“CA” may indicate cancer or warts. Both tumors and warts require aggressive treatment. CA can be an abbreviation for cancer. Currently, there are various treatments for cancer, including surgical removal, radiotherapy, and targeted drug therapy. However, aggressive intervention after detection usually improves the prognosis. CA may also be condyloma acuminatum, which is mostly seen in patients with human papillomavirus infection and manifests as flaky or cauliflower-shaped red papules on the genitals and around the anus, accompanied by pain and itching on the local skin. Generally after active treatment, the prognosis is better. Whether it is cancer or warts, both need to be actively treated after discovery; early detection and early treatment can significantly improve the prognosis.
