Share to:

Could you please provide more context or details regarding your question for Dr. Hsu?


Hello, Dr.
Hsu.
I have a cauliflower-like growth inside my anus, approximately 1.5 cm in size, and I have engaged in anal intercourse (as the receptive partner) while always using a condom.
I would like to know if I have a risk of developing colorectal cancer.
I am currently undergoing treatment with Lerdaprim, and sometimes I experience intermittent pain in my lower left abdomen.
Thank you for your assistance!

Dr. Xu Weikai reply Urology


Hello, in general, if there are cauliflower-like growths near the anus, aside from local treatment, after addressing all visible lesions, an anal and rectal examination will be arranged to check for any cauliflower-like growths inside the intestines.
Even if protection was used throughout, there may still be some oversight; otherwise, how would the cauliflower-like growths occur? Therefore, if you are concerned, it is best to get tested for HIV and other sexually transmitted infections, and retest in 6-8 weeks for more accurate results.
This is a response from Dr.
Hsu Wei-Kai, Director of Urology at Taitung Hospital, Department of Health, Executive Yuan.

Understanding the relationship between anal warts and colorectal cancer is crucial for individuals who may be concerned about their health, especially those with a history of anal warts or engaging in anal intercourse. Anal warts, also known as condylomata acuminata, are caused by the human papillomavirus (HPV), a sexually transmitted infection. While HPV is known to be associated with several types of cancer, including cervical cancer and anal cancer, the connection between anal warts and colorectal cancer is less direct.

Firstly, it is important to clarify that anal warts themselves do not directly cause colorectal cancer. However, certain high-risk strains of HPV, particularly HPV types 16 and 18, are associated with an increased risk of anal cancer, which is a different entity from colorectal cancer. Anal cancer is more closely related to the presence of HPV and is more common in individuals who engage in receptive anal intercourse, especially if they have multiple sexual partners or a history of sexually transmitted infections.

Regarding your specific situation, having anal warts does not inherently increase your risk of developing colorectal cancer. Colorectal cancer is influenced by various factors, including age, family history, diet, lifestyle, and certain medical conditions. The presence of anal warts may warrant monitoring for anal cancer, particularly if there are any changes in the warts or if you experience symptoms such as bleeding, pain, or changes in bowel habits.

The left lower abdominal pain you mentioned could be related to several factors, including gastrointestinal issues, muscle strain, or even complications related to the anal warts. It is essential to discuss these symptoms with your healthcare provider, who may recommend further evaluation, such as imaging studies or a colonoscopy, to rule out any significant underlying conditions.

In terms of prevention and monitoring, it is advisable to maintain regular check-ups with your healthcare provider, especially if you have a history of HPV-related conditions. Vaccination against HPV is also recommended for eligible individuals, as it can significantly reduce the risk of developing HPV-related cancers.

In summary, while anal warts are associated with HPV and can increase the risk of anal cancer, they do not directly increase the risk of colorectal cancer. It is essential to monitor any symptoms and maintain open communication with your healthcare provider for appropriate management and screening. Regular screenings, a healthy lifestyle, and awareness of any changes in your health are key components in reducing your overall cancer risk.
