I started smoking the pipe about 1 month ago and to my dismay I have contracted Leukoplakia which are growths of protein in the mouth with occur primarily as a result of pipe smoking. In my case it presents itself as a white spot on the side of the tongue and according to my physician a biopsy will have to be performed to analyse its possible malignancy (apparently rare) and then it will most probably have to be removed. Has anybody else encountered anything similar? Is this the end of my short pipe smoking excursion? I never had this problem with Cigars, will I have to give up those too? I am not a regular smoker so giving up completely will not be a major problem but it would be very sad if I had to give it up altogether.
