I’ve had skin cancer twice and had a squamous cell on my arm removed a few years ago with Mohs surgery. It appeared another squamous cell carcinoma was growing below my skin cancer I had removed a few years ago so I went in for a biopsy a few days ago. When the dermatologist said he wanted to biopsy it, I asked him to check another spot that’s been changing over the past year. He ended up taking two biopsies and the unexpected one was for melanoma. Now I think the melanoma biopsy is getting infected because it’s getting redder and has a little pus when I clean it- I sure hope this one is benign. I think the one on my arm is another skin cancer but hoping my chest comes back benign and the infection doesn’t cause more problems. I will call the doctor if the antibiotic cream I have doesn’t help.
