Q:What is Chemotherapy?
Dr:Chemotherapy refers to the usage of drugs to treat a disease, but over time it has come to be a term specific to cancer treatment. There are different types of drugs for different types of cancer cells. Each drug as a particular method of administration and schedule.
Q:How does Chemotherapy help treat cancer?
Dr:The drugs used for chemotherapy slow and stop the growth of cancer cells. The drugs recognise cancer cells because they grow and multiply rapidly in comparison to normal cells. However, there are some healthy cells that reproduce quickly as well like the hair cells and the cells that line the digestive tract – chemo drugs attack these cells as well. This is one of the reasons for side effects such as hair loss and low blood count during chemotherapy.
Q:Is curing cancer the only goal of Chemotherapy?
Dr:Cure, is definitely the primary goal of Chemotherapy. If there is a possibility of curing cancer with chemotherapy, then the treatment is given with curative intent. However, it is not always the case and that is why chemotherapy is given in tandem with radiation therapy. Control is another goal of Chemotherapy because the drugs can be used to shrink the tumour or to slow down/ stop the growth of cancer. Chemotherapy can also be used to ease the symptoms of cancer. This usually occurs when cancer has advanced and cannot be controlled. Chemotherapy
Q:How are Chemotherapy drugs administered?
Dr:Most chemo drugs are administered intravenously through a tube – one end is connected to a bag that contains the drug, and the other end is connected to a vein in the patient’s arm. In rare cases, chemo drugs are in the form of a pill or liquid which can be swallowed, and in some cases, the medicine is injected into the body as an intramuscular injection.
Q:Is Chemotherapy painful?
Dr:Since chemo drugs are usually administered via IV drip, most people do not find it painful. The discomfort and pinch felt during inserting the IV needle may continue for a few days, but eventually, the patient overcomes that as well.

Q:How many chemotherapy sessions will I need?

Q:Is there anything I can do to improve the effectiveness of chemotherapy?
Dr:The effectiveness of Chemotherapy depends entirely on the type of cancer, what stage it is in and where it is located. There is not much one can do to ensure the treatment works. Some studies state that exercise increases blood flow to the tumour, which increases drug delivery. However, before starting an exercise regimen during chemotherapy, discuss with your doctor about what level of exercise is permissible. Before a session get good rest, drink enough fluids, and remember you might experience nausea so have relevant medication at hand, and stay positive. Read a book, listen to music or meditate during the session to keep calm.
