How does cancer develop?

Cancer is thought to develop as a consequence of genetic damage in normal cells. The damage can be congenital (10-15 percent of cancer cases) or be caused by, for example, external factors. The cell contains genes which in turn contain germ plasma (DNA) that determines how the cell’s proteins are to be produced. Cancer develops when a string of mutations take place in genes that govern the cell’s ability to grow and divide. These mutations often lead to an overstimulation of cell growth a

Radiotherapy

Radiotherapy is usually given to supplement the surgical procedure and to reduce the risk of local spread. In some cancers, radiotherapy without surgery may suffice. Radiation therapy utilizes radioactive radiation that destroys cancer cells and shrinks the tumors by exposing cancer cells to radiation damage. Even healthy tissue is destroyed, but with modern technology healthy tissue can be better saved. Cancer cells tend to divide faster than healthy cells, so they are particularly suscep
