What form can an anti-cancer drug take?

An anti-cancer drug can indeed take the form of a radioactive substance. Radioactive substances are used in a form of treatment known as radiotherapy, where they help target and kill cancer cells. These substances emit radiation that damages the DNA within cancer cells, preventing them from growing and dividing. This method is particularly useful for certain types of cancer and can be an effective part of a broader treatment plan.

While anti-cancer drugs can also be found in other forms, such as chemical solutions, pills, or even natural compounds, the nature of the drug is not restricted to any single form. Therefore, it is important to recognize that treatments for cancer can be diverse and include various forms, particularly the use of radioactive substances.
