Uterine fibroids and menstrual blood clots issues?


Hello Doctor, I am 29 years old.
I visited the obstetrics and gynecology department at Mackay Memorial Hospital in Hsinchu for menstrual issues in March of last year and the year before.
I underwent a transvaginal ultrasound, which suggested symptoms of polycystic ovary syndrome; however, the doctor believed it had little impact on my menstrual cycle (occasional).
Therefore, no specific treatment was initiated, and I only took medication to induce menstruation when I experienced occasional delays or missed periods.
Recently, I did not have my period in April (the last one was on March 25), so I went to a clinic for an examination.
The clinic doctor asked if I wanted to undergo a transvaginal ultrasound and Pap smear, which I agreed to.
During the transvaginal ultrasound, the doctor informed me that a 2 cm uterine fibroid was found.
Since it does not affect my daily life and there are no other unusual symptoms, the doctor advised me not to worry about it and did not specify its location.

My main questions are: since this condition was not present during my visit to Mackay last March, is a growth of about 2 cm in a little over a year considered rapid? (I am somewhat concerned about the possibility of malignant uterine fibroids.) Additionally, if I follow up every 3-6 months and the growth rate reaches a certain size, at what point would surgery be recommended? Since I just got married and have plans for children, if surgery reveals malignancy, would that mean I would lose the ability to conceive? Furthermore, my menstrual periods last about 7 days, and around the 4th day, I notice a round blood clot approximately 2x2 cm in size.
Could this be related to the uterine fibroid? Thank you for your response, and I appreciate your time in addressing my concerns.

1.
Fibroids are 99.9% benign, and a size of 2 centimeters is unlikely to have any malignant potential.
It is recommended to simply observe for 3 to 6 months without the need for surgery, and instead, it is advisable to consider early childbearing.
2.
Yes, the presence of blood clots can sometimes be a common phenomenon associated with fibroids.

Understanding uterine fibroids and menstrual blood clots is essential for women, especially when considering reproductive health and future family planning. Uterine fibroids, also known as leiomyomas, are non-cancerous growths of the uterus that often appear during childbearing years. They can vary in size, number, and location, and while many women with fibroids experience no symptoms, others may face significant issues, including heavy menstrual bleeding, pelvic pain, and complications during pregnancy.

In your case, you mentioned that a 2 cm fibroid was discovered during a recent ultrasound, and your doctor advised that it does not require immediate treatment since it is not affecting your daily life. This is a common approach, as many fibroids remain stable in size and do not necessitate intervention. However, your concern about the growth rate of the fibroid and the potential for malignancy is valid.

To address your first question, a 2 cm increase in fibroid size over a year is generally not considered rapid growth. Fibroids can grow at different rates, and many remain the same size for years. The risk of a fibroid being malignant is low, especially in younger women like yourself. However, if there are changes in your symptoms or if the fibroid grows significantly, further evaluation may be warranted.

Regarding monitoring, it is typically recommended to have follow-up ultrasounds every 3 to 6 months to assess the fibroid's growth. If the fibroid grows to 5 cm or larger, or if you experience worsening symptoms such as increased bleeding or pain, your healthcare provider may discuss treatment options, which could include medication or surgical intervention. Surgical options may involve myomectomy (removal of the fibroid) or hysterectomy (removal of the uterus), depending on your future fertility plans and the fibroid's characteristics.

As for your concern about the potential for malignancy, it is essential to understand that the vast majority of fibroids are benign. However, if a fibroid is suspected to be growing rapidly or if there are atypical features on imaging, your doctor may recommend a biopsy or further imaging studies to rule out cancer. In the rare event that a fibroid is found to be malignant, treatment options would be discussed based on the specific diagnosis and your reproductive goals.

Regarding the blood clots you experience during your menstrual cycle, it is not uncommon for women with fibroids to notice larger clots, especially if they have heavy menstrual bleeding. The presence of a 2x2 cm blood clot could be related to the fibroid, as fibroids can contribute to heavier menstrual flow and the formation of clots. However, it is essential to monitor the size and frequency of these clots. If you notice an increase in size or frequency, or if you experience significant pain or other concerning symptoms, it would be prudent to consult your healthcare provider.

In summary, while your current fibroid does not appear to be a cause for immediate concern, regular monitoring and open communication with your healthcare provider are crucial. If you have plans for pregnancy, discussing these with your doctor can help ensure that any necessary interventions are timed appropriately. Remember, maintaining a healthy lifestyle, managing stress, and regular check-ups can also contribute positively to your reproductive health. If you have any further questions or concerns, do not hesitate to reach out to your healthcare provider for personalized advice and support.
