Types of Breast Cancer

There are several types of breast cancer, including:

Ductal Carcinoma in Situ (DCIS) – This type of breast cancer begins in the milk ducts but has not spread to surrounding tissue. It is considered non-invasive or pre-invasive breast cancer.

Invasive Ductal Carcinoma (IDC) – This is the most common type of breast cancer, accounting for about 80% of all cases. It occurs in the milk ducts of the breast and can spread to other parts of the body if not treated early.

Invasive Lobular Carcinoma (ILC) – ILC begins in the lobules (milk-producing glands) of the breast and can spread to nearby tissues. It is less common than IDC but still accounts for a significant portion of breast cancer cases.

Lobular Carcinoma In Situ (LCIS). LCIS is not considered true cancer but an indication of increased risk for developing invasive breast cancer. It starts in the lobules but does not invade surrounding tissue.

HER2-Positive Breast Cancer. HER2-positive breast cancer occurs when breast cancer cells have an excess of a protein called human epidermal growth factor receptor 2 (HER2). It can be more aggressive but is often treatable with targeted therapies.

Inflammatory Breast Cancer (IBC) – This is a rare and aggressive type of breast cancer that can cause the breast to appear red and swollen.

Triple-Negative Breast Cancer (TNBC) – This type of breast cancer does not have receptors for estrogen, progesterone, or HER2. It tends to be more aggressive and may require different treatment approaches.

The type of breast cancer is an important factor in determining the appropriate treatment plan because each type of cancer behaves differently and responds differently to various treatments. It allows doctors to tailor treatment plans to the individual needs of the patient, improving the chances of successful treatment and reducing the risk of recurrence.
