What are the strongest chemotherapy drugs?

Doxorubicin (Adriamycin) is one of the most powerful chemotherapy drugs ever invented. It can kill cancer cells at every point in their life cycle, and it’s used to treat a wide variety of cancers. Unfortunately, the drug can also damage heart cells, so a patient can’t take it indefinitely.

Ionizing radiation directly affects DNA structure by inducing DNA breaks, particularly, DSBs. Secondary effects are the generation of reactive oxygen species (ROS) that oxidize proteins and lipids, and also induce several damages to DNA, like generation of abasic sites and single strand breaks (SSB).

Does radiation therapy change your DNA?

Radiation may alter the DNA within any cell. Cell damage and death that result from mutations in somatic cells occur only in the organism in which the mutation occurred and are therefore termed somatic or nonheritable effects. Cancer is the most notable long-term somatic effect.
