What is Breast Cancer?
Breast cancer is a type of cancer that forms in the cells of the breasts. It can affect both men and women, although it is far more common in women. This condition occurs when the cells in breast tissue begin to grow uncontrollably, leading to the formation of a tumor.
Types of Breast Cancer
There are several types of breast cancer, with the most common being:
- Invasive Ductal Carcinoma: This cancer starts in the milk ducts and invades surrounding tissue.
- Invasive Lobular Carcinoma: This cancer begins in the lobules, the glands responsible for producing milk.
- Ductal Carcinoma in Situ (DCIS): A non-invasive type where cancer cells are contained within the ducts.
Risk Factors
Several risk factors may increase the likelihood of developing breast cancer, including:
- Age
- Family history of breast cancer
- Genetic mutations (e.g., BRCA1 and BRCA2)
- Hormonal factors
Awareness and Early Detection
Breast cancer awareness is crucial for early detection. Regular self-exams and mammograms can significantly improve treatment outcomes by catching the disease in its early stages.
