Chemotherapy is a powerful treatment for many types of cancer, offering the hope of a full recovery and cure. Chemotherapy is a form of drug treatment that uses powerful drugs to kill cancer cells. The drugs are selected based on the type and stage of cancer and the expected benefit for the patient. Chemotherapy can be used alone or in combination with other treatments such as surgery or radiation therapy.
How Chemotherapy Works
Chemotherapy works by killing cancer cells or stopping their growth. The drugs used in chemotherapy can either be taken orally or injected directly into the cancer cells. They travel through the body to target and destroy cancer cells. Chemotherapy drugs are designed to kill rapidly dividing cells, which is how cancer cells grow and spread. Unfortunately, they also affect healthy cells that divide rapidly such as those in your bones, mouth, intestines, and hair follicles. This is why some of the most common side effects of chemotherapy are hair loss and fatigue.
Benefits of Chemotherapy
The primary benefit of chemotherapy is that it can destroy cancer cells and stop them from spreading. It can help shrink tumors and make them easier to remove with surgery. This can also be combined with other treatments such as radiation therapy, hormone therapy, and immunotherapy to get the best possible outcome. Chemotherapy can also be used as a preventive measure to reduce the risk of cancer recurrence or to prevent the spread of existing cancer.
Risks of Chemotherapy
Though chemotherapy can be very effective, it can also have side effects. Some of the most commonly experienced side effects include hair loss, fatigue, nausea, and an increased risk of infection. Chemotherapy can also affect long-term health, causing changes in heart and lung function or changes in the immune system that can make it more difficult to fight off infection and disease.
When is Chemotherapy Used?
Chemotherapy can be used in conjunction with surgery and/or radiation, or it can be used alone, depending on the circumstances. It is most often used in advanced stages of cancer when the cancer has spread to other parts of the body. It is also used in some cases before surgery to shrink the tumor, making it easier to remove with surgery.
Chemotherapy is a powerful treatment option for many types of cancer, but it is not without risks. It is important to weigh the benefits and risks of chemotherapy before deciding to pursue it. Your healthcare team should work with you to assess your needs and discuss the benefits and risks of chemotherapy as part of a comprehensive treatment plan.
