Cancer Markers
There, I said it - the big C word. No one wants to hear it. You could possess a spouse and children member who has it, be a survivor yourself, or know someone who has died from it.
Since I have PBC (major biliary cirrhosis) I am concerned about liver cancer. I have blood tests just about every so several months to keep an eye on my liver enzyme levels. There's a high incidence of liver cancer resulting from individuals who have had liver cirrhosis.
You may well have been curious how doctors can tell what stage of cancer a person has.
Alpha-fetoprotein or AFP is a type of tumor marker which is utilized to diagnose cancer. These markers are employed to determine which stage of cancer a patient has. Tumor markers are substances (mostly proteins) that happen to be created by the system or by the tumor itself in response to cancer.
A high reading of specific proteins in an urine or blood sample may possibly indicate an additional aggressive cancer. Commonly, the higher the resulting number of your marker, the higher the stage of cancer.
Where symptoms suggest cancer in a patient, urine and blood samples are taken and submitted to a laboratory to become tested for cancer tumor marker levels.
The results assist the physician in determining if a patient has cancer. They can also help diagnose the type of cancer the patient has.
Cancer markers also are practical in determining the prognosis for your patient. They're also utilised to check to see if cancer has returned after remission.
A biopsy is taken once a diagnosis of cancer has been made, and again tumor markers can help to determine the amount of cancer that's present inside the patient's physique.
Advanced cancer is indicated by higher tumor marker levels as well as the prognosis is less good.
With the help of cancer markers, a doctor can then determine the best treatment for your patient.
Kinds of Cancer Markers
Some from the most common cancer markers (AFP) are employed for diagnosing the following cancers:
Liver
Ovarian
Breast
Gastrointestinal
Pancreatic
Lung
Colon
Prostate
Cancer research is ongoing in hopes to discover tumor markers for other varieties of cancers.
Not just one tumor marker is applied for all cancers, and not all cancers have tumor markers that work specifically for their diagnosis and treatment.
Once cancer treatment has been started by a patient, they will need to have further testing with tumor markers to see if their particular treatment is working.
If the tumor marker level declines, it generally is definitely an indication that the current treatment is working.
If the level increases or stays the same, the physician may well try a different form of treatment.
It's important that a sure amount of time has passed between cancer marker testing to give the treatment a chance to work around the tumor.
Drawbacks of Cancer Markers
You will find only a few cancer markers that happen to be able to find cancer while in the early stages. In fact, there are actually specified noncancerous ailments which can contribute to a high tumor marker level.
On occasion, cancer marker levels could not be elevated in a person who really has cancer. It can be important that all tests are taken into consideration, which includes a complete physical examination, history in the patient, other laboratory tests and scans.
Another drawback of testing with markers is that often you get a false favourable. There are actually a few factors that might contribute to an inaccurate lab test. Specified medications can alter the results of blood and urine tests, which include Vitamin C, Naproxen Sodium or Tylenol. Some antibiotics can also affect the tests.
False positives rates for cancer marker tests are typically 5 per cent. For other false positives or false negatives and their causes go to this link.
Personally, I have lost a boss to cancer from smoking. It was not lung, but nose cancer. He was way too young to die, and was a very kind man. He was a chain smoker.
I am glad that research continues on these varieties of markers to help in detecting cancer cells early on so a person has a better chance of surviving.
If you have peculiar symptoms, breast changes, weight loss, uncommon bleeding, unexplained fatigue, gnawing pain, indigestion, changes in lymph nodes, depression, or persistent cough or sore that will not heal, go to see your doctor. It's better to become tested early rather than wait until it can be too late to deal with it.
