I literally went 4 years without a diagnosis. I had a rash like prickly heat all over my legs & no physician from my primary to my dermo could figure it out. Finally, after 4 years the nurse practitioner asked if I wanted to do a biopsy. I agreed. By this point the rash was everywhere. The biopsy came back squamous cell carcinoma but was difficult to treat, as it was on my chest, face & scalp. I had chemo creams, red light/ blue light radiation, cryotherapy and Mohs. I was a mess & went through a very bad time. Luckily the cancer is now under control. I see my dermo-oncologist every 3 months & get treatment if needed. I feel so much better now! If anyone has any questions or needs some help, feel free to contact. Stay persistent, you know when something is wrong with your body until you get some peace of mind!❤️
