Strange lesion on arm
Hi. I am new here. I have never had skin cancer, but had Metaplastic Breast Cancer in 2009.
I am a little concerned about a lesion on my arm. I am skeptical that it is cancer because it appeared and changed within days, not sure skin cancer does that.
Anyway, a couple of days ago I noticed a small lump on my arm, raised, skin colored except for a small red spot. The next day, the red had spread to the entire lump. Then tonight, it was rough and flaky, and had a tiny scab which came right off when I barely touched it and it bled just a little.
Now it just looks like a small open sore. There was nothing there prior to all this that I can recall. Would you have it checked or just keep an eye on it for a few days. The thought of cancer again scares me to death, I'm already scheduled for a biopsy of my uterine lining next week, and now this.
