Breast Class 3 nodules are fast-growing and painful with a low probability of being cancerous, but are generally benign and patients should be followed up for regular checkups.
The BI-RADS (Breast Imaging Reporting and Data System) classification is a risk assessment of the benign and malignant nature of breast nodules based on the results of breast ultrasound, mammogram, etc. Grade 3 nodules have a high likelihood of being benign, and the probability of being malignant is less than 2%.
Class 3 breast nodules that grow faster and are painful are more likely to be cystic hyperplasia of the breast, i.e., breast hyperplasia, which is characterized by breast lumps and pain before and during menstruation. It may also be a benign condition such as an inflammatory nodule.
Grade 3 breast nodules have a <2% likelihood of malignancy, but accelerated growth suggests possible signs of malignancy, i.e., possible breast cancer.
Patients are advised to follow up with regular checkups and to seek further examination and treatment if any abnormality occurs.
