The oncogenesis process is caused by these mutations in the genetic material of normal cells, which alter the normal balance between proliferation and cell death. As a result there is an uncontrolled cell division and an evolutionary process of these cells through natural selection within the organism. Rapid and uncontrolled reproduction of cells can produce benign tumors and some types of these tumors can become malignant, which is what is known as cancer. Benign tumors do not spread to distant parts of the body or invade other tissues, and usually do not pose a threat to life unless they compress vital structures or have some physiological activity (for example, that they are capable of producing a hormone) . Malignant tumors are able to invade other organs, spread to distant places (a process known as metastasis) and become a threat to life.

Why does the cell use proteasomes or lysosomes to destroy misfolded proteins or proteins that are no longer needed? Destruction
vladimir1956 [14]

      That's right, what really happens is that the cell needs a "trash can", just like we do, because sometimes, things can go wrong along the process.

      The processes that the lysosomes can be involved are quite a lot, but the main one is the protein making. Why? Well, it's simple, there's a chance of mistake in each part of a protein our cells make through all the process, and when this happens, the cell recognizes it before this protein goes outside the cell, after this recognition, some flags are put in it to mark it.

       This mark will work in a way that the protein will go into the lysosome, and in a lysosome, there are several kinds of enzymes, so this protein can be degrated into little components again, the amino acids, and these can be used again in the process of making a new one. This is the process of recycling the protein, whether it's a misfolded protein or even the ones that the body won't need it for now.
