Cancerphobia, an intense and disproportionate fear of developing cancer, can have a profound impact on the affected individual’s daily life. Those with cancerphobia may firmly believe that symptoms such as headaches, skin issues, constipation, or difficulty swallowing are indicative of cancer. In an effort to mitigate the perceived risk of cancer, individuals may adopt behaviors resembling those seen in obsessive-compulsive disorder, such as engaging in prolonged washing rituals. Psychotherapy, including behavior therapy, holds promise as a beneficial approach for addressing this condition.
