What is systemic chemotherapy?
Systemic chemotherapy is an access to chemotherapy, where drugs allow to travel throughout the body to eradicate cancer rather than being applied directly to cancer for targeted therapy. The delivery method suitable for the patient depends on cancer and the situation. Patients with cancer will meet oncologists to discuss treatment options and create the most effective treatment plan. Treatment usually includes several forms of treatment to attack cancer from several angles. Intravenous drugs go directly to the bloodstream and are often highly concentrated. Oral drugs are absorbed by the patient's digestive tract and eventually reach the blood. As medicines move through the body, they attract to suspect cancer cells and destroy them or indicate them to destroy the body.
One problem with systemic chemotherapy is the high probability of damage to the collateral. These drugs cannot distinguish between good, neutral and bad cells and can cause cellular death in healthy cells as they attack cancer cells. It canthat result in significant side effects for the patient, including side effects, such as extreme fatigue, bone marrow exhaustion and chronic nausea and vomiting. The drugs are carefully calibrated to achieve balance between insufficient cancer cells, because the drugs are too weak and pulled out too many healthy cells because the drugs are too strong.
This type of chemotherapy can be recommended when metastasis cancer or there are concerns about metastases and when it is not possible to supply targeted drugs directly to the tumor. Chemotherapy may include a combination of drugs supplied in cycles or a single drug depending on the nature of the cancer. Surgical treatment of tumors and radiation at target tumors can also be included in cancer treatment.
Systemic chemotherapy can be very toxic. Patients are usually given treatment in clinical environment in case ofthat they experience complications requiring medical intervention. If treatment is used at home, patients are carefully recommended about side effects and it is recommended to call doctors if they begin to feel complications. Medicines are also carefully controlled because they can be very dangerous for people who do not have cancer.
The success rate with systemic chemotherapy is very variable. Some cancers respond very well to chemotherapy and treatment may be of therapeutic nature. Others are highly aggressive and chemotherapy can be intended primarily as palliative measures to increase the patient's comfort without actually eradicating cancer.
