The Most Invasive Common Breast Cancer
Infiltrating ductal carcinoma better known as invasive ductal carcinoma is the most common of all breast cancers affecting about 80 percent of all breast cancers. Invasive refers to the fact that the cancer has invaded other breast tissue meaning it has spread beyond its point of origin. Invasive ductal carcinoma began in the ducts that are the pipes that carry the milk from the lobules (the milk producing glands) to the nipples. Carcinoma is any kind of cancer that originates in the tissue, which covers the lining of the organs. Therefore infiltrating ductal carcinoma is a cancer that has broken through the wall of the milk ducts and as now spread out to other parts of breast tissue. Over time, left untreated it can enter the lymph nodes and then spread to other parts of the body.
Prevalence of this cancer
The American Cancer Society reports that over 180,000 new cases of invasive breast cancer is reported every year in America. Most of these cases are invasive ductal carcinoma. Invasive ductal carcinoma will attack women of any age, however it is more common among older women. About two thirds of all women who are diagnosed with invasive ductal carcinoma are women who are over 55 years old. In addition men can also suffer from invasive ductal carcinoma.
Symptoms of invasive ductal carcinoma
In the beginning stages of this cancer, there may be no signs at all, making it very difficult for an early diagnosis. Often it is an abnormal x-ray (mammogram), which prompts the need for further testing.
In other cases you, or your doctor will notice a lump in the breast during a physical breast examination. The American Cancer Society notes the following signs as first indicators of invasive ductal carcinoma: swelling in any part, or the entire breast, skin irritation in the breast area, dimpling, pain in the nipple, inverted nipple, redness or scaly skin in the breast or nipple, discharge from the nipple, or a lump in the underarm area.
