Breast cancer screening is important because it can help detect cancer before any signs or symptoms appear. Identifying breast cancer early may allow treatment to begin sooner and may improve treatment outcomes.
However, many women are still unsure about when to begin breast check-ups, whether they need a mammogram and how often screening should be repeated. The right screening plan depends on a woman’s age, medical history, family history and personal risk factors.
What Is Breast Cancer Screening?
Breast cancer screening is the process of checking a woman’s breasts for cancer when she does not have any symptoms. Screening does not prevent breast cancer, but it can help detect abnormalities at an earlier and potentially more treatable stage.
The main methods of breast cancer screening include:
Breast self-awareness
Clinical breast examination
Mammography
Breast ultrasound
Breast MRI for selected high-risk women
A screening mammogram is performed when a woman does not have symptoms. A diagnostic mammogram or another imaging test may be recommended if she has a breast lump, nipple discharge, persistent breast pain or another concerning change.
When Should Women Start Regular Breast Check-Ups?
From early adulthood, women should become familiar with the normal appearance and feel of their breasts. This does not mean following a complicated examination routine. It simply means being aware of any changes and reporting unusual findings to a healthcare professional.
In India, population-based screening programmes include clinical breast examination for women aged 30 and above. During this examination, a trained healthcare professional checks the breasts and underarm areas for lumps or other abnormalities.
Women should also discuss their personal breast cancer risk during routine health check-ups. An experienced urogynecologist in Kerala can support women’s preventive healthcare by reviewing their medical, menstrual, reproductive and family history and referring them to the appropriate specialist or screening service when necessary.
When Should Women Begin Mammograms?
There is no single mammogram schedule that is suitable for every woman. Recommendations may vary between countries and medical organisations.
Many guidelines recommend that women at average risk discuss mammography with their healthcare provider beginning at age 40. The United States Preventive Services Task Force recommends mammography every two years for women between the ages of 40 and 74. The World Health Organization generally discusses organised mammography screening for women aged 50 to 69 in healthcare systems where screening, diagnosis and treatment are readily available.
Women should therefore not use age alone to decide when to begin screening. A healthcare professional can recommend an appropriate starting age and screening frequency based on personal risk factors, medical history and locally followed guidelines.
Who May Need Earlier Screening?
Some women have a higher-than-average risk of developing breast cancer and may need to begin screening earlier or undergo screening more frequently.
Risk may be higher among women who have:
A mother, sister or daughter diagnosed with breast cancer
A strong family history of breast or ovarian cancer
A known BRCA1, BRCA2 or another cancer-related genetic mutation
A history of radiation treatment to the chest at a young age
A personal history of breast cancer
Certain high-risk breast conditions
Dense breast tissue
A risk assessment showing a high lifetime risk of breast cancer
Women at high risk may be advised to undergo both mammography and breast MRI every year, often beginning earlier than routine screening. Some high-risk women may need to start annual mammograms and breast MRI around the age of 30.
The exact starting age and screening schedule should always be decided with a qualified healthcare professional.
What Is a Mammogram?
A mammogram is a low-dose X-ray examination of the breasts. During the test, each breast is placed between two plates and compressed briefly to obtain clear images.
The pressure may feel uncomfortable, but it usually lasts only a few seconds. The complete procedure generally takes around 20 minutes.
Women should inform the imaging centre if they:
Are pregnant or may be pregnant
Are breastfeeding
Have breast implants
Have previously undergone breast surgery
Have noticed a lump or another change in the breast
Previous mammogram reports should also be carried whenever possible. Comparing earlier and current images can help the radiologist identify any changes.
Is Breast Ultrasound a Replacement for Mammography?
Breast ultrasound can provide additional information about a lump or an abnormal area detected during a clinical examination or mammogram. It can be particularly helpful in distinguishing between fluid-filled cysts and solid masses.
However, ultrasound is not generally considered a complete replacement for mammography in routine breast cancer screening. A doctor may recommend ultrasound in addition to mammography, especially for women with dense breast tissue or specific breast symptoms.
What Are the Advantages and Limitations of Screening?
The main benefit of breast cancer screening is the possibility of detecting cancer before it produces symptoms or reaches a more advanced stage.
However, screening also has certain limitations. Mammograms may sometimes:
Miss an existing cancer
Detect an abnormality that is not cancer
Lead to additional imaging or biopsy
Identify a slow-growing cancer that may never have caused harm
Cause temporary discomfort or anxiety
These limitations do not mean that women should avoid screening. Instead, they highlight the importance of discussing the potential benefits and limitations with a healthcare professional before making an informed decision.
Breast Changes You Should Never Ignore
Routine breast cancer screening is intended for women who do not have any symptoms. If you notice a change in your breast, do not wait until your next scheduled mammogram.
Consult a doctor promptly if you experience:
A new lump in the breast or underarm
Thickening or swelling in any part of the breast
A noticeable change in breast size or shape
Dimpling, redness or irritation of the breast skin
Nipple discharge, particularly if it is bloody
A nipple that has recently turned inward
Persistent pain in one area of the breast
Changes in the skin around the nipple
