kasvajastest

Kasvajastest is a term used in medical contexts to describe a method or set of methods for detecting tumors or malignancies in the human body. It is used in screening, diagnostic evaluation, and monitoring of cancer risk, presence, progression, and response to treatment.

The methods encompassed by kasvajastest include imaging techniques such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET). It also covers laboratory tests for tumor-derived substances, such as biomarkers in blood, genetic or molecular markers, and circulating tumor DNA. Tissue-based approaches, including needle biopsy or surgical biopsy with histopathology and immunohistochemistry, are also part of kasvajastest. In recent years, liquid biopsy, which analyzes tumor-derived material in body fluids, has emerged as a non-invasive option within this framework.

Kasvajastest is used based on the type of suspected cancer, patient risk factors, symptoms, and prior results. It can aid in initial suspicion, confirmation of diagnosis, staging, treatment planning, and monitoring of treatment response or recurrence.

Interpretation of kasvajastest results depends on the pre-test probability and the overall clinical picture. Tests have varying sensitivity and specificity, and false positives or negatives can occur. Some tumors remain difficult to detect early, and non-invasive tests may be complemented by invasive procedures to establish a definitive diagnosis.

Advances in kasvajastest focus on improved accuracy, reduced invasiveness, and earlier detection through novel imaging, biomarkers, and multi-analyte tests. See also cancer screening, tumor markers, biopsy, radiology, and liquid biopsy.
