Nuclear medicine is a branch of medicine that uses radioactive substances to diagnose or treat various diseases.<\/p>\n

This approach involves the administration of radiopharmaceuticals, radioactive compounds designed to target specific tissues in the body.<\/p>\n

Molecular biology in oncology studies the molecular basis of cancer, focusing on how normal cellular processes become deregulated and give rise to tumor formation. This involves analyzing DNA, RNA, and proteins to identify key alterations in cancer cells.<\/p>\n

In general, cancer cells exhibit significant alterations in fundamental biological processes. One of these is uncontrolled cell proliferation, driven by mutations in genes that regulate the cell cycle. Tumor cells can also evade apoptosis, a programmed cell death mechanism that eliminates damaged or defective cells, allowing them to survive even under adverse conditions.<\/p>\n

Another crucial aspect is angiogenesis, in which cancer cells stimulate the formation of new blood vessels to supply themselves with oxygen and nutrients, facilitating their growth. Finally, tumor cells possess the ability to spread throughout the body, a process known as metastasis, which is one of the leading causes of cancer-related deaths.<\/p>\n

Molecular biology uses advanced tools to study cancer at the genetic, transcriptomic, and proteomic levels. Broadly speaking, this means it can identify specific mutations in the DNA of cells, analyze gene expression levels, and obtain information about protein profiles that contribute to the abnormal behavior of malignant cells.<\/p>\n

Molecular oncology represents the future of cancer medicine by combining advanced knowledge of molecular biology and nuclear medicine, enabling the development of more effective and less invasive treatments.<\/p>\n
