<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I am 47 years old. 6 months ago I experienced an extra long mentstural cycle 45 days and since then have had 3 normal cycles 30 Daysthen a short cycle 16 Days. This pattern has now repeated itself twice I have a slightly bulky uterus - 9cm. Ultrasound report states that the myometrium is hetergeneous and I have a small fibroid. Gyne exam states normal looking cervix and no obvious masses in the uterus which is mobile. Does it sound like I have cancer?  <response>: Hi and welcome to Chat Doctor. Thank you for your query. No, this isnt cancer, this is fibroid and fibroid is benign tumor. It is hard to say does this cause your symptoms, but you should find the cause of your period abnormality. It can be hormonal imbalance or ovarian pathology. Fibroid can cause bleeding and pain if become enlarged enough. You are in premenopausal age, and it can be expected to have such difficulties. You just need to do frequent check up and consider hormonal therapy. Wish you good health.
