About 6 weeks ago,I noticed a small dry patch on my jawline about 2 inches away from my ear.It seemed to shrink and harden and then I picked it off because it was annoying me,within a few days the dry patch had returned which again turned into a scab.The scab peels away easily from the edges but the centre does not want to come away.It does not bleed,itch and there is only 1scab.I have tried not to pick at it,but when I am uptight it becomes a habit and dont realise that I am doing it.I am healthy apart fro having thyroid problems 2 years ago,now treated.I am getting very woried about it,since I read an article about skin cancer.I hate sunbathing,and avoid the sun as much as possible.Please help me stop worying!!!!
