Modern approaches to the development of anticancer drugs

Cancer cannot be spoken of as a single disease, and a substance that would cure all types of cancer does not exist and cannot exist. Maybe your medicine will be active against 10% of forms of cancer of a certain tissue. Does it make sense to develop such a drug?

Genetically modified virus for early cancer diagnosis

Biotechnologists have taught the herpes virus to recognize cancer cells. The mutant virus infects atypical cells, which causes them to turn green and glow. According to herpetic "fireflies", scientists find tumors and metastases.

Delivery of drugs in microcapsules from the customer's cells

Packaging of medicines in containers with a diameter of 1-2 microns, obtained from the membranes of the patient's own cells, will allow for targeted delivery of drugs and "deceive" the immune and excretory systems.
