Found a 2cm cyst. bleeding in between period. extremely loud stomach growling and very bloated for 30 days. i wake up with growling. ovarian cancer?

No connection: Ovarian cysts do not cause gastrointestinal symptoms such as borborygmi (increased intestinal sounds). Your gynecologist can better answer questions regarding the risk of ovarian cancer with ovarian cysts.

It's possible: I assume you mean you have an ovarian cyst. If this was seen on ultrasound, it's likely to be a cyst and not cancer. You are very young, and there are many things that can cause the symptoms you describe. However, bloating is a common symptom among women who are later diagnosed with ovarian cancer. I'd go back to your doctor and emphasize how bloated you've been, and ask the same question!
