What are tumor markers and why are they needed?<\/strong><\/h3>\n

Tumor markers<\/a> \u2014 are specific substances (proteins, enzymes, genes, DNA fragments) that may appear in the blood, urine, or other biological fluids in response to tumor growth. Some of them are produced by the tumor cells themselves, others are produced as the body's response to the presence of a tumor.<\/p>\n

Traditionally, the most well-known markers are PSA (prostate cancer), CA-125<\/a> (ovarian cancer), CEA (colorectal cancer). However, in recent years, science has been new generations of tumor markers<\/strong>, which are more sensitive, specific and allow for the diagnosis of cancer in the early stages.<\/p>\n

What is the difference between new tumor markers?<\/strong><\/h3>\n

Unlike the classic ones, new tumor markers are often molecular in nature<\/strong> are gene fragments, microRNAs, mutations, or protein complexes that more accurately indicate the type of tumor, stage of the disease, and even the prognosis for treatment.<\/p>\n
