Cancer cells can also cause defects in the cellular pathways of apoptosis (programmed cell death). As most chemotherapy drugs kill cancer cells in this manner, defective apoptosis allows survival of these cells, making them resistant. Many chemotherapy drugs also cause DNA damage, which can be repaired by enzymes in the cell that carry out DNA ...
The phenomenon first came to light because of the large number of breast cancer survivors who complained of changes in memory, fluency, and other cognitive abilities that impeded their ability to function as they had pre-chemotherapy. [2] Although the causes and existence of post-chemotherapy cognitive impairment have been a subject of debate ...
Radiation therapy is used mainly in the treatment of cancer. Radiation therapy can be used to cure, care or shrink tumors that are interfering with quality of life. Sometimes radiation therapy is used alone; other times it is used in conjunction with chemotherapy and surgery.
Cancer treatments are a wide range of treatments available for the many different types of cancer, with each cancer type needing its own specific treatment. [1] Treatments can include surgery, chemotherapy, radiation therapy, hormonal therapy, targeted therapy including small-molecule drugs or monoclonal antibodies, [2] and PARP inhibitors such as olaparib.

Radiation hormesis is the conjecture that a low level of ionizing radiation (i.e., near the level of Earth's natural background radiation) helps "immunize" cells against DNA damage from other causes (such as free radicals or larger doses of ionizing radiation), and decreases the risk of cancer. The theory proposes that such low levels activate ...
“Having counseled thousands of patients through their breast cancer diagnosis, I was fully aware of how nondiscriminatory this disease could be.” ... every major chemotherapy and radiation ...
But because HPV-cancer patients tend to live longer, they may end up dealing with the unpleasant side effects of treatment for longer, too. Treatment may include surgery, radiation and chemotherapy.
Residential exposure to radon gas, for example, has similar cancer risks as passive smoking. Radiation is a more potent source of cancer when combined with other cancer-causing agents, such as radon plus tobacco smoke. Radiation can cause cancer in most parts of the body, in all animals and at any age.
