Is there any evidence linking ovarian cancer to hrt?

Yes, ERT does. Unopposed estrogen therapy (ert) does increase the risk of ovarian cancer. The jury is still out on HRT although the women health institute study did find that continuous combined HRT may increase the risk of ovarian cancer slightly. Keep in mind that ovarian cancer is rare, much rarer than breast cancer. See your doc for a frank talk on this.
Link from ACS. Here is a good review from the american cancer society. http://www.cancer.org/cancer/cancercauses/othercarcinogens/medicaltreatments/menopausal-hormone-replacement-therapy-and-cancer-risk.
NO. The risk of uterine cancer makes unopposed estrogen a risk, if you have a uterus, and take estrogen, you must also take a progestin. If you have your ovaries, and not a uterus, you can take estrogen by itself.

At 27, I had ovarian cancer and then a hysterectomy. Is HRT safe for me? My cancer was malignant dysgermanoma.

Should be. Based on your cancer history, HRT should be safe but there can be other contraindications so you should discuss it with your doctor. Read more...
Yes. Before your ovaries were removed, they made hormones (hrt) so you should be fine using replacement after the surgery. That particular type of cancer should not be affected by replacement. A person with breast cancer, active blood clots, certain types of uterine cancer or undiagnosed vaginal bleeding should not use hrt. Read more...

On hormone replacement therapy since hysterectomy at age 31 for ovarian cancer- now 50. Do I need to end HRT for normal menopause age?

Add progesterone. Estrogen continues to be made from the fat cells and adrenal glands so you need to be on natural Progesterone forever to balance the estrogen. It stimulates the p53 gene to protect you from cancers. Read more...

Is there a link between ovarian cancer and hormone replacement therapy?

No. Causes of ovarian cancer are poorly understood. In some cases, there is a hereditary risk. There is no evidence that hormone therapy affects ovarian cancer. There is evidence that use of birth control pills is protective against ovarian cancer. Read more...
Possibly slight. The risk of ovarian cancer is quite low. Some studies have shown a possible small increased risk. In most instances the risk is not considered great enough to eliminate hormone replacement therapy as a viable option for women who are in need. Read more...

How much does hormone replacement therapy play in the development of ovarian cancer?

Probably none. There does not appear to be a correlation with hormone replacement therapy and ovarian cancer. Nevertheless, i always balance estrogen treatment with progesterone. There is some evidence that women estrogen dominance (overweight, infertile, polycystic ovaries and women who don't ovulate) have higher estrogen dependent cancers like breast, colon, uterine and ovarian. It's all about balance. Read more...

Is there any evidence that links pregnancy-related hormone therapy treatments with increased risk of ovarian cancer?

Tough question. By this i assume you mean for in vitro vertilization. Any hormone manipulation has a potential for side effects. Increased Estrogens increases the risk of breast and cervical cancer, but lower estrogen increases risks of ovary and uterus--also influenced by Progesterone and other hormones. This is not a straight forward topic, as there are many studies that contradict each other. Read more...
