Most people understand breast cancer as something that happens in the breast. However it can metastasise (spread) via lymphatics to nearby lymph nodes usually those under the arm. That is why surgery for breast cancer always involves some type of surgery for the glands under the arm- either axillary clearance, sampling or sentinel node biopsy.
Breast cancer can also spread to other parts of the body via blood vessels. So it can spread to the lungs, pleura (the lining of the lungs), the liver, the brain and most commonly to the bones.
Seventy percent of the time that breast cancer spreads to other locations, it spreads to bone, especially the vertebrae and the long bones of the arms, legs and ribs. Breast cancer cells "set up house" in the bones and form tumors. When breast cancer is found in bones, it has usually spread to more than one site. At this stage, it is treatable, often for many years, but it is not curable.
Like normal breast cells, these tumors in the bone often thrive on female hormones, especially estrogen. Therefore, the doctor often treats the patient with medicines that lower her estrogen levels.
Usually when breast cancer spreads to bone, it eats away healthy bone causing weak spots. The bones break easily at these weak spots. That is why breast cancer patients are often seen wearing braces or using a wheel chair, and why they complain about aching bones. If a patient has had breast cancer in the past and notices pain in the bones, the patient should see a doctor.
