Newly Diagnosed PT1A Melanoma

I found out on the 13th Feb 2026 that I have/had pt1a Melanoma on my right breast. I had the first excision on 15th December last year. I am currently waiting on the appointment to go for my second excision. Now, I do feel so grateful because the doctor said that they most likely got it all and they are doing further excision just to be sure but I can’t help feeling bad about it. He said I basically survived cancer but all I can think about is, what if it comes back. He said it’s a very low chance with my type of cancer but to me, there is still a chance. I also have to go for an ultrasound on my armpits. When I went to my diagnosis appointment, they did a full body check and obviously felt my lymph nodes. Unfortunately, a few days before I noticed a sore lump on my left armpit. I’m pretty sure it’s just an ingrown hair because I have been having them on and off for the past couple of weeks and I think I’ve just been silly shaving so much and using a dull blade. Yesterday, I started feeling a lump in my right armpit which has now turned into 3 separate lumps. I’m trying not to freak out but I can’t help but think what if the cancer isn’t gone and it’s spreading and spreading quick. Just bare in mind, I also have been diagnosed (in the past) with severe health anxiety. Am I being paranoid or is this something I should worry about? Also, I’ve tried to stay positive but I’ve seen so many things on social media saying that melanoma is the deadliest skin cancer, how am I supposed to live my life when all I see is negative things about melanoma?
