Breast Cancer is a type of cancer that begins in the cells of the breast, typically in the ducts or lobules. It occurs when abnormal cells grow uncontrollably, forming a tumor that can spread to nearby tissues or other parts of the body (metastasize). Symptoms may include a lump in the breast, changes in breast shape or size, and unusual skin changes. While the exact cause is not always clear, risk factors include genetics, age, hormone exposure, and lifestyle. Early detection through screening and advances in treatment have improved survival rates, making breast cancer one of the most treatable cancers when caught early. 

• Gender: Women are significantly more likely to develop breast cancer than men, though men can still get it. 

• Age: The risk increases as a person gets older, with most cases diagnosed in women over 50. 

• Family History: A family history of breast cancer, especially in a first degree relative (mother, sister, daughter), increases risk. Inherited genetic mutations, such as those in the BRCA1 or BRCA2 genes, can also heighten risk. 

• Personal History: Individuals who have had breast cancer or certain benign breast conditions in the past are at higher risk of developing it again. 

• Hormonal Factors: Early menstruation (before age 12), late menopause (after age 55), or long-term use of hormone replacement therapy can increase the risk due to prolonged exposure to estrogen. 

Breast Cancer is diagnosed through a combination of methods. The process typically begins with a physical exam to check for lumps or changes in the breast. Mammography (X-ray) is the most common screening tool used to detect early signs of cancer, especially in women over 40. If a suspicious area is found, ultrasound or a breast MRI may be used for further evaluation. A biopsy is the definitive method to confirm cancer, where a sample tissue is taken for examination. Additional blood tests and genetic testing may help assess overall health or identify inherited cancer risks. If cancer is confirmed, further imaging tests like CT scans or bone scans are used to determine if the cancer has spread, which is essential for staging and treatment planning.
