it a uniform brown, or were there different shades, maybe even some red, black, or blue mixed in?
- I considered the size. Most of my spots were pretty small, but I kept an eye out for anything that seemed larger than a pencil eraser.
- I also thought about whether any of the spots had changed recently. Had they grown, changed color, started itching, or anything like that?
It was actually kind of tricky! Some of my spots were easy – definitely just sun spots. But a couple were a little less clear. They weren’t super obvious, but they had some slight irregularities that made me pause.
So, after all this, what did I actually do? Well, I decided to make an appointment with my doctor. I figured, even if it’s nothing, it’s better to be safe than sorry. And honestly, looking at those pictures and doing that comparison made me realize I should be paying more attention to my skin anyway.

The whole process was a good reminder that, while I can do some basic checks myself, I’m definitely not a dermatologist. It’s always best to leave the final diagnosis to the professionals. But hey, at least now I feel a little more informed and a little more proactive about checking my own skin!
