Invasive Ductal Carcinoma Definitions - Breast cancer is a malignant tumor that grows in the breast tissue. Cancer can begin to grow in the milk glands, milk ducts, fatty tissue and connective tissue in the breast.
There are several types of breast cancer
Carcinoma in situ
Carcinoma in situ means that the cancer is still in place, an early cancer that has not spread or slip out of place of origin.
Ductal carcinoma derived from cells that line the channel leading to the nipple. Approximately 90% of breast cancer is ductal carcinoma. This cancer can occur before or after the menopause. Sometimes this cancer can be palpated and the mammogram, the cancer appears as small spots of calcium deposits (microcalcifications). This cancer is usually limited to certain areas of the breast and can be removed surgically overall. Approximately 25-35% of patients with ductal carcinoma will develop invasive cancer (usually in the same breast).
Carcinoma lobuler began to grow in the mammary gland, usually occurs after menopause. This cancer can not be felt and not seen on a mammogram, but is usually found incidentally on the mammogram is done for other purposes. Approximately 25-30% of patients with carcinoma lobuler will eventually invasive cancer (in the same breast or the other breast or in both breasts).
Invasive cancer is cancer that has spread and damage other tissues, can be localized (confined to the breast) or metastatic (spread to other body parts). Approximately 80% of breast cancers are invasive ductal cancer and 10% were lobuler cancer.
Cancer is derived from the mammary gland.
