Is cancer-related, direct-to-consumer advertising beneficial?—No.
In the current communications era, cancer medications, cancer-related genetic testing, and even cancer centers are often marketed directly to the public. While there is little evidence so far that it generates inappropriate treatment recommendations in oncology,1 cancer-related, direct-to-consumer advertising (CR-DTCA) is prone to cause harm in many other ways. These include potentially fostering patient misinterpretations of expected efficacy and toxic effects of drugs with concomitant harm to the patient-physician therapeutic relationship; encouraging patient interest in new drugs when their toxic effects are not fully appreciated; and failing to present alternative treatment approaches that may be less toxic or costly.
