Doctors and experts alike feel that for the majority of breast cancer cases, chemotherapy isn’t always the best treatment choice. For the women it is right for, chemotherapy is capable of providing results that are both long term and effective.

Chemotherapy involves using drugs to fight off cancer. As the pharmacology industry becomes more advanced, the drugs used in chemotherapy are now safer, more targeted for specific cancer types, have a greater level of effectiveness, and also have far fewer side effects as drugs utilized in the past. Today, using a drug cocktail is typically used to curb an individual’s side effects and providing treatment that is more effective.

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.

Chemotherapy is often chosen when the cancer has become more advanced, requiring more a rigorous response to eradicate cancer cells. Cancer cells clumps can grow and metastasize (spread of a primary tumor to other areas, forming secondary tumors of similar type). That condition may indicate that chemotherapy is an appropriate regimen.

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 most noted complications that comes with chemotherapy is the side effects. Even through drugs used in cancer treatments are beginning to improve, chemotherapy treatments can often affect a person’s healthy cells and not just the ones that are cancerous.

Radiation also has its shortcoming, it reduces the health of immune system which is need to fight cancer.

The digestive system is often affected in negative ways, leading to nausea, common among those undergoing chemotherapy treatments. Hair loss is a by-now familiar effect. But chemotherapy can even affect the composition of bone marrow, which leads to a number of harmful effects. Bone marrow performs several functions in the body. Foremost among them is aiding in the production of 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.

Still, drugs in use today are better tolerated and more targeted that those of previous generations. They may help cut off vessels that supply blood to the tumors which encourage the growth of just such vessels to feed themselves. There are a variety of chemotherapy regimens, with each one designed for the individual patient and his or her circumstances.

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.
