What is Breast cancer?

13:33 - 9 April , 2021


As all cancers, it originates when abnormal cells begin to develop disorderly In this case, it is possible that it starts in different areas of the breast such as the ducts, lobules, or surrounding tissue. 

The lobules are responsible for producing milk and the ducts for carrying it to the nipples.

Most breast cancers originate in these parts, although it is possible that they spread to other localized areas of the body by invading the circulatory and lymphatic systems. When it spreads it causes metastasis.

Most common breast cancers:

  • Ductal carcinoma: appears in the breast ducts and usually remains within the breast, although it may metastasize.
  • Lobular carcinoma: starts in the lobules and can spread to other areas of the breast or metastasize.

Signs and symptoms Breast cancer

They are different in each person, but the most frequent are:

  • Breast or armpit lump.
  • Swelling or sinking in the breast or nipple.
  • Changes in color or dryness in the breast.
  • Abnormal discharge from the nipple.
  • Changes in breast shape.
  • Localized pain.

These symptoms can also occur with other conditions, not just cancer. But, if you identify any, see immediately your ABC doctor.

Diagnostic studies 

To detect it, tests such as ultrasound, mammography, MRI of the breasts, and breast tissue biopsy are usually performed. 

Diagnosis and treatment Breast cancer

If you are diagnosed with breast cancer, we will perform other tests to find out if the cancer remains in the breast or has spread. The type and stage of the cancer indicate which treatment you require, but more than one is usually necessary:

  • Surgery: the tumor is removed.
  • Chemotherapy: medicines are used to destroy cancer cells.
  • Radiation therapy: radiation is used to attack cancer cells.
  • Hormonal therapy: blocks the production of hormones required by cancer cells for their development.
  • Biological therapy: strengthens the immune system to eliminate cancer cells.

At ABC Medical Center, doctors from different specialties work together to treat breast cancer, so a highly specialized team of surgeons, oncologists, and radiologist oncologists will treat you with the warmth and humane treatment that sets us apart.
