How does chemotherapy work?
Chemotherapy is one of the most effective measures in treating cancer patients. Sometimes it alone can be used to cure some types of cancer. Chemotherapy works well when it’s used in combination of several chemotherapy drugs. During chemotherapy the medicine is swallowed or injected through the veins of patient.
Under chemotherapy the drugs not only target the affected part but also help to eliminate the cancerous cells present anywhere else inside the body.
There are many kinds of chemotherapy drugs that are available in the market and their combination is widely advised as one of the more effective ways to get rid of cancerous cells. This sort of combination of several drugs can fight cancer cells in different ways making cancer cells ineffective or reducing their growth.
Since cancer is uncontrolled production of cells in the body the chemotherapy tries reducing or even stopping that damage by stopping the aggressive growth of the cells and slowing down their capacity to multiply and increase in number. Chemotherapy is given in several sessions depending upon the type and growth of cancer inside the body.
Main chemotherapy features
• It stops the cancer cells from multiplying and increasing
• Assists the immune system for self defense.
• Initiates the growth of essential enzymes in the body.
Each session of chemotherapy is aimed to work in a different perspective to eliminate cancer. Often, combination chemotherapy is preferred so that cancerous cells are attacked in more effectively because each medicine has its own strengths and perform in its own manner. In an early stage, chemotherapy attempts to reduce the amount of cancer cells because it does not allow the cells to multiply.
There can be cases where chemotherapy drugs may alter the normal functioning of healthy cells present in that area. The harm to the healthy cells can be from mild to severe and the side effects should go away once the chemotherapy is over.
Your doctor might advise you for additional chemotherapy even after a tumour had been remove, since surgery alone sometimes not enough to allocate the presence of cancer causing cluster in other parts of the body. These small clusters of cancer cells have sufficient nutrients and enzymes which allow them to grow at rapid speed leading to another cancer in other part or parts of the body.
Chemotherapy uses combination of medicines so that various sensitive organs inside the body may experience less adverse reactions. Some may experience several chemotherapy side effects.
• Mostly a person suffering from cancer looses his or her hair while being on chemotherapy treatment.
• Bone marrow cells may be affected and can cause fatigue and increased risk of infection.
• Skin may become dehydrated and dryness of mouth may be present.
• A person may suffer from diarrhea, vomiting or stomach aches.
