BREAKTHROUGH IN BREAST CANCER DETECTION

Why in the news?

Researchers at CSIR-CCMB, in collaboration with RCC Thiruvananthapuram, have developed a groundbreaking method to detect various types of breast cancer using just a drop of blood.
The discovery leverages microRNA signatures to identify potential biomarkers for different stages and types of invasive breast carcinoma.

Scientific Breakthrough:

Analysis of microRNA profiles identified 107 potential biomarkers for invasive breast cancer, paving the way for a cost-effective, non-invasive liquid biopsy method crucial for early detection in resource-limited settings.

About Brest Cancer

Nature of Breast Cancer:

Breast cancer involves abnormal growth of cells in the breast, forming tumours that can potentially spread throughout the body if untreated.

Development and Progression:

Originating in milk ducts or lobules, early-stage breast cancer (in situ) is non-life-threatening and detectable. Invasive forms spread to nearby tissues, causing lumps or thickening.

Risk of Metastasis:

Advanced stages involve metastasis, where cancer cells spread to lymph nodes or other organs, posing life-threatening risks.

Treatment Approaches:

Treatment varies based on individual factors, cancer type, and spread, typically involving surgery, radiation, and medications tailored to manage and eradicate cancer cells.
