Breast Cancer: Classification, Risk Factors, Current Diagnostic Procedures and Therapeutics

Abstract

The aetiology of breast cancer is complicated. In population health, breast cancer significantly impacts the most typical invasive malignancy and the second most typical death source for women. The most crucial point for the best prognosis is identifying early-stage cancer cells. The conventional diagnostics test for breast cancer includes a physical examination, biopsy (Fine-needle aspiration biopsy, core needle biopsy, Surgical biopsy) and several imaging techniques like mammography (digital mammography, computer-aided detection and breast tomosynthesis), MRI (Magnetic Resonance Imaging). Several drugs are approved by Food and Drug Administration for breast cancer, among them, some are approved to prevent breast cancer; some are used to treat breast cancer and some drugs are used in combination mode. Clinical investigation reports revealed that breast cancer mortality decreased in association with smaller breast volume and hence to meet the goal exercise is highly recommended. Similarly, dietary fat has been proposed as one of the etiologic factors of breast cancer. Obesity, overweight and reduced physical activity, causes breast cancer. At an early stage, cancer detection could increase breast cancer survival rates significantly in the long term. In the present review we have represented the breast cancer, its current statistics, molecular classification, different causes, disease prognosis, diagnostic strategies, and management in details in a lucid way.
