Are breast cancer and brain cancer related


Breast cancer is a common cause of brain metastases, with metastases occurring in at least 10–16 % of patients. Longer survival of patients with metastatic breast cancer and the use of better imaging techniques are associated with an increased incidence of brain metastases.Nov 24, 2015


How does breast cancer spread to the brain?

suggests that it can happen when breast cancer cells get into the circulatory system. Some breast cancer cells have or develop the ability to grow and spread in the brain after they cross the blood-brain barrier. When these cells adapt to the environment of the brain, they can multiply and result in brain metastases.

People with breast cancer have a higher risk of blood clots. Their risk is higher because of the cancer itself and some treatments for breast cancer. You may be at risk of a blood clot forming known as a deep vein thrombosis (DVT). People with a DVT are at risk of developing a pulmonary embolism.

What cancer cells have spread to the brain?

The cancer cells that have spread to the brain are breast cancer cells.

For some people, the brain may be the only area of secondary breast cancer. 2.

Risk Factors/Causes

  • Nobody is sure why some people develop brain metastases and others do not. We do know of some risk factors, however. Brain metastases are more likely in young women with breast cancer, and the incidence is exceptionally high in those diagnosed before the age of 35. Tumors that are more likely to spread to the brain include those with a higher tumor grade, those which are HER…

  • MRI is the most commonly used imaging technique to detect brain metastases; CT scans of the head may be used for those who are unable to have an MRI performed (for example, those with pacemakers), but CT scans are less effective in determining the presence of brain metastases. The diagnosis is usually made based on imaging findings and a history of breast cancer, but a bi…

Local Options

  • Local treatments are those designed to treat the brain metastases specifically and are most often recommended if brain metastases are causing significant symptoms, or if only a few metastases are present with the goal to eradicate the metastases. When many metastases are present, the goal is to reduce symptoms (palliative). With only a few metastases, eradication of the metastas…
