2. What is laser therapy?
Laser therapy uses a super-intense narrow
beam of light to kill cancer cells while leaving
normal cells intact. Tumour cells absorb
different wavelengths of light to healthy ones.
Tumor cells can thus be targeted by selecting
the appropriate laser wavelength. One part of
your body is the only one that laser therapy
targets locally.
Lasers can also be employed in various types of
local treatment, such as photodynamic therapy
and laser interstitial thermal therapy, or LITT,
similar to hyperthermia. In this article, we will
learn everything about how Cancer is treated
with laser treatment and about the famous
immunologist Dr. Kanury Rao. So, let's get
started!

3. How Are Lasers Used in Cancer Treatment?
Light Amplification by Stimulated Emission of
Radiation, or LASER, is the abbreviation. Laser light is
distinct from ordinary light. Light from the sun or a light
bulb has different wavelengths and travels in all
directions. Contrarily, laser light can be focused into a
very small beam and has a single, high-energy
wavelength. It is hence both potent and accurate.
They provide accurate surgical results, which may entail
procedures like tissue removal or eye surgery. They
resemble lasers in some ways but have the ability to slice
into tissue with a scalpel-like edge. Heat to destroy small
areas (like tumours) or to make light-sensitive drugs
active.
Laser therapy is frequently administered using an
endoscope, a narrow, illuminated tube to examine
tissues inside the body. Flexible endoscopes transfer
light to the therapy site via optical fibers, tiny fibers used
singly or in bundles. It is introduced through a bodily
entrance such as the mouth, nose, anus, or vagina. A
tumor is then accurately sliced or destroyed using laser
light.
