The tailbone area of by buttocks has been very itchy as of late. Recently I ve been diagnosed with vitiligo, and I ve been told that there s an increased risk for skin cancer (notably for those that undergo certain treatments, like depigmenting the entire skin). Whenever I do succumb to the itch, I m unsure if I m feeling my tailbone or some new lump that may have formed. I know someone in my situation would understandably grow paranoid, but I m just wondering if this tailbone itch can be a sign of cancer. Most likely, from what I ve read, it can be something of an allergic reaction or fungal infection, but it wouldn t hurt to be sure.
