I hope not because I have probably SOLAR urticaria....
Hi,
There had been many studies of finding the relationship of (chronic) urticaria and cancer. Results show however, that there is no significant relationship.( ref: http://www.cutis.is/Greinasafn/assets/Urticaria.pdf). However, it is very important that the triggers be identified to prevent future outbreaks.
Take care and regards.
