When diagnosing cancer a series of different tests are used. According to the ACS, “The signs and symptoms will depend on where the cancer is, how big it is, and how much it affects the organs or tissues. If a cancer has spread, signs or symptoms may appear in different parts of the body” (2012). That’s true for the most part, but sometimes cancer can be where it shows no signs or symptoms until it gets much bigger and in the later stages of the disease. The ACS goes on to say that, Cancers of the pancreas, for example, usually doesn’t cause symptoms until they grow large enough to press on nearby nerves or organs (this causes back or belly pain).
Thus, it is essential that the technician inputs the mathematical formula correctly because too much radiation can cause the patient to get sick, depending on how long or the amount of gamma radiation is exposure to the patient. Some types of radiation are not harmful, such as the radiation used to kill cancer cells in the anatomy of a patient; this type of radiation to project bones would be bad if the formula is not
gov/cancertopics. experience, you don't usually go to the doctor until it is probably too late for any type of surgical procedure to remove the tumor/s. By this time either the pain has increased so significantly you are rushed by squad and the only means is palliative. Of course you go through all the tests such as liver function, complete blood counts, ultrasounds, many, many ultrasounds. Then there will be a biopsy to determine between a primary and a cancer that has spread from another organ.
Jenevie Kalvarini Ryan Gallagher Chemistry H 7/15/13 In the article “Sniffing for cancer” by Stephen Ornes he states there’s a new surgical tool that offers surgeons speedier diagnosis of tissues that are cancerous. This new surgical tool is called the “iKnife”. As of now the same procedure can be done by a human but it can take up to thirty minutes, on the other hand it can be accomplished by iKnife in just three seconds. A tool like an iKnife can prevent leaving any diseased cells behind and eliminating chances of causing a new tumor which consequently, will lead the disease to spread. Surgeons usually use electric currents to get rid of these diseased cells instead of using a sharp blade to cut them out.
The most commons defects are found in the BRCA1 gene and the BRCA 2 gene. These genes normally produce proteins that protect you from cancer. If a parent passes you a defective gene, you have an increased risk for breast cancer. Informative 2 B. BRCA1 and BRCA2 are human genes that belong to a class of genes known as tumor suppressors. Genetic tests are available to check for BRCA1 and BRCA2 mutations.
“The ability to make precise genetic changes in human stem cells could be used to boost their therapeutic potential or make them more compatible with patients’ immune systems.” (Wexler 13) This achievement has set more boundaries to therapeutic cloning making funding for clone experiments dispensable. Surely, Therapeutic Cloning is a subject that should be left alone for the safety of our future generations and because it is option to an advancement in medicine not the only solution for mankind. Cloning is the type of technology that humans are not ready to face. Cloning comes with a lot suffering to the clones themselves. Clones would not have their own purpose in life or originality.
The Ethical Issues of Using Monoclonal Antibodies and Vaccines There is a great variety of diseases that causes illness and death to human. So, we have usage of monoclonal antibodies and vaccines. Antibodies are produced by B cells when the body is invaded by non-self material. Each antigen of the material will induce a different B cell to multiply and clone it self as to promote the most efficient way to kill the antigen. When a single type of antibody can be isolated and cloned, these antibodies are known as monoclonal antibodies.
The immune system work against the body a foreign virus enters the body; the body make antibodies to fight of the infection, but the immune system eventually work against itself by helping to destroy the myelin around the axons. The white matter of the brain and spinal cord are scared because of MS. What causes multiple sclerosis is a mystery. There hasn’t been an uncontested cause on MS only educated guesses and assumptions on the cause. Although, there hasn’t been a true cause, but there been consists associations that share a link with MS genetics and environment. MS is not listed as a hereditary disease.
Studies show that UVB rays are responsible for this effect. The first step in UV skin carcinogenesis (creation of cancer) involves DNA damage. Occasional mistakes of DNA repairs lead to the integration of incorrect bases into the genetic material. The DNA that is left unrepaired may disrupt cellular processes by disrupting the DNA and RNA synthesizing machineries with incorrect genetic sequenses. These mistakes result in mutation leading to loss or inappropriate expression of affected genes.

It is considered as one of the serious and aggressive diseases. The disease is very hard to be diagnosed. And till now no such cure has been known for handling this disease. However, there are such treatments like surgery and chemotherapy that can help you to lessen the harmful effects of this disease.
