Introduction:Triple-negative breast cancer (TNBC) is a subtype of breast cancer that is characterized by the absence of estrogen receptors, progesterone receptors, and human epidermal growth factor receptor 2 (HER2). Unfortunately, TNBC has a higher mortality rate compared to other breast cancer types. Identifying the early signs and symptoms of TNBC is crucial for timely diagnosis and effective treatment. This article discusses the common symptoms associated with triple-negative breast cancer that patients and healthcare professionals should look out for.1. Breast Lump or Mass:The most common symptom of TNBC, as well as other types of breast cancer, is the presence of a lump or thickened tissue in the breast. This lump may feel different from surrounding breast tissue, such as being harder or irregularly shaped. However, it is important to note that not all breast lumps are cancerous, but they should be evaluated by a healthcare professional.2. Changes in Breast Appearance:Triple-negative breast cancer may cause changes in the size, shape, or appearance of the breast. Dimpling, puckering, or redness of the skin, as well as nipple inversion or discharge, may also indicate the presence of TNBC. Any unexplained changes in the breast should be examined by a doctor.3. Breast Pain or Discomfort:While breast pain is a common symptom experienced by many women during their menstrual cycle, persistent or new-onset breast pain or discomfort can be a warning sign of TNBC. Patients should seek medical attention if they experience persistent breast pain that is not related to their menstrual cycle or other known causes.4. Swollen Lymph Nodes:TNBC can cause the lymph nodes near the affected breast to become enlarged or feel tender to the touch. Lymph nodes are an essential part of the body's immune system and their enlargement may indicate the spread of cancer cells. If swelling and tenderness in the lymph nodes are observed, prompt medical evaluation is necessary.5. Changes in Overall Well-being:In some cases, patients with TNBC may experience unexplained weight loss, fatigue, or general malaise. These symptoms can occur as a result of cancer affecting the body's metabolism or due to the body's immune response. If such symptoms persist or worsen, it is advised to consult a healthcare professional.Conclusion:Triple-negative breast cancer is a highly aggressive subtype of breast cancer. Recognizing the symptoms associated with this condition is vital for early detection and improved outcomes. Women who notice any abnormalities, such as breast lump or mass, changes in breast appearance, persistent breast pain, swollen lymph nodes, or changes in overall well-being, should promptly seek medical advice. Early diagnosis and appropriate treatment significantly increase the chances of successful management of triple-negative breast cancer.
