Why Are Different Chemo Drugs Used on Different Cancers?

cancer comes in all shapes, sizes and locations. This can affect bone cells, bone marrow, the lungs or even the brain. There is one type of cancer cells, because they all start in different places.

Cancer cells are caused by mutations in the DNA of healthy cells. When a cell goes to divide, and then create new cells of the same species, a new cell has a mutated DNA and a little lost in the steps. One of the most common things that gets lost is the DNA that tells cells how often to share and make new cells. As a result, these mutant cells, regardless of their location, will be divided on what they want to pace. Typically, they divide too quickly and thus became a fast growing tumor.

Although the procedure for the formation of any cancer has to do with the gene mutation, mutation is different in any location. In addition, the original cause of the mutation is different, depending on location. And while every cell cancer involves a rapidly dividing cells that form the tumor becomes more aggressive in its growth, not all tumors were created in the same way.

Some tumors are formed as a result of exposure to toxic agent which is known as a carcinogen. Other cancers caused by family history of cancers. Other tumors only form and no one is quite sure why. Overall, there is no way that all cancer cells are the same.

Given the wide diversity in the type of cells that originally formed a tumor and a wide variation in the whole body, there obviously needs to be different chemotherapy drugs for the treatment of various cancers.

There are two colds are the same and so there is a huge variety of different cold medicines available to people. The same principle applies here. In many cases, the doctor will give a person a variety of drugs that had a history of cancer. Nobody can predict how an individual tumor will respond to certain drugs. Instead try one kind of drug at a time until the doctor finds one that works, doctors just throw everything on the tumor.

Trying one drug at a time until something is found to much time to tumor growth, unless it is first or second medication tried to work very well. This reduces the chances of survival and conquest of cancer.
