Mammogram Interval: Master the c...
The importance of breast cancer prevention and treatment
Breast cancer is one of the most common cancers in women worldwide, and early detection and treatment are key to improving survival. According to the Hong Kong Cancer Registry, breast cancer accounts for 27.4% of new cancer cases in women in Hong Kong, indicating that its importance cannot be ignored. Mammography () is currently the most effective screening tool and can detect abnormalities before tumors are palpable. However, many women question the "" that directly affects the effectiveness of screening. This article will shed light on these myths and help women master the correct exam intervals to protect breast health.
Standard Quality Inspection Interval Recommendations
In general, women over 40 years of age are recommended to have mammography every 1-2 years. Guidelines vary slightly by country or region.
- Hong Kong Health Bureau: Women over 40 years old are recommended to take it every two years
- American Cancer Society: It is recommended that women aged 45 to 54 change once a year, and women over 55 years old change once every two years
- EU guidelines: recommended every 2-3 years for women aged 50-69
Studies show that regular treatment can reduce breast cancer mortality by 20-30%. It is worth noting that the "price of mammography" is about HK$300-500 in public hospitals in Hong Kong and HK$1,000-HK$2,000 in private hospitals, and the price difference may affect the willingness of some women to undergo examinations.
Factors affecting the examination interval
Age is one of the most important factors.
| age group | Recommended intervals | risk |
|---|---|---|
| Under 40 years old | Routine inspections are not recommended | Low risk |
| 40-49 years old | Once every 1-2 years | Medium risk |
| 50 years of age or older | Once a year or once every two years | High Risk |
Other influencing factors include family history (close relatives with a history of breast cancer have a 2-3 fold increased risk), personal breast history (such as benign tumors), and breast density (dense breast tissue can affect the accuracy of the test). These factors may require adjustments to standard recommendations.
How to assess personal risk?
In addition to standard recommendations, women should use risk assessment tools to understand their condition. Commonly used assessment tools in Hong Kong include the Gale and Tyler Kuzik models, which calculate risk values by considering factors such as age, menstrual history, fertility history, and family history. It is also important to have a monthly self-check, and it is best to do it one week after your period ends. If any abnormalities are found, you should immediately consult a doctor to discuss whether you need to move forward. It is worth noting that despite the high "mammography price", regular health check-ups are still a necessary health investment for high-risk groups.
Reduces unnecessary X-ray exposure
Mammography is safe, but still requires a small amount of radiation exposure. Modern digital mammography (FFDM) reduces radiation by 20-30% and provides clearer images than traditional film-based radiation. Doctors weigh the benefits of testing (early detection of cancer) and risk (radiation exposure), and for women at low risk, too frequent "" may not be necessary. In general, women under 40 are advised not to need routine examinations unless they have special risk factors to avoid unnecessary radiation.
frequently asked questions
Q: Does the menstrual cycle affect test results?
Yes, it is recommended to book an examination one week after menstruation to improve comfort and accuracy, as the breasts become more sensitive and swelling may occur one week before menstruation.
Q: Can mammography with implants be done?
Yes, but you need to inform the technician in advance, and they will adjust the inspection method for you. The implant can obscure some of the breast tissue and may require additional ultrasound.
Q: Does it hurt during testing?
This test requires flattening the breast tissue, which can cause temporary discomfort, but it usually doesn't last long. If you are particularly sensitive, consider avoiding caffeine or taking a light pain reliever before the test.
Regular health checkups are key
Regardless of the "mammography price", regular check-ups are one of the most effective ways to prevent breast cancer. Understand your risk factors, discuss appropriate intervals with your doctor, and stick to your checkup plan. Hong Kong's healthcare system offers a variety of options, from public hospitals to private clinics, allowing women to choose the best method for their situation. Remember, the cure rate of breast cancer detected early can reach over 90%, and regular check-ups are the best investment in your health.乳房造影檢查
