1. Basic Understanding of Breast Screening

Breast screening is an integral part of women's healthcare, especially for the early detection of breast cancer. According to the Hong Kong Cancer Registry, breast cancer is the most common cancer among women in Hong Kong, with more than 4,000 new cases each year. Early detection not only increases cure rates but also reduces the complexity and cost of treatment.

Common breast screening methods include mammography, breast ultrasound, and mammography. Each method has its advantages and disadvantages, making it suitable for different situations. Mammography is a traditional screening method suitable for women over 50 years of age. Breast ultrasound is suitable for young women and dense breasts. It is attracting more and more attention due to its high accuracy. Breast magnetic resonance imaging is mainly used for further examination in high-risk groups.

When choosing a screening method, factors such as the individual's age, breast density, and family history should be considered. For example, women with dense breasts are more suitable, as they can show the tissue structure more clearly and reduce the risk of missing a diagnosis.

1.1 Importance of Breast Screening

The early symptoms of breast cancer are often not obvious, and by the time obvious symptoms appear, they may have progressed from the middle stage. Therefore, regular breast screenings are key to early detection of breast cancer. The Hong Kong Health Bureau recommends that women over 40 years of age have more frequent breast screenings once a year in the high-risk group.3d乳房造影檢查

1.2 Common Breast Screening Methods

• Mammogram: A traditional screening method suitable for women over 50 years of age.
• Breast ultrasound: It does not contain radiation and is suitable for young women and women with dense breasts.
• A: High precision for high-density breast.
• Magnetic resonance imaging of the breast: It is mainly used for further examination in the high-risk group.

2.3D mammography

(also known as tomography mammography) is an advanced technique developed in recent years that takes breast images from multiple angles and reconstructs stereoscopic images through a computer. This technique provides a clearer picture of the structure of breast tissue, making it particularly suitable for women with dense breasts.

2.1 Advantages: High precision, suitable for dense breasts

The biggest advantage is the high accuracy. Studies show that 3D technology can improve breast cancer detection rates by about 40%, especially for women with dense breasts. Additionally, 3D technology reduces false positive results and avoids unnecessary biopsies.

2.2 Cons: High Radiation Dose and Cost

But there are also some disadvantages. First, the radiation dose is slightly higher than that of conventional radiographs, but it is still within a safe range. Second, mammography is expensive, costing about HK$2,000 to HK$4,000 for a single test, which is currently not covered by the free screening scheme provided by the Hong Kong government.

3. Pros and Cons of Breast Ultrasound

Breast ultrasound is also a common screening method, especially for young women and women with dense breasts. Its biggest advantage is that it is radiation-free and relatively low cost.

3.1 Advantages: No Radiation, Low Cost

Breast ultrasound does not use radiation, so it is suitable for pregnant women and young women. Moreover, its cost is around HK$800 to HK$1,500, which is much lower than 3D mammography. Breast ultrasound programs are also included in some screening programs funded by the Hong Kong government.

3.2 Cons: Operator Influence, Insufficient Penetration into High-Density Breasts

The accuracy of breast ultrasound largely depends on the operator's skill level, and results may vary from hospital to hospital. In addition, for dense breasts, ultrasound has low penetration and may miss the diagnosis of small tumors.

4. 3D Mammography and Breast Ultrasound: A Comparative Analysis

When choosing a screening method, various factors should be considered, including age, breast density, and risk factors.

4.1 Applies to: Age, Breast Density, and Risk Factors

Young women (under 40 years old) or women with dense breasts are suitable for breast ultrasound. On the other hand, people over 50 or at high risk may consider 3D mammography.乳房造影政府

4.2 Purpose of the examination: screening, diagnosis, and follow-up

An ultrasound or x-ray of the breast may be sufficient for routine screening. However, 3D mammography is more accurate for diagnosing or tracking known lesions.

5. How to make the best choice?

Choosing the best breast screening method requires comprehensive consideration of individual circumstances and sufficient communication with professional doctors.

5.1 Consult a doctor: Create a screening plan based on your individual circumstances

Women are advised to discuss personal risk factors (family history, breast density, etc.) with their doctor and develop an individual screening plan before choosing a screening method. Some hospitals in Hong Kong offer a combination package of different screening methods, which you can choose according to your needs.

5.2 Overarching Considerations: Risks, Costs, and Comfort

In addition to accuracy, factors such as cost and comfort should also be considered. For example, 3D mammography is more expensive but provides more accurate results. Breast ultrasounds are inexpensive, but they may require more than one test. In addition, the funding system provided by the Hong Kong government may also affect your choice, so it is recommended to understand the relevant policies in advance.
