Why Breasts Ultrasound is the Preferred Choice for Women Under 35?

-

Breast cancer screening is an essential part of women's healthcare, but the imaging method used varies depending on age and breast tissue composition. Women under 35 are often advised to undergo ultrasound instead of mammography for breast evaluations. Why is that? Let’s break it down.

Understanding Breast Tissue & Imaging Approaches

Breast tissue composition changes with age, hormones, and physiological conditions such as pregnancy and lactation. This affects how imaging techniques like ultrasound and mammography detect abnormalities.

Breast Tissue Types & Best Imaging Modality

1️⃣ Mostly Glandular (Young Women, <35 years)

✅ Best assessed with ultrasound because glandular tissue is dense, making mammography less effective. Dense breast tissue can obscure abnormalities in mammograms, making it harder to detect issues like tumors.

2️⃣ Mixed Glandular & Fatty (Transition Phase, 35+ years)

✅ Requires both mammography & ultrasound for better detection. As women age, breast tissue gradually transitions from glandular to fatty, which improves mammographic accuracy.

3️⃣ Mostly Fatty (Older Women, Postmenopausal)

✅ Mammography is the preferred method because fatty tissue provides better contrast, making it easier to spot malignancies.

Key Takeaways

💡 Why Ultrasound is the First Choice for Women Under 35

👉 Before 35, breast tissue is denser and more glandular, which makes it difficult for mammograms to detect abnormalities clearly. Ultrasound is preferred as it provides a clearer image of dense breast tissue.

📌 Mammography is still recommended for high-risk women under 35, but for most young women, ultrasound is the primary screening tool.

👉 After 35, mammography becomes the preferred choice because fatty replacement of breast tissue improves contrast, making cancerous changes more visible.

Final Thoughts

Breast cancer detection is highly dependent on age and tissue composition. Women under 35 benefit more from ultrasound, while those over 35 rely more on mammography. However, in certain cases, a combination of both is necessary to ensure accuracy. Always consult with a healthcare provider to determine the best screening approach for you.

Stay proactive about your breast health! Early detection saves lives.

Hepatic Pregnancy: A Rare Form of Ectopic Pregnancy

-
Image
A few days ago, a colleague shared a video of a real-time pregnancy developing in the liver, and I was in complete disbelief. This is an extremely rare form of ectopic pregnancy, with an estimated incidence of 1 in 8,000 births. While abdominal pregnancies are already uncommon, hepatic pregnancies—where the embryo implants in the liver—are even more exceptional. Recent Case in Namibia A recently reported case in Namibia has reignited discussions in the medical community about this rare phenomenon. The video evidence highlights the complexity of hepatic pregnancies and the significant challenges in their management. Understanding Hepatic Pregnancy Hepatic pregnancy falls under the broader category of abdominal pregnancies, which account for approximately 1.4% of all ectopic pregnancies. Most abdominal pregnancies implant in the pelvis, but in extremely rare cases, implantation occurs in the upper abdomen, particularly in the liver. Case Study from the Literature A documented case publi...

Choris prosopos fetalis: Faceless birth defect

-
Image
"Choris prosopos fetalis" or absent fetal face is a congenital birth defect that can be classified in the arthrogryposis multiplex congentia . This is the absence of facial bone due to failure of ossification centres, and eventual bone formation. The inability for bone formation results in the malformation of other facial organs like the mouth, nose and eyes. Choris prosopos fetalis is a very rare form of facial deformity with almost zero survival rate this is very similar to but not  Frontonasal Dysplasia , also known as Median Cleft Face Syndrome, is a condition in which the nose has a flat, wide appearance, and the eyes may be wide-set. There is a groove of varying degrees, which runs down the middle of the face across the nose. In some cases the tip of the nose is missing. A gap with extra folds of skin covering it may appear on the front of the head. Craniofacial defects are caused by the abnormal growth or development of the head and/or facial bones wh...

Medical news: live shots of an ovulating ovary

Alot is known on the physiology of female reproductive system . These knowledge has been the fulcrum on which modern day reproductive medicine is practiced, the success of medical practice is hinged on the culmination of all piece of know. But not all that has been taught will ever be seen, some processes occurs when man isn't looking. In a very rare sight during surgery, the first time for many practitioners, there was an ovulation caught on camera. The pic below is a live still image of an ongoing ovulation during surgery. Exciting sight for many In the collage picture the process starts from top right and ends in bottom right of the image.
