3 Basic CLL Treatment Options • CCTreatment
CLL Treatment – Chronic lymphocytic leukemia, or CLL cancer, is a type of leukemia that typically affects older adults. This disease begins...Cancer Immunology - Acquired & Innate Immune System
The immune system can be divided into two main branches: the innate immune system and the acquired immune system.The Amazing Keto Diet and Cancer
When it comes to keto diet and cancer, the ketogenic diet has been shown to stop cancer growth, and in some cases, even shrink tumors.Today's detection methods can't determine the location of mutated and cancer cells in the body. Sometimes, in cancer detection, scientists are limited to testing blood or saliva samples for specific biological markers that correlate with cancer cells anywhere in the body. Once detected, a biopsy helps determine if cancerous cells invade healthy tissue.
Therefore, the detection process requires two invasive procedures: a test to determine whether cancer is present and a biopsy to confirm the presence of cancerous tissue. It is akin to finding a needle in a haystack: you must search through all the hay before you know if the hand exists.
An earlier diagnosis is required to detect cancer early when it is most easily treated and cured. However, this comes with significant caveats: the test must be able to distinguish between healthy cells and cancerous or pre-cancerous cells before they become visibly abnormal or symptomatic. Since researchers have yet to discover a foolproof biological marker to identify cancer cells, no such test is available.
Early cancer detection is thus limited to that determined by medical imaging, which detects physical abnormalities. Similarly, no test can determine the location of cancerous cells in the body. While some biological markers can indicate their presence, they cannot pinpoint where in the body they are located.
Cancer cells share many common traits with healthy, normal cells.
A pathologist must histologically examine the cell structure and confirm malignancy (cancerous cells) to confirm that an abnormality is due to cancerous cells. The only way to get this information is through surgery or biopsy.
Preliminary tests that show promise for detecting cancer without invasive procedures include:
Most current detection methods rely on identifying known biological markers for cancer, and these markers must be present in abnormally high numbers before they can indicate the presence of cancer. These tests are subject to false positives because other conditions may elevate marker levels. The same applies to screening tests for
early signs of cancer in healthy people. An elevated marker level is not definitive proof of cancer. Further biological testing is required to make an accurate diagnosis.
It is important to note that while there are many screening tests for various cancers available, there is no test that can detect all forms of cancer with equal accuracy.
Primary care physicians or specialists, such as general or gynecological oncologists, administer cancer screenings.
The National Cancer Institute recommends some cancer screening tests based on the patient's age, gender, and family history.
