Breast Cancer

In-Depth Analysis

Types of Breast Cancer

  • Ductal Carcinoma In Situ (DCIS)
    DCIS is a non-invasive form of breast cancer where abnormal cells are found in the lining of a breast duct but have not spread outside the duct. It is considered the earliest form of breast cancer and is highly treatable.

  • Invasive Ductal Carcinoma (IDC)
    This is the most common type of breast cancer. It begins in the milk ducts and invades surrounding breast tissue. IDC accounts for about 80% of all invasive breast cancers.

  • Invasive Lobular Carcinoma (ILC)
    ILC starts in the milk-producing lobules and spreads to nearby tissues. It is the second most common type of invasive breast cancer, known for its tendency to be more difficult to detect on mammograms.

  • Triple-Negative Breast Cancer
    This aggressive form of breast cancer lacks estrogen, progesterone, and HER2 receptors, making it harder to treat with standard hormone therapies or HER2-targeted drugs.

  • HER2-Positive Breast Cancer
    Characterized by an overexpression of the HER2 protein, this type grows and spreads faster than other breast cancers but often responds well to targeted therapies like trastuzumab (Herceptin).

  • Inflammatory Breast Cancer
    A rare and aggressive form that blocks lymph vessels in the skin of the breast, causing redness, swelling, and a warm sensation. It progresses rapidly and requires urgent treatment.
