Understanding HER2-Positive Breast Cancer: Early Detection and Treatment
Breast cancer, a broad term encompassing various diseases, requires accurate diagnosis and classification for effective treatment. One such type, HER2-positive breast cancer, affects around 25% of cases and is more common in younger women. Early detection and understanding of this aggressive form of cancer are crucial.
HER2-positive breast cancer is characterised by an overproduction of the HER2 protein, leading to rapid cell growth and reproduction. Diagnosis involves a physical exam, medical history, imaging tests like ultrasounds or mammograms, and a breast biopsy to determine HER2 protein levels. Symptoms may include breast lumps, nipple discharge, breast pain, and skin or nipple changes. Regular screenings and prompt medical consultation are vital for early detection.
Treatment options are extensive and have improved significantly due to advancements in targeted therapies. These include surgery, radiation, chemotherapy, and hormone treatments for cancers that are also HR-positive. Despite its aggressive nature, the outlook for HER2-positive breast cancer patients has been significantly enhanced by these targeted treatments. Risk factors for this non-hereditary condition include being female, delayed childbearing, obesity, sedentary lifestyle, previous chest radiation, and tobacco use.
HER2-positive breast cancer, while more common in younger women, can affect anyone. Early detection through regular screenings and prompt medical attention for unusual symptoms are key. With targeted treatments, the prognosis for those diagnosed has improved significantly, making understanding and awareness of this cancer type crucial.
