Staging is essential in determining the choice of therapy and assessing prognosis. A cancer s stage is based on information about the primary tumor s size and location in the body and whether or not it has spread to other areas of the body. A number of different staging systems are currently being used to classify tumors. If cancer cells have spread, the cancer is considered invasive and falls in the summary staging of local, regional, or distant. Treatment options may include surgery, radiation, chemotherapy, hormone therapy, and immunotherapy.
Chemotherapy is the use of drugs to treat cancer.
Systemic chemotherapy uses anticancer drugs that are usually given into a vein or by mouth to enter the bloodstream and reach all areas of the body. Hormone therapy is treatment with hormones, drugs that interfere with hormone production. Immunotherapy is the use of treatments that promote or support the body's immune system response to a disease such as cancer. Limitations will vary among individuals. Also note that not all people who have cancer will need accommodations to perform their jobs and many others may need only a few accommodations.
