A rising CEA level may be the first sign of cancer return, and may show up months before other studies or patient symptoms would raise concern.
In a scientific experiment, the following design elements are vital: 1. A falsifiable hypothesis - the question you are trying to answer (the hypothesis) must have a definitive "true" result and a definitive "false" result. For instance, a hypothesis may read "Drug X results in longer remission periods for cancer patients." The null hypothesis to this (the "hypothesis is false" result) is "Drug X does not result in longer remission periods for cancer patients." 2. The study must be statistically valid. When designing an experiment, you need to have enough data to conclude a "true hypothesis" result is real and not just because you got lucky and by chance found data to support a "true hypothesis" result. This will dictate the number of subjects studied as well as a general time frame for the study. 3. The data collection methods must be validated. If you are testing for cancer remission in breast cancer patients, you would use lymph node biopsies or mammograms to look for evidence of cancer resurgence; you would not use a blood chemistry test as the test wouldn't find the cancer even if it was there.
nicotine in tobacco from cigarettes... can make cells mutate which is cancer
If a human is exposed to radiation the may get radiation sickness, and cancer (although it can be used to treat cancer)
Abnormalities of the genetic materials are the only known cause of cancer. Errors in DNA replication and heritability of the genetic diseases are the cause of cancer during birth stage. Excessive ultraviolet radiation, any harmful infectious agents, tobacco smokes or chemicals are responsible for the abnormalities of genetic materials. Genes which promote cancer are called oncogenes. They are activated in cancer Cells. Tumor suppressive genes are not activated in the cancer Cells. For that reason programmed cell death and hyper active division and growth of Cells cannot be prevented. Inaccurate DNA replication, irregular Cell cycle, damaging the immune system are the major symptoms of cancer.
cancer his soul
Once treatment for the cancer has begun, CEA tests have a valuable role in monitoring the patient's progress.
Once a person gets prostate cancer once, the chances of it recurring are very high. Constant vigilance is necessary to watch for it to reappear.
Genetic testing for the breast cancer genes is doing via blood testing. Previous counseling is a normal requirement.
The CEA test is not a screening test for cancer. It is not useful for detecting the presence of cancer. Many cancers do not produce an increased CEA level.
Chemoprevention
yes
Yes, they fight cancer so of course they fund PPL who works with detecting cancer of different kinds in both men and women.
The medical side of dosage and testing certainly does.
cancer diseases
Colon cancer screening using fecal occult blood testing is an example of secondary prevention. By detecting colon cancer early, in this case by detecting the presence of blood in the stool, the patient may be able to obtain access to treatment that can slow or halt the development of colon cancer.
As far as is known, no cure for cancer has been found. Many discoveries may have been made through animal testing to bring us closer to a cure.
There are many side-effects to testing in animals such as permanent brain damage, cancer, and even death.
