Chemotherapy is the use of drugs to aid in fighting off cancer. The pharmacology industry is becoming more and more advanced., because of this the drugs currently used in chemotherapy are safer, and more targeted for specific types of caner. The drugs are more effective and have less side effects than drugs from the past. Today physicians prescribe their cancer patients a "drug cocktail" to help to curb the side effects while providing more effective treatment.
Chemotherapy drugs work by inhibiting the ability of a cell to divide quickly. One of the major characteristics of cancer is that cells grow quickly and out of control by dividing abnormal cells that are located within the cancerous tissue.
Typically chemotherapy is used when a person's cancer is so advanced that it requires an intense and rigorous treatment to eliminate the cancer cells effectively. Cancer cell clumps are capable of growing and spreading to other areas. When this happens it is often a given that chemotherapy is the best solution.
Cancers can recur. The causes are still poorly understood. In some cases it may be that the initial cancer wasn't entirely eradicated. Or, it may be that the underlying cause that generated the tumor is still present and active, causing the cancer to regenerate. But whatever the basic reason, chemotherapy is often used in such cases.
One of the major complications associated with chemotherapy is the side effects. Even though the drugs are beginning to improve, chemotherapy treatments can from time to time affect an individual's healthy cells in addition to the ones that are cancerous.
Since some of that function is to fight disease such as the cancer itself, a double harm occurs. Radiation therapy has a similar drawback in that it compromises the immune system, which is part of what helps to fight the cancer and its effects.
Sometimes an individual will experience issues with their digestive system. Side effects might include nausea, hair loss, and even poor composition of bone marrow. Bone marrow is necessary for a lot of different functions of the body. More importantly it aids in the creation of both red and white blood cells.
Someone undergoing chemotherapy might experience heart, kidney, and other organ damage. This is extremely uncommon because the cells in these organs aren't capable of dividing as frequently under normal instances. In some studies individuals lost their memory and concentration. Older females often find that their reproductive system changes, causing premature menopause.
The chemotherapy drugs used today are easily tolerated and more specific to cancer type than the drugs of the past. They help to cut off vessels responsible for feeding the tumors with blood, and encouraging growth in the vessel. There are many different ways chemotherapy is administered. Each patient has a regimen designed specifically for them.
Though never pleasant, chemotherapy provides an important tool in the fight against what was once an almost always fatal disease. Today, long term survivability is greater than ever with fewer long-term side effects. Chemotherapy is one of the reasons.
