Since you have the normal pap smear, it is very less likely that the colonoscopy will find abnormal lesions. If it doesn't find them, they don't do biopsies. Here is a comment about HPV screening without pap smear. The biopsy doesn't make cancer spread. The cancer usually spreads very slowly. You can wait until you come back.
HPV infection in women ≥30 years is more likely to be persistent and, therefore, has a greater likelihood of clinical significance. However, any strategy that includes HPV screening (with or without Pap tests, or with Pap test as triage) increases the number of positive results from screening and the number of colposcopies performed; long-term outcomes remain uncertain.
A 2011 systematic review of HPV screening concluded that although primary HPV testing for women over age 30 detected more cases of CIN 3 or cancer than cytology, the evidence was insufficient to determine the net benefit of HPV testing strategies. The authors concluded that primary HPV testing was "very promising" as a screening strategy, particularly when coupled with cytology triage prior to colposcopy, but that more data are needed to determine the balance of benefits and harms from an HPV strategy, including the potential for overdiagnosis and excess colposcopy.
