Q. What is metastasis lung cancer?
Doctor Answer is medically reviewed by SecondMedic medical review team.
Metastasis lung cancer is a form of cancer that has spread from the primary site (where it originated) to other parts of the body. It is a serious and potentially life-threatening condition, and usually requires aggressive treatment.
Metastasis means that the cancerous cells have broken away from the original tumor and travelled through the bloodstream or lymphatic system to other organs or areas of tissue in the body. This can make it much more difficult to treat since individual tumors may be located in multiple different places, making them harder to remove completely. In addition, metastasis can also occur when abnormal cells migrate from one organ directly into another organ -- this happens most commonly with lung cancer but can happen with any type of malignancy.
The exact cause for metastasis is still unknown but some risk factors include age, race, smoking history and genetic predisposition for certain types of cancers such as bladder or cervical cancer. Treatment for metastatic lung cancer includes chemotherapy, radiation therapy and/or surgery depending on where exactly the tumors are located within an individual's body. Unfortunately despite these treatments prognosis remains dismal due to its advanced stage when diagnosed; however there are new therapies being developed which may help increase survival rates in patients with this form of lung disease in future years ahead!
