HI I am new.  I have squamous cell carcinoma . I am age 61.  My last treatment session of chemo tablets and radiotheraphy ended in July 2019.  Has any other patients experienced colour changes to their skin and extra freckles, pale blemishes to arms and legs. I am really worried a dark brown small freckle has appeared on my shoulder blade and now become itchy. my husband checked and described as a dark brown raised spot. Is this anything to worry about.
