Nanotechnology for curing cancer
Transcript of Nanotechnology for curing cancer
uncontrollable division and growth of cells which form malignant tumors
What is nanotechnology?
is the manipulation of matter at the atomic and molecular scale to create materials with new and advanced properties.
Nanotechnology for cancer treatment
To prove that nanotechnology has a great potential for cancer treatment and can be more effective in comparison with traditional methods
November 22, 2013
X-rays, Gamma rays and Charged Particles
shrink tumors and kill cancer cells.
Delivered by a machine
From radioactive material placed
the body near cancer cells
Radiation therapy can damage normal cells, leading to
Chemotherapy uses drugs that reach
of the body:
Cancer cells + Normal cells
Body is exposed to
(up to 113°F) to damage and kill cancer cells.
However, organs located
next to the tumor
can be damaged as well.
Hyperthermia may result in side effects, such as
burns, blisters, diarrhea, nausea, cardiac and vascular disorders.
Advantages of nanomedicine in comparison with traditional methods:
method for cancer treatment which is believed to
replace traditional methods
in the nearest future
such as Radiotherapy,chemotherapy, hyperthermia and surgery have considerable
in cancer treatment
