Understanding Breast Cancer

Breast cancer begins when cells in the breast grow uncontrollably. These cells usually form a tumor. It's the most diagnosed cancer in women worldwide, but men can get it too.

Risk factors include age, genetic mutations (like BRCA1/2), family history, menstrual history, and lifestyle. Dense breast tissue can increase risk and complicate detection.

Breast cancer isn't uniform; types vary molecularly. Invasive ductal carcinoma is most common, but there are also lobular, inflammatory, and triple-negative subtypes, each with unique treatments.

Mammograms can detect cancer early, potentially before symptoms appear. However, false positives are possible, leading to overdiagnosis and unnecessary interventions in some cases.

Treatments have evolved beyond chemotherapy and radiation. Targeted therapy, immunotherapy, and hormone therapy are tailored to specific cancer types, improving outcomes and reducing side effects.

Breast cancer survival has improved significantly, with a five-year survival rate of nearly 90%. Early detection and advanced treatments contribute to these encouraging figures.

Male breast cancer is rare, accounting for less than 1% of all breast cancers. Lack of awareness can lead to delayed diagnosis, emphasizing the need for education.
