The stage of breast cancer when cancer cells do not remain in the original cancer site and spread out to other parts of the body is called metastatic breast cancer. This is the stage when the cancer is fully advanced. Even if you have been successfully treated for breast cancer, there is a chance that some cancer cells do not die, and later spread out through blood and lymphatic vessels to other body organs. This process is known as metastasis of 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.
Metastasis usually occurs in bones, and organs like lungs and brains. Unfortunately, breast cancer has the highest chance of metastasizing. If you have had breast cancer, and later develop another form of cancer, in all probability, it is breast cancer recurring. The fortunate side of this is that breast cancer is very much treatable. However, if you develop breast cancer again in the breast that was not diseased earlier, it might just be a new cancer.
It is very important to know about metastatic breast cancer because around 30% of women with breast cancer are later diagnosed with metastatic cancer. Metastatic breast cancer is best treatable when no organ, specifically the lungs and brain, develop cancer, or when the cancer cells show traces of estrogen or progesterone hormone receptors, or, when tumors still respond to therapies, or when there have not been many treatments the patient has already availed.
Metastatic breast cancer, owing to its nature, requires extensive treatment. Therapies like chemotherapy, hormonal treatment, immune therapy alone with regular mammograms, ultrasounds, CT scans, MRIs, bone scans etc. are necessary. The treatments can be purpose-specific. For treating the whole body, systemic therapies have to be implemented; for treatment of specific organs, local treatments like mastectomy and lumpectomy are done, and for alleviating pain, therapies along with oral aspirin intake are adopted.
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.
