Metastatic breast cancer is the most advanced stage of breast cancer. Even after treatment, some cancer cells may not die and continue multiplying. These cells may spread to other parts of the body through blood or lymphatic vessels and start the development of cancer in those areas. This stage of the cancer is called metastatic breast cancer.
Metastasis can occur due to three reasons. The first reason has already been stated, that is, when some cancer cells escape from treatments and make cancer recur. The second is when, during a treatment, the cancer goes on advancing, and starts developing tumors in other organs, and sometimes, when cancer is diagnosed so late due to carelessness of the patient or inefficiency of medical professionals, that it has already metastasized to other parts of the body.
Unfortunate as it may be, breast cancer has the maximum chances of metastasizing. When this happens, bones, and organs like the lungs and brain starts showing abnormal changes, which means they’re starting to develop cancer cell growth. If you get lung cancer or liver cancer or any other cancer after getting breast cancer, it is probably just breast cancer metastasis and not a new cancer. This is good news, since breast cancer has low mortality rates and can be treated. However, if the new cancer if in the breast which did not have cancer previously, it may be a new cancer.
Metastatic breast cancer develops in almost thirty out of hundred women who have had breast cancer, which makes knowledge about it so necessary. When the cancer has not metastasized to organs like the lungs and brain, or when there is a presence of estrogen and progesterone hormones in cancer tissues, the cancer is treatable. Also, if you have already not undergone many treatments for your previous cancer, and the malignant cells show some change after therapies, your treatment can be successful.
For treatment of metastatic breast cancer, chemotherapy, immune therapy, hormone treatment, radiation therapy, regular mammograms, bone scans, ultrasounds, PET scans, MRIs, CT scans, etc. are adopted. The treatment is extensive, and involves a lot of specialists. The treatments also vary according to their purpose. There are systemic treatments (like anti-estrogen and chemotherapy) that concentrate on curing every part of the body, local treatments (like surgeries on the lines of mastectomy and lumpectomy and radiation therapy) which focus on curing and killing the cancer in specific areas where the cancer has spread to, and treatments which are focused on just relieving the pain of the victim.
Because metastatic breast cancer means cancer spreading to various parts of the body, complete sure is very difficult. There will come a point when you will have to stop undergoing treatment, even when your cancer is not fully cured. You have the choice of being treated indefinitely, but you have to know, the more number of therapies you take, the more the side-effects are. Also know that many women have lived fruitful lives while taking the treatment for the metastatic disease. It is hard to take decisions when your life is at stake, but it is also necessary that you do it. There is research going on for prolonging lives of people who have this disease, and that research will surely help you.
