CA15-3 is a tumor marker utilized for detecting breast cancer, and its abnormal elevation may be associated with the presence and progression of the disease. However, it is important to recognize that an elevated CA15-3 level does not definitively indicate breast cancer, as other factors can also lead to such an increase.

In a detailed analysis, it is essential to understand that CA15-3 is a glycoprotein predominantly found on the surface of certain cancer cells. Approximately 50%-60% of individuals with breast cancer exhibit elevated CA15-3 levels. Furthermore, increased CA15-3 levels can also be linked to other types of cancer, including ovarian, lung, and colon cancers. Thus, if CA15-3 levels are elevated, additional examinations are required to ascertain the presence of cancer or other underlying conditions.

Apart from cancer, other factors such as liver diseases, autoimmune diseases, and pregnancy can also result in elevated CA15-3 levels. Consequently, interpreting an increase in CA15-3 levels necessitates a comprehensive consideration of the patient's medical history, physical examination findings, and other laboratory test outcomes.

To prevent breast cancer in daily life, it is advisable for women to conduct regular self-breast examinations and follow their physician's recommendations for breast cancer screening. Should symptoms like breast lumps, skin alterations, or nipple discharge arise, prompt medical attention is warranted. For patients diagnosed with breast cancer, adhering to the treatment regimen prescribed by their doctor, along with regular follow-ups and monitoring of CA15-3 level fluctuations, is crucial for timely adjustments to the treatment plan.
