The Approach to Care of Cancer Research

Cancer is one of the most problematic and dangerous diseases in the modern world, and it does not really depend upon either age or ethnicity or religion of an individual. All people are afraid to be diagnosed with cancer. Cancer could start in any part of human body. Bad and toxic cells start to grow and unite into one crowded corrupted cell, which the human body is not able to cope with. The paper will continue considering diagnosis and staging of care, complications of the disease and possible side effects of the treatment, finally focusing upon approaches to cancer care. The Approach to Care of Cancer Research

Diagnosis and staging of cancer
Cancer is difficult to diagnose. There are a lot of types of cancer, cancer could start in one or multiple organs at a time and it is able to spread. Correct diagnosis is certainly the first step towards corresponding staging and treatment of cancer. In case a doctor obtains the results of screening test, which suggest cancer, he would continue to investigate the causes of these results. In this case lab tests, scans and other tests are ordered. In case the lab tests show that there are either high or low levels of certain substances in human body, then it could be interpreted as a cancer threat. Lab tests are applied in order to find those substances in blood, urine or other body fluids. Lab tests are important, but doctors do not rely purely upon their results, when they are to diagnose cancer. There is a list of imaging procedures, which help to create pictures of certain areas of the body so that the doctors could see where the tumor is present. Such pictures are made with the help of nuclear scan, CT scan, MRI, ultrasound, X-Ray, PET scan. Often doctors also do biopsy in order to diagnose cancer. Biopsy is the procedure of removing of a sample of tissue from the patient. Then this sample is passed to a pathologist for further check with the help of a microscope. Doctors make biopsy, using different methods. Tissue or fluid could be withdrawn with a needle. Endoscope, which is a thin and lighted tube, could be used for looking inside the body of the patient. It is inserted in natural opening, usually mouth, and then the tissue is removed with the help of special tools. Excisional or incisional surgery is one more method for biopsy. In the first case the complete tumor is removed and even some good tissues around it. In the second case only some part of the tumor is removed by the surgeon. The Approach to Care of Cancer Research
