Contact usBeginning around age 21, women should visit their doctor for regular Pap tests. Unless you have an elevated risk of cervical cancer, it’s usually recommended that women between the ages of 21-65 have a Pap test every three years. Treatment options for cervical cancer depend on many factors, including how advanced the cancer is when detected, your age, other health issues you may have, the size of the tumor and whether you wish to have children in the future. At Hoag, we offer the latest treatment options for cervical cancer.
Research to develop a definitive, non-invasive screening test for ovarian cancer is ongoing. Currently, the main tests used to diagnose ovarian cancer are: CA-125 Blood Test, Transvaginal ultrasound, and Surgical biopsy. After diagnosis, your fellowship-trained Hoag gynecologic oncologist will work with you to determine a personalized treatment plan.
Currently, there is no definitive, non-invasive test to screen for uterine cancer. If you have symptoms that suggest uterine cancer, your doctor will talk to you about the issues you are having, followed by a pelvic exam. Other tests or procedures to help diagnose or rule out uterine cancer may include: Transvaginal ultrasound and Endometrial biopsy. Your treatment options for uterine cancer can depend on several factors, including your age, other conditions you may have and how advanced the cancer is at the time of diagnosis. Hoag can help with several treatment options for uterine cancer.
If you have symptoms that might suggest vaginal cancer, your doctor will talk to you about the issues you’re experiencing, followed by a pelvic exam or Pap test to check for infection with HPV, which can cause vaginal cancer. If those tests suggest further investigation, the doctor may refer you for additional tests, including: colposcopy, biopsy, and imaging tests. Treatment options for vaginal cancer depend on many factors, including how advanced the cancer is when detected, your age, other health issues you may have, the size and location of the tumors and whether you wish to have children in the future.
If you have symptoms that might suggest vulvar cancer, your doctor will talk to you about the issues you’re experiencing, followed by a pelvic exam or Pap test to check for infection with HPV, which can cause vulvar cancer. If those tests suggest further investigation, the doctor may refer you for additional tests, including: colposcopy, biopsy, and imaging tests. Treatment options for vulvar cancer depend on many factors, including how advanced the cancer is when detected, your age, other health issues you may have, the size and location of the tumors and whether you wish to have children in the future.
