Chemotherapy is the use of drugs to destroy cancer cells. It usually works by keeping the cancer cells from growing, dividing, and making more cells. Because cancer cells usually grow and divide faster than normal cells, chemotherapy has more of an effect on cancer cells.
he word "chemotherapy" ("chemo") is often used when referring to medicines or drugs that treat cancer. But, not all drugs used to treat cancer work in the same way. Traditional or standard chemotherapy uses drugs that are cytotoxic, meaning they can kill tumor cells. If your treatment plan includes traditional or standard chemotherapy, knowing how it works and what to expect can often help you prepare for treatment and make informed decisions about your care
It targets cells that grow and divide quickly, as cancer cells do. Unlike radiation or surgery, which target specific areas, chemo can work throughout your body. But it can also affect some fast-growing healthy cells, like those of the skin, hair, intestines, and bone marrow. That’s what causes some of the side effects from the treatment
Cure: In some cases, the treatment can destroy cancer cells to the point that your doctor can no longer detect them in your body. After that, the best outcome is that they never grow back again, but that doesn’t always happen.
Control: In some cases, it may only be able to keep cancer from spreading to other parts of your body or slow the growth of cancer tumors.
Ease symptoms: In some cases, chemotherapy can’t cure or control the spread of cancer and is simply used to shrink tumors that cause pain or pressure. These tumors often continue to grow back.
