Abnormal Menstrual Cycles and Cervical Screening for Women Over 40

Irregular menstrual periods and cervical cytology?

Hello Dr.
Lin,
I have a few questions I would like to ask you:
1.
If I am over 40 years old, unmarried, and have no sexual experience, do I still need to have a Pap smear?
2.
I have been experiencing irregular menstrual cycles over the past year.
Initially, my periods were occurring every two months, but later, I had some months where my period lasted over ten days.
Recently, for the past four months, I have been having two periods each month; for example, one at the beginning of the month and another in the middle or late month, with about 7-10 days in between.
The first day of my period is not very noticeable, but it becomes more pronounced from the second to the fourth day, with a normal amount of flow—not excessive.
After that, the flow is very light.
I am concerned whether this could be related to menopause or another issue.

3.
I previously had a scan, and the doctor mentioned that my endometrium was a bit thick, but further examination was needed to determine the cause.
They also noted that I am unmarried.
I had two courses of medication for three days each, but I did not return for follow-up.
If there is an issue with the endometrium, what symptoms might I experience?
Thank you for your response.

1.
Cervical cancer is associated with human papillomavirus (HPV).
If infected with high-risk types of the virus, it is important to be cautious about the possibility of cervical lesions.
If one is unwilling to undergo a Pap smear, a small cotton swab can be used to collect vaginal secretions to check for viral infection.

2.
It is evident that ovarian function is relatively unstable.
It is recommended to visit a clinic for hormone testing.
3.
The endometrium is thickened, and a biopsy is necessary to determine the cause.
If there is no sexual experience, the physician will take a more conservative approach, initially using progesterone to induce menstruation to see if it can lead to natural shedding of the endometrium.
If that is not effective, it is advised to perform a biopsy under anesthesia using a thin tube to obtain a sample of the endometrium, as this is the most accurate method.

When it comes to cervical screening and understanding abnormal menstrual cycles, especially for women over 40, there are several important considerations to keep in mind.
1. Cervical Screening for Women Over 40: Regardless of sexual experience, it is generally recommended that women begin cervical cancer screening at age 21 and continue until age 65. For women aged 30 to 65, a Pap smear combined with HPV testing every five years is often advised. Even if you are unmarried and have no sexual experience, it is still prudent to undergo cervical screening. The rationale behind this is that HPV, the primary cause of cervical cancer, can be transmitted through non-penetrative sexual contact, and some strains of HPV can remain dormant for years before causing abnormalities.

2. Understanding Abnormal Menstrual Cycles: The changes in your menstrual cycle, such as having periods that are irregular, prolonged, or occurring more frequently, can be concerning. These symptoms may indicate a variety of conditions, including hormonal imbalances, uterine fibroids, or even the onset of perimenopause, which is the transitional phase leading up to menopause. Perimenopause can start in a woman's 40s and is characterized by irregular menstrual cycles, hot flashes, night sweats, and other symptoms. It is essential to consult with a healthcare provider to evaluate these changes, as they can perform necessary tests, including blood tests to check hormone levels and imaging studies to assess the uterine lining.

3. Symptoms of Uterine Issues: If there are concerns about the thickness of the endometrial lining, this can sometimes lead to abnormal bleeding patterns. Symptoms of potential issues with the endometrium may include heavy or prolonged menstrual bleeding, bleeding between periods, or postmenopausal bleeding. Thickened endometrial tissue can be a sign of conditions such as endometrial hyperplasia, which can increase the risk of endometrial cancer if left untreated. Therefore, it is crucial to follow up with your healthcare provider for further evaluation, which may include a biopsy to assess the endometrial tissue.

In summary, it is advisable for women over 40 to engage in regular cervical screening, regardless of sexual history, to catch any potential issues early. Additionally, any significant changes in menstrual cycles warrant a thorough evaluation by a healthcare professional to rule out underlying conditions. If there are concerns about the endometrial lining, further investigation is necessary to ensure that any potential problems are addressed promptly. Always prioritize open communication with your healthcare provider to ensure that your health needs are met effectively.
