Chemotherapy treatment

 Chemotherapy is a drug treatment that uses powerful chemicals to kill fast growing cells in your body. That's why chemotherapy is used as an treatment for the cancer cells in the patient body, since cancer cell grow and multiply much more quickly than most of cells in our body. It inhibit mitosis (cell division) at specific stages or it induce the DNA damage which will cause the inhibition of DNA repair. 

Their are different ways for applying chemotherapy for the patient which can be taken orally by the mouth or injections use of a short needle in the blood vein, injections given through the skin into the muscle layers or can be given directly into the abdominal cavity and also many other ways depends on the place the cancer cells exist. 

  The efficiency of the chemotherapy depends on the type of the cancer and the stage. 

The chemotherapy treatment made a big change in the treatment of cancer but also it has a negative effect for example when you apply it on part of skin cancer it not only will kill the cancer cell it will also kill the normal one because the cells are very close to each other. Also some cancer cell stay dormant for a while the chemotherapy can't see them or treat them so when they wake up they will become big cancer cell and start to divide, develop, and travel to different part of the human body that's why we hear in some case some patient after the chemotherapy treatment they are affected with the cancer disease again.
