What is the best method to address a calcified fibroid tumor that is causing frequent urination and bowel movement issues?

Not sure the: 'calcified tumor' and your symptoms match up. Fibroids of the uterus commonly calcify, but these can cause bleeding issues or painful intercourse. There are radiofrequency ablation or cryotherapy for these, but your symptoms are odd enough to warrant a frank discussion with one or more gynecologist.

Hysterectomy: I'm going to assume this is a common calcified leiomyoma / fibroid of the uterus and that it's falling forward onto the bladder causing urinary urgency and pushing backward onto the bowel and causing constipation. These calcified tumors are unlikely to regress at menopause and elective hysterectomy might be a reasonable option if your physician is good with it.
