Metastasis in lower respiratory
tract from primary
renal cell carcinoma.
Secondary cancer, also called metastatic cancer, is cancer that has spread from the initial or primary site to another part of the body. The spread of the cancer occurs when the cancerous cells enter the blood and/or lymph system and travel to other parts of the body where they start to grow and multiply within that new area.
Treatment for secondary cancers depends on the location of the original cancer, the treatment regimen that has already been used to treat the primary cancer as well as the size of the secondary cancer.
Treatment for secondary cancer may include one or more of the following options:
- Surgery
- The type of surgery performed to treat the secondary cancer will depend on the location where the cancer has spread. Surgery is not often used to treat the secondary cancer, but rather is used to stop bleeding, pain, prevent bone fractures and/or relieve other debilitating symptoms caused by the spreading of the cancer.
- Radiation Therapy
- Radiation therapy is the use of high-energy rays to kill the cancerous cells. It can be given externally, meaning the radiation stems from a large machine, or internally, where the radiation is placed directly into the body in the area of the tumor. Radiation is usually given to try to shrink the size of the tumor in order to help alleviate pain associated with the metastasis.
- Chemotherapy
- Given intravenously and by pill, chemotherapy works to kill the rapidly dividing cancer cells. Since chemotherapy is not selective in killing just the cancer cells, it can cause several debilitating side effects including hair loss and nausea.
- Hormone Therapy
- In certain cancers male and female reproductive hormones such as estrogen and androgen fuel the growth and spread of the cancer. Hormone therapies block the activation of these particular hormones to try to stop the growth of the cancer.
- Targeted Therapy
- Innovative research over the past decade has yielded a better understanding of how certain genes or proteins stimulate the growth of certain cancers. Most targeted therapies typically receive their first indication to treat cancer that has spread.
- Bisphosphonates
- In secondary cancer, it is not unusual for the cancer to spread to the bones. Therapies called bisphosphonates, which are given intravenously, along with calcium and Vitamin D are given to help prevent fractures by strengthening the bone affected by the spread of the cancer.
