I was diagnosed with 2 precancer, sesille, serrated polyps 3 mm and 6 mm in appendeceal orifice, plus a mass in cecum Concerning of Malignancy. After 3 colonoscopies, 3 Catscsns, and 3 surgeons, I now have a fine Dr. That plans surgery for removal of appendix and polyp in appendeceal orifice, if cancer cells are found, the s complete resection will be done. I understand this is very rare, only record of 1500 in USA (or total)? Has anyone experienced cancer of appendix by polyps?thank you!!
