Introduction
Breast cancer is a major problem for women in the 21st century, being the most commonly diagnosed cancer among women worldwide. It greatly affects their physical and mental health, and unfortunately, many lives are lost due to this disease. Breast cancer is more challenging to treat in its later stages, so early detection is essential for successful treatment. Therefore, early diagnosis and prevention are vital for reducing the number of deaths. The use of artificial intelligence (AI) in screening methods is a promising new approach that shows potential in detecting breast cancer early, leading to better outcomes for patients.
What Is a Mammogram?
A mammogram is comparable to a breast x-ray. There are two main uses for mammograms. The first is to look for signs of breast cancer in women who do not have any clinical symptoms, which is called a screening mammogram. During this procedure, typically two or more x-ray images are taken of each breast. These images can help spot tumors that are too small to be felt, and they can also detect tiny deposits of calcium called microcalcifications, which sometimes represent the existence of breast cancer.
The second purpose of mammograms is to check for breast cancer in women who have noticed a lump or some other symptom related to the disease. This is known as a diagnostic mammogram. Symptoms of breast cancer may include a lump, skin texture changes, discharge from the nipples, breast pain, or alterations in breast size or shape. However, it is crucial to understand that these indicators can also arise due to non-cancerous circumstances. A diagnostic mammogram can help doctors investigate changes found during a screening mammogram or examine breast tissue when obtaining a regular screening mammogram is challenging, like when a patient has breast implants.
What Is the Role of Artificial Intelligence in the Early Detection of Breast Cancer From Mammograms?
Breast cancer is a major cause of death among women globally. It is a complex disease influenced by factors like gender, genetics, environment, and job. The best way to fight it is through early screening. Screening has greatly lowered death rates. Using AI in screening, like looking at biopsy slides, improves the chances of successful treatment. This field has become more popular recently and has a bright future.

Computational Radiology in Breast Cancer Screening
Computational radiology, which involves computer vision and pattern recognition, now handles tasks that used to be done by experts. It helps classify lesions using BIRADS (breast imaging-reporting and data system) and provides systematic reports. It also extracts information from images to predict how well therapies will work. Machine learning and deep learning are vital parts of AI in breast cancer imaging. Machine learning stores a lot of data and uses it to make predictions. Deep learning is an improved method of machine learning that makes use of artificial neural networks to recognize and classify images. AI in breast cancer screening focuses on finding and classifying tumors as benign or malignant.

Mammography in Breast Cancer Screening
In the world of breast cancer treatment, AI is used to help find signs of cancer early using data from radiology and biopsy slides. People worldwide are working on creating smart algorithms to understand mammograms better and reduce the number of incorrect results. AI is improving the chances of spotting breast cancer that has spread to lymph nodes. These AI systems work differently depending on a person's risk factors and individual characteristics.
Mammograms, which are detailed breast X-rays, are the most common way to screen for breast cancer. AI is used to analyze these images, find things like breast lumps and segment masses, assess breast density, and estimate cancer risk. Lumps are significant in breast cancer detection, making them a key part of computer-assisted diagnosis. AI can also spot tiny calcium deposits called microcalcifications. Correctly segmenting breast masses using AI is vital for accurate diagnosis. AI helps assess breast density based on 2D mammograms, and it estimates cancer risk by considering factors like age, family history, and lifestyle.

Computer-Assisted Diagnosis (Cad) In Breast Cancer Detection
About twenty years ago, computer-assisted diagnosis (CAD) became a part of breast cancer screening. The research compared the effectiveness of radiologists reading mammograms on their own versus using CAD. It didn't show a clear advantage of one over the other, but combining both approaches seemed to work better. AI-based CAD has the potential to achieve high sensitivity, making it useful for speeding up the reading of breast tomosynthesis images. CAD is often used as a second opinion in patient care, but it needs careful testing to prove its effectiveness over time.

Immunotherapy and AI
Immunotherapy is a way to use a patient's immune system to fight cancer. AI algorithms can help find specific markers on cancer cells, but more research is needed in this area. AI can also predict how well a patient will respond to immunotherapy. Studies suggest that certain patterns seen in medical images can help predict how well immunotherapy will work for different types of cancer in various parts of the body.
What Are the Advantages of AI in Screening for Breast Cancer?
-
AI improves the accuracy and consistency of mammogram interpretation. AI processes mammographic data with speed and precision, reducing human error.
-
It excels at spotting subtle, early-stage signs of breast cancer.
-
AI processes mammograms faster than humans, aiding healthcare systems with high patient volumes.
-
Faster results reduce patient anxiety and enable early interventions.
-
Early detection improves treatment effectiveness and patient survival.
-
AI helps in identifying small, subtle abnormalities that are challenging for humans to spot. It can detect microcalcifications and minor masses that may indicate malignancy. Early detection improves the manageability of breast cancer.
-
AI can help reduce false-positive mammogram results. This reduces patient stress, additional tests, and unnecessary medical procedures.
-
AI goes beyond mammogram interpretation to offer personalized risk assessment. It considers a patient's medical history and genetic factors.
-
AI identifies individuals at higher risk for breast cancer, ensuring they receive appropriate screenings and preventive measures. This personalized approach enhances the effectiveness of breast cancer screening and prevention.
Conclusion
The use of artificial intelligence in finding breast cancer early from mammograms is a real game-changer. AI systems make mammogram readings more accurate, consistent, and faster, helping catch cancer sooner and benefiting patients. They are great at spotting tiny issues and lowering the chance of false alarms. They can also personalize the risk assessment, making breast cancer checks more efficient and patient-focused. As AI keeps getting better, it has the potential to play a big role in fighting breast cancer, saving lives, and making healthcare better for all.
