The study showed that patients who held their
breath during radiation therapy had only a 1.4 percent rate of ischemic heart disease after 8 years of follow up and an estimated rate of 3.6 percent after 10 years.
The gadolinium's net positive charge would be able to absorb excess electrons, which tend to recombine with hydroxyl radicals — corrosive molecules
formed during radiation therapy against a tumor — and eliminate their cancer - killing effects.
Researchers are experimenting with two ways to use gold nanoparticles — in one case, to reduce the collateral damage
caused during radiation therapy while increasing effectiveness, and in another, as the targets of laser beams to help kill tumor cells.
Acupuncture has been shown to decrease these side effects allowing the patient to be able to swallow, eat and drink normally, protect the health of the teeth and gums and reduce the incidence of infections, pain and swelling in the mouth and
throat during radiation therapy.
Other factors come into play too, such as how much tissue was removed during a lumpectomy, or what the extent of damage was
during radiation therapy.
