Infiltrating ductal carcinoma of the breast and its characteristics

Infiltrating ductal carcinoma of the breast is a malignant tumor of the breast that develops from cells of the tissues of the ducts of the mammary glands of women. Most often the disease occurs in women of Mature age, especially over 50.


Reliably determine the reasons for the development of neoplasms of the mammary glands is not known but factors that are the instigators of the development of infiltrating carcinoma in women:

  • ozhirenienever advancing pregnancy or pregnancy after the age of 30-35;
  • obesity, hypertension, diabetes mellitus;
  • early menstruation or late menopause in women;
  • breast cancer in close relatives of women;
  • hormone therapy or hormonal contraception for a long time;

  • harmful and unfavorable production environment;
  • diseases of the endocrine system.

Types of breast cancer

Cancer is a group of malignant tumors. Depending on the many signs there are several types of cancer (size, location, growth characteristics of education, presence of metastases, etc.). Depending on these parameters, the choice of treatment tactics and also depends on the prognosis of the disease.

Infiltrating carcinoma is divided into two types:

  • infiltriruushaya karcinoma intraductal;
  • lobular.

There is also the classification for which the carcinomas are divided into:

  • carcinoma, developed from fibroadenoma;
  • squamous;
  • papillary;
  • lattice;
  • medullary;
  • lobular;
  • mucosa;
  • Paget's disease.

To ductal or lobular cancer is necessary to estimate the aggressiveness of the growth of education. Most carcinomas of the breast (about 80%) is characterized by growth into the surrounding tissue.


Dependent on the severity of the disease, there are 3 degrees of malignancy of carcinoma of the breast:

  • 1 degree – 3-5 points;
  • Stage 2 – 6-7 points;
  • Grade 3 – 8-9.

The calculation of points takes place on the grounds of education, tubule, mitosis, nuclei hyperchromatism.

Prognosis five-year survival rate of patients with 1 degree of malignancy carcinoma of the breast is 75-81%. Infiltrating carcinoma of the breast 2 degrees is characterized by a 54% survival rate, while 3-grade carcinoma could be only 34%.

Symptoms of breast cancer

In addition, as the treatment are radiation therapy and chemotherapy. As the comprehensive treatment may be applied modern methods of treatment of disease – targeted therapy and immunotherapy.
